Product details
Overview
SMCJ6.0AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping ESD and surge transients on power and signal lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 145.6 A peak surge current - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ6.0AHE3/9AT datasheet, SMCJ6.0AHE3/9AT pinout, SMCJ6.0AHE3/9AT application, or SMCJ6.0AHE3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (−55 to +150 °C), and polarity marking details for robust circuit protection design.
Technical Context
The SMCJ6.0AHE3/9AT operates as a unidirectional avalanche diode with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its low incremental surge resistance and fast clamping action protect downstream ICs during inductive switching events or lightning-induced surges.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets MSL level 1 (260 °C reflow peak) and supports automated placement. The cathode band marking identifies polarity, and its RoHS-compliant matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
