The unidirectional configuration (one channel) is polarity-sensitive; use it where the protected line is always positive with respect to ground. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE440A/B is a through-hole part that solders into a 0.036-inch (0.9 mm) diameter hole on a standard PCB or terminal block. The DO-201 package body is glass-passivated for high-temperature stability and moisture resistance — store the reels dry, but the hermetic seal means no special bake-out before assembly. The wide temperature range ensures the clamping voltage stays within spec across the full ambient range of an outdoor enclosure or engine bay. Sourced through authorized and independent distribution channels. No stock-holding claim; quoted to order per RFQ.","metaTitle":"YAGEO 1.5KE440A/B TVS Diode, 1.5kW, 376V Standoff","metaDescription":"YAGEO 1.5KE440A/B Zener TVS diode, 1500W peak pulse power, 376V reverse standoff, 602V clamping, DO-201 package.
