Frequently Asked Questions
How much collector current can the TIP112 handle in switching applications?
The TIP112 is rated for a 2A maximum collector current and a 100V collector-emitter breakdown voltage, making it well suited for high-current Darlington switching in relay and motor-driver circuits.
Why can the TIP112 be driven with such a small base current?
This Darlington transistor delivers a minimum DC current gain (hFE) of 500 alongside a built-in base-emitter diode, letting it switch loads up to 2A from a very small base-drive signal.
How many leads does the TIP112's TO-220AB package provide for mounting?
The TIP112 ships in a 3-pin TO-220AB through-hole package, providing a rugged mounting tab for heatsinking in power designs handling up to 100V and 2A.
