160V rail protection — clamp voltage and standoff threshold
The SMBJ160A-13: Its reverse standoff voltage is 160 V, breakdown occurs at a minimum of 178 V, and the clamping voltage at peak pulse current is 259 V — this defines the maximum voltage the downstream circuitry sees during a surge event. This energy rating determines how large a transient the diode can shunt without failing — useful for protecting DC power buses, I/O lines, and telecom interfaces on a 160 V rail.
Package and board integration — DO-214AA SMB
Power line protection is not built in — this is a unidirectional device for DC or signal-line clamping, not AC mains.
Supplied in Cut Tape (CT) packaging, it is suited for prototype builds and low-to-mid volume assembly. For higher volumes, reel packaging may be available — confirm at quote.
