The 207V clamp ceiling protects downstream semiconductors rated for 250V or less. ## DO-201 axial footprint and through-hole mounting Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the 1.5KE150A/B mounts through-hole on a PCB or terminal block. The axial leads handle the 1500W pulse without trace lift-off when the board layout keeps the lead length under 6 mm per side. No power line protection feature is asserted — this is a unidirectional clamp for DC rails, not an AC mains protector. The single unidirectional channel covers positive-polarity transients to ground. ## Active lifecycle and sourcing posture No official second-source or pin-compatible cross-reference is listed in the manufacturer data. The 1.5KE series covers multiple standoff voltages; a 1.5KE150A/B is the specific 128V standoff variant.","metaTitle":"YAGEO 1.5KE150A/B Zener TVS Diode, 1500W, DO-201","metaDescription":"YAGEO 1.5KE150A/B Zener TVS, 1500W peak pulse power, 128V standoff, 207V clamping.
