Packaged in the DO-201AA / DO-27 axial-lead form factor, it mounts through-hole on a board or terminal strip — the axial body handles the thermal pulse of a 1500 W surge without requiring a heatsink. ## Bidirectional clamping for AC or floating DC rails With a single bidirectional channel, this TVS clamps transients of either polarity — suitable for AC signal lines, floating DC buses, or any application where the surge polarity is unknown. No power line protection feature is built in — this is a standalone transient suppressor, not a filtered or coordinated protector; it relies on the upstream fuse or breaker for overcurrent clearing. ## Obsolete — sourced through independent channels No official successor part number is recorded from Vishay for this order code.","metaTitle":"Vishay 1.5KE440C-E3/73 TransZorb TVS, 1500W Bidirectional","metaDescription":"Vishay 1.5KE440C-E3/73 TransZorb bidirectional TVS diode, 1500W peak pulse, 356V standoff, 631V clamp.
