2N2218-2N22192N2221-2N2222HIGH-SPEED SWITCHESDESCRIPTIONThe 2N2218, 2N2219, 2N2221 and 2N2222 are sili-con planar epitaxial NPN transistors in JedecTO-39 (for 2N2218 and 2N2219) and in JedecTO-18 (for 2N2221 and 2N2222) metal cases. Theyare designed for high-speed switching applicationsat 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.2N2218/2N2219 approved to CECC 50002-TO-39TO-18100, 2N2221/2N2222 approved to CECC50002-101 available on request.INTERNAL SCHEMATIC DIAGRAMABSOLUTE MAXIMUM RATINGSSymbol Parameter Value UnitVCBO Collector-base Voltage (IE =0) 60 VVCEO Collector-emitter Voltage (IB = 0) 30 VVEBO Emitter-base Voltage (IC =0) 5 VIC Collector Current 0.8 APto t Total Power Dissipation at T 25 Cambfor 2N2218
