YS3402-VB

VBsemi Elec · MOSFETs · TSOP-6

YS3402-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 terminal of the N-channel MOSFET. Tied internally to the drain along with pins 5 and 6. Rated VDS = 30 V, continuous ID up to 6 A at TC = 25 °C.
2 D passive Drain terminal of the N-channel MOSFET. Internally connected to the other drain pins (1, 5, 6). Rated VDS = 30 V.
3 G input Gate terminal of the N-channel MOSFET. VGS absolute maximum ±20 V; typical VGS(th) = 0.5 V to 1.5 V at ID = 250 µA. Internal Rg (typ.) = 12.6 Ω.
4 S passive Source terminal of the N-channel MOSFET. Body diode anode; body diode voltage VSD ≈ 0.82 V (typ.) at IS = 4.4 A.
5 D passive Drain terminal of the N-channel MOSFET. Internally connected to the other drain pins (1, 2, 6). Rated VDS = 30 V.
6 D passive Drain terminal of the N-channel MOSFET. Internally connected to the other drain pins (1, 2, 5). Rated VDS = 30 V; body diode cathode.

CAD (KiCad official)

  • Symbol: YS3402-VB
  • Footprint: Package_SO:TSOP-6_1.65x3.05mm_P0.95mm
  • 3D model: TSOP-6 (KiCad packages3D, STEP)
  • 3D model files: ys3402-vb-etched.step / ys3402-vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ys3402-vb.step / ys3402-vb.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: VBsemi Elec datasheet (None pp, sha256 e82e009668664309, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
