S-LDTB113ZLT1G from LRC, 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 | BASE | input | Input terminal of the bias resistor transistor, with built-in bias resistor R1 = 1 kΩ and R2 = 10 kΩ per the device marking table, and input voltage limited to −10 V to +5 V (absolute maximum ratings). |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet gives no separate emitter-specific rating beyond the absolute maximum ratings. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor (output side of the inverter), with supply voltage VCC rated at −50 V maximum and output current IC rated at −500 mA maximum. |
