Its Darlington pair gives a high current gain (hFE at least 1000 at 3 A), so a small base current from an MCU or logic pin can switch large loads like motors, relays, solenoids, and lamps. It comes in a TO-220 package with integrated base-emitter resistors (7 kΩ and 70 Ω) and an internal collector-emitter diode. ## Pinout @@ -19,10 +19,10 @@ The TIP120 is an NPN Darlington power transistor rated for 60 V and 5 A continuo | Type | NPN Darlington power transistor | | Collector-emitter voltage (VCEO) | 60 V | | Collector current (IC) | 5 A continuous (8 A peak) |-| DC current gain (hFE) | 1000 min, 2500 typ at 3 A |+| DC current gain (hFE) | 1000 min at 0.5 A and at 3 A (VCE = 3 V) | | Power dissipation | 65 W | | VCE(sat) | 2.0 V at 3 A |-| Operating temperature | -65 C to 150 C |+| Junction temperature | 150 °C max (storage -65 °C to 150 °C) | ## CAD (KiCad official)
