This clamping window — 380 V to 548 V — defines the voltage the downstream circuitry must survive during the event. The -55°C to 150°C junction temperature range covers industrial and outdoor equipment where the ambient sees wide thermal swings; the bidirectional configuration (single channel) protects signal pairs that swing above and below ground, such as RS-485 or isolated power rails. Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The axial leads handle the thermal cycling of the soldering process without stress on the die bond. ## Active production, sourced per RFQ YAGEO lists the 1.5KE400CA/B as an active product.","metaTitle":"YAGEO 1.5KE400CA/B TVS Diode, 1500W, Bidirectional","metaDescription":"YAGEO 1.5KE400CA/B Zener TVS diode, 1500W peak pulse power, 342V standoff, bidirectional, DO-201 package.
