2N2222A : MIL-PRF-19500/255: 50 V, 800 mA NPN Small Signal Transistor, MIlitary Qualified
The ON Semiconductor 2N2222A small signal NPN silicon epitaxial switching transistor is on the US DLA Land and Maritime Qualified Products List (QPL) and available in versions meeting JAN, JANTX and JANTXV quality levels. All versions of the 2N2222A are supplied in a hermetically sealed TO-18 package. Target applications for the MIL-PRF-19500/255-qualified devices include switching and linear amplification in missile guidance, munitions, radio communications, commercial and military avionics and other military and aerospace systems where high reliability in harsh conditions and longevity of product supply are key design considerations.
P2N2222A : NPN Bipolar Transistor
The 2N2222 is a very common NPN silicon switching transistor. It is commonly found in the TO-18 metal can package, but replacements can also be found in the less expensive TO-92 package as well as surface-mount packages SOT-23 and SOT-223.
Currently the 2N2222 is sourced by manufacturers such as Central Semiconductor, Comset Semiconductor, Fairchild Semiconductor, Micro Commercial Components (MCC), Microsemi Corporation, NTE Electronics, STMicrolectronics and OPTEK Technology.
There are a few related transistors such as the 2N2907 (PNP complement), 2N3904 (1/3 the current with similar characteristics) and the 2N2219 (higher power dissipation rating).
