The single bidirectional channel means the device protects against both positive and negative transients in a single package, simplifying board layout for AC or bipolar DC lines. ## Package and thermal envelope Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE550C is a through-hole component suited for point-of-use transient suppression on power rails or signal lines where board space allows leaded mounting. The operating junction temperature range spans -55°C to 175°C, covering industrial and automotive under-hood thermal environments without derating concerns. No power line protection is specified, so this part is intended for secondary-level transient suppression rather than primary AC mains clamping. Available through independent surplus and broker channels, this part is sourced per RFQ. Date-code spread and packaging condition (sealed reel vs. cut tape) are confirmed at quote time.","metaTitle":"Littelfuse 1.5KE550C TVS Diode, 1500W, 495V, DO-201","metaDescription":"Obsolete Littelfuse 1.5KE550C bidirectional Zener TVS diode, 1500W peak pulse, 495V breakdown, DO-201 axial.
