Product details
Overview
P6SMB82AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 70.1 V stand-off voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB82AHE3_A/I datasheet, P6SMB82AHE3_A/I pinout, P6SMB82AHE3_A/I application, or P6SMB82AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by transient overvoltage events. Its glass-passivated junction enables fast response time (<1 ns), low leakage (<1 μA at VWM), and stable breakdown behavior under repetitive 10/1000 μs surges at 0.01% duty cycle.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits +0.105 %/°C temperature coefficient of VBR, and achieves thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout - critical for thermal management in compact PCB designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85A-E3/52 | Higher VWM (72.2 V), higher VC (121 V), same SMB package and 600 W rating | Less tight clamping margin; suitable where 121 V clamping is acceptable | Select when tighter VBR tolerance is not required and higher VWM margin is preferred |
| 1.5SMC82A | Same VWM/VBR/VC specs, but in larger SMC (DO-214AB) package with higher RθJA (60 °C/W) | Requires more PCB area; better thermal performance only with larger pads | Choose only if existing layout uses SMC footprint or higher thermal mass is available |
Compared with SMAJ85A-E3/52 and 1.5SMC82A, P6SMB82AHE3_A/I delivers tighter VBR tolerance (±5%), AEC-Q101 qualification, and optimized thermal design for space-constrained automotive modules - making it preferred for new designs targeting functional safety compliance.

FAQ
What is the clamping voltage of P6SMB82AHE3_A/I at its rated peak pulse current?
The P6SMB82AHE3_A/I has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on protected circuits during transient events and is measured with the device mounted on 0.2" × 0.2" copper pads per the datasheet test condition. The P6SMB82AHE3_A/I maintains this clamping performance across its specified operating temperature range.
Is P6SMB82AHE3_A/I qualified for automotive applications?
Yes, P6SMB82AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in Vishay's ordering information and mechanical data tables. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for under-hood and chassis-mounted automotive electronics. The P6SMB82AHE3_A/I meets these requirements without derating in standard mounting configurations.
What does the "_A/I" suffix mean in P6SMB82AHE3_A/I?
The "_A/I" suffix in P6SMB82AHE3_A/I denotes packaging configuration: "A" indicates the device is unidirectional, and "I" specifies 13-inch diameter plastic tape and reel delivery (3200 units per reel). This matches Vishay's ordering convention where "H" = 7-inch reel and "I" = 13-inch reel. The P6SMB82AHE3_A/I is therefore a unidirectional, AEC-Q101-qualified TVS diode supplied in high-volume SMT-ready format.
How does P6SMB82AHE3_A/I compare to bidirectional variants like P6SMB82CA?
P6SMB82AHE3_A/I is unidirectional with cathode marking and asymmetric conduction - it conducts only during reverse overvoltage, whereas P6SMB82CA is bidirectional and symmetrical for AC line protection. The P6SMB82AHE3_A/I offers tighter VBR tolerance (±5%) and AEC-Q101 qualification, while P6SMB82CA lacks automotive qualification and has higher leakage in both directions. They are not interchangeable without circuit redesign.
What is the thermal resistance of P6SMB82AHE3_A/I in typical PCB mounting?
The P6SMB82AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal, as defined in the Vishay datasheet. This value assumes still-air conditions and directly impacts safe power dissipation limits - for example, at 50 °C ambient, the device can continuously dissipate up to 5.0 W only if heatsinking is enhanced beyond standard layout. The P6SMB82AHE3_A/I thermal performance is optimized for short-duration surge events rather than steady-state power.
