500W bidirectional Zener TVS in SQ-MELF
Its 5.7V reverse standoff voltage lets it sit across a 5V rail without leakage, while the 7.13V minimum breakdown voltage triggers clamping at 11.2V maximum under a 44.6A peak pulse current. The SQ-MELF, B package (surface-mount MELF) provides a low-inductance path for fast transients and handles reflow soldering without special handling. The single bidirectional channel simplifies layout for AC or bipolar signal lines — no need to orient the part.
Junction temperature range and application fit
The 500W pulse power at 25°C derates linearly above that; at 175°C the capability drops to roughly 20% of the 25°C rating. No power line protection (: No) — this is a signal-line or low-voltage rail TVS, not a mains surge suppressor. Use it on 5V data lines, sensor inputs, or control buses where the 5.7V standoff gives margin above the nominal rail.
