A2, August 2002 BC546/547/548/549/550 NPN Epitaxial Silicon Transistor Absolute Maximum Ratings Ta=25°C unless otherwise noted. BC547 is a general purpose NPN transistor which should be considered for use in design circuits requiring general purpose switching and amplification. Quick reference data Tamb = 25 °C unless otherwise specified. Delay On Timer Using BC547 Transistor & Relay 03/08/2016 RAJ SHARMA Leave a comment Power-ON Delay Switch which can be used in all applications requiring a delay during power-on from 10 seconds onwards. Top 5 BC547 transistor projects - Duration: 18:18. The BC547-9 series and BC557-9 series are functionally identical to the common BC107-9 series. Keep the positive probe to the center pin (Base) of the transistor. BC547 is an NPN bi-polar junction transistor. The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. A transistor is a device mostly used for switching purpose. Recalculate the emitter current for a transistor with β=100 and β=300. 0 Vdc Collector Current − Continuous IC 800 mAdc Total Device Dissipation @ TA = 25°C.
