Stay tuned for our next blog… Component Datasheet If you find this blog useful, please bookmark our website Apogeeweb, we will provide you with electronic component blogs, industry news, tools, etc. That’s all for our introduction to 2N5457. 2N5457 works up to 0.005A of continuous draining current (ID). Choose a JFET that can tolerate more than the Drain current that is actually required for the application. 2N5457 supports 25V Drain-Source Break voltage and-25V Gate-Source Breakdown voltage.ģ. Choose a JFET with a Drain-Source and Gate-Source breakdown voltage more than is actually required. Calculate the maximum Drain-Source voltage and the Gate-Source voltage for the targeted application. ![]() If the application requires high side switching, use P-Channel.Ģ. 2N5457 is an N-Channel JFET so it is suitable for use on the low side of the power path. Choose the type of JFET required for the application. This JFET is useful for switching related applications as well. The graph below is a common source transfer graph, useful to know the common source transfer characteristic of JFET. It is suitable for general purpose amplification and switching related applications. R1 and R2 are used as a voltage divider for biasing the JFET.Ī typical value for 12V operation could be, R1 = 100k, R2 = 10k, RC = 10k, and C1, C2 can be 1uF ceramic capacitors. The RC is the collector Resistor and changing this value will change the frequency response of the circuit as well as it will control the DC gain by controlling the collector current. ![]() The C1 is the coupling capacitor and the C2 is the DC blocking capacitor where the output will be harvested. The below image is showing the standard application of the N-Channel JFET 2N5457 as an amplifier. ![]() Note: You can find complete technical details in 2N5457 Datasheet at the bottom of this page. Gate-Source Cutoff Voltage - VGS (off) = -6.0 Vdc (VDS = 15 Vdc, ID = 10 nAdc).Don't konw what is JFETs? There's an introduction video ![]()
