MMBFJ112
MMBFJ112 is an N-Channel JFET transistor made by ON Semiconductor. With a breakdown voltage of 35 V, it functions in the -55°C to 150°C (TJ) temperature range. The device is appropriate for small and effective electronic applications because it is packaged in a SOT-23-3 supplier device packaging. This part is associated with the MMBFJ1 series.
Description
Overview
MMBFJ112 is manufactured by onsemi. It's an N-channel JFET, which is a type of transistor as well. Among its many attributes are its outstanding fit for holding circuits, chopper stabilized amplifiers, and low-level analog switches. Its drain current is 5 mA at 15 V, while its breakdown voltage is 35 V. Its conduction resistance of 50 ohms and cut-off voltage of 1 V at 1 µ a make it extremely efficient in the intended use. This JFET operates in the temperature range of -55 °C to 150 °C and has a maximum dissipation power of 350 mW. It comes in a small, surface mount SOT-23-3 package that is easy to install in a variety of circuits.
- Main features of the product:
- MMBFJ112 is a highly versatile device. It is designed specifically for applications such as low-level analog switches, sampling and holding circuits, and chopper stabilized amplifiers. It originates from process 51, ensuring high manufacturing standards and consistent performance. And one of its notable features is that the source and drain are interchangeable, providing greater flexibility and convenience in circuit design and integration.
- Electrical and thermal characteristics:
- This product can handle drain gate voltages of up to 35V and gate source voltages of -35V, providing a powerful operating threshold. It supports a forward gate current of up to 50mA. The device operates reliably within the temperature range of -55 ° C to 150 ° C and is suitable for various environmental conditions. However, it is important to note that stress exceeding the absolute maximum rated value may damage the equipment. Therefore, it is not recommended to operate above the specified conditions to maintain equipment reliability.

- Application and durability:
- MMBFJ112's accuracy and stability make it a perfect option for delicate simulation switching operations. Its small SOT-23-3 package is perfect for applications with limited space for it is simple to put on the surface. We advise adhering to the suggested operating settings when using and avoiding extended exposure to stress situations that exceed these limitations in order to guarantee lifetime and consistent performance.
