Product details
Overview
TPC11AHM3/86A 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 breakdown voltage of 10.5–11.6 V at 1.0 mA, 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 TPC11AHM3/86A datasheet, TPC11AHM3/86A pinout, TPC11AHM3/86A application, or TPC11AHM3/86A equivalent, key selection criteria include unidirectional surge clamping performance, AEC-Q101 qualification, low-profile 1.1 mm height, and compatibility with automated SMT placement on automotive-grade PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver fast response time and low incremental surge resistance. Its junction passivation enables stable operation at TJ = 185 °C, supporting under-hood automotive environments and high-temperature industrial control systems.
The device is rated for 10/1000 μs waveform peak power dissipation of 1500 W and exhibits a typical temperature coefficient of VBR at 0.067 %/°C. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing.

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 21.4 A | Not AEC-Q101 qualified; suitable only for commercial-grade consumer electronics | Select when cost sensitivity outweighs automotive reliability requirements and surge energy is lower |
| TPC11AHE3/86A | Same electrical specs, identical SMPC package, but HM3/86A suffix indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified revision | No functional difference; both meet same automotive qualification and thermal specs | Prefer TPC11AHM3/86A for new designs requiring documented halogen-free compliance and latest revision traceability |
Compared with SMAJ11A and TPC11AHE3/86A, the TPC11AHM3/86A delivers higher surge robustness (1500 W vs. 400 W), automotive qualification, and dual-cathode low-inductance layout-making it optimal for safety-critical 12 V rail and CAN protection where thermal margin and reliability are non-negotiable.

FAQ
What is the clamping voltage of the TPC11AHM3/86A under a 10/1000 μs surge?
The TPC11AHM3/86A has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 96.2 A under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components like microcontrollers and transceivers in automotive and industrial systems.
Is the TPC11AHM3/86A qualified for automotive applications?
Yes, the TPC11AHM3/86A is AEC-Q101 qualified and explicitly rated for automotive use. Its 185 °C maximum junction temperature, MSL Level 1 rating, JESD 201 Class 2 whisker resistance, and halogen-free construction meet stringent requirements for under-hood and body electronics. The "HM3" suffix confirms compliance with automotive material and process standards.
How does the dual-cathode configuration of the TPC11AHM3/86A improve performance?
The TPC11AHM3/86A features two cathode terminals (Terminals 1 and 2) in parallel, reducing effective package inductance and enabling more uniform current sharing during high-dI/dt transients. This configuration lowers total clamping impedance compared to single-cathode equivalents, resulting in tighter voltage control and improved protection for fast-rising surges like ESD or load dump edges.
What is the meaning of the "HM3/86A" suffix in TPC11AHM3/86A?
The "HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101 qualified SMPC package variant, while "86A" specifies the tape-and-reel packaging format (7-inch reel, 1500 units per reel, plastic carrier tape). This full suffix identifies the exact manufacturing revision, environmental compliance, and logistics configuration required for traceable automotive procurement.
Can the TPC11AHM3/86A replace older TPC11A variants in existing designs?
Yes, the TPC11AHM3/86A is a direct replacement for earlier TPC11A versions in the same SMPC package, with identical pinout, electrical characteristics, and thermal performance. Its HM3 revision adds halogen-free and enhanced whisker resistance, making it suitable for new designs and backward-compatible upgrades where automotive compliance and long-term supply assurance are priorities.
