Clamping voltage and the protection margin
The SMCJ8.0A-13: The reverse standoff voltage is 8V, meaning the diode remains transparent below that level. This 13.6V ceiling is the key number for the system designer: the protected rail must tolerate that voltage during the transient event, or a lower-voltage TVS is needed.
DO-214AB SMC package — board fit
Housed in the DO-214AB (SMC) surface-mount package, the device operates across -55°C to 150°C junction temperature. The SMC footprint is larger than the smaller SMA/SMB siblings, which translates to better heat dissipation from the die during repetitive surge events. The tape-and-reel packaging suits automated pick-and-place assembly.
