Microsemi’s RT130KP275 and RT130KP295 bidirectional 130 kW

Transient Voltage Suppressors (TVSs) protects 120 volt ac airborne

electronic equipment from harsh lightning per RTCA/DO-160E Section 22

and is compatible with Section 16 for 180 volt ac 100 ms highline surges

(paragraph 16.5.2.3.1b). Microsemi also offers a broad spectrum of other

TVS products to meet your needs.
