The 1500W peak pulse power rating means it can absorb a single surge of that energy without failing — useful for suppressing inductive load dumps or lightning-induced transients in automotive and telecom equipment. ## Automotive and telecom deployment The same wide temperature margin suits outdoor telecom cabinets that see direct sun and winter freeze. The copper tab on the bottom side should be soldered to a thermal pad on the PCB — the junction-to-ambient thermal resistance drops significantly with a flooded copper plane under the package. Tape-and-reel packaging suits automated pick-and-place for volume production. ## Active lifecycle — sourcing posture No direct pin-compatible second-source is recorded, but the 1.5SMC family shares the same DO-214AB footprint across voltage variants, so a different standoff voltage could be substituted with a BOM update if the circuit allows.","metaTitle":"Vishay 1.5SMC47CAHM3_A/I TVS Diode, 64.8V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC47CAHM3_A/I bidirectional TVS, 40.2V standoff, 64.8V clamp at 23.1A.
