Product details
Overview
TPC13AHM3/86A 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 electronics protection. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), clamping voltage of 18.2 V at 82.4 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC13AHM3/86A datasheet, TPC13AHM3/86A pinout, TPC13AHM3/86A application, or TPC13AHM3/86A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, unidirectional polarity, and suitability for inductive load switching transients on MOSFETs and sensor signal lines.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time under 10/1000 µs transients. Its junction passivation enables stable operation at TJ = 185 °C, supporting automotive-grade thermal reliability without derating up to that limit.
The device is rated for 200 A non-repetitive forward surge current (IFSM) and exhibits 3.5 V maximum forward voltage at 100 A, confirming robust conduction capability during clamping. Its 1.0 mA test current for VBR measurement aligns with ANSI/IEEE C62.35 standards for transient suppression devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), SMA package (larger footprint, 2.2 mm height), same VBR range but higher VC (21.5 V) | Not AEC-Q101 qualified; limited to commercial/industrial use where automotive reliability not required | Select when cost sensitivity outweighs power handling and automotive qualification needs |
| TPC13AHE3/86A | Same electrical specs and TO-277A package, but HM3/86A suffix indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified version; HE3/86A denotes alternate packaging code | No functional difference; identical performance and qualification - differs only in tape/reel delivery mode and traceability coding | Choose TPC13AHM3/86A for verified halogen-free compliance and preferred logistics handling per Vishay's preferred P/N scheme |
Compared with SMAJ13A and TPC13AHE3/86A, the TPC13AHM3/86A delivers superior surge robustness (1500 W vs. 400 W), automotive-grade reliability (AEC-Q101), and space savings (1.1 mm height), while maintaining identical VBR and clamping behavior - making it optimal for next-gen automotive and high-density industrial designs.

FAQ
What is the breakdown voltage tolerance for TPC13AHM3/86A?
The TPC13AHM3/86A has a breakdown voltage (VBR) range of 12.4 V (min) to 13.7 V (max) at 1.0 mA test current, yielding ±5 % nominal tolerance around 13.0 V. This tight tolerance ensures predictable clamping onset and consistent protection margins across production lots and temperature ranges.
Is TPC13AHM3/86A suitable for bidirectional transient protection?
No, TPC13AHM3/86A is unidirectional only - it conducts and clamps only for positive transients relative to its anode (Pin 3). For bidirectional protection, a separate device such as the SMBJ13CA or dual-diode array would be required; TPC13AHM3/86A must be used with correct polarity orientation in DC circuits.
What is the maximum clamping voltage of TPC13AHM3/86A under surge conditions?
The TPC13AHM3/86A clamps to a maximum of 18.2 V at its rated peak pulse current of 82.4 A (10/1000 µs waveform). This value is guaranteed per datasheet Fig. 3 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does TPC13AHM3/86A require derating at elevated ambient temperatures?
Yes - while the junction temperature can reach +185 °C, peak pulse power (PPPM) must be derated above TA = 25 °C per Figure 2 in the datasheet. At 125 °C ambient, PPPM is reduced to approximately 750 W, and at 150 °C, it drops to ~500 W, preserving device reliability under sustained thermal stress.
What does the "HM3/86A" suffix indicate in TPC13AHM3/86A?
The "HM3/86A" suffix identifies the packaging and compliance version: HM3 denotes halogen-free, RoHS-compliant construction with matte tin plating and JESD201 Class 2 whisker resistance; "86A" specifies the revision code and tape-and-reel delivery format (7-inch reel, 1500 units), per Vishay's ordering nomenclature in Document 89056.
