Device identity and protection profile
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. The bidirectional nature simplifies layout for AC-coupled or bipolar signal lines.
which is typical for small-quantity engineering samples or low-volume production.
