DO-214AA/ P Series are low capacitance devices designed to protect broadband equipment such as VOIP, DSL modems and DSLAMs from damaging overvoltage transients. The series provides a surface mount solution that enables equipment to comply with global regulatory standards while limiting the impact to broadband signals.

Compared to surge suppression using other technologies, P Series devices offer absolute surge protection regardless of the surge current available and the rate of applied voltage (dv/dt). P Series devices:
1. Cannot be damaged by voltage
2. Eliminate hysteresis and heat dissipation typically found with clamping devices
3. Eliminate voltage overshoot caused by fast-rising transients
4. Are non-degenerative
5. Will not fatigue
6. Have low capacitance, making them ideal for high-speed transmission equipment
