Transient protection for a 85.5 V rail
It delivers 1500 W of peak pulse power per the 10/1000 µs waveform, with a minimum breakdown voltage of 95 V and a maximum clamping voltage of 178 V at the rated peak pulse current of 56 A. The DO-214AB SMC package suits surface-mount assembly for general-purpose overvoltage protection in industrial, telecom, and automotive auxiliary circuits.
1500 W peak pulse — sizing the protection margin
The 1500 W rating (10/1000 µs) defines the energy the diode can absorb in a single pulse. For a 85.5 V rail, the 178 V clamping ceiling leaves headroom above the rail plus any normal ripple, so the protected downstream components see a hard voltage limit.
Temperature range and board-level fit
The SMC package footprint is standard for this power class; the cathode band identifies the unidirectional orientation.
