DESCRIPTION

APPEARANCE

These Microsemi 30 kW Transient Voltage Suppressors (TVSs) are

designed for applications requiring protection of voltage-sensitive electronic

devices that may be damaged by harsh or severe voltage transients

including lightning per IEC61000-4-5 and class levels with various source

impedances described herein. This series is available in 33 to 400 volt

standoff voltages (V_WM) in both unidirectional and bi-directional with either

5% or 10% tolerances of the Breakdown Voltage (V_BR). Microsemi also

offers numerous other TVS products to meet higher or lower power

demands and special applications

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
