Description
BAT54SQ-7-F is a dual Schottky barrier diode from the BAT54 family in a compact SMD package. It contains two Schottky diodes in one device, delivering very low forward voltage drop and fast switching. Typical uses include low‑voltage protection, input clamping, rectification, and OR-ing in small, low-power circuits. The -F suffix usually indicates a Pb‑free (RoHS-compliant) variant, and SQ denotes the specific package/style for this device. Exact electrical ratings (reverse voltage, forward current, leakage) and the diode configuration (common anode/cathode) depend on the specific variant and package, so consult the latest datasheet for BAT54SQ-7-F to verify pinout and electrical specs for your design.
Equivalent
Equivalents: other BAT54-family dual Schottky parts such as BAT54S, BAT54C, BAT54A (from Diodes Inc, Nexperia, ON Semi, etc.), SBAT54 or manufacturer cross‑releases of BAT54SQ. You can also substitute any dual Schottky diode with the same package/pinout and comparable Vf/If (check datasheets). Always verify pinout, forward voltage, leakage and package before replacing.
Features
- Dual Schottky barrier diodes in a single SOT-23 package (BAT54SQ-7-F)
- Very low forward voltage drop (approx. 0.2–0.3 V at moderate current)
- Fast switching suitable for high-speed rectification and logic-level applications
- Reverse voltage (VRRM) about 30 V; forward current (IF) up to ~200 mA
- Low leakage current
- RoHS compliant, Pb-free, halogen-free; surface-mount device
- Suitable for protection, clamping, level shifting, and diode-OR applications
- Wide operating temp range (typically -55°C to 150°C)
Note: exact electricals can vary slightly by lot and package variant; consult the specific datasheet for precise values.
