Zener TVS protection in a SQ-MELF package
It delivers 500W peak pulse power per the 10/1000µs waveform, with a reverse standoff voltage of 40.3V and a maximum clamping voltage of 63.5V at the rated peak pulse current. The unidirectional channel protects a single rail or signal line.
Surface-mount SQ-MELF B package — the barrel-shaped body demands careful solder-paste volume control during reflow to avoid voids under the termination bands.
The 175°C TJ rating is the ceiling for derating the 500W pulse capability — at high ambient, the peak pulse power must be reduced per the thermal derating curve in the datasheet.
