PowerPAK 1212-8, the proven automotive package
The automotive industry embraces a new package type only after a track record has been established and extensive testing has been carried out both by manufacturers and systems engineers. This article explains the characteristics that have led designers to select the PowerPAK 1212-8 for a wide range of automotive applications such as engine control units (ECU) and fuel injection systems.
This application note presents useful information on the PowerPAK 1212-8 to facilitate SQE and design engineers. Vishay introduced the PowerPAK power MOSFET package family in the late 1990s to provide a thermally efficient solution for the computer and telecom markets. PowerPAK's combination of a small form factor and high power handling capabilities quickly brought industry-wide acceptance in various applications such as dc-to-dc power supplies, point of load, and control actuators.
In most such applications, the PowerPAK SO-8 and often the PowerPAK 1212-8 can replace the much larger and bulkier DPAK. The automotive industry embraces a new package type only after a track record has been established and extensive testing has been carried out both by manufacturers and systems engineers. The PowerPAK 1212-8 has undoubtedly won the industry's acceptance and has been successfully tested for AEC-Q101 compliance. The package has also successfully been tested on a 16-layer PC board assembly for solder joint reliability, passing the temperature cycles, including the re-work, as per IPC 9701 test guidelines.
Automotive designers have ventured to use the PowerPAK 1212-8 in such crucial applications as engine control units (ECU) and fuel injection systems. These applications demand power cycling and some UIS capabilities. PowerPAK’s reliability has likewise encouraged designers to use the PowerPAK 1212-8 to replace die-level implementations, thereby eliminating the associated assembly costs while utilizing well established reflow processes. As of April 2010, more than 5.5 million PowerPAK power MOSFETs had been shipped to Vishay automotive customers worldwide.
