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. |
