Description
The BC557 is a commonly used PNP (Positive-Negative-Positive) bipolar junction transistor (BJT) known for its general-purpose amplification and switching capabilities in electronic circuits.
Here is a description of the BC557 PNP transistor:
Type: PNP (Positive-Negative-Positive) transistor.Polarity: The arrow in the transistor symbol points inward for PNP transistors.
Maximum Collector Current (IC): The BC557 can typically handle a continuous collector current of around 100 mA.
Maximum Collector-Emitter Voltage (VCE): The maximum voltage that can be applied across the collector and emitter is typically around 45 V.
Maximum Power Dissipation (Ptot): The BC557 can typically dissipate up to 500 mW without damage.
Applications:
The BC557 is commonly used in small-signal amplification circuits. It is suitable for switching applications in electronic circuits. Due to its small size and low power requirements, it is often used in low-power electronic devices.Pin Configuration
- Collector (C): It is the power supply input for the transistor.
- Base (B): It controls the current between the emitter and collector.
- Emitter (E): It is the output or common connection.
