The 1500 W rating means this part absorbs substantial surge energy without failing short — useful for protecting 24 VDC to 36 VDC rails on industrial control I/O, sensor power feeds, or telecom line cards where a single TVS shunts both positive and negative transients to ground. ## Package and mounting — DO-201 axial, through-hole Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the 1.5KE43CA/B is a through-hole part intended for wave-solder or hand-solder assembly. The axial body and 0.042-inch diameter leads fit standard 0.100-inch pitch PCB holes — a direct drop-in replacement for legacy 1.5KE family parts in the same footprint. ## Sourcing and lifecycle — active, no obsolescence concern No pin-compatible second-source is recorded in the YAGEO family, but the 1.5KE series is a widely cross-referenced industry standard footprint.","metaTitle":"YAGEO 1.5KE43CA/B TVS Diode, 1500W, 36.8V Standoff, DO-201","metaDescription":"YAGEO 1.5KE43CA/B bidirectional Zener TVS diode, 1500W peak pulse power, 36.8V reverse standoff, 59.3V clamping.
