1.5 kW Zener TVS in a hermetic SQ-MELF package
It clamps at 103.1 V maximum at 14.5 A peak pulse current, with a reverse standoff voltage of 56 V. The SQ-MELF (C) package is a hermetic, surface-mount ceramic body suited for high-reliability and military-grade applications.
The 103.1 V clamp voltage at 14.5 A sets the upper stress limit the downstream circuitry must survive. With a breakdown voltage minimum of 71.3 V, the device triggers before the protected node exceeds its rating. The 1.5 kW peak pulse rating is the energy-handling capacity for a single surge — derate for shorter or repetitive events per the datasheet curve.
Temperature range and package — design-in checklist
The SQ-MELF (C) package is a hermetic ceramic body with surface-mount solder pads — no through-hole leads. The bidirectional configuration (single channel) protects against both positive and negative transients on a single line.
