Flywheel Diode Protection Diagram Explained ⚡🔋

A Flywheel Diode, also called a Freewheeling Diode, is used in circuits with inductive loads like relays, solenoids, or motors to protect the switching components (like transistors) from voltage spikes.

When current flows through an inductor, it stores energy in its magnetic field. If the circuit is suddenly opened, this energy tries to keep the current flowing — creating a high back EMF (electromotive force) that can damage components. The flywheel diode provides a safe path for this current, allowing it to "freewheel" until the energy is safely dissipated.

In the diagram, the diode is connected in parallel with the inductive load but in reverse polarity to the supply. When the switch is on, current flows normally. When the switch turns off, the diode conducts and prevents the voltage spike, protecting the circuit.

👉 Key Points:

Prevents high-voltage damage to switches/transistors.

Used with relays, DC motors, solenoids, and inductive loads.

Ensures longer life and reliability of electronic components.

⚙️ Real-world Example:
Used in relay driver circuits, motor controllers, and automotive electronics to safeguard against inductive kickback.
