GS8621-TR

Gainsil · Low Noise Amplifiers (LNA) - RF · SOT-23-5

GS8621-TR from Gainsil, in a SOT-23-5. 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 OUT output Amplifier output with rail-to-rail swing, able to drive heavy loads (53 mA typical output current at 5V).
2 VSS power_in Negative supply pin, connected to ground in single-supply operation; the supply range VDD to VSS is 2.1V to 5.5V.
3 IN+ input Non-inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and an absolute maximum input voltage of VSS-0.5V to VDD+0.5V.
4 IN- input Inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and an absolute maximum input voltage of VSS-0.5V to VDD+0.5V.
5 VDD power_in Positive supply pin, operating from 2.1V to 5.5V (absolute maximum 7.5V relative to VSS), with a 0.1uF ceramic bypass capacitor placed close to it.

CAD (KiCad official)

  • Symbol: GS8621-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs8621-tr-etched.step / gs8621-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8621-tr.step / gs8621-tr.glb are the bare package body.
