The SMAJ58A with TVS SMA (DO-214AC) RoHS is an electronic component manufactured by Bourne. It is a surface-mount Transient Voltage Suppressor (TVS) Diode that conforms with the two-pin discrete semiconductor packaged in a SMA style with the DO-214AC form factor. It is RoHS Compliant, which means it has been tested to be free of lead, mercury, cadmium, hexavalent chromium, and other restricted substances. This component is designed to protect sensitive circuitry from voltage or current transients caused by lightning, electrostatic discharge, and AC line transients. It is rated for a peak pulse power of 600W and rated for a breakdown voltage of 58V.
