30KP22-30KP400
30kW TRANSIENT VOLTAGE SUPPRESSOR
High-reliability discrete products
and engineering services since 1977
FEATURES
Axial and radial available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number
Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix.
Available in both unidirectional and bidirectional construction (bidirectional “C” or “CA” suffix)
Available in both axial-leaded and radial packages (include “R” prefix for radial packages)
