50WQ10FN

SMC Sangdest Microelectronicstronic Nanjing · Schottky Diodes · DPAK

50WQ10FN from SMC Sangdest Microelectronicstronic Nanjing, in a DPAK. 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	A1	passive	Anode of the first diode of the center-tap pair, with the common cathode on pin 2/tab; VRRM is 100 V.
2	K	passive	Common cathode (center tap), shown as base/cathode and connected to the tab; average forward current is 5.5 A total.
3	A2	passive	Anode of the second diode of the center-tap pair, with the common cathode on pin 2/tab; VRRM is 100 V.

CAD (KiCad official)

Symbol: 50WQ10FN
Footprint: Package_TO_SOT_SMD:TO-252-2
3D model: DPAK (KiCad packages3D, STEP)
3D model files: 50wq10fn-etched.step / 50wq10fn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 50wq10fn.step / 50wq10fn.glb are the bare package body.
