Additional Details

The EM3000XS GDT is designed for through-hole mounting and is typically used in conjunction with other protection components, such as fuses and transient voltage suppressors (TVS diodes), to provide comprehensive overvoltage protection. The GDT's key parameters include its DC spark-over voltage, impulse spark-over voltage, and surge current rating. It is essential to consult the EPCOS datasheet for detailed specifications and application guidelines to ensure optimal performance in your specific application.

The GDT operates by creating a low-impedance path to ground when the voltage across it exceeds its spark-over voltage. This diverts the surge current away from the protected circuit, preventing damage. After the surge event, the GDT returns to its high-impedance state, allowing normal circuit operation to resume.
