2n2219 vs 2n2222

2N5172 NPN 2N6076 PNP COMPLEMENTARY SILICON TRANSISTORS R1 (7-February 2014) www.centralsemi.com NPN TYPICAL ELECTRICAL CHARACTERISTICS > transistors are available in both 2n and PN varieties, such as 2N2222 vs > PN2222 and 2N5179 vs PN5179. The PN's seem to be cheaper. > What's the difference between the two? > Thanks and 73, > Tom AB9B The 2N2222, often referred to as the 'quad two' transistor, is a small, common NPN BJT transistor used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.
