1. TOLERANCE AND TYPE NUMBER DESIGNATION  
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.  
2. ZENER VOLTAGE (V ) MEASUREMENT  
Z
ON Semiconductor guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T ) at 30°C ±1°C,  
L
3/8″ from the diode body.  
3. ZENER IMPEDANCE (Z ) DERIVATION  
Z
The zener impedance is derived from 60 seconds AC voltage, which results when an AC current having an rms value equal to 10% of the  
DC zener current (I or I ) is superimposed on I or I .

4. SURGE CURRENT (I ) NON–REPETITIVE  
R
The rating listed in the electrical characteristics table is maximum peak, non–repetitive, reverse surge current of 1/2 square wave or  
equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I , per JEDEC standards. However, actual device  
ZT  
capability is as described in Figure 3 of the General Data sheet for Surmetic 30s.

APPLICATION NOTE  
Since the actual voltage available from a given zener  
diode is temperature dependent, it is necessary to determine  
junction temperature under any set of operating conditions  
in order to calculate its value. The following procedure is  
recommended:  
∆T is the increase in junction temperature above the lead  
temperature and may be found from Figure 2 for a train of  
power pulses (L = 3/8 inch) or from Figure 10 for dc power.  
JL  
∆TJL = θJL PD  
For worst-case design, using expected limits of I , limits  
Z
Lead Temperature, T , should be determined from:  
L
of P and the extremes of T (∆T ) may be estimated.  
D
J
J
TL = θLA PD + TA  
Changes in voltage, V , can then be found from:  
Z
θ
is the lead-to-ambient thermal resistance (°C/W) and P  
D
LA  
∆V = θVZ ∆TJ  
is the power dissipation. The value for θ will vary and  
LA  
θ
, the zener voltage temperature coefficient, is found  
VZ  
depends on the device mounting method. θ is generally  
LA  
from Figures 5 and 6.  
30–40°C/W for the various clips and tie points in common  
use and for printed circuit board wiring.  
Under high power-pulse operation, the zener voltage will  
vary with time and may also be affected significantly by 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.  
The temperature of the lead can also be measured using a  
thermocouple placed on the lead as close as possible to the  
tie point. The thermal mass connected to the tie point is  
normally large enough so that it will not significantly  
respond to heat surges generated in the diode as a result of  
pulsed operation once steady-state conditions are achieved.  
Using the measured value of T , the junction temperature  
L
may be determined by:  
TJ = TL + ∆TJL
