DTC124EE from CBI, in a SOT-523. 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 | IN | input | Input through built-in R1 (22 kΩ typ) to the NPN base; input voltage range -10 to +40 V, VI(off) 0.5 V max and VI(on) 3 V min. |
| 2 | GND | power_in | Ground, connected to the emitter and to R2 of the built-in bias network. |
| 3 | OUT | output | Open-collector output of the NPN transistor; output current 30 mA max (IO), 100 mA peak, supply voltage 50 V max. |
