Breakdown occurs at a minimum of 48.5V, so the device stays transparent during normal 48V bus operation and only clamps when a surge pushes the line above that threshold. ## Package and thermal integration Housed in a DO-201AA (DO-27) axial-lead package with a DO-201 supplier device package designation, this through-hole part suits point-to-point wiring or PCB mounting with lead bending. The junction temperature range spans -55°C to 175°C, covering most industrial and telecom enclosures without derating concerns. Power line protection is not provided — this is a general-purpose transient suppressor for signal or low-power DC rails, not for AC mains or high-energy power bus clamping. ## Sourcing and lifecycle status Supplied in Tape & Reel packaging, this suits automated insertion for volume builds.","metaTitle":"1.5KE51A R0G TVS Zener Diode, 1500W, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE51A R0G Zener TVS diode, 1500W peak pulse, 70.1V clamping, DO-201 axial.
