The 77.8 V standoff means the protected rail can run at 48 V nominal or 60 V with margin, and the TVS stays in standby until a transient pushes above the breakdown threshold (86.5 V minimum). At 125 V clamping, downstream components rated for 150 V or higher see a safe voltage during a surge. ## Active production, sourced per RFQ Pricing and availability are confirmed at quote time against the BOM quantity. ## DO-201 axial package, -55 to 150 °C operating range Mounted through-hole in a DO-201AA (DO-27) axial package, the device suits point-to-point wiring on terminal strips or PCB through-hole layouts. The junction temperature range spans -55 °C to 150 °C, covering industrial and outdoor telecom enclosure environments. No power line protection — the device is intended for signal and low-voltage DC bus clamping, not AC mains.","metaTitle":"YAGEO 1.5KE91CA/B TVS Diode, 1500W, 77.8V Standoff","metaDescription":"YAGEO 1.5KE91CA/B bidirectional Zener TVS, 1500W peak pulse power, 77.8V reverse standoff, 125V clamping.
