2N2222 Datasheet | STMicroelectronics

DESCRIPTION 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 m A, and feature useful current gain over a wide range of collector current, low leakage currents and low saturation voltages. 2N2218/2N2219 approved to CECC 50002100, 2N2221/2N2222 approved to CECC 50002-101 available on request. 2N2218-2N2219 2N2221-2N2222 HIGH-SPEED SWITCHES TO-39 TO-18 INTERNAL SCHEMATIC DIAGRAM ABSOLUTE MAXIMUM RATINGS Symbol VCBO VCEO VEBO IC Pto t T stg Tj Parameter Collector-base Voltage (IE = 0) Collector-emitter Voltage (IB = 0) Emitter-base Voltage (IC = 0) Collector Current Total Power Dissipation at T amb ≤ 25 °C for 2N2 21 8 and 2 N22 19 for 2N2 22 1 and 2 N22 22 at T c as e ≤ 25 °C for 2N2 21 8 and 2 N22 19 for 2N2 22 1 and 2 N22 22 Storage Temperature Junction...
