The BC638 is a versatile PNP bipolar transistor manufactured by Telefunken, suitable for moderately high voltage switching applications. It comes in a standard TO-92 package.
Key electrical specifications include a maximum collector-emitter voltage (VCE) of -60V and a continuous collector current (IC) of 1A. The device also features a maximum collector dissipation (Pc) of 1W and a transition frequency (fT) of 100MHz. Its DC current gain (hFE) can reach up to 160.
This transistor is designed for applications requiring moderate voltage switching, such as in the pre or mid-amplifier stages of power amplifiers. Its characteristics make it a cost-effective choice for general-purpose switching tasks. Proper biasing is crucial, as driving a load that consumes more than 1A may permanently damage the device. The maximum power dissipation of 1W must also be considered during design.
The BC638 is easily controlled by a small base current. As a PNP transistor, it turns on when the base is connected to ground and turns off when a positive voltage is applied to the base.
