BC527 Transistor Explained / Description:

Previously we have discussed BC537 transistor which is an interesting small signal transistor with some good qualities. Today we are going to discuss its PNP complimentary which also has same feature and electrical characteristics such as good collector-emitter voltage, collector current of upto 1A, transition frequency of up to 100MHz, availability of NPN complimentary transistor, and DC current gain of 40 to 400.

The absolute maximum ratings of the transistor are as follow: collector-emitter voltage is -60V, collector current is -1A, collector-base voltage is also -60V, emitter-base voltage is 6V, total power dissipation is 625mW and junction and storage temperature is from -55°C to 150°C.

The DC current gain or hFE of the transistor is 40 to 400 but you will not find it in a single transistor. The transistors are manufactured in different gain variations so each user can the required gain transistor for their circuit. The transistor is available in 4 different gain variations which can be identified with the code number after the part number of the transistor. Here are the code numbers through which you can identify the DC current gain of the transistor.

Code No.6           =       hFE Value 40 to 100

Code No.10         =       hFE Value 63 to 160

Code No.16         =       hFE Value 100 to 250

Code No.25         =        hFE Value 160 to 100

 

All the good feature and characteristics of this transistor makes it ideal to be used in wide variety of applications. The application list is mentioned under the “Applications” heading below.

 

How to Use This Transistor:

BC527 is a bipolar junction transistor so the procedure of using the transistor is straightforward. When you are using it as an amplifier then the signal that you want to amplify should be apply to its base pin, the emitter pin should be connected with the positive rail of the circuit and the amplified output will be received at the collector pin but to make a proper circuit you have to use some passive components according to the circuit requirements.

When used as a switch the signal (from which you want to control the output) will be applied to its base pin, emitter pin will be connected with the positive rail of the circuit and the load will be derived through the collector pin. The switch circuit will also require some passive component to function properly.

 

Applications:

Signal Amplification

Audio Preamplifiers

Audio Amplifiers

Sensor Circuits

RF Circuits

Darlington Pairs

Switching loads under 1A

And more…

 

Safe Operating Guidelines:

Do not use the transistor to its absolute maximum ratings and always stay at least 20% to 30% below from its absolute maximum ratings. Always check pinout before using it or placing in a circuit. The using temperature range is -55°C to 150°C.
