Description
BAV99QAZ is a dual series switching diode in a single SOT-23 package. It contains two diodes wired in series: D1 from pin 1 to pin 2 (anode at pin 1, cathode at pin 2) and D2 from pin 2 to pin 3 (anode at pin 2, cathode at pin 3). The middle pin (pin 2) is the common node.
Uses:
- High-speed signal switching, clipping/limiting, and simple level-shifting networks
- Protection and conditioning in compact, low-power circuits
Why choose it:
- Small-signal, fast switching diodes with low leakage
- Very compact three-pin package suitable for SMD designs
Notes:
- Electrical ratings (forward drop, reverse voltage, current) vary by vendor; consult the datasheet for exact values.
- "QAZ" is a vendor/lot code indicating a specific variant of the BAV99 family (often RoHS-compliant).
Pinout reminder: pin 1 = D1 anode, pin 2 = D1 cathode and D2 anode, pin 3 = D2 cathode.
