Vishay Introduces TRANSZORB® TVS in SMC (DO-214AB) Package

Vishay Introduces TRANSZORB® TVS in SMC (DO-214AB) Package with High Surge Capability up to 3 kW and Leakage Current as Low as 1 μA

Bidirectional devices operate up to +175 °C and have stable breakdown voltages from 11.1 V to 133 V for automotive, industrial, and communications applications

MALVERN, Pennsylvania — June 1, 2022 — Vishay Intertechnology, Inc. recently announced the launch of a new series of surface-mount TRANSZORB® bidirectional transient voltage suppressors (TVS) in SMC (DO-214AB) packages --- SMC3KxxxCAHM3_A , which can be used in automotive, industrial and communications applications. The SMC3KxxxCAHM3_A series devices have a surge performance of up to 3 kW under 10/1000 μs conditions, meet ISO 16750-2 Pulse b specifications, have a leakage current as low as 1 μA from 22 V to 120 V, and operate at a temperature of +175 C.

The recently released Vishay General Semiconductor TVS has passed AEC-Q101 certification and provides a very stable breakdown voltage of 11.1 V to 133 V over the entire operating temperature range of -55 °C to +175 °C, suitable for a variety of high-reliability applications. The device can protect sensitive electronic equipment from voltage transient damage caused by inductive load switching and lighting. Typical applications include automotive load dump protection, industrial and communication system signal line protection.

The SMC3KxxxCAHM3_A series has 33 TVS devices with reverse working voltages from 10 V to 120 V. The device has very fast response speed and low incremental surge resistance, and excellent clamping performance with a maximum clamping voltage of 17.0 V to 193 V under 10/1000 μs conditions. The device is RoHS-compliant, halogen-free, meets J-STD-020 moisture sensitivity (MSL) level 1, and has a maximum LF peak of 260 °C.

Samples and production quantities of the new SMC3KxxxCAHM3_A series are available now, with lead times of 12 weeks for larger orders.
