Product details

Overview

TPC8.2HM3/87A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial surge protection. It features 8.2 V nominal breakdown voltage (V_BR), 7.02 V stand-off voltage (V_WM), clamping voltage of 12.1 V at 200 A peak pulse current, and operates up to +185 °C junction temperature.

For engineers reviewing the TPC8.2HM3/87A datasheet, TPC8.2HM3/87A pinout, TPC8.2HM3/87A application, or TPC8.2HM3/87A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, unidirectional polarity, and suitability for protecting MOSFETs, sensor signal lines, and IC power rails against inductive switching transients.

Technical Context

This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive surge stress. Its 10/1000 μs waveform capability delivers 1500 W peak pulse power and 200 A I_PPM, while maintaining low incremental surge resistance and fast response time.

The device is rated for -65 °C to +185 °C operating junction temperature and meets JESD201 Class 2 whisker resistance. Its SMPC (TO-277A) package supports automated placement and provides UL 94 V-0 compliant molding compound with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (Nom)	8.2 V - precise breakdown threshold ensures reliable triggering before downstream component damage
V_WM	7.02 V - maximum continuous reverse voltage without leakage exceeding 200 μA
V_C @ I_PPM	12.1 V - clamping voltage at 200 A limits protected circuit stress during 10/1000 μs surge
P_PPM	1500 W - peak pulse power handling capacity for automotive-level load dump and inductive kick events
T_J max	+185 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures
Package	SMPC (TO-277A) - surface-mount, low-profile (1.1 mm height), AEC-Q101 qualified, MSL Level 1
Polarity	Unidirectional - protects DC-biased lines such as power supplies and sensor bias rails

Pinout & Package

TPC8.2HM3/87A is housed in a 3-terminal SMPC (TO-277A) package with cathode band marking on terminal 1. The package has a compact footprint (4.80 × 3.70 mm) and 1.1 mm typical height, optimized for space-constrained PCB layouts and automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 (Cathode)	Anode-side reference node	Connected to protected line; cathode band identifies polarity for correct orientation during placement
2 (Cathode)	Main cathode connection	Parallel path for surge current return; both cathodes are internally tied and must be routed to common ground plane
3 (Anode)	Ground reference input	Low-inductance connection point to system ground; critical for minimizing clamping overshoot during fast transients

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock testing
Junction passivation	Stabilizes V_BR over lifetime and prevents parametric drift under thermal stress
MSL Level 1 rating	Enables unlimited floor life and reflow compatibility without dry-pack requirements
Low profile (1.1 mm)	Reduces board clearance issues in stacked or shielded modules and enables conformal coating coverage
UL 94 V-0 molding	Ensures flame retardancy in safety-critical applications including EV battery management and ADAS subsystems

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ8.0A	Lower P_PPM (400 W), SMA package (higher profile, lower thermal mass)	Not AEC-Q101 qualified; limited to commercial/industrial use	Select when cost sensitivity outweighs automotive qualification and surge energy demands
TPC8.2HM3	Same electrical specs and SMPC package; differs only in revision code (no functional change)	Identical application scope and layout compatibility	Preferred for new designs requiring latest manufacturing revision and traceability

Compared with SMAJ8.0A and TPC8.2HM3, the TPC8.2HM3/87A offers identical core protection performance but adds full AEC-Q101 compliance and enhanced thermal robustness-critical for automotive power distribution and industrial systems requiring long-term field reliability.

FAQ

What is the clamping voltage of the TPC8.2HM3/87A at its rated peak pulse current?

The TPC8.2HM3/87A has a maximum clamping voltage (V_C) of 12.1 V when subjected to its rated 200 A peak pulse current (I_PPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable voltage limiting during surge events. The TPC8.2HM3/87A maintains this clamping performance across its full operating temperature range, supporting robust design margin for protected ICs and MOSFETs.

Is the TPC8.2HM3/87A qualified for automotive applications?

Yes, the TPC8.2HM3/87A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for automotive powertrain, body electronics, and ADAS applications. Its SMPC (TO-277A) package meets JESD201 Class 2 whisker resistance and MSL Level 1 requirements. The TPC8.2HM3/87A also complies with material restrictions per Vishay's standard for halogen-free, RoHS-compliant components.

How does the TPC8.2HM3/87A differ from the base TPC8.2A part number?

The TPC8.2HM3/87A is a specific packaging and revision variant of the TPC8.2A: "HM3" denotes halogen-free, RoHS-compliant, AEC-Q101-qualified construction in SMPC (TO-277A) package, and "/87A" indicates the revision code per Vishay's internal documentation. Electrically and thermally, the TPC8.2HM3/87A matches the TPC8.2A specification sheet values-including V_BR = 8.2 V, V_WM = 7.02 V, and V_C = 12.1 V-ensuring full functional equivalence.

What is the maximum reverse leakage current of the TPC8.2HM3/87A at its stand-off voltage?

At 25 °C, the TPC8.2HM3/87A exhibits a maximum reverse leakage current (I_R) of 200 μA when biased at its stand-off voltage (V_WM) of 7.02 V. At elevated temperature (T_J = 150 °C), leakage increases to a maximum of 2000 μA-still within safe operational limits for most power rail and signal line protection applications. This low leakage preserves system efficiency and avoids false triggering in high-impedance sensing circuits.

Can the TPC8.2HM3/87A be used in bidirectional configurations?

No, the TPC8.2HM3/87A is strictly unidirectional and must be oriented with its cathodes toward the protected line and anode to ground. It is not rated for reverse conduction or symmetrical clamping. For bidirectional protection, Vishay offers complementary devices such as the TPC8.2CA series. Using the TPC8.2HM3/87A in reverse bias risks permanent degradation due to lack of specified reverse standoff or clamping behavior.
