JFET N-CH 30V 100MA TO92
Hello everyone, I am Rose. Today we will have a discussion about BF245. BF245 is an N-channel silicon field-effect transistors available in TO-92 package. This article mainly introduce replacement, pinout, datasheet and other detailed information about On Semiconductor BF245.
BF245B
BF245 is an N-channel silicon field-effect transistor available in TO-92 package. It is mainly designed to use as an amplifier in the VHF and UHF frequency bands and also as an audio frequency amplifier.
The transistor possesses high gain and low noise capabilities due to which it will perform well to amplify a very small and low gain signal (RF, Audio, or any other signal) to high gain with unwanted noise filtration.
These devices are manufactured in four different types which are BF245, BF245A, BF245B, and BF245C each type is slightly different from the other in Gate-Source voltage and Zero-Gate Voltage Drain Current.
