PLAD15KP5.0 thru PLAD15KP400CA, e3
15,000 W SURFACE MOUNT TRANSIENT
VOLTAGE SUPPRESSOR
SCOTTSDALE DIVISION
DESCRIPTION
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
classes with various source impedances described herein. This
series is available in 5.0 to 400 volt standoff voltages (V
WM
) in both
unidirectional and bidirectional offered in one surface mount
device. Microsemi also offers numerous other TVS products to
meet higher and lower power demands and special applications.
