Specifically, for example, in the case of 800 V, it is said that a creepage distance of 2.1 mm is required, and if only a creepage distance of about 1.7 mm can be secured with five equally-spaced conventional pins, It was not enough. However, according to the structure of the present invention, the distance between the third pin and the second and fourth pins adjacent to each other is increased to 2.54 mm, and a distance of about 5.8 mm can be obtained between the upper and lower rows. Depending on the forming angle, the distance at the tip of the lead bin can be further increased, so that a sufficient creepage distance can be secured for safety.
- the package has a full mold structure, and the header to which the high-potential drain electrode adheres is not exposed on the back surface, making product handling safe and easy.
