# BZX79C2V7

**onsemi** · Zener Diodes · DO-35

BZX79C2V7 from onsemi, in a DO-35. 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 | CATHODE | passive | Cathode is marked by the color band on the DO-35 glass case, and the datasheet's forward-voltage limit (VF = 1.5 V max at IF = 100 mA) applies when the device is forward biased. |
| 2 | ANODE | passive | Anode is the terminal opposite the cathode band; the device is rated for forward operation at VF = 1.5 V max at IF = 100 mA, and for reverse Zener operation in the BZX79C2V7 range of 2.5 V to 2.9 V at IZ = 5 mA. |
