Product details
Overview
TPC10HM3/86A 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 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), clamping voltage of 14.5 V at 103 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC10HM3/86A datasheet, TPC10HM3/86A pinout, TPC10HM3/86A application, or TPC10HM3/86A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, unidirectional polarity, and suitability for protecting MOSFETs, sensor signal lines, and IC power rails against inductive switching transients.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive surge stress. Its design targets fast response time (<1 ns), low incremental surge resistance, and robust thermal performance up to 185 °C - critical for automotive under-hood and industrial motor drive environments.
The device uses a three-terminal SMPC (TO-277A) configuration with dual cathodes and a common anode, enabling symmetrical layout placement and enhanced PCB current handling. It meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance requirements, supporting automated SMT assembly without reflow degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), SMA package (2.5 mm height), VC = 16.0 V @ 24.7 A | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| TPC10AHM3_A | Same die, identical specs; differs only in reel packaging code (A vs. 86A) and revision marking | No functional or application difference - both meet same AEC-Q101, MSL Level 1, and thermal specs | Preferred for new designs requiring documented traceability to Vishay's latest HM3 revision and tape/reel logistics alignment |
Compared with SMAJ10A and TPC10AHM3_A, the TPC10HM3/86A delivers 3.75× higher peak power handling (1500 W vs. 400 W) and automotive qualification, while sharing identical electrical parameters and package footprint with TPC10AHM3_A - making it optimal for high-reliability 12 V system protection where surge energy and environmental ruggedness are critical.

FAQ
What is the exact breakdown voltage tolerance for TPC10HM3/86A?
The TPC10HM3/86A has a specified breakdown voltage (VBR) range of 9.5 V (min) to 10.5 V (max) at 1.0 mA test current, with a nominal value of 10.0 V. This ±5 % tolerance is confirmed in Vishay's official datasheet (Doc. #89056, Rev. 19-Apr-2022) and applies across the full operating temperature range. The TPC10HM3/86A maintains this specification under standard test conditions and supports consistent clamping behavior in production designs.
Is TPC10HM3/86A pin-compatible with other devices in the TPCxxA family?
Yes - all TPCxxA devices, including TPC10HM3/86A, share identical SMPC (TO-277A) package dimensions, pinout (dual cathode/anode), and mounting pad layout. However, electrical parameters such as VBR, VWM, and VC differ across the family; therefore, direct substitution requires verification of voltage ratings and clamping performance. The TPC10HM3/86A itself is not interchangeable with TPC12A or TPC15A without circuit-level validation.
Does TPC10HM3/86A support reflow soldering per J-STD-020?
Yes - the TPC10HM3/86A is rated for MSL Level 1 per J-STD-020, meaning it has unlimited floor life and withstands standard lead-free reflow profiles (peak temperature up to 260 °C) without preconditioning. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102, and the device passes JESD201 Class 2 whisker testing - confirming robust solder joint reliability for TPC10HM3/86A in high-volume SMT manufacturing.
What is the maximum clamping voltage of TPC10HM3/86A under surge conditions?
The maximum clamping voltage (VC) of TPC10HM3/86A is 14.5 V, measured at 103 A peak pulse current using a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Table "ELECTRICAL CHARACTERISTICS") and represents worst-case clamping under standardized surge testing. Designers must ensure downstream components tolerate ≤14.5 V transient exposure when using TPC10HM3/86A in protection schemes.
How does the dual-cathode configuration of TPC10HM3/86A improve surge performance?
The dual-cathode structure in the TPC10HM3/86A reduces effective series inductance and incremental surge resistance by providing parallel current paths during transient events. This results in faster voltage stabilization and tighter clamping - verified by lower VC versus single-cathode equivalents of comparable rating. The configuration is intrinsic to the SMPC (TO-277A) package and is fully leveraged in the TPC10HM3/86A's published 14.5 V clamping spec at 103 A.
