What it represents
A junction field-effect transistor using a P-type channel and the corresponding gate-bias polarity.
On a schematic, identify the gate junction polarity and drain/source references and trace the analogue control or amplifier path. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
P-channel and N-channel JFETs use opposite gate-bias polarity; the arrow and manufacturer terminal diagram resolve the type.
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 junction polarity and drain/source references.
- Trace the analogue control or amplifier path.
Information to show or reference
- Label the gate junction polarity and drain/source references.
- Cross-reference the analogue control or amplifier path.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
P-channel and N-channel JFETs use opposite gate-bias polarity; the arrow and manufacturer terminal diagram resolve the type.
