Product details
Overview
P4SMA10AHE3/61 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 14.5 V maximum clamping voltage at 27.6 A peak pulse current, 8.55 V stand-off voltage, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P4SMA10AHE3/61 datasheet, P4SMA10AHE3/61 pinout, P4SMA10AHE3/61 application, or P4SMA10AHE3/61 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA10AHE3/61 operates as a unidirectional avalanche-clamping device with glass-passivated junction, responding to transient overvoltages within nanoseconds. Its breakdown voltage is specified at 9.5–10.5 V (1 mA test current), and it maintains stable clamping performance up to 150 °C junction temperature.
Thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation under repetitive surge conditions when mounted per recommended pad layout. It meets J-STD-020 MSL Level 1 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 9.5–10.5 V at 1 mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage (VC) | 14.5 V at 27.6 A IPPM - limits downstream circuit voltage during 10/1000 µs surge events |
| Peak Pulse Power (PPPM) | 400 W - energy-handling capability under standardized 10/1000 µs waveform at TA = 25 °C |
| Peak Pulse Current (IPPM) | 27.6 A - maximum non-repetitive surge current the device safely clamps without failure |
| Junction Temperature Range | −65 to +150 °C - supports operation in under-hood automotive and industrial ambient environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; cathode indicated by band on body; RoHS-compliant and halogen-free (HE3 suffix).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMA package, 10 V VBR range, but rated for 400 W with 8.3 ms half-sine surge (not 10/1000 µs); no AEC-Q101 qualification | Targeted at commercial/industrial power supplies rather than automotive systems | Select SMAJ10A only if AEC-Q101 compliance is not required and surge profile matches 8.3 ms waveform |
| 1.5SMC10A | Higher-power SMC package (1500 W), same 10 V VBR, but larger footprint (7.11 × 6.22 mm vs. SMA's 4.93 × 3.99 mm) | Suitable for high-energy industrial mains protection where board space allows | Choose 1.5SMC10A when surge energy exceeds 400 W capability and PCB layout accommodates larger SMC outline |
Compared with SMAJ10A and 1.5SMC10A, the P4SMA10AHE3/61 uniquely combines AEC-Q101 qualification, compact SMA footprint, and precise 10 V-class clamping in a single-source automotive-grade solution - making it optimal for space-constrained, safety-critical vehicle subsystems.

FAQ
What is the clamping voltage of P4SMA10AHE3/61 at its rated peak pulse current?
The P4SMA10AHE3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value ensures downstream 12 V or 5 V ICs remain within safe operating limits during transient events. The clamping performance is guaranteed across the full −65 °C to +150 °C junction temperature range, and the device maintains this specification after AEC-Q101 qualification stress testing.
Is P4SMA10AHE3/61 suitable for automotive applications?
Yes, P4SMA10AHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use via the HE3 suffix. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per AEC standards. Its 150 °C max junction temperature, MSL Level 1 reflow compatibility, and glass-passivated junction make it appropriate for under-hood and cabin-mounted ECUs, such as those in ADAS sensors and body control modules.
What does the "HE3" suffix mean in P4SMA10AHE3/61?
The "HE3" suffix in P4SMA10AHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability requirements. It also confirms compliance with JESD201 Class 2 whisker resistance and UL 94 V-0 flammability rating for the molding compound - distinguishing it from commercial-grade E3 or halogen-free HM3 variants.
How does P4SMA10AHE3/61 differ from bidirectional versions like P4SMA10CA?
P4SMA10AHE3/61 is unidirectional and features a cathode band for polarity identification, clamping only when cathode voltage exceeds anode by ≥9.5 V. In contrast, P4SMA10CA is bidirectional with symmetric breakdown in both directions and no polarity marking. The unidirectional P4SMA10AHE3/61 offers lower leakage at VWM (10 µA vs. 100 µA for P4SMA10CA) and is preferred for DC-biased lines like power rails, whereas P4SMA10CA suits AC or differential signal paths.
What is the thermal resistance of P4SMA10AHE3/61, and how does it affect layout design?
P4SMA10AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain safe operation under repetitive surges, the datasheet specifies mounting on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal. Reducing pad size or omitting thermal vias increases junction temperature, potentially derating peak power below 400 W - so PCB layout must follow Vishay's recommended footprint in Document 88367.
