Additional Details:

The TISP61511DR features a breakover voltage around 11V, offering protection for sensitive equipment operating at lower voltages. It's important to consult the datasheet to confirm all technical specifications for this specific part number. The thyristor operates by switching to a low-impedance state when the voltage exceeds its breakover voltage, diverting the surge current away from protected components. Consider parameters like holding current and on-state voltage when integrating the TISP61511DR into a circuit to ensure proper operation and reset behavior after a surge event. Its compact size and surface-mount design make it suitable for a variety of applications where space is a constraint.
