This NPN transistor finds use in most projects where switching or amplifying small signals is required. Small Signal Transistors such as this are transistors that are used to amplify low-level signals but can also can be used as a switch.Typical hFE (DC current gain) values for small signal transistors range from 70 to 700, with maximum Ic ratings from about 80 to 600mA. Maximum operating frequencies range from about 1 to 300 MHz. Small signal transistors are used primarily when amplifying small signals, such as a few volts and only when using milliamperes of current. When building projects requiring larger voltage and current (larger power), using many volts or amperes of current, a power transistor should be used.
