The 28.5V minimum breakdown voltage gives a 2.9V margin above the standoff — enough to avoid nuisance triggering on a regulated 24V bus while still clamping fast transients. This is a general-purpose protection diode for surface-mount layouts, not a power-line device. Housed in a DO-214AB (SMC) package, the same footprint as the SMCJ suffix. Will it survive hot air? Yes, the SMC body is molded epoxy with a thick copper leadframe; a 260°C peak reflow profile per J-STD-020 is standard. Pin 1 is the cathode band on the body, easy to spot under magnification. The bidirectional channel means a single device replaces two back-to-back Zeners on a bipolar signal line — saves board space and one solder joint. ## Lifecycle and sourcing posture The base product number 1.5SMC30 covers the whole voltage family; the -M3/9AT suffix denotes the lead-free, halogen-free plating and the Tape & Reel packaging for automated assembly. Sourced to order through independent distribution; availability and current pricing confirmed at RFQ.","metaTitle":"Vishay 1.5SMC30CA-M3/9AT TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC30CA-M3/9AT bidirectional Zener TVS, 1500W peak pulse, 25.6V standoff, 41.4V clamp.
