MJD122D
Slkor SLKORMICRO Elec · Bipolar (BJT) · TO-252
MJD122D from Slkor SLKORMICRO Elec, in a TO-252. 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 of the NPN Darlington transistor; Emitter-Base voltage is limited to 5 V maximum (VEBO). |
| 2 | Collector | passive | Collector of the Darlington transistor (also the tab); VCBO and VCEO are 100 V maximum and continuous collector current is 8 A maximum. |
| 3 | Emitter | passive | Emitter of the Darlington transistor, connected to the internal 0.12 kΩ resistor and the integrated diode as shown in the schematic. |
