Additional Details:

The P2500SBL features a breakover voltage (VBO) of 250V. It rapidly switches to a low on-state voltage when a surge exceeds this level, diverting the excess current away from protected circuits. This fast response time and low clamping voltage are critical for effective surge protection. The holding current (IH) is specified to ensure the device remains in the on-state for the duration of the surge event.

Littelfuse SIDACtor devices are known for their robustness and reliability, making them a popular choice for overvoltage protection. The P2500SBL is a dependable component for safeguarding electronic systems against voltage transients in various applications.
