Are BC547 and BC548 same?

This group of NPN transistors share many specifications and characteristic curves, but differ in voltage ratings – the BC546 and BC547 are essentially the same as the BC548 but selected with higher breakdown voltages, while the BC549 is a low noise version, and the BC550 is both high-voltage and low-noise.

What transistor is same with BC547?

BC548, BC549, BC636, BC639, 2N2222 TO-92, 2N2222 TO-18, 2N2369, 2N3055 and 2N3904 all are BC547 transistor equivalent.

What can I use instead of BC547 transistor?

2N2222 is the most common and excellent substitute for BC547. The only minor changes are in the input and output capacitance, which are slightly higher in case of 2N2222 and will only affect circuits during high frequency operation and not otherwise. Other substitutes include 2N3904, PN100, 2N4401, BC337, etc.

What does BC547 transistor work?

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. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit.

What is the difference between a BC547 and a BC548 transistor?

The BC547 and BC548 (and BC549 and BC546) are very similar transistors, but the BC547 has a higher voltage rating than a BC548 (or 9); the BC548 can be replaced by a BC547 but not usually the other way round – you risk blowing the transistor! Ditto for BC557 and BC558 – the -7 has a higher voltage rating than the -8.

What is the maximum current gain of BC547?

BC547 is mainly used for amplification and switching purposes. It has a maximum current gain of 800. Its equivalent transistors are BC548 and BC549. What is the difference between an SL100 transistor and a BC547 transistor?

What is the difference between a BC547 and a 2N2222A transistor?

The two major differences that I find are: the power dissipation (a measure of power that transistor can provide): 2N2222A – 625mW BC547 – 500mW

What is the difference between SL100 and BC547 transistors?

Both SL100 and BC547 are NPN transistors. SL100 is mostly used as switch in common emitter configuration. While BC547, combining with other electronic components, such as resistors, capacitors, can be used as the active component for switches and amplifiers. In SL100, 100 refers the gain of the transistor, while the maximum gain of BC547 is 800.
