Yageo — SMAJ-AT TVS Diodes

Yageo supplies a broad portfolio of transient voltage suppression (TVS) diodes which offer a very fast response to voltage transients induced by lightning and other events.

TVS diodes are used for the protection of sensitive circuitry because of their low dynamic resistance, excellent clamping capability, and high reliability. The portfolio of TVS diodes from Yageo includes industrial-grade and AEC-Q101-qualified automotive-grade parts in various package styles and power ratings for use in low-speed data transmission lines or dc power lines.

The working voltage of the Yageo TVS diodes ranges from 5 V to 600 V. The peak pulse power rating can reach up to 30 kW.

In automotive systems, there is strong demand for TVS diodes to protect the dc power input port of the 24 V power distribution bus. Yageo TVS diodes can suppress interference caused by unexpected load dumps immediately due to their ultra-fast response and high breakdown voltage.

In industrial systems, Yageo TVS diodes are widely used to protect RS-485 communications lines, which are often routed outdoors and exposed to lightning strikes. The fast response and low clamping voltage of the Yageo products provides excellent protection while avoiding interference with communications signals.
