D204S

Senba Sensing Tech · Biometric Sensors · TO-5-3

D204S from Senba Sensing Tech, in a TO-5-3. 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 Drain power_in JFET drain, connected to the supply (+VDD) through an EMI filter; supply voltage range 3~15V (5V in the test circuit).
2 Source output JFET source-follower output, loaded by a source resistor Rs (47kΩ in the test circuit) to ground; source voltage 0.3~1.2V.
3 Ground power_in Ground (GND) connection of the sensor.

CAD (KiCad official)

  • Symbol: D204S
  • Footprint: Package_TO_SOT_THT:TO-5-3
  • 3D model: TO-5-3 (KiCad packages3D, STEP)
  • 3D model files: d204s-etched.step / d204s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); d204s.step / d204s.glb are the bare package body.
