NOTE:
1. TOLERANCE AND VOLTAGE DESIGNATION - The JEDEC type numbers shown indicate a tolerance of +- 10% with
guaranteed limits on only Vz, I
R
, I

, and V
F
as shown in the electrical characteristics table. Units with guaranteed
limits on all seven parameters are indicated by suffix "B" for +-5% tolerance.
2. ZENER VOLTAGE (Vz) AND IMPEDANCE (Z

) - Test conditions for Zener voltage and impedance are as
follows; Iz is applied 40 10 ms prior to reading. Mounting contacts are located from the inside edge of mounting
clips to the body of the diode.

Data of Figure 3 should not be used to compute surge capability. Surge limitations are given in Figure 5. 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. 5 be
exceeded
