INTERNAL SCHEMATIC DIAGRAM

2N2218/2N2219 approved to CECC 50002-

100, 2N2221/2N2222 approved to CECC

50002-101 available on request.

The 2N2218, 2N2219, 2N2221 and 2N2222 are sili-

con 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 use-

ful current gain over a wide range of collector cur-

rent, low leakage currents and low saturation volt-

ages.
