FOR
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 (VWM) in both unidirectional and bi-directional with either
5% or 10% tolerances of the Breakdown Voltage (VBR). Microsemi also
offers numerous other TVS products to meet higher or lower power
demands and special applications.
