Silicon Avalanche Diodes
1500 Watt Axial Leaded Transient Voltage Suppressors
RoHS
1.5KE Series
®
The 1.5KE Series is designed specifically to protect sensitive
electronics equipment from voltage transients induced by
lightning and other transient voltage events. These devices are
ideal for the protection of I/O interfaces, Vcc bus and other
vulnerable circuits used in telecom, computer, industrial and
consumer electronic applications.
