BC528 Transistor Explained / Description:

BC528 is a PNP transistor available in TO-92 package. It is the transistor of a two transistor series and the other one is BC527. Both of these transistors are almost similar the only difference they have is their collector-emitter voltage and BC528 has a 20V more collector-emitter voltage than BC527.

Looking at the absolute maximum ratings of the transistor, the collector-base voltage is 80V, collector current is 80V, collector-emitter voltage is also 80V, emitter-base voltage is 6V, total power dissipation is 625mW and junction & storage temperature is from -55°C to 150°C.

The transistor has many good features such as high collector-emitter voltage, good collector current, upto 100MHz transition frequency, max DC current gain of up to 400 and availability of its NPN complimentary transistor.

All its features and electrical characteristics make it an ideal transistor to use in wide variety of applications.

BC528 comes in 4 different DC current gain values and you can identified or differentiate them according to their DC current gain values very easily. There is a code written after the part number from which you can easily identify the DC current gain value of any BC528 transistor. Here are the codes and their DC current gain values.

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

 

How to Use This Transistor:

The transistor has three pins which are emitter, base and collector. There are many types of circuits you can build with a transistor but here we are discussing only two first is amplifier circuit and the other is switch circuit.  The base pin is where you will provide the signal whether it’s an amplifier circuit or a switch circuit, the emitter pin should be connected with the positive rail of the circuit and the collector pin is where you will receive the final output. If you are building an amplifier circuit then the amplified output will be received at the collector pin and if you have built a switch circuit than the load will be derived with collector. But to build a proper circuit of amplifier or switch you will also require some passive components and some knowledge of electronics and experience.

 

Applications:

Sensor Circuits

RF Circuits

Signal Amplification

Audio Preamplifiers

Darlington Pairs

Audio Amplifiers

Switching loads under 1A

And more…

 

Safe Operating Guidelines:

Always use the transistor under its absolute maximum ratings and stay at least 20% to 30% from these ratings. The operating and storage temperature of the transistor should be between -55°C to 150°C.
