The technical specifications of 2N2222 in TO-18 metal packaging and 2N2222A transistor in TO-92 packaging are given below: Spec The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V and 75V, 40V, 6V respectively.Īlso, the 2N2222 comes in metal packaging whereas the 2N2222A is available in TO-92 plastic enclosure only.ĢN2222A is a better option considering its higher ratings, low cost, and TO-92 packaging. The emitter is denoted by ‘ E’.ĢN2222 VS 2N2222A: What’s the difference?īoth are similar types of transistors but the 2N2222A has higher Maximum absolute ratings than 2N2222. This pin act as an outlet and the current comes out of the transistor from here. This pin controls the transistor biasing. This pin act as an inlet as the current enters the transistor from here.
