Description
The Power Diode is a Power Component that can be attached to the Power Bus. The diode functions like a one-way valve, allowing current to flow in one direction while blocking it in the opposite direction. This is essential for protecting circuits from reverse current and implementing various power control mechanisms.
Example Use Cases
- Circuit Protection: Prevent reverse current flow that could damage sensitive components
- Voltage Regulation: Used in combination with other components to regulate voltage levels
Module Implementation
The Diode component implements a general model for semiconductor diodes and includes parameters for forward and reverse bias conditions, junction capacitance, and other physical characteristics that affect diode performance.
NOTE
The diode component provides similar functionality to the
Is Forward Biasedproperty on power sources.
Configurable Parameters
The Diode component offers the following configurable parameters:
| Parameter | Description | Unit |
|---|---|---|
| Saturation Current (IS) | Reverse leakage current | A |
| Emission Coefficient (N) | Ideality factor | - |
| Junction Capacitance (CJO) | Zero-bias junction capacitance | F |
| Junction Potential (VJ) | Built-in junction potential | V |
| Grading Coefficient (M) | Junction grading coefficient | - |
| Bandgap Voltage (EG) | Energy gap | V |
| Breakdown Voltage (BV) | Reverse breakdown voltage | V |
| Breakdown Current (IBV) | Current at reverse breakdown voltage | A |
Advanced Parameters
These parameters offer fine control over the diode model but are typically only needed for specialized applications:
| Advanced Parameter | Description | Unit |
|---|---|---|
| Transit Time (TT) | Transit time for carriers crossing junction | s |
| Flicker Noise Coefficient (KF) | Flicker noise coefficient | - |
| Flicker Noise Exponent (AF) | Flicker noise exponent | - |
| Forward-bias Depletion Capacitance Coefficient (FC) | Coefficient for capacitance formula | - |
Assumptions/Limitations
- The diode model assumes operation within standard temperature ranges unless otherwise specified.
