BAV199WQ-7

Diodes Incorporated · Diodes - General Purpose · SOT-323-3

BAV199WQ-7 from Diodes Incorporated, in a SOT-323-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Terminal at the bottom-left of the top-view internal schematic, the free end of the first diode of the dual series pair (85 V VRRM, 160 mA single-diode continuous current).
2 K2 passive Terminal at the bottom-right of the top-view internal schematic, the free end of the second diode of the dual series pair (85 V VRRM, 140 mA double-diode continuous current).
3 COMMON passive Top terminal of the top-view internal schematic, the node shared by both diodes of the dual low-leakage pair (IR max 5.0 nA at VR = 75 V).
