BUK9219-55A

Nexperia · MOSFETs · DPAK

BUK9219-55A from Nexperia, in a DPAK. 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 G input Gate. Logic-level MOSFET control input; VGS(th) typ 1.5 V (1 V min, 2 V max at ID = 1 mA, Tj = 25 °C). Absolute maximum VGS = ±10 V DC (pulsed VGSM = ±15 V, tp ≤ 50 µs). Input capacitance Ciss typ 2190 pF.
2 D passive Drain. MOSFET drain terminal; VDS max 55 V, ID max 55 A (Tmb = 25 °C, VGS = 5 V), peak IDM 219 A (tp ≤ 10 µs). Electrically connected to the mounting base (mb) tab.
3 S passive Source. MOSFET source terminal; body-diode source current IS max 55 A, peak ISM 219 A (tp ≤ 10 µs). Serves as the reference for VGS and VDS.
mb D passive Mounting base (exposed tab). Internally connected to the drain; acts as the primary thermal path (Rth(j-mb) max 1.3 K/W). Solder to a copper pad on the drain net for heat dissipation.

  • 3D model files: buk9219-55a-etched.step / buk9219-55a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); buk9219-55a.step / buk9219-55a.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (14 pp, sha256 f6a9386c415dd569, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
