multicomp PRO Bipolar Transistor, Npn, 40V, To-92; Transistor Polarity Multicomp Pro 2N3904

The 2N3904 is an NPN silicon planar switching transistor in a TO-92 package, designed for general-purpose switching and amplification. It has a collector-emitter voltage rating of 40V, a continuous collector current of 200mA, and a power dissipation of 625mW at 25°C, derating at 5mW/°C above that temperature. The junction-to-ambient thermal resistance is 200°C/W, and the operating and storage temperature range is -55°C to +150°C. The transistor exhibits a DC current gain (hFE) of 100 to 300 at 10mA collector current, a collector-emitter saturation voltage of less than 0.3V at 10mA and 1mA base current, and a transition frequency of at least 300MHz. The physical dimensions are 4.32 to 5.33mm in height, 4.45 to 5.2mm in body width, and 3.18 to 4.19mm in lead spacing. The part meets RoHS standards.
