Protection Mechanism: MOSFET Overheat Auto-Protection

(Effectively prevents damage caused by high temperatures during extended use.)

Additional Notes:

This ignition module adopts dynamic frequency sweeping for automatic arc initiation—no manual triggering required. When paired with the included transformer and powered by 12V, it supports natural cooling for long-term operation.

The heating rate of the MOSFETs depends on the arc gap; a smaller gap results in faster heating.

The high-voltage output wires should not be excessively long. If extension is needed, extend the power supply wires or the transformer secondary instead.

Test Data:

Under extreme test conditions with a constant 12V power supply, the module sustained continuous ignition for 20 minutes in a 10°C environment.

The MOSFET temperature reached approximately 90°C without triggering overheat protection.

The protection is triggered around 100°C.

Testing was done using a precision digital power supply with an 18mm arc gap and the driver board suspended in air.

If using a regular 12V switching power supply, early triggering of overheat protection may occur due to:

•Output voltage exceeding 12V (e.g., 12.2V)

•Voltage instability

•Higher ambient temperatures

In such cases, the protection may trigger after ~2 minutes on first use from a cold start.

Attaching small heatsinks to the 4 MOSFETs on the driver board is a recommended solution.

Compared with similar products, this module’s thermal performance is among the best.

Important Notice:

Due to high power output, the transformer’s secondary high-voltage output terminals must be well insulated to prevent arcing directly at the output pins, which can cause irreversible damage (e.g., burning or breaking the pins).

This is not considered a quality defect, but rather user mishandling.

Before proper insulation is applied, only perform momentary power-on testing.
