At the rated 19.7A peak pulse current, the clamp holds at 77V — this is the voltage the downstream components must survive. The single bidirectional channel protects against both positive and negative transients in one package, saving board space compared to back-to-back unidirectional diodes. ## Package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE56CA/B is a through-hole part suited for point-of-use transient suppression on power input stages or relay coils. The junction temperature range spans -55°C to 150°C, covering most industrial and outdoor deployment envelopes. YAGEO lists the 1.5KE56CA/B as Active in production.","metaTitle":"YAGEO 1.5KE56CA/B TVS Diode, 1500W, 77V Clamp, DO-201","metaDescription":"YAGEO 1.5KE56CA/B bidirectional Zener TVS, 1500W peak pulse, 47.8V standoff, 77V clamp.
