Additional Details

The PMMAD1108 typically has a standoff voltage (Vrwm) rating that corresponds to the normal operating voltage of the protected circuit. Its clamping voltage (Vc) indicates the maximum voltage that the device will allow to pass through during a transient event. The device's capacitance is a key parameter for high-speed data applications, where low capacitance is crucial to maintain signal integrity. The PMMAD1108 is available in surface-mount packages for automated assembly. Refer to the datasheet for specific electrical characteristics, package dimensions, and application guidelines.
