Re: Metal Can type IC opamp & Transistors VS plastic type IC opamp & transistors
For ICs, such as op amps, the metal can package (such as TO-99) is becoming vdery uncommon. Metal cans are associated with special, high reliability parts. I suppose for transistors, they offer a particular type of heat sink to be used. A major disadvantage of any metal can part is not being surface mounted. I will bet there are many designers who have not used a metal can in many years. Cans are definitely "old school". OK, bring it on now that I said it...
