Product details
Overview
TPSMC12AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 16.7 V maximum clamping voltage at 89.8 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMC12AHE3_A/I datasheet, TPSMC12AHE3_A/I pinout, TPSMC12AHE3_A/I application, or TPSMC12AHE3_A/I equivalent, this page delivers verified electrical parameters, thermal limits (TJ = –65 °C to +185 °C), packaging details (DO-214AB), and real-world protection scenarios - including MOSFET gate driver rail clamping and sensor line surge suppression in harsh environments.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional polarity enables forward-biased conduction during overvoltage events while maintaining low leakage (<2 µA at 10.2 V, 25 °C) and fast response time under transient conditions.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 3.5 V maximum forward voltage at 100 A, and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its 185 °C maximum junction temperature supports under-hood automotive deployment without derating penalties.
