When a transient overvoltage occurs\u2014exceeding the SPD’s voltage protection level\u2014the protective elements within the device undergo a rapid transition from high-impedance to low-impedance state. This transition occurs in nanoseconds, typically within 25 ns for modern metal oxide varistor (MOV) based devices. The speed of this response is critical because surge events have extremely fast rise times, often reaching peak values in less than 1 microsecond.<\/p>\n\n\n\n

As surge current flows through the SPD, the energy is dissipated primarily as heat within the protective elements. High-quality DC SPDs incorporate thermal management features including heat sinks, thermal coupling to mounting rails, and temperature-monitoring circuits. The energy dissipation capability is characterized by the device’s energy rating, typically expressed in kilojoules (kJ), which must exceed the expected surge energy in the application.<\/p>\n\n\n\n
