PSOP3 is a leadframe based, plastic encapsulated package that is well suited for applications requiring optimum performance in IC packaging. This industry standard package utilizes a thick copper heat slug to accommodate the needs of higher power devices. A green BOM is standard, allowing devices to meet applicable Pb-free and RoHS standards.
