Electrical Specifications @ +25 ºC (Unless Otherwise Specified)
NOTE 1 The JEDEC type numbers shown above have a standard tolerance of ± 5 % oF the nominal Zener voltage. VZis
measured with the diode in thermal equilibrium at 25 °C ± 3 °C
NOTE 2 VZ@ 100 "A minus VZ @ 10 μA.
NOTE 3 Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
Our passion for performance is defined by three
attributes represented by these three icons:
solution-minded, performance-driven and customer-focused.
