Description

The P4404QV is a transient voltage suppression module designed to protect military and commercial electronic equipment from overvoltages caused by lightning, power interrupt, inductive load switching, AC line fluctuations, and NEMP. It is part of the PIP & PHP series of TVS modules that find applications in both commercial and military environments. Some common applications include telecommunications, shipboard and aircraft, power distribution, computers, and power supplies. For military applications, the PHP module sub-assemblies are metallurgically bonded and packaged in a hermetically sealed package. TVS modules are used in situations where discrete TVS diodes do not have high enough surge handling capability to suppress large power surges.
