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 available in 17 to 280 volt
standoff voltages (VWM) in both unidirectional and bi-directional offered in
two different package designs for axial and radial configurations.
Microsemi also offers numerous other TVS products to meet higher or
lower power demands and special applications.
CASE 5A
(DO-204AR)
CASE 5R

FEATURES
APPLICATIONS / BENEFITS
Available in both Unidirectional and Bidirectional
construction (Bidirectional with C or CA suffix)
Available in both axial-leaded and radial packages
(include R prefix in part number for radial package option
shown in figure as “case 5R,” e.g. R15KP17A)
Selections for 17 to 280 volt standoff voltages (VWM)
Suppresses transients up to 15 kW @ 10/1000 s and
100 kW @ 8/20 s (see Figure 1)
Optional 100% screening for avionics grade is available
by adding MA prefix to part number for added 100%
temperature cycle -55
oC to +125oC (10X) as well as surge
(3X) and 24 hours HTRB with post test VZ & IR (in the
operating direction for unidirectional or both directions for
bidirectional)
Options for screening in accordance with MIL-PRF-19500
for JAN, JANTX, JANTXV, and JANS are also available
by adding MQ, MX, MV, or MSP prefixes respectively to
part numbers.
Moisture classification is Level 1 with no dry pack required
per IPC/JEDEC J-STD-020B
RoHS Compliant devices available by adding “e3” suffix
