Product details
Overview
TPC13AHM3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for high-reliability overvoltage protection of sensitive electronics. It features a breakdown voltage of 12.4–13.7 V at 1 mA, clamping voltage of 18.2 V at 82.4 A peak pulse current, and operates across -65 °C to +185 °C junction temperature range. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive powertrain control modules.
For engineers reviewing the TPC13AHM3_A/H datasheet, TPC13AHM3_A/H pinout, TPC13AHM3_A/H application, or TPC13AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, low-profile 1.1 mm height, uni-directional polarity, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response time and low incremental surge resistance. Its unidirectional architecture enables integration into DC power rails where reverse conduction must be blocked while providing robust clamping during positive transients.
The device is rated for 1500 W peak pulse power with a 10/1000 µs waveform and supports 82.4 A peak pulse current. It meets JESD201 Class 2 whisker test requirements and is halogen-free, RoHS-compliant, and qualified per AEC-Q101 for automotive under-hood applications.

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 peak power (400 W), SMA package, 13 V VBR, 21.5 V VC at 18.6 A | Not AEC-Q101 qualified; limited to commercial/industrial use; lower surge current handling | Select when cost sensitivity outweighs automotive qualification and higher surge immunity needs |
| TPC13AHE3_A/H | Same electrical specs, identical TO-277A package, but HM3 vs HE3 suffix indicates different revision-level process controls and traceability | No functional difference; HE3 variant may have alternate material sourcing or minor internal process variation | Prefer TPC13AHM3_A/H for new designs requiring latest revision and full AEC-Q101 documentation package |
Compared with SMAJ13A and TPC13AHE3_A/H, the TPC13AHM3_A/H delivers superior surge robustness (1500 W vs 400 W), automotive qualification, and tighter clamping (18.2 V vs 21.5 V), making it optimal for safety-critical 12 V systems where thermal margin and long-term reliability are mandatory.

FAQ
What is the clamping voltage of the TPC13AHM3_A/H under maximum surge conditions?
The TPC13AHM3_A/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 82.4 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components remain within safe operating voltage limits during transient events. The TPC13AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPC13AHM3_A/H suitable for automotive applications?
Yes, the TPC13AHM3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power supplies. Its TO-277A package, halogen-free construction, and JESD201 Class 2 whisker resistance further validate its suitability for automotive production use. The TPC13AHM3_A/H meets all required stress tests for automotive-grade reliability.
What does the "HM3" suffix in TPC13AHM3_A/H indicate?
The "HM3" suffix in TPC13AHM3_A/H identifies a halogen-free, RoHS-compliant, AEC-Q101-qualified version manufactured per Vishay's controlled revision "A". It specifies matte tin-plated terminals compliant with J-STD-002 and JESD22-B102, and confirms compliance with JESD201 Class 2 whisker testing. The TPC13AHM3_A/H is distinct from non-HM3 variants in material content, qualification scope, and traceability documentation.
How does the dual-cathode configuration of the TPC13AHM3_A/H improve performance?
The dual-cathode (Terminals 1 and 2) configuration in the TPC13AHM3_A/H provides parallel current paths during clamping, reducing effective surge resistance and improving thermal dissipation across the die. This design lowers VC overshoot and enhances reliability under repetitive surge conditions. In the TPC13AHM3_A/H, both cathodes are internally bonded and electrically identical, enabling flexible PCB layout and higher current sharing than single-terminal equivalents.
What is the maximum reverse leakage current of the TPC13AHM3_A/H at its stand-off voltage?
The TPC13AHM3_A/H exhibits a maximum reverse leakage current (IR) of 2.0 µA at its stand-off voltage (VWM) of 11.1 V and ambient temperature of 25 °C. At elevated junction temperature (TJ = 150 °C), leakage increases to a maximum of 10 µA - still well within safe margins for low-power MCU and sensor interface protection. This low leakage ensures minimal impact on system quiescent current in battery-powered applications using the TPC13AHM3_A/H.
