BC639 High Current NPN Transistor 80V 1A TO-92

BC639 High Current NPN Transistor 80V 1A TO-92 The BC639 is an NPN epitaxial silicon transistor designed for switching and amplifier applications. It provides a collector current rating of up to 1A, making it suitable for driving moderate-current loads and as a general-purpose transistor in electronic circuits. The device is supplied in a compact TO-92 package. The BC639 offers an 80V collector-emitter voltage rating, a peak collector current of 1.5A, and a maximum collector power dissipation of 1W. It features a DC current gain of up to 160 under the specified test conditions and a collector-emitter saturation voltage of up to 0.5V at 500mA collector current.
