At the 71.7 A peak pulse current (Ipp), the clamping voltage holds at 21.2 V maximum. The reverse standoff voltage is 12.8 V, meaning the diode stays off below that rail voltage and only begins conducting when the transient exceeds the minimum breakdown of 14.3 V. For a 12 V nominal rail, this gives roughly 1.5 V of headroom before the diode starts to clamp. ## Package and board integration Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE15A/B is a through-hole part intended for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The DO-201 body is the standard footprint for 1500 W axial TVS diodes — the lead spacing and body diameter match the industry socket for this power class.","metaTitle":"YAGEO 1.5KE15A/B TVS Diode, 1500W, DO-201","metaDescription":"YAGEO 1.5KE15A/B unidirectional Zener TVS diode, 1500W peak pulse power, 12.8V standoff, DO-201 axial package.
