# MCH6448-VB

**VBsemi Elec** · MOSFETs · TSOP-6

MCH6448-VB from VBsemi Elec, in a TSOP-6. 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 | D | passive | Drain. One of four drain pins (1, 2, 5, 6) internally connected to reduce RDS(on) and improve thermal dissipation. VDS max 30 V. |
| 2 | D | passive | Drain. Internally tied to the other drain pins (1, 5, 6). VDS max 30 V; ID up to 6 A (TC=25 °C, package-limited). |
| 3 | G | input | Gate. Controls the N-channel MOSFET. VGS max ±20 V; VGS(th) 0.5-1.5 V; Qg ≈ 4.2 nC at VGS=4.5 V. |
| 4 | S | passive | Source. Return path for drain current; body-diode anode. Continuous source-drain diode current IS = 2.1 A (TC=25 °C). |
| 5 | D | passive | Drain. Internally tied to the other drain pins (1, 2, 6). Contributes to heat spreading through the leads (JEDEC MO-193C 6-lead TSOP). |
| 6 | D | passive | Drain. Internally tied to the other drain pins (1, 2, 5). VDS max 30 V. |

## CAD (KiCad official)

- Symbol: `MCH6448-VB`
- Footprint: `Package_SO:TSOP-6_1.65x3.05mm_P0.95mm`
- 3D model: TSOP-6 (KiCad packages3D, STEP)
- 3D model files: `mch6448-vb-etched.step` / `mch6448-vb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mch6448-vb.step` / `mch6448-vb.glb` are the bare package body.
