# BZX84-C5V1-JSM

**JSMSEMI** · Zener Diodes · SOT-23

BZX84-C5V1-JSM from JSMSEMI, 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 | Zener diode anode, shown as pin 1 in the connection diagram, at the triangle side of the symbol. |
| 2 | NC | unconnected | No connection, marked 2 NC in the connection diagram. |
| 3 | K | passive | Zener diode cathode, shown as pin 3 in the connection diagram, at the bar side of the symbol; Vz is 5.1V nominal (4.8V to 5.4V) at Izt=5.0mA. |

## CAD (KiCad official)

- Symbol: `BZX84-C5V1-JSM`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bzx84-c5v1-jsm-etched.step` / `bzx84-c5v1-jsm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84-c5v1-jsm.step` / `bzx84-c5v1-jsm.glb` are the bare package body.
