1500V device based on TO-220FP wide creepage package

STMicroelectronics (hereinafter ST) announced a portfolio of power transistor products in the TO-220 FullPAK (TO-220FP) Wide Creepage package. This new family of arc-resistant packages includes the world's first 1,500V Super-Junction MOSFET.

The TO-220FP wide creepage package is suitable for power transistors in open-frame power supplies used in equipment such as TV receivers or PCs. This is because surface contamination by particles such as dust can cause high-voltage arc discharge between transistor terminals.

The lead spacing of the new package has been widened to 4.25 mm, eliminating the need for special potting techniques, lead forming, sleeving, and sealing operations that are applied to prevent arcing when using existing packages with a lead spacing of 2.54 mm. Consequently, power supply manufacturers can meet appropriate safety standards and minimize field defects without applying these additional processes, thereby simplifying the manufacturing process and improving productivity.

The TO-220FP wide creepage provides excellent arc resistance while maintaining the superior electrical characteristics of the general-purpose TO-220FP. In addition, since the external dimensions are similar, design implementation is smooth, and compatibility with existing assembly processes can be maintained.

This TO-220FP wide capri package was jointly developed with SoluM, a major Korean power module manufacturer and a customer of ST. SoluM is using this superior package to produce power solutions that are more powerful and cost-effective than competing products.

ST is currently increasing mass production of TO-220FP wide creepage power transistors to support major global TV manufacturers. The product portfolio includes five types of 600V low RDS(ON) MDmesh™ M2 MOSFETs with current ratings ranging from 8A to 34A, all of which have completed quality testing. The MDmesh K5 devices, the 1,500V STFH12N150K5 and 1,200V STFH12N120K5, are scheduled to complete quality certification by the end of the third quarter of 2016.
