multicomp PRO Bipolar Transistor, Npn, 80V; Transistor Polarity Multicomp Pro TIP121

The TIP121 is an NPN Darlington transistor designed for general-purpose amplifier and low-speed switching applications. It has a collector-emitter voltage rating of 80V, a continuous collector current of 5A, and a maximum power dissipation of 65W at Tc = 25°C. The transistor features a minimum DC current gain of 1,000 at Ic = 3A and a collector-emitter saturation voltage of 2V maximum at Ic = 3A. It is housed in a TO-220 package with dimensions ranging from 14.68 to 15.31mm in length, 9.78 to 10.42mm in width, and 5.01 to 6.52mm in thickness. The junction temperature range is -65°C to +150°C, and thermal resistance from junction to case is 1.92°C/W.
