Rated for 50 V collector-emitter breakdown and 800 mA continuous collector current, it handles general-purpose switching and amplification in a hermetically sealed metal can. ## Thermal envelope and gain at operating point The metal-can package conducts heat to the board or heatsink clip more effectively than a plastic TO-92 — useful when the transistor sits near a hot regulator or in a cramped enclosure. DC current gain (hFE) is specified at 100 minimum at Ic=150 mA and Vce=10 V — this is the typical switching point for driving relays or small solenoids. Vce saturation is 1 V max at 50 mA base drive and 500 mA collector current, keeping conduction losses manageable at moderate duty cycles. ## Active production, bulk pack, multi-source reality It ships in bulk (tube or bag), not tape-and-reel, which suits bench stock, repair depots, and low-to-medium volume builds where reel packaging adds waste. The base part number 2N2222 is a JEDEC-registered device produced by multiple manufacturers. The Microchip TO-18 variant is interchangeable with the same package from other qualified sources, though the AE4 suffix is Microchip-specific.","metaTitle":"Microchip 2N2222AE4 NPN Transistor, 50 V, 800 mA, TO-18","metaDescription":"2N2222AE4 NPN transistor from Microchip Technology. 50 V Vce, 800 mA Ic, 500 mW Pd, TO-18 metal can.
