SIMPLE SWITCHER® Extended Temperature (EXT) Power Modules
SIMPLE SWITCHER EXT power modules provide excellent performance in the most extreme conditions, with extended ambient temperatures guaranteed down to -55˚ C and shock and vibration testing that meets military and industrial standards.
Military
Packaged in a completely enclosed plastic molding, the EXT power modules feature leads and a single exposed metal bottom ideal for harsh environments.
Industrial
Low EMI, excellent thermal performance, and high reliability enable today's state-of-the art production facilities to operate at peak performance.
- High Reliability
- Leads offer board-to-device stress relief from varying ambient temperatures
- Single exposed bottom offers secure bonding to printed circuit boards (PCBs)
- Excellent thermal performance eliminates the need for external heat sinks and fans
- Semiconductor integrated circuit level reliability and performance for rugged environments
- Fully RoHS compliant
Faster Development Time
- Large exposed bottom removes shearing effect during shock and vibration conditions
- Highly integrated solution simplifies board layout and design qualification, lowers manufacturing and overall risk
