DESCRIPTION
APPEARANCE
These Microsemi 15 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 generally available in 22 to
280 volt standoff voltages (VWM) in both unidirectional and bi-directional
offered in two different package designs for axial and radial configurations.
Consult factory for availability of the 17 and 18 Volt devices on a special
order basis. Microsemi also offers numerous other TVS products to meet
CASE 5A
(DO-204AR)
CASE 5R
higher or lower power demands and special applications.
