Product details

600W bidirectional TVS for 58V rails

The SMBJ58CA-13-F: Its 58V reverse standoff voltage (VRWM) means it sits across a 48V or 58V nominal rail without conducting in normal operation, then clamps transients at 93.6V maximum. The 64.4V minimum breakdown voltage ensures the device triggers before the clamping level is reached, providing a defined protection window. With a single bidirectional channel, it handles surges on AC or bipolar signal lines without needing two diodes back-to-back.

Package and thermal range

The 6.4A peak pulse current (IPP at 10/1000µs) combined with the 600W rating means the device can absorb substantial surge energy, but the actual clamping voltage at lower currents will be below the 93.6V maximum — useful for estimating protection margins on sensitive 5V or 3.3V downstream circuits when the TVS is used as a secondary clamp.

The base product number is SMBJ58, and the -13-F suffix indicates tape-and-reel packaging for automated assembly.
