Product details
Overview
TPC11AHM3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for robust overvoltage protection of sensitive electronics. It features a breakdown voltage of 10.5 V to 11.6 V at 1 mA, clamps transients up to 15.6 V at 96.2 A peak pulse current, and operates across -65 °C to +185 °C junction temperature - ideal for automotive power line and sensor interface protection.
For engineers reviewing the TPC11AHM3_A/H datasheet, TPC11AHM3_A/H pinout, TPC11AHM3_A/H application, or TPC11AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 1500 W peak pulse power rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and uni-directional clamping behavior in high-reliability automotive and industrial systems.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable breakdown and low incremental surge resistance. Its unidirectional architecture provides forward conduction during overvoltage events while maintaining low leakage (<5 µA at 9.4 V) and fast response time under 1 ns.
The device is rated for 1500 W peak pulse power (10/1000 µs waveform), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and delivers clamping voltage of 15.6 V at 96.2 A - enabling effective protection of MOSFETs, ICs, and signal lines against inductive switching transients and ESD-like surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1 mA - defines precise turn-on threshold for reliable overvoltage triggering |
| VWM | 9.4 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA |
| VC @ IPPM | 15.6 V at 96.2 A - clamping voltage limiting downstream component stress during surge |
| PPPM | 1500 W (10/1000 µs) - peak transient energy absorption capability for automotive load dump immunity |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| Polarity | Uni-directional - protects against positive-going transients only; requires correct orientation in circuit |
| Package | TO-277A (SMPC) - surface-mount, low-profile (1.1 mm height), AEC-Q101 qualified, MSL Level 1 |
Pinout & Package
TO-277A (SMPC) package: 3-terminal surface-mount device with cathode-anode-cathode configuration. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards; HM3 suffix indicates halogen-free, RoHS-compliant, and JESD 201 Class 2 whisker-tested construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt current to ground |
| Terminal 2 | Anode | Common reference node (typically system ground); completes clamping path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 18.2 V at 21.6 A | Not AEC-Q101 qualified; suitable for commercial-grade consumer products only | Select when cost sensitivity outweighs automotive reliability requirements and surge energy is below 400 W |
| TPC11AHE3_A/H | Same electrical specs but HE3 suffix denotes alternate tape/reel packaging (13" reel, 6500 pcs) | No functional difference; identical performance and qualification | Choose based on volume procurement needs and assembly line feed requirements |
Compared with SMAJ11A and TPC11AHE3_A/H, the TPC11AHM3_A/H offers superior surge handling (1500 W vs. 400 W), automotive qualification, and lower clamping voltage - making it the preferred choice for safety-critical vehicle subsystems where layout space allows TO-277A mounting.

FAQ
What is the breakdown voltage range for TPC11AHM3_A/H?
The TPC11AHM3_A/H has a specified breakdown voltage (VBR) range of 10.5 V to 11.6 V measured at 1 mA test current. This tight tolerance ensures consistent turn-on behavior across production lots and temperature ranges, critical for predictable clamping in automotive power systems where overvoltage thresholds must be precisely controlled to avoid nuisance tripping or insufficient protection.
Is TPC11AHM3_A/H AEC-Q101 qualified?
Yes, TPC11AHM3_A/H is fully AEC-Q101 qualified. The HM3 suffix explicitly denotes halogen-free, RoHS-compliant construction meeting the stress test requirements for automotive discrete semiconductors - including high-temperature reverse bias, temperature cycling, and mechanical shock. This qualification confirms suitability for under-hood and safety-critical vehicle applications where long-term reliability is mandatory.
What does the "HM3" suffix mean in TPC11AHM3_A/H?
The "HM3" suffix in TPC11AHM3_A/H identifies the packaging and compliance grade: "H" denotes the TO-277A (SMPC) package, "M3" specifies halogen-free, RoHS-compliant materials, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance. The trailing "_A/H" indicates revision A and tape-and-reel delivery in 7-inch reels (1500 pcs per reel), per Vishay's ordering nomenclature.
Can TPC11AHM3_A/H replace SMAJ11A in existing designs?
TPC11AHM3_A/H is not a direct drop-in replacement for SMAJ11A due to different package (TO-277A vs. SMA), higher power rating (1500 W vs. 400 W), and lower clamping voltage (15.6 V vs. 18.2 V). PCB layout changes are required for footprint and thermal pad adaptation. However, it can be used in upgraded designs where enhanced surge immunity and automotive qualification are needed.
What is the maximum operating junction temperature of TPC11AHM3_A/H?
The maximum operating junction temperature (TJ) of TPC11AHM3_A/H is +185 °C. This rating enables reliable operation in high-temperature automotive environments such as engine compartments or near power converters, without requiring derating up to this limit - unlike many commercial-grade TVS diodes limited to +150 °C or lower.
