**Diodes Incorporated** · Zener Diodes · SOT-363

BZX84C24S-7-F from Diodes Incorporated, in a SOT-363. 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 | NC | unconnected | Not connected internally; the datasheet's top-view device schematic labels this position NC. |
| 2 | A2 | passive | Anode of the second zener diode in the dual package; total device dissipation is limited to 200mW (mounted on FR4 with recommended pad layout). |
| 3 | C2 | passive | Cathode of the second zener diode; zener voltage range is 2.4V to 39V depending on the part number, with a forward voltage of 0.9V at 10mA. |
| 4 | NC | unconnected | Not connected internally; the datasheet's top-view device schematic labels this position NC. |
| 5 | A1 | passive | Anode of the first zener diode in the dual package; total device dissipation is limited to 200mW (mounted on FR4 with recommended pad layout). |
| 6 | C1 | passive | Cathode of the first zener diode; zener voltage range is 2.4V to 39V depending on the part number, with a forward voltage of 0.9V at 10mA. |
