704-15K36 and 704-15K36T TRANSIENT VOLTAGE SUPPRESSOR SCOTTSDALE DIVISION APPEARANCE 7 704-15K367 WWW . Microsemi .C OM DESCRIPTION These two modularized unidirectional TVS products are primarily used in avionics or other demanding applications for transient voltage protection. They meet all applicable environmental requirements of MIL-PRF-19500 and may be used for both commercial and military applications. The controlling specification for these devices is MIL-STD-704 (Characteristics and Utilization of Aircraft Electric Power) where these 15 kW assemblies are designed typically to operate with a low source impedance of 0.25 Ohms for transients to protect equipment from induced lightning, power surges, and transients originating from inductive switching or power interrupt. 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-PRF19500/500 (Par. 4.3). For ordering these options, use the following suffix: H1 - Submodule Screening H2 - Submodule and Module Screening H3 - Submodule and Module Screening & Module Group B & C lot testing 704-15K36T IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com FEATURES * * * * * APPLICATIONS / BENEFITS * * * Designed for military or commercial applications Can be optionally supplied with JANTX subassemblies in accordance per MIL-PRF19500/500.
