Vishay Bi-Directional TVS Diode 3 kW Peak Pulse Power Surface Mount DO-214AB Package SMC3K12CAHM3_A/H

Vishay SMC3K12CAHM3_A/H Bi-Directional TVS Diode is a high-performance transient voltage suppressor designed for protection against voltage transients induced by inductive load switching, lightning, and electrostatic discharges in sensitive electronic circuits. Its 3 kW peak pulse power capability combined with a fast response time makes it ideal for robust safeguarding of ICs, MOSFETs, signal lines, sensor units, and other components used in consumer electronics, industrial equipment, automotive systems, telecommunications, and computer applications.

This diode features bi-directional transient voltage suppression within a compact DO-214AB surface mount package size (SMC3K series), easing integration into automated PCB manufacturing processes. It delivers a minimum breakdown voltage of 13.3 V and a maximum working stand-off voltage of 12 V, with a clamping voltage of 19.9 V to limit voltage spikes effectively. The device withstands peak pulse currents of up to 151 A and is specified for continuous operation between -55°C and 150°C, providing reliable performance in harsh environments.

The product complies with RoHS environmental standards and meets the automotive-grade AEC-Q101 qualification, ensuring high quality and reliability for automotive and industrial applications. Its small footprint (7.11 mm length, 2.62 mm width, 6.22 mm height) supports high-density PCB layouts while maintaining excellent surge resistance and electrostatic discharge protection with minimal leakage current (1 μA).

Typical applications include transient voltage protection for ICs, MOSFETs, sensor signal lines, automotive electronics, industrial controls, telecom equipment, and computers. The diode efficiently mitigates damaging voltage spikes to extend equipment lifespan and ensure system stability.
