Additional Details:

The TISP7038DR typically features a breakover voltage around 38V. It is crucial to consult the datasheet for specific design requirements. This thyristor acts as a voltage-triggered switch, rapidly transitioning to a low-impedance state when the voltage exceeds the breakover voltage, diverting the surge current away from the protected circuitry. The device's holding current and on-state voltage are important parameters to consider during circuit design to ensure proper operation and reset after the surge has subsided. The DR package typically indicates a specific lead form or mounting configuration, so confirm this detail in the datasheet.
