Electrical Specifications: TA = +25°C (unless otherwise specified)
1. Zener voltage tolerance on "A" suffix is +5%. No Suffix denotes +10% tolerance, "C" suffix denotes +2% tolerance and "D" suffix denotes
+1% tolerance.
2. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C.
3. Zener impedance is derived by superimposing on IZT A 60Hz rms a.c. current equal to 10% of IZT

Notes:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension BD shall be measured at the largest diameter.
4. The BL dimension shall include the entire body including slugs.
5. Dimension LU shall include the sections of the lead over which the diameter is uncontrolled. This uncontrolled area is defined as the zone
between the edge of the diode body and extending .050 inch (1.27 mm) onto the leads.
6. In accordance with ASME Y14.5M, diameters are equivalent to Фx symbology.
