The maximum continuous gate current is 50mA so do not drive load of more than 40mA and always store or operate the transistor at temperature above -55☌ and below +150 ☌. The maximum drain to gate voltage is 35V therefore do not drive load of more than 28V. Therefore same applies to J111 transistor. It is always recommended to check absolute maximum ratings of the transistor before using in your design or circuit and we also suggest to not use a component on its absolute maximum ratings and always stay atlest 20% below from the absolute max ratings. Safe Operating Guidelines / Absolute Maximum Ratings: Low level signal amplification applications If you need a fast switching transistor with low leakage and low capacitance, then the J111 is a good choice. When we look at the specs of the transistor the maximum drain to gate voltage is 35V, maximum continuous gate current is 50mA, maximum reverse gate to source voltage is -35V, max gate to source cutoff voltage is -0.5 to 3V and the max power dissipation is 625mW.Īs mentioned above that J111 FET or field effect transistor is primarily designed for current limiting, analog switching, choppers, commentators and sample and hold applications but J111 transistor is a versatile device that can be used in a variety of applications. The transistor also has Symmetrical features which means the drain and source of the transistor are interchangeable. Moreover the transistor also has low noise feature which means it can be used in applications where the user also has low noise requirements. There are also many benefits of using these transistors in your design such as they provide better response to frequency, they have good accuracy, low insertion loss and they are also low cost. All the transistors in this series are primarily built to use for analog switching applications, current limiting, choppers, commentators and sample and hold applications. J111 is a transistor from J11x series, this series also contains J112 and J113 transistors. J111 is an N channel silicon field effect transistor available in TO-92 and SOT-23 packages. Max Storage & Operating temperature Should Be: -55 to +150 ☌ĢN4416, J201, j202, j203, NTE312, NTE458, 2N4340, 2N4341 are the nearest possible substitute of J112 but they may not have symmetrical feature.
