The reverse standoff voltage is 18.8V, meaning the diode stays transparent on a nominal 12V or 15V rail and only starts conducting when the transient exceeds 20.9V breakdown (minimum). For a 24V bus, this part is too low — you would want the 1.5KE24A variant instead. ## Package and mounting — through-hole axial Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE22A-HF is a through-hole device. The DO-201 footprint is standard for 1500W TVS diodes — the large body and thick leads handle the thermal pulse without lifting pads. No power line protection (it is a unidirectional Zener, not a bidirectional or steering array).","metaTitle":"Comchip 1.5KE22A-HF Zener TVS, 1500W, DO-201","metaDescription":"Comchip 1.5KE22A-HF Zener TVS diode, 1500W peak pulse, 18.8V standoff, 30.6V clamp, DO-201 axial.
