 Operating Ambient Humidity
Take note that moisture could lead to power module ab-
normal operation or damage.
 Storage Ambient Temperature
Abrupt temperature change would cause moisture forma-
tion that leads to poor solderability of each terminal of the
power module.
 Storage Ambient Humidity
Take enough care when storing the power module be-
cause rust which causes poor solderability would form in
each terminal when stored in high temperature, high hu-
midity environment.
 Cooling Method
Operating temperature range is specified by the baseplate
temperature. Therefore, several methods of heat dissipa-
tion are possible.
For details on thermal design, refer to Application Notes
 Baseplate Temperature vs. Output Voltage Drift
Output voltage drift is defined as the rate of voltage
change when baseplate temperature only is changed dur-
ing operation.
 Withstand Voltage
This power module is designed to have a withstand volt-
age of 1.5kVDC between input and baseplate, 1.5kVDC
between input and output and 500VDC between output
and baseplate for 1 minute. When conducting withstand
voltage test during incoming inspection, be sure to apply
DC voltage. Also, set the current limit value of the with-
stand voltage testing equipment to 10mA.
Be sure to avoid conducting test with AC voltage because
this would cause power module damage.
Furthermore, avoid throw in or shut off of the testing equip-
ment when applying or when shutting down the test volt-
age. Instead, gradually increase or decrease the applied
voltage. Take note especially not to use the timer of the
test equipment because when the timer switches the ap-
plied voltage off, impulse voltage which has several times
the magnitude of the applied voltage is generated causing
damage to the power module.
Connect the terminals as shown in the diagram below.

 Isolation Resistance
Use DC isolation tester (MAX 500V) between output and
baseplate. Isolation resistance value is 100MΩ and above
at 500VDC applied voltage. Also take note that depending
on the isolation tester used, some testers generate high
voltage pulse. Discharge the power module after test using
a resistor, etc.
 Vibration
Vibration of power module is defined in case of mounting
on printed circuit board.
 Shock
Withstand shock value is defined to be the value at Den-
sei -Lambda shipment and packaging conditions.

Please refer to "Power Module Application Note" for ther-
mal design and mounting direction.
