multicomp PRO Bipolar Transistor, Npn, To-92; Transistor Polarity Multicomp Pro 2N4401

The 2N4401 is an NPN silicon planar epitaxial transistor in a TO-92 plastic package, designed for general purpose switching applications. It has a collector-emitter voltage rating of 40 V, a continuous collector current of 600 mA, and a power dissipation of 625 mW at 25°C. The junction-to-ambient thermal resistance is 200 °C/W, and the operating and storage temperature range is -55°C to +150°C. The transition frequency exceeds 250 MHz, and the DC current gain ranges from 80 to 300 depending on collector current and voltage. The TO-92 package dimensions are specified with pin spacing and body size within defined tolerances.
