1500W Zener TVS in DO-214AB SMC
The 1.5SMC43AS_R1_00001: This is a general-purpose transient suppressor for 36V nominal rails — think 24V systems with margin, or 28V avionics buses where a 36.8V standoff keeps the diode out of conduction during normal operation.
The SMC body has a larger copper pad area than the smaller SMA/SMB siblings, which helps pull heat from the die during repetitive surge events — relevant if the board sees multiple transients, not just a single pulse. Available in both Tape & Reel and Cut Tape options — the reel suits automated pick-and-place for volume builds, while Cut Tape works for prototype or low-quantity runs.
