The SQ-MELF (B) package is a surface-mount glass-passivated ceramic body — same footprint as a standard MELF but square, which helps with pick-and-place alignment and solder-joint inspection. ## 11.4V breakdown – the margin above a 9.1V rail With a 9.1V reverse standoff, the device stays off during normal 9V or 12V bus operation. The 11.4V minimum breakdown gives a 2.3V guard band before conduction starts — enough to absorb steady-state ripple without self-heating. The 16.9V clamp at 29.6A limits the voltage spike seen by downstream components during a surge event. For a 500W rating at 10/1000µs, that clamp voltage translates to roughly 29.6A peak current handling per the datasheet waveform. ## Active production – sourcing posture Microchip lists the 1N6108AUS as Active with no announced end-of-life. The SQ-MELF package is a standard Microchip hermetic offering, so supply continuity is typical for this product family. ## Bidirectional channel – one device for AC or bipolar lines A single bidirectional channel means the 1N6108AUS clamps both polarities symmetrically — useful on signal lines that swing above and below ground, or on AC-coupled data interfaces. The SQ-MELF body is rated for a -55°C to 175°C junction temperature range, so it fits military, avionics, and downhole environments where the board sees wide thermal cycling.","metaTitle":"1N6108AUS Zener TVS Diode – 500W, 9.1V Standoff, SQ-MELF","metaDescription":"1N6108AUS bidirectional Zener TVS, 500W peak pulse, 11.4V min breakdown, 16.9V clamp.
