Product details
Overview
TPC22HM3/86A 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 circuit protection. It features a breakdown voltage of 20.9–23.1 V at 1 mA, clamping voltage of 30.6 V at 49.0 A peak pulse current, and operates up to 185 °C junction temperature.
For engineers reviewing the TPC22HM3/86A datasheet, TPC22HM3/86A pinout, TPC22HM3/86A application, or TPC22HM3/86A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, 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 to deliver stable breakdown behavior and low incremental surge resistance. Its unidirectional architecture enables precise clamping on positive-going transients while maintaining low leakage (<1 μA at 18.8 V) across temperature.
The device is optimized for high-energy 10/1000 µs waveform suppression with 1500 W peak power rating and supports automated SMT placement due to matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 35.5 V at 11.3 A | Not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select when cost sensitivity outweighs power handling and automotive compliance requirements |
| TPC22A (non-HM3 suffix) | Same electrical specs but lacks halogen-free, RoHS-compliant, and JESD 201 Class 2 whisker testing certifications | Not approved for high-reliability automotive or medical-grade production | Choose TPC22HM3/86A when full AEC-Q101, RoHS, and whisker resistance are mandatory |
Compared with SMAJ22A and TPC22A, the TPC22HM3/86A delivers higher surge robustness (1500 W vs. 400 W), automotive qualification, and enhanced process reliability-making it the preferred choice for mission-critical 12 V/24 V power rail protection where field failure risk must be minimized.

FAQ
What is the breakdown voltage range of the TPC22HM3/86A?
The TPC22HM3/86A has a guaranteed breakdown voltage range of 20.9 V to 23.1 V at 1 mA test current, with a nominal value of 22.0 V. This specification ensures consistent clamping behavior across production lots and supports accurate overvoltage threshold design in 12 V and 24 V systems where the TPC22HM3/86A is deployed for transient suppression.
Is the TPC22HM3/86A suitable for automotive applications?
Yes, the TPC22HM3/86A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood and other high-reliability automotive applications. Its construction meets automotive material requirements, including halogen-free composition and JESD 201 Class 2 whisker resistance-key attributes confirmed for the TPC22HM3/86A in Vishay's official documentation.
What package type does the TPC22HM3/86A use?
The TPC22HM3/86A uses the SMPC (TO-277A) surface-mount package-a three-terminal, low-profile case with 1.1 mm typical height and JEDEC-compliant dimensions. The package features matte tin-plated leads, conforms to MSL Level 1, and includes a visible cathode band for polarity identification during automated placement of the TPC22HM3/86A.
How does the clamping voltage of the TPC22HM3/86A compare to its breakdown voltage?
The TPC22HM3/86A clamps at 30.6 V when subjected to its rated 49.0 A peak pulse current (10/1000 µs waveform), which is approximately 39 % above its nominal 22.0 V breakdown voltage. This controlled voltage margin ensures effective protection of downstream 24 V-rated components while maintaining sufficient headroom to avoid false triggering during normal operation of the TPC22HM3/86A.
Does the TPC22HM3/86A have any environmental compliance certifications?
Yes, the TPC22HM3/86A is halogen-free, RoHS-compliant, and passes JESD 201 Class 2 whisker testing. These certifications are explicitly tied to the HM3 suffix in the part number and are documented in Vishay's datasheet revision 19-Apr-2022 (Document Number: 89056). The TPC22HM3/86A meets all applicable environmental and reliability standards required for modern automotive and industrial production.
