Visão Geral
Description
BAT54SW-QX is a dual Schottky barrier diode pair in a single SOT-23 package with a common cathode. It’s used for fast switching, low-voltage signal routing, clamping, and protection in compact circuits.
Key points:
- Configuration: two Schottky diodes sharing a cathode (three-pin SOT-23: two anodes, one common cathode).
- Electricals (variant-dependent; check the datasheet): low forward voltage around 0.2–0.3 V at modest current; reverse voltage typically ~25 V; forward current per diode on the order of 100–200 mA; very low leakage at room temp.
- Benefits: fast switching, low VF, low storage time, RoHS-compliant.
- Typical uses: OR-ing, level shifting, clamping, input protection in low-voltage logic and power circuits.
- Note: The “QX” suffix denotes a specific packaging/variant from a manufacturer; always consult the exact datasheet for exact ratings, pinout, and temperature range.
