DESCRIPTION
APPEARANCE
This high power Transient Voltage Suppressor and Zener is designed for
applications requiring protection of voltage-sensitive electronic devices
that may be damaged by high power or high energy voltage transients
including lightning per IEC61000-4-5 and classes 1-4 with various source
impedances described herein. Individual cells are matched to ensure
current-sharing under high current pulse conditions and for continuous
operation as a Zener when required.

NOTE 1: Rated Standoff Voltage (V ) is defined as normal input voltage to device for non-operating condition. If non-sinusoidal wave or dc
WM
input is present, the peak operating voltage input values for V
should be used to select device type.
WM
NOTE 2: The maximum device clamping factor CF is a ratio of VZ measured at IZ (pulse) given in the Electrical Characteristics Table divided by VZ
measured at IZT under steady state conditions. This value guarantees the sharpness of the voltage breakdown of individual devices.
Figure 2 demonstrates the typical sharpness of the breakdown, and indicates the voltage regulation over a wide range of currents where
the change in voltage êVZ is as follows: êVZ = VZ @ IZ (pulse) – VZ @ IZT
