The 1500 W rating at the standard 10/1000 µs test waveform is the headline surge capability; real-world energy handling depends on the actual pulse width and duty cycle. ## DO-201 axial package and temperature range Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), the 1.5KE11C-B mounts through-hole on the PCB. The operating junction temperature range spans -55°C to 175°C, covering the full industrial temperature envelope and allowing deployment in high-ambient environments such as motor-drive cabinets or outdoor telecom power supplies. A parametric search on standoff voltage (9.4 V) and package (DO-201) is the practical cross-reference path.","metaTitle":"1.5KE11C-B Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE11C-B Zener TVS diode, 1500W peak pulse power, 9.4V standoff, bidirectional, DO-201 axial.
