BZV49-C11

Nexperia · Zener Diodes · SOT-89-3

BZV49-C11 from Nexperia, in a SOT-89-3. 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 anode passive Anode terminal of the BZV49-C11 voltage regulator diode (11 V nominal working voltage, VZ 10.4 to 11.6 V at IZtest 5 mA), with 0.4 W...
