That 53.9 V clamp is what the downstream silicon sees — a 24 V-rated MOSFET with a 60 V drain-source breakdown has comfortable margin here, but a 40 V-rated part would be riding the edge. ## DO-214AB SMC — footprint and reflow Housed in a DO-214AB (SMCJ) surface-mount package, the same footprint used across the 1.5SMC family. Standard reflow profile for a JEDEC MSL-1 moisture-sensitive device — no bake required if the shelf life has been respected. Tape-and-reel packaging (the /57T suffix) feeds into automated pick-and-place; cut-tape quantities are also listed for prototype or low-volume builds. The 1.5SMC39CA-/57T carries an active lifecycle status from Vishay. Sourced through authorized distribution channels; availability and current pricing confirmed at RFQ for the required quantity. The base product number 1.5SMC39 covers both unidirectional (1.5SMC39A) and bidirectional (1.5SMC39CA) variants in the same package — confirm the suffix when ordering. No pin-compatible second-source is listed, but the DO-214AB footprint is shared by TVS diodes from several manufacturers if a cross-reference is needed.","metaTitle":"Vishay 1.5SMC39CA-E3/57T TVS Diode, 1.5kW, 33.3V Standoff","metaDescription":"Vishay 1.5SMC39CA-E3/57T bidirectional Zener TVS, 1500W peak pulse power, 33.3V reverse standoff, 53.9V clamping.
