BAS19LT1G

onsemi · Switching Diodes · SOT-23

BAS19LT1G from onsemi, in a SOT-23. 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 ANODE passive Anode terminal of the single high-voltage switching diode; the datasheet gives no pin-specific limits, so the device maximum ratings apply (continuous forward current 200 mA, repetitive peak forward current 0.6 A).
2 NC unconnected Designated NO CONNECTION in the SOT-23 Style 8 pin assignment, so this lead has no internal connection in this package.
3 CATHODE passive Cathode terminal of the diode; for the BAS19 the continuous reverse voltage and repetitive peak reverse voltage are both 120 V, and the BAS21 variant is rated 250 V.

  • Symbol: BAS19LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bas19lt1g-etched.step / bas19lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas19lt1g.step / bas19lt1g.glb are the bare package body.
