Product details
Overview
P4SMA10A-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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA10A-M3/61 datasheet, P4SMA10A-M3/61 pinout, P4SMA10A-M3/61 application, or P4SMA10A-M3/61 equivalent, key selection criteria include unidirectional polarity, 10 V working voltage, 14.5 V clamping performance under 27.6 A surge, thermal resistance of 120 °C/W, and halogen-free RoHS-compliant M3 suffix construction.
Technical Context
The P4SMA10A-M3/61 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress transient overvoltages induced by inductive switching or ESD events. Its breakdown voltage is specified at 9.5–10.5 V with 1 mA test current, and it maintains stable clamping up to 150 °C junction temperature.
Designed for surface-mount assembly on standard 0.2" × 0.2" copper pads, the device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements. It is not AEC-Q101 qualified (suffix lacks HE3/HM3), but shares mechanical and electrical architecture with automotive-grade variants in the same P4SMA family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Avalanche onset range; ensures predictable turn-on during transients without premature leakage. |
| VC (Clamping Voltage) | 14.5 V at 27.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC-level overvoltage margining. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standardized 10/1000 µs waveform; enables robust protection against common surges. |
| ID (Reverse Leakage) | 10 µA max at 8.55 V - Low standby current minimizes power loss and avoids false triggering in high-impedance circuits. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area for thermal management at 3.3 W steady-state dissipation. |
| Polarity | Unidirectional - Cathode marked by band; blocks forward current until breakdown, suitable for DC-biased lines like power rails or unidirectional data paths. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal under forward bias | Connected to lower-potential side of protected line; must be routed with low-inductance trace for effective surge shunting. |
| Cathode | Current exit terminal under forward bias; marked with band | Connected to higher-potential side (e.g., VCC rail or signal source); defines directionality and clamping reference point. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) on 12 V systems without derating. |
| Glass passivated chip junction | Ensures long-term reliability and stable VBR drift under thermal cycling and humidity exposure per JESD22-A101. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without pre-baking or special handling; eliminates moisture-related popcorning risk. |
| Low profile SMA package | 0.208" length enables compact placement near connectors or IC pins, minimizing parasitic inductance in surge path. |

IC Role / Device Role / Timing Role: Placed across output capacitor to clamp voltage spikes exceeding 10 V standoff, limiting stress on downstream USB ports or PMICs. Use Value: 8.55 V VWM provides 15 % margin above nominal 5 V rail while allowing full clamping action before regulator overvoltage shutdown triggers. |
Use Scenario: Guarding RS-485 transceiver bus lines against lightning-induced surges in outdoor network equipment cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS installed between each differential line (A/B) and ground to limit common-mode transients without affecting differential signaling. Use Value: 120 °C/W RθJA allows direct mounting on FR4 with minimal copper, enabling cost-effective board-level protection without heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VWM (8.55 V) and VC (14.5 V), but SMB package (DO-214AA); 600 W PPPM rating; RθJA = 85 °C/W. | Higher power handling and better thermal performance, but 25 % larger footprint; requires revised pad layout. | Select when higher surge endurance or tighter thermal budget is required; not drop-in due to different package dimensions. |
| 1.5SMC10A | Same electrical specs (VWM, VBR, VC), but SMC (DO-214AB) package; 1500 W PPPM; RθJA = 50 °C/W; 1.5 kW rating. | Designed for high-energy transients (e.g., IEC 61000-4-5 Level 4); overqualified for typical board-level protection. | Choose only if system-level surge testing exceeds 400 W requirements; adds cost and board space without benefit for standard applications. |

FAQ
What is the maximum clamping voltage of the P4SMA10A-M3/61 under surge conditions?
The P4SMA10A-M3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the highest voltage the protected circuit will experience during a defined transient event. The P4SMA10A-M3/61 maintains this clamping performance across its rated junction temperature range of –65 °C to +150 °C.
Is the P4SMA10A-M3/61 suitable for automotive applications requiring AEC-Q101 qualification?
No, the P4SMA10A-M3/61 is not AEC-Q101 qualified. Its M3 suffix indicates halogen-free RoHS compliance and commercial-grade reliability, but AEC-Q101 qualification requires the HE3 or HM3 suffix (e.g., P4SMA10AHE3_A). For automotive use, engineers must select the AEC-Q101 variant - the P4SMA10A-M3/61 is intended for industrial and consumer applications where automotive qualification is not mandated.
What does the "/61" suffix indicate in P4SMA10A-M3/61?
"/61" denotes the packaging configuration: 7-inch diameter plastic tape and reel, with 1800 units per reel. This format is optimized for high-speed automated pick-and-place assembly. The P4SMA10A-M3/61 uses industry-standard EIA-481-D compliant carrier tape, ensuring compatibility with most SMT feeders and supporting traceable lot-controlled manufacturing.
How does the thermal resistance of the P4SMA10A-M3/61 affect PCB layout?
The P4SMA10A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads. To maintain safe operation at its 3.3 W steady-state power dissipation limit, designers must allocate sufficient copper area - doubling pad size reduces RθJA by ~25 %. The P4SMA10A-M3/61's thermal behavior is validated per JEDEC standards and assumes no additional heatsinking.
Can the P4SMA10A-M3/61 be used in bidirectional signal line protection?
No, the P4SMA10A-M3/61 is unidirectional only, as indicated by the "A" suffix (versus "CA" for bidirectional versions like P4SMA10CA). Using it on AC or bidirectional lines would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection, the P4SMA10CA-M3/61 must be selected - the P4SMA10A-M3/61 is strictly for DC-biased or single-polarity applications.
