What it represents
A junction field-effect transistor using an N-type channel controlled through a gate junction.
On a schematic, identify the gate bias and drain/source connections and trace the analogue switch or amplifier signal path. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A JFET gate is a semiconductor junction, unlike the insulated gate of a MOSFET.
Terminal letters describe electrical roles, not package pin numbers. Check the selected public datasheet for the actual pin assignment, polarity and any internally connected terminals before completing the drawing.
How to read it
- Identify the gate bias and drain/source connections.
- Trace the analogue switch or amplifier signal path.
Information to show or reference
- Label the gate bias and drain/source connections.
- Cross-reference the analogue switch or amplifier signal path.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
A JFET gate is a semiconductor junction, unlike the insulated gate of a MOSFET.
