1500W peak pulse in a DO-214AA footprint
The 1.5SMBJ28CA: The 28V reverse standoff voltage means it sits across a 24V nominal rail without conducting leakage, clamping at 45.4V max when the pulse current hits 33.1A.
AEC-Q101 grade for under-hood and chassis duty
Qualified to AEC-Q101, this part carries the automotive-grade reliability screening — temperature cycling, high-temperature reverse bias, and preconditioning that a commercial-grade TVS does not see. The -55°C to 150°C junction range covers the under-hood ambient where the diode sees conducted transients from the alternator and load-dump events.
Active production — no last-time-buy pressure
Listed as Active by Bourns, so there is no EOL clock ticking on this part number.
