180V reverse standoff and 600W surge rating
The SMBJ180A-13-F: Its 180V reverse standoff voltage means it stays transparent below that threshold, only conducting when the line exceeds 200V breakdown minimum. The 291.6V maximum clamping voltage at 2.06A peak pulse current (10/1000µs waveform) sets the protection ceiling — downstream components must survive that clamp voltage for the pulse duration. The 10/1000µs waveform is the standard TVS test pulse; a real-world transient with shorter duration allows higher peak current before the device reaches its thermal limit.
DO-214AA SMB package and temperature range
The junction temperature range spans -55°C to 150°C, covering industrial and outdoor equipment without derating at the cold end.
