# TPF111U-CR

**3PEAK** · Video Amplifiers · SOT-353

TPF111U-CR from 3PEAK, in a SOT-353. 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 | VIN | power_in | Video input; absolute maximum input voltage is VDD + 0.3V to GND - 0.3V, and the application notes require the input signal to stay between 0 and VDD/2 because of the internal 6dB gain. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | +VS | power_in | Positive single supply, specified from +2.85V to +5.5V with an absolute maximum of 6.0V. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | VOUT | output | Filtered video output with rail-to-rail swing and short-circuit current up to 65mA, which allows it to drive two video lines or 75Ω; AC coupling with a 220µF capacitor is recommended when used. |

## CAD (KiCad official)

- Symbol: `TPF111U-CR`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `tpf111u-cr-etched.step` / `tpf111u-cr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpf111u-cr.step` / `tpf111u-cr.glb` are the bare package body.
