For existing designs that still need this exact clamping voltage and package, the only channel is independent surplus or broker inventory — sourced per RFQ, lot-specific, with no guarantee of continuous supply. ## What the 1500 W rating buys you Clamps at 80.85 V maximum when hit with a 19.7 A peak pulse current. The 47.8 V reverse standoff means the protected rail should stay below that voltage during normal operation; the diode starts conducting around 50.4 V breakdown. Bidirectional single-channel configuration — one device protects both polarities, useful on AC signal lines or DC rails where reverse-voltage events are possible. ## Package and board-fit for the pick-and-place line Standard JEDEC outline, no exotic pad geometry. Supplied on Tape & Reel (TR), so it feeds directly into a standard pick-and-place feeder without a reel change.","metaTitle":"Littelfuse 1.5SMC56C TVS Diode, 1500W, 47.8V Standoff","metaDescription":"Obsolete Littelfuse 1.5SMC56C bidirectional TVS diode, 1500W peak pulse, 47.8V standoff, DO-214AB.
