描述 Description

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. This includes telecommunications, central office switching and PABX, CATV distribution, aircraft, shipboard, computers, distributed data processing and power supplies. The subassembly components can also be tested or screened for military requirements prior to encapsulation into the complete module. The screening would consist of 100% TX level environmental testing per MIL-PRF-19500/507A (Par. 4.3). For ordering these options, use the following suffix:H1 ? Submodule ScreeningH2 ? Submodule and Module ScreeningH3 ? Submodule and Module Screening & Module Group B & C lot testing

特性 Features

Designed for Military (PHP Series) and Commercial (PIP Series)
Working rms voltages (VWM(RMS)) available in ranges from 8.4 to 500 Volts
For military applications, the PHP module subassemblies are packaged in a hermetically sealed glass-to-metal package and are also optionally screened in accordance with MIL-PRF-19500/507.
The PHP series modules can also have design consistency with the following military controlling specifications: MIL-STD-1399, Section 300
MIL-STD-704
MIL-E-16400
