Electrical Specifications @ +25 ºC (Unless Otherwise Specified)
NOTE 1: Zener voltage tolerance on "A" suffix is +5%. No Suffix denotes +10% tolerance,
"C" suffix denotes +2% tollerance and "D" suffix denotes +1% tolerance.
NOTE 2: Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
NOTE 3: Zener impedance is derived by superimposing on IZT A 60Hz rms a.c. current equal to 10% of IZT
Our passion for performance is defined by three
attributes represented by these three icons:
solution-minded, performance-driven and customer-focused.
