It handles 2A peak pulse current (Ipp) under the standard 10/1000µs test condition. ## Through-hole fit and temperature range Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE540CA is a through-hole part — you solder it into a board or wire it into a terminal block. The DO-201 footprint is standard and well-documented; the axial leads make it a candidate for point-to-point wiring in power supplies or industrial controls where a surface-mount TVS might not handle the surge energy. No power line protection (the part is not designed for continuous AC mains clamping — it is a transient suppressor, not a line filter).","metaTitle":"Littelfuse 1.5KE540CA TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE540CA bidirectional TVS diode, 1500W peak pulse power, 460V standoff, 740V clamping.
