When a surge exceeds the breakdown threshold, the Zener junction avalanches and holds the voltage to 760 V, protecting downstream semiconductors rated for that transient ceiling. ## DO-201 axial leaded — board-level integration Housed in the DO-201AA (DO-27) axial leaded package, the 1.5KE550CA/B mounts through-hole with the body standing off the board. The DO-201 footprint is standard for 1.5 kW TVS diodes — the lead diameter and body length handle the thermal pulse energy without exceeding the junction temperature limit of -55°C to +150°C. The bidirectional configuration means a single device protects both polarities — useful for AC-coupled signal lines or DC rails where the transient can swing positive or negative relative to ground. No polarity marking needed on the PCB silkscreen; the part clips symmetrically. ## Active production — sourcing posture YAGEO lists the 1.5KE550CA/B as Active in production. The 1.5KE series is a broad, long-running TVS family. The base product number 1.5KE covers the full voltage range from 6.8 V to 550 V in both unidirectional and bidirectional variants, so the supply chain is well established.","metaTitle":"YAGEO 1.5KE550CA/B TVS Diode, 1500W, 467V Standoff, DO-201","metaDescription":"YAGEO 1.5KE550CA/B bidirectional Zener TVS, 1500W peak pulse power, 467V standoff, 760V clamping.
