The ESTW006A0B provides 12V nominal output voltage rated for 6A output current. The module incorporates GE’s vast heritage for dc dc reliability and quality, while also using the latest in technology and component and process standardization to achieve highly competitive cost. The open frame module construction, available in both surface mount and through-hole packaging, enables designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 90% at V =48V . Standard features include remote On/Off, remote sense, output voltage adjustment, IN dc overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard, eighth-brick heat sink attachment to achieve higher output current in high temperature applications. * Trademark of General Electric Company # UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. § This product is intended for integration into end-user equipment .

To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 10 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum DC input current, the same type of fuse with a lower rating can be used.

Reflow Soldering Information The surface mountable modules in the ESTW006A0Bxx-S family use our newest SMT technology called “Column Pin” (CP) connectors. Figure 22 shows the new CP connector before and after reflow soldering onto the end-board assembly. The CP is constructed from a solid copper pin with July 15, 2015 ©2015 General Electric Company.

Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. For established by accurately measuring the modules CP reliable soldering, the solder reflow profile should be connector temperatures. Lead Free Soldering o Figure 24.

This standard provides a recommended forced-air-convection reflow 50 profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu 0 Reflow Time (Seconds) (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Figure 25. Figure 25. Recommended linear reflow profile using Sn/Ag/Cu solder. 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 (AN04-001). REFLOW TIME (S) Figure 23.
