2SC1674 Transistor Explained / Description:

2SC2235 is another interesting TO-92MOD NPN transistor packed with many good features such as high collector-emitter voltage, good collector current, collector power dissipation of 900mW and availability of its complimentary transistor.

Understanding the absolute maximum ratings of the transistor, the absolute maximum ratings means the maximum or last limits of the transistor above these limits the transistor will not survive. So it is always important to drive the transistor at least 20% below from its absolute maximum ratings. Doing this will not put stress on the transistor and also good for the lifespan of the transistor.

Now looking at the absolute maximum ratings of the transistor the collector-emitter voltage is 120V, collector current is 800mA, collector-base voltage is also 120V, emitter-base voltage is 5V, emitter current is -800mA, collector power dissipation is 900mW, junction temperature is 150°C and storage and operating temperature is from -55°C to 150°C.

2SC2235 is available in two different variations according to its DC current gain values and can be identified by alphabets written after its part number. If that alphabet is “O” then that transistor’s DC current gain or hFE will be 80 to 160 and if the alphabet is “Y” then the transistor’s hFE will be 120 to 240.

 

How to Use This Transistor:

2SC2235 is designed to be used audio amplifiers and driver stages of amplifiers. Here we are going to discuss a simple one transistor amplifier using 2SC2235. This simple amplifier is mostly used at the output of musical bell or toys to amplify that audio signal.

For making the circuit connect the emitter pin of the transistor with the negative supply of the circuit, apply signals which you want to amplify to the base of the transistor through an electrolytic capacitor (Using any value from 1uF to 10uF) and the speaker will be connected between the collector pin and the positive rail of the circuit.

 

Applications:

Audio Amplifiers

Audio Amps Driver Stages

RF Circuits

Preamplifier Circuits

Switching applications

Variety of General Other Purpose Applications

 

Safe Operating Guidelines:

Follow these guidelines to safely operate the transistor:

• As discussed above always use the transistor at least 20% below from its absolute maximum ratings.
• The maximum collector-emitter voltage is 120V but according to the above guidelines which suggest to use it at least 20% below from its max ratings we will not drive load of more than 96V.
• The maximum collector current is 800mA but same as above by following the 20% rule we will stay under 640mA, means we will not drive load of more than 640mA.
• Always check pin layout before use.
• The storage and operating temperature should be between -55°C to 150°C.
