Description
TIP122 NPN Darlington Transistor, TO-220
The TIP122 is an NPN Darlington power transistor in a TO-220 package. The current listing states a maximum collector current of 5 A and a collector-emitter voltage rating of 100 V.
- Type: NPN Darlington power transistor
- Package: TO-220
- Maximum collector current stated: 5 A
- Collector-emitter voltage stated: 100 V
- SKU: 0738
These are absolute maximum ratings and cannot necessarily be used simultaneously. The ST datasheet specifies collector-emitter saturation voltage up to 4 V at 5 A collector current and 20 mA base current, so allow for substantial power dissipation and heatsinking. Select base drive for the actual load, observe the safe operating area, and verify the pinout before wiring.
