Product details
Overview
TPC36HM3/87A 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 32.4 V to 39.6 V breakdown voltage (VBR), 29.1 V stand-off voltage (VWM), 52.0 V maximum clamping voltage (VC) at 28.8 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPC36HM3/87A datasheet, TPC36HM3/87A pinout, TPC36HM3/87A application, or TPC36HM3/87A equivalent, this device is selected for high-energy surge protection where low-profile mounting, 185 °C junction capability, and MSL Level 1 moisture sensitivity are critical - especially in automotive powertrain control units, industrial motor drives, and telecom DC input stages.
Technical Context
The TPC36HM3/87A employs passivated anisotropic rectifier technology optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional architecture provides forward conduction only, enabling integration into DC-biased circuits without reverse leakage concerns at operating voltages up to 29.1 V.
Rated for 1500 W peak pulse power (10/1000 µs waveform), it delivers 28.8 A IPPM with 52.0 V clamping at TJ = 25 °C and maintains derated performance up to 185 °C junction temperature. The TO-277A package supports automated placement and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V - ensures reliable triggering above normal 24 V rail fluctuations while avoiding false clamping |
| VWM | 29.1 V - maximum continuous reverse voltage before significant leakage; compatible with 24 V nominal systems |
| VC @ IPPM | 52.0 V - clamping voltage at 28.8 A pulse; limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events |
| PPPM | 1500 W - handles high-energy transients common in automotive load-dump and inductive kickback scenarios |
| TJ max. | +185 °C - enables under-hood deployment without thermal derating in engine control modules |
| Package | TO-277A (SMPC) - 3-pin surface-mount package with 1.1 mm profile, optimized for space-constrained PCB layouts |
| AEC-Q101 | Qualified - certified for automotive electronic systems per stress test requirements including HTOL, TC, and HAST |
Pinout & Package
TO-277A (SMPC) is a 3-terminal surface-mount package with cathode-anode-cathode configuration. Its low-profile design (1.1 mm typical height) and matte tin-plated leads support J-STD-002 solderability and JESD22-B102 reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-biased terminal | Connected to protected line; conducts when voltage exceeds VBR, shunting surge to ground |
| 2 (Anode) | Reference/ground terminal | Typically tied to system ground or low-impedance return path; completes clamping loop during transient |
| 3 (Cathode) | Reverse-biased terminal | Electrically identical to Pin 1; enables dual-cathode layout for symmetric PCB routing and reduced inductance |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier structure reduces leakage drift over temperature and lifetime |
| Low profile (1.1 mm) | Enables placement beneath connectors or near heat sinks without mechanical interference |
| MSL Level 1 | Zero floor life limitation - no baking required prior to reflow, simplifying SMT assembly |
| Halogen-free & RoHS | Complies with environmental regulations without compromising surge robustness or thermal performance |
| Automated placement ready | Matte tin terminations and defined land pattern ensure high-yield pick-and-place and reflow process control |

FAQ
What is the clamping voltage of the TPC36HM3/87A at its rated peak pulse current?
The TPC36HM3/87A has a maximum clamping voltage (VC) of 52.0 V at its rated peak pulse current (IPPM) of 28.8 A, measured using a 10/1000 µs waveform at TA = 25 °C. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream components remain within safe operating voltage ranges.
Is the TPC36HM3/87A suitable for automotive applications?
Yes, the TPC36HM3/87A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for automotive applications including engine control units, body control modules, and ADAS camera power supplies. Its TO-277A package and halogen-free construction further align with automotive manufacturing and compliance requirements.
What does the "HM3/87A" suffix indicate in TPC36HM3/87A?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. The "/87A" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 6500 units - a standard logistics format for high-volume SMT production.
How does the dual-cathode configuration of the TPC36HM3/87A improve circuit protection?
The TPC36HM3/87A uses a TO-277A package with two cathode terminals (Pins 1 and 3) and one anode (Pin 2), allowing symmetrical PCB layout that minimizes parasitic inductance in the clamping path. This configuration reduces voltage overshoot during fast transients and improves energy dissipation consistency compared to single-cathode alternatives.
What is the maximum reverse leakage current of the TPC36HM3/87A at its stand-off voltage?
At its stand-off voltage (VWM) of 29.1 V and ambient temperature of 25 °C, the TPC36HM3/87A exhibits a maximum reverse leakage current (IR) of 1.0 µA. At elevated junction temperature (TJ = 150 °C), leakage increases to 15 µA - a value still well within acceptable limits for most 24 V system monitoring and control circuits.
