Additional Details:

The P2600SBL has a breakover voltage (VBO) of 260V. When a surge exceeds this voltage, it quickly switches to a low on-state voltage, diverting the surge current away from sensitive components. The device's low clamping voltage ensures the voltage across the protected circuit remains within safe operating limits. The holding current (IH) is specified to ensure the device remains in the on-state during the entire duration of the surge event. The P2600SBL is suitable for applications where reliable surge protection is critical.

Littelfuse SIDACtor devices are known for their high reliability and performance, making them a popular choice for protecting electronic equipment in various applications. The P2600SBL provides a robust and effective solution for protecting against overvoltage transients.
