Peak pulse power is rated at 1500 W (1.5 kW) for the 10/1000 µs pulse — this sets the energy-handling ceiling for a single transient event. ## DO-214AB footprint and board integration Surface-mount with a standard JEDEC footprint — the cathode band is marked on the body for orientation. The tape-and-reel packaging supports automated pick-and-place for volume assembly.","metaTitle":"1.5SMC440C Littelfuse Zener TVS, 1500W Bidirectional","metaDescription":"Littelfuse 1.5SMC440C Zener TVS diode, 1500W peak pulse, 376V reverse standoff, DO-214AB.

For a functional replacement, evaluate other 1500 W bidirectional Zener TVS diodes in the DO-214AB package with a similar reverse standoff voltage (376 V) — but a board-level qualification is required since the breakdown and clamping voltages vary by device."},{"question":"How can I order 1.5SMC440C or check availability?","answer":"This obsolete part is sourced through independent distribution.
