# ZRC330F03TA

**Diodes Incorporated** · Voltage Reference · SOT-23

ZRC330F03TA from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC/GND | passive | No internal connection. Per datasheet, pin 1 may be left floating or tied to pin 2 (GND). |
| 2 | GND | passive | Ground / anode of the shunt reference. Return terminal for reverse current through the reference. |
| 3 | VR | passive | Reference (cathode) terminal. Regulates to VR = 3.3V nominal when biased through a series resistor from a higher supply. Recommended operating current 20µA-5mA (25mA absolute max). |

## CAD (KiCad official)

- Symbol: `ZRC330F03TA`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `zrc330f03ta-etched.step` / `zrc330f03ta-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `zrc330f03ta.step` / `zrc330f03ta.glb` are the bare package body.
