GLASS PASSIVATED JUNCTION SILICON ZENER DIODE

Transys Electronics 

For worst-case design, using expected limits of Iz, limits

of PD and the extremes of TJ ( TJL ) may be estimated.

Changes in voltage, Vz, can then be found from:

V = VZ TJ

VZ , the zener voltage temperature coefficient, is

found from Figures 5 and 6.

Under high power-pulse operation, the zener voltage

will vary with time and may also be affected significantly

be the zener resistance. For best regulation, keep current

excursions as low as possible.

Data of Figure 2 should not be used to compute surge

capability. Surge limitations are given in Figure 3. They

are lower than would be expected by considering only

junction temperature, as current crowding effects cause

temperatures to be extremely high in small spots

resulting in device degradation should the limits of Figure

3 be exceeded.
