To Download the datasheet just copy and paste the below link in your browser. Do not drive load of more than 25V and 10mA, do not apply reverse gate to source voltage of more than -25V and always store or operate this transistor in temperature above -65 centigrade and below +150 centigrade.
This same method will apply to MPF102 transistor. To get long term stability of a component in a circuit it is recommended to always stay 20% below the max ratings. It can also be used as a switch but it can drive load of only 10mA.įor a good circuit design it is always essential to use all the components without giving them stress or don’t use them on their maximum ratings. MPF102 can be used in variety of amplification applications it can be used in signal booster circuits, audio preamplifier circuits, audio amplifier stages etc. But if you can’t find it then you can also use its substitute transistors shown above. N-Channel RF Amplifier: This device is designed primarily for electronic switching applications such as low On Resistance analog switching. Gate: This terminal is used to control the biassing of the N-channel JFET. The pin diagram of MPF102 N-channel JFET is shown in the figure below. Although the transistor is not available any more now a days but some suppliers still having them in their stock and you can find it by searching with some reputable components suppliers. The MPF102 N-channel JFET is a 3-pin/terminal voltage-controlled FET available in the TO-92-3 package used in amplifier applications and general-purpose applications. It can also be used for switching purposes. The transistor possesses high gain and low noise features which make it ideal to use for very small or low level signals amplification whether it is an RF signal, audio signal or other. But other than that it can also be used in verity of other audio amplification related applications. The company was established in 1970 and was headquartered in Osaka, Japan. It is mainly built for the amplification in VHF region of frequencies. Sanyo Semicon Device was a manufacturer of semiconductor devices, including diodes, transistors, and other components for consumer electronics, automotive, and industrial applications. MPF102 is a very famous JFET transistor used in many commercial devices as well as educational and hobby projects. MPF102 Transistor Explained / Description: Other nearest Possible numbers are 2N4416, NTE312, 2N5638, 2N5640, 2SK162, 2SK518 (Pin configuration of some transistors mentioned here may different from MPF102 therefore check pin configuration before replacing in a circuit.) Max Storage & Operating temperature Should Be: -65 to +150 Centigrade.Minimum to Maximum Gate to Source Cuttoff Voltage : -8.0.Max Reverse Gate to Source Voltage is: – 25V.Max Drain to Gate Voltage Should Be: 25V The pinout for the MPF102 is shown below: If you deal with BJTs often, it's easy to get into the habit of thinking that the middle pin is the gate, like for a BJT, the middle pin is normally the base, but many times for FETs, this is not the case.Max Voltage Applied From Drain to Source: 25V.
