概述
Description
BAT54C-QR is a dual Schottky diode array with a common cathode (BAT54C). It consists of two Schottky diodes in one SOT-23 (three-pin) package, sharing the cathode node and giving two independent anodes. The “-QR” suffix typically indicates Tape & Reel packaging for automatic assembly.
Key points:
- Configuration: two diodes with a common cathode (useful for OR-ing or clamping signals).
- Low forward voltage (typical ~0.2–0.3 V at modest current) and fast switching.
- Per-diode ratings (vendor variants vary): Vr (reverse voltage) ~30 V; If (continuous) on the order of a few hundred milliamps per diode.
- Low leakage and small capacitance, suitable for high-speed, low-voltage logic and protection circuits.
Common applications: logic-level ORing, input protection, rectification in low-voltage circuits, level shifting in digital or RF front-ends.
Note: Check the specific datasheet for exact electrical ratings, package details, and the exact meaning of the QR packaging for your supplier.
