# TPZ3V6CS3

**TECH PUBLIC** · Zener Diodes · SOT-23

TPZ3V6CS3 from TECH PUBLIC, 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 terminal 1 (anode, per the internal diagram connecting pin 1 to the diode); the TPZ3V6CS3 has a nominal Vz of 3.6V (3.4V to 3.8V) at IZT=5mA. |
| 2 | NC | unconnected | Pin 2 is drawn in the internal diagram with no connection to the diode. |
| 3 | K | passive | Zener diode terminal 3 (cathode, per the internal diagram connecting pin 3 to the diode); power dissipation is 350mW maximum. |

## CAD (KiCad official)

- Symbol: `TPZ3V6CS3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tpz3v6cs3-etched.step` / `tpz3v6cs3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpz3v6cs3.step` / `tpz3v6cs3.glb` are the bare package body.
