2N2222 Metal Can Transistor Explained / Description:
BF495 is an NPN transistor manufactured in TO-92 package. It is a medium frequency transistor designed to use in RF and radio applications. As shown in the above image the first pin of the transistor is base, second is emitter and third is collector. The maximum collector current of the transistor is 30mA which means the transistor can drive maximum load of 30mA, the maximum collector to emitter voltage is 20V which means it can drive load voltage of upto 20V. The total power dissipation of the transistor 300milliwatts, the transition frequency of the transistor is 120MHz and the DC current gain of the transistor is 35 to 125.
Where We Can Use It & How to Use:
As mentioned above BF495 is primarily designed or radio and RF applications and can be used in variety of this type of applications such as High frequency circuits is televisions and radios, FM Radios, AM Oscillators of low noise type, IF amplifiers etc. But it can also be for audio amplification purposes like audio preamplification or audio amplification. Moreover it can be used in any type of general purpose applications.
Applications:
Audio Premamplifier Circuits
Audio Amplifier Circuits
FM Radios
FM Senders
Any general purposes switching and amplification
Replacement and Equivalent:
BF494, 2N9018, C3355, BF199
Safe Operating Guidelines / Absolute Maximum Ratings:
For long term performance of this device it is important to understand its absolute maximum ratings. For safe operations always stay 20% of its absolute maximum ratings. The maximum collector current of the transistor is 30mA therefore do not drive load of more than 24mA. The maximum collector to emitter voltage is 20V therefore do not drive load of more than 16V. Always store of operate the transistor in temperature above -65°C and below +150 °C.
