Présentation
Description
BAS40-04-QR is a dual fast-switching diode from the BAS40 family, packaged in a compact QR (RoHS/lead-free) SMD package. It contains two diodes in one device and is commonly used for high-speed signal switching, clamping, or simple rectification in small-signal circuits.
Key points:
- Package: small SMD QR package; check exact pinout in the datasheet.
- Performance: low forward voltage drop, fast switching, and low junction capacitance typical of fast diodes.
- Ratings: reverse voltage, continuous forward current, leakage, and switching characteristics vary by variant—consult the datasheet for exact numbers.
- Typical uses: logic-level signal routing, peak-detection, demodulation, protection/clamping, and compact OR-ing in RF and digital circuits.
Note: “-QR” indicates RoHS-compliant, lead-free construction. For precise electrical specs and pin configuration, refer to the specific BAS40-04-QR datasheet from the manufacturer.
