Additional Details:

The TISP61511D-S typically features a breakover voltage around 11V, providing overvoltage protection for equipment operating at lower voltage levels. Always refer to the datasheet for precise technical specifications. As a thyristor, it switches to a low-impedance state when the voltage exceeds its breakover voltage, diverting the surge current away from protected circuitry. Key parameters to consider during circuit design include holding current and on-state voltage, which affect the device's operation and reset characteristics following a surge event. Its surface-mount design enables efficient assembly and space utilization in various applications.
