PLAD30KP10 thru PLAD30KP400CA, e3
30kW Surface Mount Transient
Voltage Suppressor
SCOTTSDALE DIVISION
DESCRIPTION
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 10 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.
