40V rail clamp with 64.5V ceiling
The SMBJ40CA-13-F: Its reverse standoff voltage is 40V, meaning the device does not conduct leakage current below that level during normal operation.
DO-214AA SMB package and temperature range
The bidirectional configuration uses a single die to clamp both positive and negative transients, saving board space compared to back-to-back unidirectional diodes.
Diodes Incorporated lists the SMBJ40CA-13-F as Active in production.
