BZD27C75P
LGE · Zener Diodes · SOD-123FL
BZD27C75P from LGE, in a SOD-123FL. 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, marked by the cathode band (color band denotes positive end); zener working voltage Vz is 70 V min to 79 V max at IZT = 10 mA for the BZD27C75P. |
| 2 | A | passive | Anode of the zener diode; the datasheet does not print pin numbers, only the cathode band on the SOD-123FL case. |
