Technical Details & Description

1500W Zener clamp for automotive and telecom bus protection

The 1.5SMC15H: AEC-Q101 qualification and the -55°C to 150°C junction temperature range make it suitable for under-hood electronics, engine control modules, and other automotive environments where the 12V bus sees load-dump and inductive transients.

Clamping voltage and pulse current — the real protection margin

The 13.5V minimum breakdown voltage ensures the device starts conducting before the protected rail exceeds the 12V nominal bus tolerance, while the 22V maximum clamping limits the voltage seen by downstream components during a 71A surge event.
