The 1.5SMC33A V7G: When a surge hits, breakdown triggers at 31.4V min and the clamp holds the peak at 45.7V max while shunting 34A (10/1000µs waveform). For a 33V rail, this means the diode absorbs a 34A, 45.7V transient without exceeding its junction temperature limit of 150°C.
Package and board-fit for a surface-mount transient clamp
The package footprint is standard for the SMC body size, compatible with reflow profiles typical for lead-free solder. The wide range means derating for high-temperature operation is minimal for most line-side protection applications.
