 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 because
rust which causes poor solderability would form in each
terminal when stored in high temperature, high humidity
environment.
 Cooling Method
Operating temperature range is specified by the baseplate
temperature. Therefore, several method of heat dissipation
is 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 voltage
of 1.5kVDC between input to baseplate, 1.5kVDC between
input to output, 1.5kVDC between the control terminals to
input/output and 500VDC between output to 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 withstand 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.
Short the output side as shown in the diagram below.

 Insulation Resistance
Use DC insulation tester (MAX 500V) between output
and baseplate. Insulation resistance value is 100MΩ and
above at 500VDC applied voltage. Also take note that de-
pending on the insulation tester used, some testers gener-
ate high voltage pulse. Discharge the power module after
test using a resistor, etc.
 Withstand Vibration
Refer to Application Notes “Mounting Method” section.
 Withstand Shock
Withstand shock value is defined to be the value at Densei
Lambda shipment and packaging conditions.
 Others
The performance of a system with Power Module is in-
fluenced according to various conditions -- PCBs, chas-
sis, mechanics, heat dissipation. Please evaluate actual
products, and confirm its performance. (For details, please
refer Power Module Application Note.)
