Product details

AEC-Q101 TVS with 1.5 kW pulse handling — now obsolete

The 1.5KE75HE3/73: It clamps at 109 V maximum with a 60.7 V reverse standoff and 67.5 V minimum breakdown voltage, delivering 13.9 A peak pulse current per the standard 10/1000 µs test condition.

1.5 kW clamp in an axial DO-201AA body

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE75HE3/73 handles the full 1500 W peak pulse without secondary heatsinking — the lead frame and body dissipate the transient energy. The single unidirectional channel suits DC-rail and signal-line clamping where polarity is fixed.
