Semiconductors
Diodes, transistors and thyristors, with the behaviour of each.
Most semiconductors have a model you can edit from their properties, for example the diode's forward voltage.
Diodes
| Part | Behaviour |
|---|---|
| Diode | Conducts one way (anode to cathode). |
| Zener | Conducts backwards at its zener voltage. Used for regulation. |
| Varactor | A diode whose capacitance changes with voltage. |
| Tunnel diode | A diode with a region of negative resistance. |
Transistors
| Part | Behaviour |
|---|---|
| NPN and PNP | Bipolar transistors. A small base current controls a larger collector current. |
| NPN Darlington and PNP Darlington | Two transistors in one for very high gain. |
| N-MOSFET and P-MOSFET | Voltage-controlled switches and amplifiers. |
| N-JFET and P-JFET | Junction field-effect transistors. |
| UJT | Unijunction transistor, used in oscillators. |
Thyristors and others
| Part | Behaviour |
|---|---|
| SCR | Turns on with a gate pulse and stays on until the current stops. |
| DIAC | A two-terminal part that conducts above a breakdown voltage. |
| TRIAC | An AC switch triggered by a gate. |
| Triode | A vacuum tube. |
