The clamping voltage of 30.6 V at 49.7 A peak pulse current defines the maximum voltage the protected circuitry sees during a surge event — a 30.6 V clamp on an 18.8 V rail absorbs a 62 % overvoltage before the TVS limits further rise. This is a single bidirectional channel — a single DO-201 axial package clamps both polarities, eliminating the need for two series diodes in AC or bipolar signal protection. ## DO-201 axial package and temperature range Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE22CA/B mounts through-hole on a PCB or terminal block. The junction operates from -55 °C to 150 °C, covering industrial and automotive under-hood ambient conditions without derating at the upper end. The part is not rated for power line protection — it targets signal and DC rail transient suppression where the 1500 W peak pulse capability handles ESD, inductive kickback, and surge events per IEC 61000-4-5.","metaTitle":"YAGEO 1.5KE22CA/B TVS Diode, 1500W, 30.6V Clamp","metaDescription":"YAGEO 1.5KE22CA/B bidirectional Zener TVS, 1500W peak pulse, 18.8V standoff, 30.6V clamp.
