Description
General part information
2N4449UA-Transistor Series
This specification covers the performance requirements for NPN, silicon, high speed switching 2N2369A, 2N3227 and 2N4449 transistors (including dual devices). Four levels of product assurance (JAN, JANTX, JANTXV and JANS) are provided for each device type as specified in MIL-PRF-19500/317 and two levels of product assurance (JANHC and JANKC) are provided for each unencapsulated device type. Provisions for radiation hardness assurance (RHA) to two radiation levels ("R" and "F") are provided for JANTXV product assurance level. Provisions for RHA to eight radiation levels are provided for JANS and JANKC. RHA level designators "M", "D", "P", "L", "R", "F’, "G", and "H" are appended to the device prefix to identify devices, which have passed RHA requirements.
