BC557 is a bi-polar general purpose PNP transistor that is commonly used in switching and amplifying applications. The connection between the collector and emitter pin remains closed till a base voltage is applied to it. When a base voltage is applied the connection is opened thus opening the load.

BC557 Transistor Features:

• Continuous Collector Current: 100mA
• Collector Emitter Voltage: 50V
• Base Trigger Voltage: 6V
• Base Current: 5mA
• Current Gain: 300 (max)
• Type: PNP
• Package: TO-92

BC557 Transistor Applications:

 

• Driver Modules like Relay Driver, LED driver etc..
• Amplifier modules like Audio amplifiers, signal Amplifier etc..
•  Darlington pair
