Product details
Overview
TPC36AHM3_A/I 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 standoff voltage of 30.8 V, breakdown voltage of 34.2–37.8 V at 1 mA, clamping voltage of 49.9 V at 30.1 A, and junction temperature rating up to +185 °C.
For engineers reviewing the TPC36AHM3_A/I datasheet, TPC36AHM3_A/I pinout, TPC36AHM3_A/I application, or TPC36AHM3_A/I equivalent, key selection criteria include unidirectional clamping performance under 10/1000 µs transients, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on high-density PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching spikes and ESD events. Its unidirectional architecture provides forward conduction capability while clamping reverse transients above VBR.
The device operates across -65 °C to +185 °C junction temperature range and maintains stable VBR with a temperature coefficient of +0.090 %/°C. It meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements for harsh-environment deployment.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | Lower PPPM (400 W), higher VC (53.3 V at 7.5 A), SMA package (higher thermal resistance) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Choose for cost-sensitive, non-automotive designs where 1500 W surge margin is not required |
| TPC33AHM3_A/I | Lower VWM (28.2 V), lower VC (45.7 V at 32.8 A), same package and AEC-Q101 qualification | Better suited for 24 V nominal systems requiring tighter clamping margin below 50 V | Choose when system VMAX is <30 V and lower clamping voltage improves downstream component safety margin |
Compared with SMAJ33A-E3/57T and TPC33AHM3_A/I, the TPC36AHM3_A/I delivers higher energy absorption (1500 W vs. 400 W or 1500 W), tighter VBR tolerance (±5 % vs. ±5 % or ±5 %), and guaranteed automotive qualification-making it optimal for 36 V nominal systems needing robust, production-ready surge immunity.

FAQ
What is the clamping voltage of the TPC36AHM3_A/I under standard 10/1000 µs surge conditions?
The TPC36AHM3_A/I has a maximum clamping voltage (VC) of 49.9 V at 30.1 A peak pulse current under 10/1000 µs waveform conditions. This value is measured per JEDEC-standard test methods and reflects worst-case voltage seen by downstream circuitry during transient events, ensuring safe operation for 36 V nominal systems.
Is the TPC36AHM3_A/I qualified for automotive applications?
Yes, the TPC36AHM3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C. It undergoes rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD-per automotive reliability standards, making it suitable for under-hood and ADAS applications where long-term stability is critical.
What does the "HM3_A/I" suffix indicate in TPC36AHM3_A/I?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance; "A" is the revision code; "I" specifies packaging in 13-inch tape-and-reel format with 6500 units per reel. This full suffix confirms compliance with automotive material requirements and logistics specifications for high-volume SMT assembly.
How does the dual-cathode configuration of the TPC36AHM3_A/I improve circuit protection?
The dual-cathode (pins 1 and 2) configuration in the TPC36AHM3_A/I allows symmetrical PCB layout with minimized loop inductance between protected line and ground return. This reduces voltage overshoot during fast-rising transients and enhances clamping effectiveness-especially critical in high-di/dt environments like motor drives and automotive power distribution.
Can the TPC36AHM3_A/I replace older TO-220 or DO-214AB TVS devices in existing designs?
The TPC36AHM3_A/I is not a direct drop-in replacement for TO-220 or DO-214AB packages due to its SMPC (TO-277A) footprint and 3-terminal layout. While electrical parameters align with many legacy 36 V TVS parts, PCB redesign is required to accommodate the smaller, low-profile SMPC pad pattern and dual-cathode routing-ensuring mechanical and thermal compatibility.
