ABSTRACT:
A surface mounted diode comprises a pair of slugs pointed toward each other with a die disposed therebetween, at least one of the slugs being truncated cone shape, and a pair of solder wafers being disposed between the die and each slug to form an electrical connection therebetween. Each slug has a terminal formed at the tail thereof. The largest diameter of the truncated cone shape slug is approximately the same as or greater than the diagonal of the die. The function of the truncated shape of the slug is to protect the die from damage during handling and during curing of the encapsulating resin which occurs during the manufacturing process of the surface mounted diode.
