Product details
Overview
TPC36AHM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for clamping inductive switching transients and lightning-induced surges on power rails and signal lines. It features a standoff voltage of 30.8 V, breakdown voltage range of 34.2–37.8 V at 1 mA, clamping voltage of 49.9 V at 30.1 A, and operates from −65 °C to +185 °C.
For engineers reviewing the TPC36AHM3/86A datasheet, TPC36AHM3/86A pinout, TPC36AHM3/86A application, or TPC36AHM3/86A equivalent, this device is selected for high-reliability automotive and industrial power-line protection where AEC-Q101 qualification, low-profile mounting, and sub-1.1 mm height are critical design constraints.
Technical Context
The TPC36AHM3/86A employs passivated anisotropic rectifier technology optimized for junction stability under repetitive surge stress. Its unidirectional architecture enables integration into DC power rails without reverse-bias leakage concerns, with clamping performance validated per ANSI/IEEE C62.35 using 10/1000 μs waveforms.
Thermal capability is defined by a maximum junction temperature of 185 °C and transient thermal impedance curves confirming effective heat dissipation on standard 2 oz copper PCBs. The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing on matte tin-plated leads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | Lower PPPM (400 W), higher VWM (33 V), SMA package (2.5 mm height) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 | Select only for cost-sensitive consumer applications with <500 W surge requirements |
| TPC33AHM3/86A | Lower VWM (28.2 V), lower VC (45.7 V at 32.8 A), same TO-277A package and AEC-Q101 grade | Better suited for 24 V systems requiring tighter clamping margin below 40 V | Preferred when protecting 3.3 V or 5 V logic rails downstream of buck converters with 28 V input |
Compared with SMAJ33A-E3/57T and TPC33AHM3/86A, the TPC36AHM3/86A delivers higher surge handling (1500 W vs. 400 W or matched 1500 W), tighter VWM–VBR alignment for predictable turn-on, and superior thermal robustness-making it optimal for 24–32 V automotive and industrial power rail protection where sustained reliability is mandatory.

FAQ
What is the maximum clamping voltage of the TPC36AHM3/86A under standard test conditions?
The TPC36AHM3/86A has a maximum clamping voltage (VC) of 49.9 V when subjected to a 10/1000 μs surge current pulse of 30.1 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during transient events. The TPC36AHM3/86A maintains this clamping performance across its full operating temperature range.
Is the TPC36AHM3/86A suitable for automotive applications?
Yes, the TPC36AHM3/86A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain-related automotive applications. Its TO-277A package, halogen-free construction, and MSL Level 1 rating further support compliance with automotive manufacturing and reliability requirements. The TPC36AHM3/86A is explicitly listed in Vishay's automotive-grade TVS portfolio.
What does the "HM3/86A" suffix indicate in TPC36AHM3/86A?
The "HM3" denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance. The "86A" specifies the preferred packaging: 7-inch plastic tape-and-reel with 1500 units per reel. This ordering code ensures traceable, production-ready delivery aligned with SMT assembly standards.
How does the dual-cathode configuration of the TPC36AHM3/86A improve performance?
The dual-cathode (Pins 1 and 3) configuration in the TPC36AHM3/86A provides symmetrical current distribution and enhanced thermal spreading across the TO-277A package footprint. This reduces localized heating during high-current surges and improves solder joint reliability under thermal cycling. Both cathodes are internally shorted, allowing flexible PCB layout with either or both pads used for grounding.
What is the standoff voltage (VWM) of the TPC36AHM3/86A, and why is it important?
The TPC36AHM3/86A has a standoff voltage (VWM) of 30.8 V - the maximum continuous DC or RMS voltage at which leakage remains ≤1 μA. This parameter ensures the device remains non-conductive during normal operation while providing sufficient margin below the 34.2–37.8 V breakdown threshold. Selecting a VWM closely matched to system nominal voltage (e.g., 24 V or 28 V rails) prevents false triggering and optimizes clamping headroom.
