Product details
Overview
P4SMA8.2AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for clamping inductive switching transients and ESD events on power and signal lines. It features a 7.79 V to 8.61 V breakdown voltage (VBR) at 10 mA, 7.02 V maximum stand-off voltage (VWM), 12.1 V clamping voltage (VC) at 33.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P4SMA8.2AHE3/61 datasheet, P4SMA8.2AHE3/61 pinout, P4SMA8.2AHE3/61 application, or P4SMA8.2AHE3/61 equivalent, this AEC-Q101-qualified device supports automotive-grade surge protection design where low-leakage (<200 µA at VWM), fast response time, and stable thermal performance up to 150 °C junction temperature are required.
Technical Context
The P4SMA8.2AHE3/61 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range. Its glass-passivated junction ensures consistent VBR tolerance (±5%) and low incremental surge resistance, enabling precise clamping during transient events.
Designed for SMA (DO-214AC) surface-mount assembly, it delivers 400 W peak pulse power under standardized 10/1000 µs waveform conditions with derating above 25 °C ambient, and meets J-STD-020 MSL Level 1 reflow requirements with 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines reliable turn-on threshold for transient suppression |
| VWM | 7.02 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 12.1 V at 33.1 A - clamped voltage seen by protected circuit during 400 W transient |
| IPPM | 33.1 A - peak surge current capability with 10/1000 µs waveform, critical for IEC 61000-4-5 compliance |
| PPPM | 400 W - peak pulse power handling capacity, enabling robust protection against inductive kick and lightning surges |
| ID @ VWM | <200 µA - ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | 150 °C - extended junction temperature rating supports operation in under-hood automotive environments |
Pinout & Package

| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream ICs such as microcontrollers and CAN transceivers |
Applications
| Automotive Power Line Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting 12 V supply rails in automotive ECUs from load-dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and LDO input to clamp spikes before regulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Higher VWM (6.89 V), lower VC (12.0 V), same SMA package but larger SMB footprint (DO-214AA) | Requires PCB layout change; better suited for higher-energy 600 W applications | Select when higher peak power (600 W) and tighter VC tolerance are needed, accepting larger board area |
| 1.5SMC8.2A | Same VBR range, 1500 W rating, DO-214AB (SMC) package - 2.5× larger footprint and 3× higher thermal mass | Not suitable for space-constrained layouts; used where sustained surge duty cycle exceeds P4SMA capability | Choose for industrial motor drives needing repetitive 1.5 kW surge handling, not for automotive PCB miniaturization |
Compared with SMBJ8.0A and 1.5SMC8.2A, the P4SMA8.2AHE3/61 offers optimal balance of AEC-Q101 compliance, 400 W surge capacity, and minimal SMA footprint-making it preferred for automotive and portable electronics where board space, thermal profile, and qualification rigor are jointly constrained.

FAQ
What is the breakdown voltage tolerance for P4SMA8.2AHE3/61?
The P4SMA8.2AHE3/61 has a specified breakdown voltage range of 7.79 V to 8.61 V at 10 mA test current, corresponding to ±5% tolerance around the nominal 8.2 V rating. This tight VBR distribution ensures predictable clamping behavior across production lots and supports robust design margins in safety-critical automotive applications where the P4SMA8.2AHE3/61 is commonly deployed.
Is P4SMA8.2AHE3/61 suitable for bidirectional transient protection?
No, P4SMA8.2AHE3/61 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P4SMA8.2CA variant. Using P4SMA8.2AHE3/61 in bidirectional configurations risks forward conduction during positive transients, potentially damaging the device or failing to protect the circuit-so correct polarity orientation is essential when deploying the P4SMA8.2AHE3/61.
Does P4SMA8.2AHE3/61 meet automotive qualification standards?
Yes, P4SMA8.2AHE3/61 is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in Vishay's P4SMA datasheet (Rev. 09-Jan-2024, Doc. #88367). This qualification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock-validating its suitability for under-hood and chassis-mounted automotive electronics where the P4SMA8.2AHE3/61 is routinely applied.
What is the maximum clamping voltage of P4SMA8.2AHE3/61 under surge conditions?
The P4SMA8.2AHE3/61 exhibits a maximum clamping voltage (VC) of 12.1 V at 33.1 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standardized test conditions and represents the upper voltage limit imposed on protected circuitry during worst-case transient events-critical for ensuring downstream ICs like microcontrollers or CAN transceivers remain within absolute maximum ratings when the P4SMA8.2AHE3/61 is active.
How does the thermal resistance of P4SMA8.2AHE3/61 affect its power handling?
The P4SMA8.2AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W. When mounted on the recommended 0.2" × 0.2" copper pads, this allows safe dissipation of its 3.3 W steady-state power rating at 50 °C ambient. Under transient conditions, the device relies on thermal mass rather than steady-state conduction-so the RθJA value primarily governs continuous power derating, not the 400 W pulse rating of the P4SMA8.2AHE3/61.
