CDSOT23-T05LC-Q from BOURNS, 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 | I/O | passive | I/O protected line; positive potential is applied from Pin 1 to Pin 2 (Pin 2 as ground) for VWM 5.0 V, VBR 6.0 V at 1 mA. |
| 2 | I/O | passive | I/O pin per the pin-out table; the page 1 note treats Pin 2 as the reference/ground side and says not to test or surge from Pin 2 to Pin 1. |
| 3 | N.C. | unconnected | No connection. |
