BAT54WSQ-7-F

BAT54WSQ-7-F is a dual Schottky barrier rectifier in one compact package. It provides two fast, low-forward-voltage diodes in a common configuration (usually common cathode); ideal for low-voltage rectification, protection, and OR-ing in compact circuits.
Key points
- Configuration: dual Schottky diodes (typical common cathode); verify exact pinout in the datasheet for this variant.
- Voltage/current: reverse voltage in the tens of volts range (typical around 30 V); forward current about 0.2 A per diode; very low forward voltage (≈0.25–0.30 V at modest current).
- Benefits: fast switching, low Vf, small footprint, RoHS/lead-free.
- Applications: input protection, polarity protection, power-management circuits, rectification in low-voltage, high-speed apps.
Note: exact electrical limits and pinout depend on the specific manufacturer revision of the -F version. Always consult the official datasheet for BAT54WSQ-7-F for precise specs.

Equivalents are other members of the BAT54 dual Schottky family with the same package/pinout: e.g. BAT54S/BAT54C/BAT54A variants (choose the correct anode/cathode configuration). Vendor cross-references include Vishay, ON Semiconductor, Nexperia and Diodes Inc. Always verify package, pinout, Vf, reverse voltage and leakage before substituting.
