ChipNobo · Switching Diodes · SOT-323
BAV99WT1G-CN from ChipNobo, in a SOT-323. 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 | A1 | passive | Anode of the first diode, whose cathode connects to common pin 3; reverse voltage VR is 90 V and average rectified current IO is 150 mA. |
| 2 | K2 | passive | Cathode of the second diode, whose anode connects to common pin 3; reverse voltage VR is 90 V and average rectified current IO is 150 mA. |
| 3 | K1/A2 | passive | Common node joining the cathode of the first diode and the anode of the second diode in the series pair; peak forward surge current IFSM is 2.0 A at tp=1ms. |
