Additional Details:

The P2500SCL features a breakover voltage (VBO) of 250V. When a surge exceeds this voltage, the SIDACtor rapidly switches to a low on-state voltage, diverting the excess current away from protected circuits. This fast response time and low clamping voltage are essential for effective surge protection. The holding current (IH) ensures that the device remains in the on-state for the duration of the surge event.

Littelfuse SIDACtor devices are renowned for their robustness and reliability, making them a popular choice for overvoltage protection in a wide range of applications. The P2500SCL provides dependable protection for electronic systems against voltage transients.
