DDZ9708Q-7

Diodes Incorporated · Zener Diodes · SOD-123

DDZ9708Q-7 from Diodes Incorporated, in a SOD-123. 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 K passive Cathode, the terminal marked by the cathode band; the zener (VZ) is reached with this terminal positive relative to the anode, with VZ 20.90 to 23.10 V at IZT 50 µA for the DDZ9708 type.
2 A passive Anode, the terminal opposite the cathode band; forward voltage is 0.9 V at IF = 10 mA.
