PHP500 [Microchip]

The PHP and PIP bidirectional Transient Voltage Suppressor (TVS) modules are designed for applications requiring 'across the line' ac power protection. They are used where extreme voltage transients can permanently damage voltage-sensitive systems or components. These devices are most often used when discrete TVS components do not have sufficient power requirements to suppress high power surges. These modules can be used to protect equipment from induced lightning, power surges, and transients originating from inductive switching or power interrupt for both commercial and military applications. The PHP series features hermetically sealed glass-to-metal packaging for military applications, while the PIP series uses molded epoxy components for commercial applications. Both series offer working RMS voltages from 8.4 to 500 Volts and peak pulse power dissipation of 7,500 or 15,000 Watts.
