Product details
Overview
P6SMB160AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides clamping protection for power rails and signal lines in automotive and industrial electronics against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB160AHM3_A/I datasheet, P6SMB160AHM3_A/I pinout, P6SMB160AHM3_A/I application, or P6SMB160AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, 219 V maximum clamping voltage at 2.7 A IPPM, low thermal resistance (RθJL = 20 °C/W), and halogen-free RoHS-compliant construction with matte tin leads.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VBR (152–168 V), then avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 136 V).
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), supports 100 A IFSM surge current (8.3 ms half-sine), and delivers repeatable clamping performance under repetitive 0.01% duty-cycle pulses - critical for automotive power supply rail protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A (10/1000 μs) - Actual voltage seen by protected IC/MOSFET during worst-case transient |
| PPPM (Peak Pulse Power) | 600 W - Sustains standardized 10/1000 μs surge without failure; enables robust protection in harsh environments |
| ID (Reverse Leakage) | ≤1.0 μA at 136 V - Negligible standby current draw; avoids loading sensitive sensor or low-power circuits |
| TJ max. | 150 °C - Enables reliable operation in under-hood automotive or enclosed industrial enclosures |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking on unidirectional devices. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; carries surge current to reference plane |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs here during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive applications including engine control units and body electronics requiring extended temperature and life-cycle reliability |
| Halogen-free & RoHS-compliant | Meets environmental compliance mandates for global OEMs without compromising surge robustness or thermal performance |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients common in 12 V/24 V vehicle systems and industrial motor drives |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes voltage overshoot during clamping - critical for protecting 150 V-rated MOSFETs and gate drivers |
| MSL Level 1 moisture sensitivity | Enables direct placement into reflow ovens without baking; reduces manufacturing overhead and risk of popcorning |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, clamping surges within 1 ns response time.

IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt ESD (IEC 61000-4-2 ±8 kV contact) and cable-induced surges. Use Value: Sub-μA leakage preserves signal integrity; 219 V clamping prevents op-amp saturation or ADC input damage. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
Use Scenario: Secondary-side protection on AC/DC power supplies feeding telecom base station boards exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on +48 V bias rail, coordinated with upstream MOVs and fuses.

Use Scenario: Overvoltage suppression on primary-side bulk capacitor inputs in universal-input (90–264 VAC) adapters. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to ground, absorbing switching spikes from MOSFET turn-off. Use Value: 136 V VWM allows safe operation across full input range; 20 °C/W RθJL enables efficient heat dissipation on PCB copper pads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM/VBR/VC specs; SMA package (smaller footprint, higher RθJA = 140 °C/W); non-AEC-Q101; RoHS-compliant but not halogen-free | Limited to commercial-grade consumer/industrial use; unsuitable for under-hood automotive due to thermal and qualification gaps | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC160AHE3_A | Same electrical specs; larger SMC (DO-214AB) package (higher power handling margin); AEC-Q101 qualified; halogen-free | Better thermal performance (RθJL = 15 °C/W) and higher IFSM (200 A); requires larger PCB area | Select when enhanced surge endurance or higher ambient temperature derating is required |
Compared with P6SMB160AHM3_A/I, SMAJ160A-E3/52 trades automotive qualification and thermal robustness for smaller size, while 1.5SMC160AHE3_A offers superior thermal and surge margins at the cost of footprint - making P6SMB160AHM3_A/I the optimal balance of AEC-Q101 compliance, SMB form factor, and 600 W capability.

FAQ
What is the clamping voltage of P6SMB160AHM3_A/I at its rated peak pulse current?
The P6SMB160AHM3_A/I has a maximum clamping voltage (VC) of 219 V when subjected to its specified peak pulse current (IPPM) of 2.7 A under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C with recommended 0.2" × 0.2" copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P6SMB160AHM3_A/I suitable for automotive applications?
Yes, P6SMB160AHM3_A/I is AEC-Q101 qualified (denoted by the HM3 suffix and "_B" or "_D" revision coding per datasheet), tested for temperature cycling, high-temperature reverse bias, and ESD robustness. Its 150 °C maximum junction temperature and halogen-free RoHS compliance make it appropriate for under-hood and body-control module applications.
What does the "HM3_A/I" suffix indicate in P6SMB160AHM3_A/I?
In P6SMB160AHM3_A/I, "HM3" signifies halogen-free, RoHS-compliant, and AEC-Q101 qualified construction; "A" denotes the revision code per Vishay's internal documentation; "I" specifies packaging in 13-inch diameter plastic tape and reel (3200 units per reel), optimized for high-volume SMT placement.
How does P6SMB160AHM3_A/I compare to bidirectional TVS diodes in the same series?
P6SMB160AHM3_A/I is unidirectional and features a cathode band marking; it conducts only in reverse avalanche mode and blocks forward current. Bidirectional variants (e.g., P6SMB160CA) lack polarity marking and suppress transients in both directions - making them suitable for AC lines or differential signals, whereas P6SMB160AHM3_A/I is intended for DC rail protection with defined ground reference.
What is the thermal resistance from junction to lead (RθJL) for P6SMB160AHM3_A/I?
The P6SMB160AHM3_A/I has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, measured under standard conditions. This low value enables effective heat transfer from the silicon die to the PCB copper pads via the leads, supporting reliable operation at elevated ambient temperatures and during repetitive surge events.
