When the incoming spike exceeds the 22.8 V minimum breakdown voltage, the device clamps at 33.2 V max, passing up to 45.8 A of the 10/1000 µs surge waveform before the silicon recovers. The 20.5 V reverse standoff means this part sits across a 20 V or 24 V supply bus without conducting in normal operation — it stays dark until the transient arrives. ## Package and rework — DO-214AB (SMC) under the iron Housed in the DO-214AB (SMCJ) surface-mount package, the 1.5SMC24A measures roughly 7.1 mm × 6.2 mm with a 2.6 mm seated height — a medium-footprint TVS that takes standard reflow profiles. The cathode band is clearly marked on the body; orientation is unambiguous for hand placement or pick-and-place. ## Active lifecycle — no LTB clock ticking No stock-holding claim — quoted per RFQ.","metaTitle":"Littelfuse 1.5SMC24A TVS Diode, 1500W, 20.5V Standoff","metaDescription":"Littelfuse 1.5SMC24A Zener TVS diode, 1500W peak pulse power, 20.5V reverse standoff, 33.2V clamp, DO-214AB SMC.
