# DOS4614S

**DOINGTER** · MOSFETs · SOP-8

DOS4614S from DOINGTER, in a SOP-8. 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 | S1 | passive | Source of the N-channel MOSFET (40V VDS, 6.7A continuous drain current). |
| 2 | G1 | input | Gate of the N-channel MOSFET, with VGS limited to ±20V and a 1V to 2.5V threshold. |
| 3 | S2 | passive | Source of the P-channel MOSFET (-40V VDS, -6A continuous drain current). |
| 4 | G2 | input | Gate of the P-channel MOSFET, with VGS limited to ±20V and a -1.0V to -2.5V threshold. |
| 5 | D2 | passive | Drain of the P-channel MOSFET, joined to pin 6 (VDS -40V, pulsed ID -20A). |
| 6 | D2 | passive | Drain of the P-channel MOSFET, joined to pin 5 (VDS -40V, pulsed ID -20A). |
| 7 | D1 | passive | Drain of the N-channel MOSFET, joined to pin 8 (VDS 40V, pulsed ID 26.8A). |
| 8 | D1 | passive | Drain of the N-channel MOSFET, joined to pin 7 (VDS 40V, pulsed ID 26.8A). |

## CAD (KiCad official)

- Symbol: `DOS4614S`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `dos4614s-etched.step` / `dos4614s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dos4614s.step` / `dos4614s.glb` are the bare package body.
