Rated for continuous operation from -55°C to +150°C junction temperature, the 1.5KE480CA/B fits into outdoor telecom enclosures, industrial motor drives, and automotive under-hood environments where ambient heat and self-heating from repetitive surges must coexist. The through-hole DO-201 axial package (also listed as DO-27) allows the body to be soldered into a PCB or wired point-to-point in a terminal block — the large copper tab on the cathode side sinks heat into the board copper. No power line protection rating is claimed — this device is intended for secondary-side signal or DC rail clamping, not mains AC primary protection.
