Product details
Overview
TPC11HM3/86A 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 10.5–11.6 V at 1.0 mA test current, clamping voltage of 15.6 V at 96.2 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC11HM3/86A datasheet, TPC11HM3/86A pinout, TPC11HM3/86A application, or TPC11HM3/86A 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 achieve low incremental surge resistance and fast response time under 10/1000 μs surge conditions. Its unidirectional polarity and 1500 W peak pulse power rating enable robust clamping during repetitive or single-event transients in automotive power electronics.
The device is rated for -65 °C to +185 °C operating junction temperature, with a typical temperature coefficient of VBR at 0.067 %/°C. Its SMPC (TO-277A) package supports automated placement and meets UL 94 V-0 flammability requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 18.2 V at 21.6 A | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Choose SMAJ11A only when surge energy is lower and automotive qualification is not required. |
| TPC11A (non-HM3 suffix) | Same electrical specs but lacks halogen-free, RoHS-compliant, and AEC-Q101 qualification per HM3 revision | Not approved for automotive production; may require requalification for new designs | Select TPC11HM3/86A over TPC11A when compliance with automotive material and reliability standards is mandatory. |
Compared with SMAJ11A and TPC11A, TPC11HM3/86A delivers higher surge robustness (1500 W vs. 400 W), automotive-grade reliability (AEC-Q101), and tighter process control (HM3 suffix), making it the preferred choice for safety-critical 12 V rail protection in modern vehicle electronics.

FAQ
What is the clamping voltage of TPC11HM3/86A and how is it measured?
The clamping voltage of TPC11HM3/86A is 15.6 V, measured at 96.2 A peak pulse current using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device during standardized surge testing and directly determines the protection level afforded to downstream components. TPC11HM3/86A maintains this clamping performance across its full operating temperature range.
Is TPC11HM3/86A qualified for automotive applications?
Yes, TPC11HM3/86A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and body electronics applications. The HM3 suffix confirms halogen-free, RoHS-compliant construction and compliance with JESD201 Class 2 whisker testing. TPC11HM3/86A is explicitly listed in Vishay's AEC-Q101 qualified product list for transient voltage suppressors.
What does the "HM3" in TPC11HM3/86A signify?
The "HM3" suffix in TPC11HM3/86A denotes Vishay's revision code indicating halogen-free, RoHS-compliant materials, AEC-Q101 qualification, and compliance with JESD201 Class 2 whisker resistance. The "/86A" portion specifies tape-and-reel packaging in 7-inch reels with 1500-unit base quantity. This distinguishes TPC11HM3/86A from non-HM3 variants like TPC11A, which lack these certifications.
How does the dual-cathode configuration of TPC11HM3/86A improve performance?
The dual-cathode terminals (Pins 1 and 2) in TPC11HM3/86A provide parallel current paths that reduce effective surge resistance and improve thermal distribution during high-current transients. This configuration lowers clamping voltage overshoot and enhances reliability under repeated surge stress. Unlike single-cathode TVS devices, TPC11HM3/86A leverages its SMPC (TO-277A) layout to deliver more consistent 1500 W pulse handling.
Can TPC11HM3/86A replace SMAJ11A in existing designs?
TPC11HM3/86A is not a direct drop-in replacement for SMAJ11A due to different package (SMPC vs. SMA), higher power rating (1500 W vs. 400 W), and distinct pinout (3-terminal vs. 2-terminal). While both suppress 11 V transients, TPC11HM3/86A requires PCB layout changes and offers superior automotive qualification. Redesign validation is required before substitution in any application.
