NSR05F20NXT5G

onsemi · Schottky Diodes · 0402

NSR05F20NXT5G from onsemi, in a 0402. 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 CATHODE passive Cathode terminal of the 20 V Schottky barrier diode; pin 1 is the cathode and is marked by the PIN 1 indicator and cathode band on the package.
2 ANODE passive Anode terminal of the 20 V Schottky barrier diode, which carries the forward current (500 mA continuous, 10 A surge at 60 Hz for one cycle, per the maximum ratings).

CAD (KiCad official)

  • Symbol: NSR05F20NXT5G
  • Footprint: Diode_SMD:D_0402_1005Metric
  • 3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal 0402 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: nsr05f20nxt5g-etched.step / nsr05f20nxt5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nsr05f20nxt5g.step / nsr05f20nxt5g.glb are the bare package body.
