Technical Details & Description

Clamping window for a 40.2 V rail

The 1.5KE47A/B: The 1500 W rating is the product of clamping voltage and peak current, so the actual surge energy capability scales with the pulse duration per the datasheet derating curve.

Through-hole DO-201 package — board integration

Housed in a DO-201AA / DO-27 axial package (supplier device package DO-201), this is a through-hole component intended for wave-solder or hand-solder assembly. The axial leads allow point-to-point wiring or PCB mounting with the body standing off the board. The package is unidirectional — one channel per device, with the cathode band indicating the polarity for DC rail protection. It is not rated for power line protection (AC mains continuous overvoltage), so it is suited for DC bus, signal line, or low-voltage AC secondary-side clamping.
