summary:
The 2N2218, 2N2219, 2N2221 and 2N2222 are silicon planar epitaxial NPN transistors in Jedec TO-39 (for 2N2218 and 2N2219) and in Jedec TO-18 (for 2N2221 and 2N2222) metal cases. They are designed for high-speed switching applications at collector currents up to 500 mA, and feature useful current gain over a wide range of collector current,low leakage currents and low saturation voltages.
Features
Excellent hFE Linearity
hFE(IC=0.1mA)/hFE(IC=2mA)=0.95(Typ.).
Low Noise :NF=1dB(Typ.) at f=1kHz.
