What it represents
A diode structure used in applications such as RF switching or attenuation with a documented bias circuit.
On a schematic, identify the anode/cathode connection and DC bias path and trace the RF signal route and isolation components. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
The letters PIN describe the semiconductor structure and do not mean a connector pin or digital input.
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 anode/cathode connection and DC bias path.
- Trace the RF signal route and isolation components.
Information to show or reference
- Label the anode/cathode connection and DC bias path.
- Cross-reference the RF signal route and isolation components.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
The letters PIN describe the semiconductor structure and do not mean a connector pin or digital input.
