Zener voltage is measured with the zener current applied for PW = 1.0 ms.  
All part numbers shown indicate a V tolerance of ±5%.  
Z
Z

with the AC frequency = 1 kHz.  
The zener impedance, Z , for the 27 through 75 volt types is tested at 0.5 mA rather than the test current of 0.1 mA used for V

SURFACE MOUNT APPLICATIONS  
Surface mount board layout is a critical portion of the total  
design. The footprint for the semiconductor packages must be  
the correct size to ensure proper solder connection interface  
between the board and the package.  
1.22  
0.048  
The minimum recommended footprint for the SOD-123 is  
shown at the right.  
The SOD-123 package can be used on existing surface  
mount boards which have been designed for the leadless 34  
package style. The footprint compatibility makes conversion  
from leadless 34 to SOD-123 straightforward.

SOD-123 POWER DISSIPATION  
The power dissipation of the SOD-123 is a function of the  
pad size. This can vary from the minimum pad size for  
soldering to a pad size given for maximum power dissipation.  
Power dissipation for a surface mount device is determined by  
ratings table on the data sheet. Substituting these values into  
the equation for an ambient temperature T of 25°C, one can  
A
calculate the power dissipation of the device which in this case  
is 0.37 watts.

The 340°C/W for the SOD-123 package assumes using  
recommended footprint shown on FR-4 glass epoxy printed  
circuit board. Another alternative is to use a ceramic substrate  
or an aluminum core board such as Thermal Clad . By using  
an aluminum core board material such as Thermal Clad, the  
power dissipation can be doubled using the same footprint.

GENERAL SOLDERING PRECAUTIONS  
The melting temperature of solder is higher than the rated  
temperature of the device. When the entire device is heated  
to a high temperature, failure to complete soldering within a  
short time could result in device failure. Therefore, the  
following items should always be observed in order to  
minimize the thermal stress to which the devices are  
subjected.  
• Always preheat the device.  
• The delta temperature between the preheat and soldering  
should be 100°C or less.*  
• When preheating and soldering, the temperature of the  
leads and the case must not exceed the maximum  
temperature ratings as shown on the data sheet. When  
using infrared heating with the reflow soldering method,  
the difference shall be a maximum of 10°C.  
• The soldering temperature and time shall not exceed  
260°C for more than 10 seconds.  
• When shifting from preheating to soldering, the maximum  
temperature gradient shall be 5°C or less.  
• After soldering has been completed, the device should be  
allowed to cool naturally for at least three minutes.  
Gradual cooling should be used as the use of forced  
cooling will increase the temperature gradient and result  
in latent failure due to mechanical stress.  
• Mechanical stress or shock should not be applied during  
cooling  
* Soldering a device without preheating can cause excessive  
thermal shock and stress which can result in damage to the  
device.
