Transient voltage suppressor for 33.3V rails
The 1.5SMC39AS_R1_00001: Its 33.3V reverse standoff voltage protects 24V or 33V DC buses from transients that exceed normal operating levels.
Clamping window and current handling
Breakdown occurs at 37.1V minimum, clamping the surge at 53.9V maximum while conducting 28A peak pulse current. This window keeps the protected rail below the abs-max rating of downstream 40V-rated components during a surge event.
Package and temperature range
The SMC footprint is standard for 1500W-class TVS diodes, allowing drop-in replacement across suppliers.
