Product details
Overview
P4SMA82AHE3/61 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 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V maximum clamping voltage (VC) at 3.5 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 P4SMA82AHE3/61 datasheet, P4SMA82AHE3/61 pinout, P4SMA82AHE3/61 application, or P4SMA82AHE3/61 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below VWM (70.1 V) and rapidly switches to low-impedance conduction above VBR (min 77.9 V) to divert transient energy. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
It delivers 400 W peak pulse power per 10/1000 µs waveform when mounted on 5.0 mm × 5.0 mm copper pads, with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead). The device is rated for -65 °C to +150 °C operating junction temperature and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V to 86.1 V at 1 mA test current - defines precise clamping onset threshold under standardized conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ82A-E3/5A | Same VBR range (77.9–86.1 V), identical SMA package, but rated for 400 W only up to 82 V; no AEC-Q101 qualification | Commercial-grade use only; not suitable for automotive OEM or Tier 1 production | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive qualification |
| 1.5SMC82AHE3/A | Higher 1500 W rating, DO-214AB (SMC) package (larger footprint), same VBR/VC, AEC-Q101 qualified | Used where higher surge margin is needed (e.g., alternator output lines), but requires PCB layout change | Choose when system-level surge testing exceeds 400 W requirements and board space allows larger SMC footprint |
Compared with SMAJ82A-E3/5A, P4SMA82AHE3/61 adds AEC-Q101 validation and tighter MSL control; versus 1.5SMC82AHE3/A, it trades surge capacity for compact SMA layout - making P4SMA82AHE3/61 optimal for space-constrained automotive modules needing certified reliability.

FAQ
What is the clamping voltage of P4SMA82AHE3/61 under a 400 W transient?
The P4SMA82AHE3/61 clamps to a maximum of 113 V when subjected to its rated 400 W peak pulse power with a 10/1000 µs waveform at 3.5 A. This value is measured under standard test conditions using 5.0 mm × 5.0 mm copper pads per terminal and represents the upper limit of voltage seen by downstream components during such an event. The P4SMA82AHE3/61 maintains this clamping performance across its specified operating temperature range.
Is P4SMA82AHE3/61 suitable for automotive applications?
Yes, P4SMA82AHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use with suffix "HE3", indicating RoHS-compliant construction and full stress-test validation including temperature cycling, high-temperature reverse bias, and ESD. It is deployed in engine control units, body control modules, and ADAS sensor interfaces where reliability under harsh thermal and electrical conditions is mandatory. The P4SMA82AHE3/61 meets all relevant automotive qualification requirements per the Vishay documentation.
What is the standoff voltage rating for P4SMA82AHE3/61?
The standoff voltage (VWM) for P4SMA82AHE3/61 is 70.1 V - the maximum DC or RMS voltage that can be continuously applied without exceeding 1 µA reverse leakage current. This value ensures the P4SMA82AHE3/61 remains non-conductive during normal operation in 12 V or 24 V automotive and industrial systems, activating only during overvoltage events exceeding its breakdown threshold.
Does P4SMA82AHE3/61 have a bidirectional variant?
No, P4SMA82AHE3/61 is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same series use the "CA" suffix (e.g., P4SMA82CAHE3/61) and lack polarity marking. The P4SMA82AHE3/61 must be oriented correctly on PCBs with cathode toward the protected line; using it in reverse or substituting a bidirectional part without circuit review may compromise protection integrity.
What packaging format is used for P4SMA82AHE3/61?
P4SMA82AHE3/61 is supplied in 7-inch diameter plastic tape and reel, with 1800 units per reel (ordering code "/61"). The device uses standard EIA-481-compliant carrier tape, compatible with high-speed pick-and-place equipment. The SMA (DO-214AC) package has matte tin-plated leads meeting J-STD-002 solderability requirements, and the P4SMA82AHE3/61 is rated MSL Level 1 for unlimited floor life at ≤30 °C/60 % RH.
