Product details
Overview
P4SMA160A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 160 V standoff voltage (VWM), 171 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 1.4 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA160A-M3/61 datasheet, P4SMA160A-M3/61 pinout, P4SMA160A-M3/61 application, or P4SMA160A-M3/61 equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal resistance (RθJA = 120 °C/W), unidirectional polarity marking, halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification status.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown above its VBR threshold. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while low incremental surge resistance minimizes voltage overshoot during transient events.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. Mounted on 0.2" × 0.2" copper pads, it delivers 400 W peak pulse power up to 91 V and 300 W above 91 V, with 1.4 A IPPM at VC = 219 V under standardized 10/1000 µs waveform conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for normal circuit operation. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; defines reliable triggering threshold for transient suppression. |
| VC (Clamping Voltage) | 219 V at IPPM = 1.4 A - Peak voltage seen by protected circuit during worst-case 10/1000 µs surge; must be below downstream device's absolute max rating. |
| PPPM (Peak Pulse Power) | 400 W (≤91 V), 300 W (>91 V) - Surge energy handling capacity under standard waveform; determines survivability of common lightning/inductive-switching transients. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Ultra-low leakage ensures minimal power loss and signal integrity degradation in standby or low-power states. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing and layout for thermal management under sustained power dissipation. |
| Polarity | Unidirectional - Cathode marked by band; blocks forward current until VF ≈ 3.5 V at 25 A, enabling DC rail protection without forward conduction issues. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant (M3 suffix), MSL Level 1 (260 °C reflow peak), matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to lower-potential side (e.g., GND or return rail); completes clamping loop during transient events. |
| Cathode | Avalanche conduction terminal / Surge sink node | Marked by black band; connected to higher-potential line (e.g., 136 V rail); conducts surge current into anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) on 136 V DC rails without failure. |
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%), low leakage (<1 µA), and long-term reliability under thermal cycling and humidity stress. |
| Low profile SMA package | 0.208" × 0.157" footprint supports high-density PCB layouts and automated SMT placement with JEDEC-standard tape-and-reel (61 code = 1800 pcs/reel). |
| AEC-Q101 qualified (P4SMA160A variant) | Validated for automotive power electronics including body control modules and ADAS sensor power inputs requiring extended temperature and life-cycle validation. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-4101D/21 and EU Directive 2015/863; eliminates brominated flame retardants while maintaining UL 94 V-0 flammability rating. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Suppresses switching spikes from relay coils and solenoid drivers in 12–48 V DC industrial PLC outputs. IC Role / Device Role / Timing Role: Unidirectional TVS placed across relay coil terminals to clamp inductive kickback and prevent MOSFET gate oxide damage. Use Value: 219 V clamping voltage ensures safe margin below 250 V-rated power MOSFETs, while 1.4 A IPPM handles typical 100–500 mJ coil energy releases. |
Use Scenario: Protects LIN bus transceivers and microcontroller I/O pins from load dump and jump-start transients in vehicle BCMs. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V supply rail upstream of LDO regulators, activated within <1 ns to limit voltage excursion during 60 V/100 ms load dump events. Use Value: AEC-Q101 qualification and 150 °C TJ max guarantee operation in under-hood environments; 136 V VWM avoids false triggering during normal battery fluctuations. |
| Telecom AC/DC Adapter Input Stage | Sensor Signal Line Protection (Industrial) |
Use Scenario: Shields primary-side controller ICs and optocouplers from line surges entering via AC input rectifier stage in Class II telecom adapters. IC Role / Device Role / Timing Role: Primary-side unidirectional TVS between bridge rectifier output and bulk capacitor, absorbing differential-mode surges before they reach PWM controller. Use Value: 400 W PPPM withstands combination wave surges (1.2/50 µs voltage + 8/20 µs current); 120 °C/W RθJA allows thermal design with minimal copper area. |
Use Scenario: Guards analog front-end inputs of pressure/temperature sensors exposed to ESD and cable discharge events in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ ≈ 40 pF at VWM) placed inline with 4–20 mA or 0–10 V sensor outputs to shunt ESD without distorting signal bandwidth. Use Value: 1.0 µA ID at 136 V prevents loading of high-impedance sensor circuits; SMA package enables placement directly at connector interface for shortest possible trace length. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM/VBR/VC specs but SMB (DO-214AA) package - 20 % larger footprint, 100 W higher PPPM (600 W), RθJA = 90 °C/W. | Better thermal performance and surge margin; requires PCB redesign due to larger body and different pad layout. | Select when higher surge immunity or improved thermal headroom is required and board space permits SMB package. |
| 1.5SMC160A | Same electrical specs but SMC (DO-214AB) package - 30 % larger than SMA, 1500 W PPPM, RθJA = 65 °C/W, 7.5 A IPPM. | Designed for high-energy industrial mains protection; overqualified for low-power signal-line use; incompatible pinout and mounting. | Choose only for high-reliability 136 V DC bus protection where 1500 W surge rating and lower thermal resistance justify larger footprint and cost. |
Compared with SMBJ160A and 1.5SMC160A, P4SMA160A-M3/61 offers optimal balance of compact SMA footprint, halogen-free compliance, and sufficient 400 W surge rating for space-constrained industrial and automotive sub-systems - without requiring PCB rework or over-engineering.

FAQ
What is the clamping voltage of P4SMA160A-M3/61 at its rated peak pulse current?
The P4SMA160A-M3/61 has a maximum clamping voltage (VC) of 219 V at 1.4 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet 88367, and defines the highest voltage the protected circuit will experience during a worst-case transient event. Engineers must verify this VC remains below the absolute maximum voltage rating of downstream components such as MOSFETs or controllers.
Is P4SMA160A-M3/61 AEC-Q101 qualified?
Yes, the P4SMA160A-M3/61 is AEC-Q101 qualified, as confirmed in the "MECHANICAL DATA" section and footnote (1) on page 3 of Vishay document 88367, which states "_A is available for P4SMA6.8(C)A to P4SMA220(C)A, AEC-Q101 qualified". The "A" suffix in P4SMA160A-M3/61 explicitly denotes this qualification, making it suitable for automotive applications including body electronics and sensor power domains.
What does the "M3" suffix indicate in P4SMA160A-M3/61?
The "M3" suffix in P4SMA160A-M3/61 indicates halogen-free, RoHS-compliant construction per IPC-4101D/21 and EU Directive 2015/863, with matte tin-plated leads meeting J-STD-002 solderability requirements. It also confirms compliance with JESD201 Class 2 whisker resistance testing. This distinguishes it from the "E3" (RoHS-compliant but not halogen-free) and "HM3" (halogen-free + AEC-Q101) variants.
How does the thermal resistance of P4SMA160A-M3/61 affect PCB layout?
The P4SMA160A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" copper pads per Figure 5. To maintain TJ ≤ 150 °C under 3.3 W steady-state power dissipation, designers must allocate ≥5 mm × 5 mm copper area per terminal and consider thermal vias. Reducing pad size increases RθJA, risking premature thermal shutdown or parametric shift during repetitive surges.
Can P4SMA160A-M3/61 be used in bidirectional configurations?
No, P4SMA160A-M3/61 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional versions use the "CA" suffix (e.g., P4SMA160CA). Using P4SMA160A-M3/61 in bidirectional applications would allow forward conduction on negative transients, potentially damaging the device or failing to clamp. For AC line or differential-signal protection, select the CA variant or pair unidirectional devices back-to-back.
