DDZX5V1B-7
Diodes Incorporated · Zener Diodes · SOT-23
DDZX5V1B-7 from Diodes Incorporated, in a SOT-23. 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 | A | passive | Anode of the zener diode, shown on a bottom-left pin in the device schematic; the datasheet gives VZ of 4.94V to 5.20V at IZT = 20mA for the DDZX5V1B. |
| 2 | NC | unconnected | No internal connection; the second bottom pin is shown unconnected in the device schematic. |
| 3 | K | passive | Cathode of the zener diode, shown on the single top pin in the device schematic; maximum power dissipation is 300mW on FR-4 PCB. |
