BC557B Description
The BC557B is a PNP transistor, the collector and emitter are closed (forward biased) when the base pin is held at the ground and open (reverse biased) when a signal is applied to the base pin.
BC557B Features
Bi-Polar PNP Transistor
DC Current Gain (hFE) is 300 maximum
Continuous Collector current (IC) is 100mA
Emitter Base Voltage (VBE) is 6V
Base Current(IB) is 5mA maximum
Available in TO-92 Package
BC557B Applications
Driver Modules like Relay Driver, LED driver etc.
Amplifier modules like Audio amplifiers, signal Amplifiers etc.
Darlington pair.
