12/4/2023 0 Comments Bc557 vs bc547Instead of a transistor BC547, you can use BC546 or BC550, BC847(plastic surface mounted package. Please enter a valid full or partial manufacturer part number with a minimum of 3 letters or numbers. The complementary p-n-p transistor to the BC547 is the BC557. In order to drive the output first know the current requirement of your output if it requires approx 600mA current then a normal BJT will do the job but when it comes to drive high power ouput devices such as high power led which requires about 1A current then you have to go for Darlington Pair NPN BJT Transistors. BC337 BC547 datasheet, cross reference, circuit and application notes in pdf format. BC546 / BC547 / BC548 / BC549 / BC550 Rev. 1.7 1 January 2016 BC556 / BC557 / BC558 / BC559 / BC560 PNP Epitaxial Silicon Transistor Features Switching and Amplifier High-Voltage: BC556, VCEO -65 V Low-Noise: BC559, BC560 Complement to BC546, BC547, BC548, BC549, and BC550 Ordering Information Part Number Marking Package. BC557 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at ground and will be opened (Reverse biased) when a signal is provided to base pin.
