What this Zener TVS does for your board
It clamps transients at 14.07V maximum while standing off 6.9V continuously — a tight ratio that keeps protected rails from seeing overshoot during surge events. A single device covers both polarities, so you don't need back-to-back Zeners on AC-coupled or bidirectional signal lines.
Minimum breakdown voltage is 8.22V, which means the diode starts conducting just above the 6.9V standoff level. The 14.07V clamp ceiling limits the voltage the protected circuit sees during a 35.44A peak pulse current event. No power-line protection — this part is intended for signal or low-voltage DC rail clamping, not AC mains.
Temperature range and package — where it fits
The SQ-MELF (B case) is a hermetic-style surface-mount package — no exposed leads, good for high-reliability and conformal-coated assemblies. Hand-solderable with care; the barrel body needs a steady iron and good flux.
Active production — sourcing posture
Microchip lists the 1N6105US as Active. Sourced per RFQ against your BOM quantity — current pricing and lead time confirmed at quote time.
