Description

General part information

2N4859UB-JFET-NChannel Series

This specification covers the performance requirements for N-channel, depletion mode, silicon 2N4856 through 2N4861 J-FET (Junction Field Effect transistor). Four levels of product assurance are provided for each device (JAN, JANTX, JANTXV, and JANS) as specified in MIL-PRF-19500/385. 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. The device package outlines are as follows: TO-18 (no suffix) and surface mount (UB suffix) for all encapsulated device types.
