2SC1008 Transistor Explained / Description:

2SC1008 also called C1008 available in TO-92 package is an NPN transistor designed to be used in general purpose amplifier and switching applications. The transistor has many good features which are good collector current, high collector-emitter voltage, good DC current gain and high collector power dissipation. All these features make this transistor capable to work in wide variety of applications.

The absolute maximum ratings of the transistor are as follows: collector current of 700mA, collector-emitter voltage is 60V, collector-base voltage is 80V, emitter-base voltage is 8V, collector power dissipation is 800mW, junction temperature is 150 ̊C, and storage and operating temperature is from -55 ̊C to +150 ̊C.

The DC current gain of the transistor is from 40 to 400 but it is available in four different variations according to its DC current gain and can be identified by looking at the alphabet writing after the part number. If that alphabet is “R” then hFE will be 40 to 80, if the alphabet is “O” then 70 to 140, if it is “Y” then 120 to 240 and if “G” then its hFE will be 200 to 400.

 

How to Use This Transistor:

Here’s how to use the transistor as a switch and amplifier. Wiring a transistor as a switch is easy but wiring it as an amplifier is not easy however we will discuss a simple amplifier circuit to understand how to use it as an amplifier.

To use it as a switch connect the emitter pin with the negative rail of the circuit, apply signal to its base through a current liming resistor (the signals through which you want to drive the load). A current limiting resistor can be from 1K to 10K. The load will be connected between collector and the positive rail of the circuit.

For making an amplifier you have to connect it in active region for doing so make a voltage divider by connecting two resistors from its base to positive and negative rail of the circuit. Apply signals which you want to amplify through an electrolytic capacitor between 1uF to 10uF value. The emitter pin will be connected with the negative rail of the circuit and the amplified audio will be received at the collector pin of the transistor.

 

Applications:

Switching Circuits

Audio Preamplifier Circuits

Audio Amplifier Circuits

Audio Amplifier Stages

Safe Operating Guidelines:

Follow these guidelines to safely operate the transistor:

• Do not operate the transistor to its absolute maximum ratings and stay at least 20% below to its max ratings.
• Always check pin configuration before using it.
• The storage and operating temperature should be from -55°C to 150°C.
