1500 W peak pulse — the surge rating that defines the part
The 1.5SMC110A_R1_00001: The 105 V minimum breakdown voltage and 152 V maximum clamping define the window between normal operation and full clamp: the rail must stay below 94 V for the diode to remain off, and the transient must not exceed 152 V to keep the protected node safe.
Single unidirectional channel — polarity matters
This is a single-channel unidirectional Zener TVS, so it clamps only one polarity — positive transients above breakdown are shunted to ground, while reverse voltage below the forward diode drop conducts like a standard rectifier. For bidirectional protection on AC or bipolar rails, two devices or a bidirectional variant is needed.
DO-214AB SMC — board-fit and thermal note
Housed in the DO-214AB (SMC) surface-mount package, the same footprint used across the 1.5SMC series. Supplied on Tape & Reel (TR) or Cut Tape (CT), compatible with standard pick-and-place assembly. The SMC body is roughly 7.0 mm × 6.0 mm — confirm clearance to adjacent tall components on the reflow side.
General purpose — no automotive grade on record
For automotive or high-reliability programs requiring PPAP or specific reliability screening, a separately qualified variant from the 1.5SMC family would be needed.
