lead frame technical field discloses a TO263
lead frame, including the
product group of N along the length direction of
lead frame sequential connection,
product group includes a horizontal main
ligament, two longitudinal main ligaments and two product units, two longitudinal main ligaments are connected with horizontal main
ligament both ends, and two product units are set between two longitudinal main ligaments along the length direction of lead frame, product unit includes base island, gate pole bonding platform and source
electrode bonding platform, when using, the utility model only sets up gate pole bonding platform and source
electrode bonding platform in base island one side, and the area of gate pole bonding platform and source
electrode bonding platform has been increased, can reduce the risk of gate pole false
welding, and simultaneously, source electrode bonding platform can bond more quantity's bonding wire, and current
carrying capacity promotes, in addition, the bottom surface of base island is the drain electrode of product unit, and the creepage distance between source electrode bonding platform and drain electrode is promoted, can satisfy the special application demand of customer.
