- Description:
- This is an N-Channel JFET (Junction Field-Effect Transistor) with the part number MMBFJ201. It comes
- pre-soldered on a TO92 adapter board, making it easier to connect to your PCB. This version is the closest
- you can get to the older Fairchild/ON Semiconductor J201, as the through-hole version is difficult to find.
The -40V InterFET J201 and J202 are targeted for sensitive amplifier stages for mid-frequencies
designs. Gate leakages are typically less than 10pA at room temperatures
Features
●InterFET N0016SH Geometry
Low Noise: 5 nV/VHz Typical
Low Ciss: 4pF Typical
●RoHS Compliant
●SMT, TH, and Bare Die Package options.
Applications
●Audio Amplifiers
●Small Signal Amplifier
●Ultrahigh Impedance Pre-Amplifier
The Fairchild J201 is a popular N-channel JFET (Junction Field-Effect Transistor) primarily used in audio applications.
It is widely used for amplification and switching purposes due to its low noise characteristics and high input impedance.
Type: N-channel JFET
-
Pin Configuration: The J201 typically comes in a TO-92 package with three pins: Gate (G), Drain (D), and Source (S).
-
Maximum Ratings: The maximum ratings for the J201 may vary slightly depending on the manufacturer, but typical
-
values are as follows:
- Drain-Source Voltage (VDS): 25V
- Gate-Source Voltage (VGS): -25V
- Drain Current (ID): 50mA
- Power Dissipation (PD): 350mW
- Operating Temperature Range: -55°C to +150°C
-
Electrical Characteristics: The J201 has the following electrical characteristics (typical values):
- Gate-Source Cutoff Voltage (VGS(off)): -0.3V to -6V
- Gate-Source Breakdown Voltage (BVGS): -25V
- Drain-Source Breakdown Voltage (BVDS): -40V to -50V
- Drain-Source Saturation Current (IDSS): 1mA to 20mA
- Forward Transconductance (gm): 1.5mS to 6mS
The Fairchild J201 is commonly used in audio preamplifiers, guitar effects pedals, and other low-power analog
audio applications. It is valued for its low noise performance and ability to work well with high-impedance signal
sources. However, please note that the Fairchild J201 has been discontinued by the manufacturer.
