2SC3856 Transistor Explained / Description:
2SC3856 is an NPN transistor manufactured in TO-3PN package. The transistor contains many good features such as high collector-emitter voltage, good collector current, good collector power dissipation, transition frequency of 20MHz, junction and storage temperature of -55°C to 150°C and availability of complimentary transistor.
The transistor is designed to be used in audio and other general purpose applications. Looking at the absolute maximum rating of the transistor the collector-emitter voltage is 180V, connector current is 15A, collector-base voltage is 200V, emitter-base voltage is 6V, base current is 4A, collector power dissipation is 130W and storage and junction temperature is from -55°C to 150°C.
The transistor is available in three different variations according to its DC current gain and can be determined with the help of an alphabet writer after the part number. If that alphabet is “O” then the gain will be 50 to 100, if “P” then the gain will be 70 to 140 and if the alphabet is “Y” then the gain will be 90 to 180.
How to Use This Transistor:
This transistor can be used in general purpose amplifier and switching applications. To use it as a switch connect its emitter pin with the negative rail of the circuit apply signal to the base through a current limiting resistor and drive the load through collector, the negative wire of the load will be the with the collector and the positive wire of the load will be connected with the positive rail of the circuit
Using it as an amplifier is a little complicated as compare to use it as a switch therefore we will discuss a simple amplifier circuit that you have mostly seen in doorbells and other musical devices. To use it as an amplifier connect its emitter pin with the negative rail of the circuit, apply signal that you want to amplify to its base through an electrolytic capacitor and connect a speaker between the collector and the positive rail of the circuit.
Applications:
Audio Amplifiers
Audio Amplifier Stages
DC to DC Converters
Switching Regulators
Battery Management Systems
PWM Circuits
Switching load of up to 15A
Safe Operating Guidelines:
Here are some important guidelines to safely operate the transistor.
- Always use the transistor atleast 20% below from its absolute maximum ratings.
- Check pin layout of the transistor before use.
- Using a heatsink with the transistor is essential.
- Storage and operating temperature should be between -55°C to +150°C.
