p-Channel JFET Linear Region Calculator

p-Channel JFET Linear Region Calculator

Calculate the output (drain) current of a p-channel JFET in the linear region.

Step 1: Enter JFET Parameters

Example: \(5 \times 10^{-3}\) A

Enter as a positive value (for p-channel, this represents \(|V_P|\))

Example: 4 V

Example: 0.5 V (small value in linear region)

Linear Region Current: $$ I_D = \frac{2I_{DSS}}{V_P^2}\left[(V_{SG} – V_P)V_{SD} – \frac{V_{SD}^2}{2}\right] $$

(For p-channel JFET, use \(V_{SG}\) and a positive \(V_P\))
