Product details

Obsolete — last-time-buy window closed

The 1.5KE400-7003E3/54: For a BOM line that still needs this exact clamp voltage and package, sourcing is limited to what the spot market holds.

AEC-Q101 TransZorb — 1500 W peak pulse, 574 V clamp

Reverse standoff is 324 V; breakdown triggers at 360 V minimum. Clamping maxes at 574 V at 2.6 A peak pulse current — the part absorbs the surge before the downstream silicon sees overvoltage.

DO-201AA axial — through-hole board fit

Supplied in DO-201AA (DO-27) axial-lead package, through-hole mount. The 1.5KE body is the standard footprint for this power class — lead spacing and hole diameter match the common PCB layout used across the 1.5KE family. Tape-and-reel packaging suits automated insertion for high-volume assembly, though the obsolete status means reel quantities are lot-dependent.
