Technical Details & Description

The 1.5SMBJ18CA: For a 24V automotive bus or a 12V rail with load-dump transients, the 18V reverse standoff sits below the nominal rail so the diode stays off until a spike exceeds 20V breakdown, then clamps at 29.2V max while shunting 51.4A peak pulse current.

AEC-Q101 automotive grade — deployment envelope

Qualified to AEC-Q101, this part is screened for the -55°C to 150°C junction temperature range — the full under-hood and chassis-domain temperature band. The DO-214AA (SMB) package is a common surface-mount footprint; the board layout matches the standard SMB land pattern used across the 1.5SMBJ series.

Active lifecycle — no obsolescence watch needed

Production status is Active — the 1.5SMBJ18CA is still in current manufacture and suitable for new designs.
