2. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)  
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.  
3. ZENER VOLTAGE (VZ) MEASUREMENT  
Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (TL) at 30°C  
±1°C and 3/8” lead length.  
4. ZENER IMPEDANCE (ZZ) DERIVATION  
ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits  
are for IZ(AC) = 0.1 IZ(DC) with AC frequency = 60Hz.  
5. MAXIMUM ZENER CURRENT RATINGS (IZM  
)
Values shown are based on the JEDEC rating of 400mW where the actual zener voltage (VZ) is known at the operating  
point, the zener current may be increased and is limited by the derating curve.

APPLICATION NOTE - ZENER VOLTAGE  
500  
400  
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:  
L
L
300  
200  
100  
Lead Temperature, TL, should be determined from:  
2.4-60 V  
TL = θLAPD + TA.  
θLA is the lead-to-ambient thermal resistance (°C/W) and PD  
is the power dissipation. The value for θLA will vary and  
depends on the device mounting method. θLA is generally 30  
to 40°C/W for the various clips and tie points in common use  
and for printed circuit board wiring.

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 TL, the junction temperature  
may be determined by:  
L , LEAD LENGTH TO HEAT SINK (INCH)

BREAKDOWN VOLTAGE  
TJ = TL + ∆TJL.  
700  
500  
∆TJL is the increase in junction temperature above the lead  
temperature and may be found from Figure 2 for dc power:  
200  
100  
70  
∆TJL = θJLPD.  
50  
For worst-case design, using expected limits of IZ, limits  
of PD and the extremes of TJ(∆TJ) may be estimated.  
Changes in voltage, VZ, can then be found from:  
20  
10  
∆V = θVZTJ.

θVZ, the zener voltage temperature coefficient, is found  
from Figures 4 and 5.

0.7  
0.5  
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.  
+125°C  
0.2  
Surge limitations are given in Figure 7. 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 7 be exceeded.
