Bidirectional Transient Voltage Suppressors with Low Incremental Surge Resistance designed for Automotive, Industrial, and Telecom Applications

Vishay Intertechnology, Inc. has introduced a new series of surface-mount TRANSZORB bidirectional transient voltage suppressors (TVS) in the SMC (DO-214AB) package that offers a high surge capability of 3 kW at 10/1000 μs to meet the specifications of ISO 16750-2 Pulse b. Designed to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning, these devices are intended for automotive load dump protection and signal line protection in industrial and telecom systems. 

The new SMC3KxxxCAHM3_A series devices are AEC-Q101 qualified and offer extremely stable breakdown voltage from 11.1 V to 133 V across their entire operating temperature range of -55 °C to +175 °C. These devices offer very fast response times and low incremental surge resistance, and excellent clamping capability with a maximum clamping voltage from 17.0 V to 193 V at 10/1000 μs.
