High current TVS diode protects electronic systems from surges

Mouser now stocks the Bourns PTVS1-240C-M high-current TVS diode. This bidirectional diode protects electrical systems from high-voltage transients and ESD. It was developed for high-power DC bus protection and clamping applications and is ideal for industrial power systems, energy storage systems, and factory automation.

The device is one of the industry's first bidirectional power TVS diodes in a space-saving surface mount package. The diode produces a maximum breakdown voltage of 295V, a repetitive standoff voltage of 240V, and a precise clamping voltage of 340V. The series protects against ESD and high current surges, with a 1kA surge handling capability under 8/20μs test conditions. With a stable voltage breakdown sensitivity over temperature of 0.1% per C, engineers can accurately predict how the diode will behave in different environments.

The low-leakage TVS diode consumes just 10µA when on standby. Housed in a compact surface-mountable package, it lowers the PCB footprint compared with conventional through-hole-mounted power TVS diodes. It is UL497B certified, meets IEC 61000-4-5 standard specifications, and is RoHS compliant
