Device identity and protection profile
The 1N6107AUS is a Zener transient-voltage suppressor (TVS) from Microchip Technology, designed to clamp overvoltage transients on a supply or signal line. It is a bidirectional single-channel device, meaning it can handle surges of either polarity without needing a series diode. Rated for 500W peak pulse power per the 10/1000 µs waveform, it can absorb 32A peak pulse current before the clamping voltage rises to 15.6V maximum. The reverse standoff voltage is 8.4V typical, so the line it protects should normally stay below that level. The SQ-MELF B package is a hermetic surface-mount ceramic body, suited for high-reliability environments where moisture resistance and thermal cycling are concerns.
Minimum breakdown voltage is 10.45V, so the device starts conducting in avalanche at that threshold. The clamping voltage at peak current is 15.6V max — this is the voltage the protected circuit must survive during a surge event. No power line protection feature is built in, so this part is intended for signal or low-power rail clamping rather than mains-level AC line protection. The bidirectional nature simplifies layout for AC-coupled or bipolar signal lines.
