Product details
Overview
TPC11HM3/87A 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 surge protection. It features a 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V clamping voltage (VC) at 96.2 A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the TPC11HM3/87A datasheet, TPC11HM3/87A pinout, TPC11HM3/87A application, or TPC11HM3/87A equivalent, key selection criteria include its 185 °C junction temperature rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and unidirectional clamping behavior in space-constrained DC power rail and sensor line protection.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching transients and ESD events. Its unidirectional architecture provides forward conduction only during overvoltage clamping, with no reverse leakage beyond 5.0 μA at VWM and 10 μA at 150 °C.
The device operates across -65 °C to +185 °C and is rated for 200 A non-repetitive forward surge current (IFSM) under 8.3 ms half-sine conditions. Its thermal design supports high-power dissipation in compact layouts, validated per JESD201 Class 2 whisker testing and UL 94 V-0 molding compound compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 18.2 V at 21.9 A | Not suitable for automotive load dump; limited to low-energy ESD and lightning-induced surges | Select when cost-sensitive consumer designs require basic IEC 61000-4-2 protection without AEC-Q101 or 1500 W rating |
| TPC11AHM3_A | Same electrical specs and SMPC package; differs only in reel packaging code (A vs. 87A) and revision suffix | No functional difference; identical performance, qualification, and footprint | Preferred for new designs where Vishay's latest HM3 revision and tape/reel logistics align with production planning |
Compared with SMAJ11A and TPC11AHM3_A, the TPC11HM3/87A delivers higher surge robustness (1500 W vs. 400 W), automotive qualification, and lower clamping voltage - making it optimal for mission-critical 12 V systems where thermal margin and long-term reliability are prioritized over minimal BOM cost.

FAQ
What is the clamping voltage of the TPC11HM3/87A at its rated peak pulse current?
The TPC11HM3/87A has a maximum clamping voltage (VC) of 15.6 V at 96.2 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value ensures protected circuits remain below critical voltage thresholds during high-energy transients. The TPC11HM3/87A maintains this clamping performance across its full operating temperature range and after repeated surge events, as verified in AEC-Q101 stress testing.
Is the TPC11HM3/87A suitable for automotive under-hood applications?
Yes, the TPC11HM3/87A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood automotive applications such as engine control modules, transmission control units, and body control modules. Its SMPC package offers mechanical robustness and thermal performance validated for automotive thermal cycling and vibration requirements. The TPC11HM3/87A meets ISO 7637-2 Pulse 5a load dump immunity when properly mounted on thermally enhanced PCBs.
How does the dual-cathode configuration of the TPC11HM3/87A improve surge handling?
The TPC11HM3/87A uses a dual-cathode (Terminals 1 and 2) configuration within the SMPC (TO-277A) package to reduce dynamic impedance and distribute surge current more evenly across the silicon die. This lowers the effective VC under high-current transients and improves thermal spreading during repetitive pulses. Unlike single-terminal TVS devices, the TPC11HM3/87A's parallel cathode structure enhances current sharing and extends surge lifetime without requiring external paralleling. The design is intrinsic to the TPC11HM3/87A die layout and package interconnect.
What is the meaning of the "87A" suffix in TPC11HM3/87A?
The "87A" suffix in TPC11HM3/87A denotes the specific tape-and-reel packaging variant and revision code: "87" indicates the preferred reel size and orientation per Vishay's internal logistics coding, while "A" identifies the revision level of the HM3 halogen-free, RoHS-compliant, and AEC-Q101-qualified die version. It is not a functional variant - all electrical, thermal, and reliability specifications of the TPC11HM3/87A match those of TPC11AHM3_A and other HM3-suffixed parts in the same family.
Does the TPC11HM3/87A require derating at elevated ambient temperatures?
Yes, the TPC11HM3/87A requires derating of its peak pulse power (PPPM) above 25 °C ambient, per Figure 2 in Vishay document 89056. At 100 °C ambient, PPPM is reduced to approximately 70 % of the rated 1500 W. Derating is based on junction temperature limits and thermal resistance of the SMPC package. Designers must calculate actual TJ using board layout, copper area, and airflow to ensure the TPC11HM3/87A remains within its -65 °C to +185 °C operating range during worst-case surge events.
