2SC1841Transistor Explained / Description:
Here is another interesting transistor available in small TO-92 package. The transistor contains some good features such as high collector-emitter voltage, high DC current gain, good transition frequency etc.
Looking at the absolute maximum ratings of the transistor the collector-emitter voltage is 120V, collector current is 50mA, collector-base voltage is also 120V, emitter to base voltage is 5V, base current is 10mA, junction temperature is +125°C and storage temperature is from -55°C to 150°C.
2SC1841 is available in four different variations according to its DC current gain or hFE value and each one can be identified with the help of the alphabet written after the part number. So if that alphabet is “P” then the transistor’s hFE value will be 200 to 400, if the alphabet is “F” then the hFE value will be 300 to 600, if “E” then 400 to 800 and if the alphabet is “U” then its hFE value will be 600 to 1200.
How to Use This Transistor:
It is an NPN bipolar junction transistor which contains three pins that are emitter, base and collector. Here is a simple procedure to understand how to use this transistor. To use the transistor the emitter pin of the transistor will be connected with the negative rail of the circuit. The signal that you want to amplify will be provided at the base of the transistor and the output will be received at the collector pin of the transistor in amplifier circuits but in a switch circuit the load will be derived through the collector. Of course you have to use some passive components you build a better circuit that performs better. For doing so, some knowledge of electronics is required.
Applications:
Audio amplifiers
Audio preamplifiers
Radio and RF Applications
Switching Circuits
Low Gain Signal Amplification
Safe Operating Guidelines:
To safely use the transistor it is always recommended to not use the transistor to its absolute maximum ratings and always stay atleast 20% below from its absolute maximum ratings. Always check its pin layout before using or placing in a circuit and always store or operate it at temperatures above -55°C and below +150 °C.
