1500W bidirectional Zener TVS in SQ-MELF
The 1N6141US is a bidirectional Zener transient-voltage-suppression diode rated for 1500 W peak pulse power at 10/1000 µs waveform. Its 6.9 V reverse standoff voltage and 13.4 V clamping maximum at 111.9 A peak pulse current define the protection envelope for a 5 V or 6 V rail. The SQ-MELF, C package is a hermetic surface-mount ceramic body — common in high-reliability and military/aerospace designs where moisture resistance and thermal cycling matter.
Parametric boundaries and thermal reach
Breakdown voltage minimum is 8.65 V, giving a guard band above the 6.9 V standoff. No power line protection, so this part is intended for signal or low-voltage DC rail clamping, not AC mains.
Active production and package form
. The SQ-MELF footprint is a non-standard surface-mount outline; confirm the land pattern matches the C variant before layout. Sourced and quoted per RFQ — no stock-holding claim, but the active status means authorized-distributor lead times are the norm.
