Transient protection for a 64V DC rail
Its 64V reverse standoff voltage means it sits across the rail without conducting during normal operation, only turning on when the line exceeds 71.1V minimum breakdown.
600W peak pulse power — what it buys you
Rated at 600W peak pulse power for an 10/1000µs exponential waveform, this device can absorb a single surge from a 64V supply line — think inductive load dump, lightning-induced spike on outdoor telecom gear, or a battery hot-swap transient. The 600W rating is the product of clamp voltage and peak current at the test waveform; real-world energy depends on the actual surge duration and impedance.
Package and mounting for the BOM
Housed in a DO-214AA (SMB) package, the SMBJ64CE3/TR13 is a surface-mount Zener TVS suited for automated assembly.
