LRC · Digital Transistors · SOT-723
LDTC143ZM3T5G from LRC, in a SOT-723. 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 | BASE | input | Base input pin of the bias resistor transistor, connected to the internal series base resistor R1 of the monolithic bias network. |
| 2 | EMITTER | power_in | Emitter pin, designated GROUND in the datasheet, and connected internally to the base-emitter resistor R2. |
| 3 | COLLECTOR | output | Collector output pin; the series maximum ratings are VCEO 50 Vdc and collector current IC 100 mAdc. |
