Product details
Overview
TPSMC8.2AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 124 V maximum clamping voltage at 124 A peak pulse current, and operates up to +185 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the TPSMC8.2AHE3_B/I datasheet, TPSMC8.2AHE3_B/I pinout, TPSMC8.2AHE3_B/I application, or TPSMC8.2AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 124 V clamping performance at rated surge, thermal stability to 185 °C, and compatibility with automated SMT assembly using J-STD-002 soldering standards.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature reliability and low incremental surge resistance. Its junction design enables stable breakdown behavior across -65 °C to +185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device delivers 1500 W peak pulse power under 10/1000 µs waveform with 124 V clamping voltage at 124 A IPPM, and exhibits 0.056 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold shift over temperature in automotive and industrial environments.

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 | Lower PPPM (600 W), smaller SMB package (DO-214AA), 12.1 V clamping at 43.5 A IPPM | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing power rails only | Select when space-constrained layouts require smaller footprint and automotive qualification is not required |
| TPSMC8.2AHE3_B/H | Identical electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (850 pcs vs. 3500 pcs per reel) | No functional or application difference; same thermal, electrical, and mechanical behavior | Select when smaller reel quantity aligns with production batch size or SMT feeder constraints |
Compared with SMBJ8.0A, TPSMC8.2AHE3_B/I offers triple the surge power handling and automotive qualification; compared with TPSMC8.2AHE3_B/H, it provides identical protection performance in higher-volume reel format for scalable manufacturing.

FAQ
What is the clamping voltage of the TPSMC8.2AHE3_B/I at its rated peak pulse current?
The TPSMC8.2AHE3_B/I has a maximum clamping voltage (VC) of 124 V at its rated peak pulse current (IPPM) of 124 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during full-rated surge events. The TPSMC8.2AHE3_B/I maintains this clamping performance across its operational temperature range due to its low 0.056 %/°C VBR temperature coefficient.
Is the TPSMC8.2AHE3_B/I qualified for automotive applications?
Yes, the TPSMC8.2AHE3_B/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's datasheet (Doc. #88407, Rev. 19-Jan-2024). This qualification covers stress tests including high-temperature gate bias, humidity-assisted bias, temperature cycling, and accelerated life testing. The TPSMC8.2AHE3_B/I is intended for use in automotive subsystems such as body control modules, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical.
What does the "HE3" and "B/I" suffix mean in TPSMC8.2AHE3_B/I?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability. The "B/I" denotes revision level "B" and packaging in 13-inch tape-and-reel format containing 3500 units. This distinguishes TPSMC8.2AHE3_B/I from variants like TPSMC8.2AHE3_B/H (same revision, 7-inch reel, 850 units) and confirms full compliance with automotive and lead-free assembly requirements.
Can the TPSMC8.2AHE3_B/I be used in bidirectional protection circuits?
No, the TPSMC8.2AHE3_B/I is unidirectional only, as explicitly stated in the Vishay datasheet. It protects against positive-going transients on the cathode-connected line relative to anode (ground). For bidirectional protection-such as AC lines or data buses requiring suppression of both polarities-a separate bidirectional TVS like SMAJ8.0CA or a back-to-back unidirectional pair would be required. Using TPSMC8.2AHE3_B/I in reverse-biased configuration exceeds its specified reverse standoff voltage and risks permanent damage.
What is the maximum junction temperature rating for the TPSMC8.2AHE3_B/I?
The TPSMC8.2AHE3_B/I has a maximum junction temperature (TJ) rating of +185 °C, verified per Vishay's qualification testing and documented in the absolute maximum ratings table. This enables operation in high-ambient environments such as engine compartments or enclosed industrial enclosures without thermal derating. The device maintains specified electrical parameters-including VBR, VC, and leakage-up to this limit, supported by its passivated anisotropic rectifier structure and thermally robust SMC package.
