Bidirectional TVS offers high surge capability and lower leakage current

Vishay Intertechnology, Inc has a new series of surface-mount TRANSZORB bidirectional TVS in the SMC (DO-214AB) package for automotive, industrial, and telecom applications. Providing high surge capability of 3kW at 10/1000μs to meet the specifications of ISO 16750-2 Pulse b, the SMC3KxxxCAHM3_A series devices offer low leakage current down to 1μA from 22V to 120V and high-temperature operation to +175C.

Ideal for high-reliability applications, the series is AEC-Q101 qualified and provides extremely stable breakdown voltage from 11.1V to 133V across the entire operating temperature range of -55C to +175C. Created to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning, the devices are targeted at automotive load dump protection and signal line protection in industrial and telecom systems.

The series comprises 33 TVS part numbers with stand-off voltages from 10V to 120V. The devices provide fast response times, low incremental surge resistance, and excellent clamping capability, with a maximum clamping voltage from 17V to 193V at 10/1000μs. The devices are RoHS-compliant and halogen-free, and they provide an MSL of 1 in accordance with J-STD-020, LF maximum peak of 260C.
