Over Temperature Protection The JNW350R module provides with non-latching over temperature protection. A temperature sensor monitors the operating temperature of the converter. If the reference temperature exceeds a threshold of 110 ºC typical at the center of the baseplate, the converter will shut down and disable the output. When the baseplate temperature has decreased by approximately 20 ºC the converter will automatically restart. Thermal Considerations The power modules operate in a variety of thermal environments however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Peak temperature TREF occurs at the position indicated in Figure Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.

For application 2, the module is cooled by heat removal into a forced airflow that passes through the interior of the module and over the top baseplate and/or attached heatsink.

Layout Considerations The JNW350R power module series are aluminum base board packaged style, as such component clearance between the bottom of the power module and the mounting Host board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to GE Board Mounted Power Modules Soldering and Cleaning Application Note. Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC Sn/Ag/Cu Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHScompliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.
