Product details
Overview
P6SMB82AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB82AHE3_A/H datasheet, P6SMB82AHE3_A/H pinout, P6SMB82AHE3_A/H application, or P6SMB82AHE3_A/H equivalent, this device is selected for robust overvoltage protection where AEC-Q101 qualification, low-profile SMB packaging, and fast response (<1 ns) are required in space-constrained DC power rails and automotive control modules.
Technical Context
The P6SMB82AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified VBR range (77.9–86.1 V), with cathode-band polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at 70.1 V).
It delivers 600 W transient suppression under standardized 10/1000 µs surge conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature in PCB-mounted configurations with minimum 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 margin below 113 V clamping threshold; suitable where higher standoff is needed. | Select when system nominal voltage exceeds 70 V and tighter clamping is not critical. |
| 1.5SMC82A | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; no AEC-Q101 qualification. | Requires more PCB area; not validated for automotive temperature cycling or humidity testing. | Choose for cost-sensitive industrial designs where automotive qualification is unnecessary. |
Compared with SMAJ85A-E3/52 and 1.5SMC82A, the P6SMB82AHE3_A/H provides optimal balance of AEC-Q101 compliance, tight 70.1 V standoff, and 113 V clamping in the smallest qualified SMB footprint - making it preferred for space-constrained automotive and high-reliability embedded systems.

FAQ
What is the clamping voltage of P6SMB82AHE3_A/H at its rated peak pulse current?
The P6SMB82AHE3_A/H 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 is measured per standard test methods and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB82AHE3_A/H maintains this clamping performance across its qualified operating temperature range.
Is P6SMB82AHE3_A/H suitable for automotive applications?
Yes, P6SMB82AHE3_A/H is AEC-Q101 qualified and specifically designated for automotive use with suffix "HE3" indicating RoHS-compliant and AEC-Q101-qualified construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation - making P6SMB82AHE3_A/H appropriate for under-hood and cabin control modules.
What does the "_A/H" suffix in P6SMB82AHE3_A/H indicate?
The "_A/H" suffix in P6SMB82AHE3_A/H denotes packaging and revision coding: "A" refers to the standard revision level per Vishay's internal documentation, and "H" specifies 7-inch plastic tape-and-reel delivery (750 units per reel). This matches the ordering format defined in Vishay's P6SMB Series datasheet Document Number 88370.
How does P6SMB82AHE3_A/H differ from bidirectional variants like P6SMB82CA?
P6SMB82AHE3_A/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where current flows in one direction. In contrast, P6SMB82CA is bidirectional, symmetrical in both directions, and lacks polarity marking - suited for AC signal lines or differential buses. The P6SMB82AHE3_A/H offers lower leakage and tighter VBR tolerance than its bidirectional counterpart.
What is the thermal resistance of P6SMB82AHE3_A/H and how does it affect PCB layout?
P6SMB82AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe junction temperatures under repetitive surges, PCB layout must use minimum 5.0 mm × 5.0 mm copper pads per terminal as specified in the datasheet - ensuring P6SMB82AHE3_A/H remains within its 150 °C TJ limit during sustained operation.
