The 50 V minimum breakdown voltage gives the diode headroom above the standoff before it turns on, so the clamping action is deliberate and fast — not a soft clipping behaviour, but a hard avalanche trigger at the rated threshold. ## DO-214AB SMC — the standard TVS footprint for 1.5 kW class The SMC (DO-214AB) package is the dominant footprint for 1.5 kW TVS diodes across the industry — the cathode bar centres the thermal path to the board pad, and the anode-wide pad gives the solder joint a thermal escape route during clamping events. Solder-mask defined pads are preferred to keep the joint volume predictable; the datasheet lands pattern defines the reference footprint. Tape-and-reel (TR) is the standard reel format for this part, with cut-tape (CT) available for low-quantity prototyping runs — the PCB layout does not change between the two, only the lead-forming pitch on initial incoming inspection.","metaTitle":"1.5SMCJ45AS_R1_00001 TVS Diode, 1.5kW, 45V","metaDescription":"Unidirectional TVS diode, 1.5 kW peak pulse, 45 V standoff, 72.7 V clamping.
