30V Rail Protection with 1.5kW Surge Margin
Its 33.3V minimum breakdown voltage ensures the device stays off during normal operation, while the 53.5V maximum clamping voltage at 28A peak pulse current (10/1000µs waveform) limits the voltage spike seen by the protected load.
The 30V reverse standoff voltage is the maximum continuous DC voltage the TVS can sit across without conducting leakage current — match this to your rail voltage, not the peak. The 33.3V minimum breakdown is the threshold where the device starts to avalanche; a rail that sags or overshoots near this value risks nuisance triggering. The 53.5V clamp at 28A is the worst-case voltage the load sees during a 10/1000µs surge — ensure downstream components have a voltage rating above this clamp level. The 1500W peak pulse power is the product of clamp voltage and peak current at the specified waveform; derate for higher ambient temperatures per the datasheet curve.
Package and Assembly: DO-214AB SMC on Tape & Reel
The DO-214AB footprint is a standard JEDEC outline for 1.5kW TVS diodes, with a large copper pad on the cathode side for heat sinking. The part is RoHS-compliant per Microchip's suffix — no lead or restricted substances in the termination finish.
