Product details
Overview
TPC22AHM3/86A 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 surge protection. It features a breakdown voltage of 20.9–23.1 V at 1 mA, clamping voltage of 30.6 V at 49.0 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC22AHM3/86A datasheet, TPC22AHM3/86A pinout, TPC22AHM3/86A application, or TPC22AHM3/86A equivalent, key selection criteria include unidirectional clamping performance, AEC-Q101 qualification, low-profile 1.1 mm height, and compatibility with automated SMT placement on power rails and sensor signal lines.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients. Its unidirectional architecture provides forward conduction capability while suppressing reverse polarity surges up to 1500 W (10/1000 µs waveform).
The device is rated for TJ = −65 °C to +185 °C, meets MSL Level 1 per J-STD-020, and is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive-grade reliability in harsh environments.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs against load-dump and jump-start transients in body control modules. IC Role / Device Role: Unidirectional TVS placed between VIN and GND to clamp surges above 18.8 V while passing normal operating voltage. Use Value: Limits clamped voltage to 30.6 V at 49 A, preventing damage to 3.3 V/5 V LDOs and MCU I/Os downstream. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop sensors) from ESD and inductive switching noise in factory automation PLCs. IC Role / Device Role: Low-capacitance unidirectional clamp on signal line to GND, leveraging fast <1 ns response to suppress nanosecond-scale transients. Use Value: Maintains signal integrity with minimal leakage (<1 µA at 18.8 V) and avoids false triggering during normal 24 V DC operation. |
| Automotive Lighting Driver Protection | Telecom DC Power Input Stage |
Use Scenario: Shielding LED driver ICs from back-EMF generated by relay-controlled headlamp circuits in ADAS lighting systems. IC Role / Device Role: High-energy (1500 W) unidirectional TVS mounted at driver input, absorbing 8.3 ms half-sine surges up to 200 A IFSM.

IC Role / Device Role: Primary unidirectional clamp on input rail before DC/DC converter, rated for 1500 W peak power per IEEE C62.35 standards. Use Value: Clamps 48 V nominal rail to ≤30.6 V during surge, preserving upstream fuse coordination and avoiding converter overvoltage shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 35.5 V @ 11.3 A | Not AEC-Q101 qualified; limited to commercial/industrial use; unsuitable for under-hood automotive | Select when cost sensitivity outweighs surge energy requirement and automotive qualification is unnecessary. |
| TPC22AHE3/86A | Same electrical specs, identical SMPC package, but HM3/86A suffix denotes halogen-free, RoHS, and AEC-Q101 - HE3/86A is obsolete revision | No functional difference; HE3/86A lacks latest material compliance documentation and may be discontinued | Prefer TPC22AHM3/86A for new designs requiring full Vishay material compliance and lifecycle support. |

FAQ
What is the clamping voltage of TPC22AHM3/86A at its rated peak pulse current?
The TPC22AHM3/86A has a maximum clamping voltage (VC) of 30.6 V when subjected to its specified peak pulse current (IPPM) of 49.0 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage during surge events. The TPC22AHM3/86A maintains this clamping performance across its full operating temperature range.
Is TPC22AHM3/86A qualified for automotive applications?
Yes, TPC22AHM3/86A is fully AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress testing (UHAST). Its 185 °C maximum junction temperature and halogen-free, RoHS-compliant construction meet automotive electronics requirements per Vishay document #99912.
What does the 'HM3/86A' suffix indicate in TPC22AHM3/86A?
The 'HM3/86A' suffix identifies the packaging and compliance version: HM3 denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction in SMPC (TO-277A) package; '/86A' specifies the tape-and-reel delivery mode (7" reel, 1500 pcs) with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance.
How does the dual-cathode configuration of TPC22AHM3/86A improve performance?
The dual-cathode (Pins 1 and 2) configuration in TPC22AHM3/86A lowers effective incremental surge resistance by enabling parallel current sharing during transient events. This design reduces localized heating and improves clamping consistency at high IPPM, directly supporting its 1500 W peak power rating and enhancing reliability under repetitive surge conditions.
Can TPC22AHM3/86A replace older TPC22A variants like TPC22AHE3/86A?
TPC22AHM3/86A is the designated replacement for TPC22AHE3/86A, offering identical electrical specifications and mechanical form factor. However, HM3/86A adds updated halogen-free and RoHS compliance documentation, full AEC-Q101 revalidation, and improved traceability - making it the recommended choice for new designs and production ramp.
