| Market Reality | The TIP122 is the relay, solenoid and lamp driver of two generations of industrial boards - a TO-220 Darlington with a gain over 1000, so a few milliamps of base current switch amps of load. The family is a voltage ladder (TIP120 at 60V, TIP121 at 80V, TIP122 at 100V; the PNP halves are TIP125/126/127), and the buying decisions are two: which voltage grade the rail actually needs, and whether the position should become a MOSFET. The characteristic Darlington price is a saturation voltage of about 2V - at 5A that is 10W inside the package - which is exactly why so many of these positions get converted. | - |
