2N2484 is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS NPN 60V 0.05A TO-18. Review the specifications below when checking this part for your BOM.
The 2N2484 is a discontinued NPN silicon small-signal transistor manufactured by onsemi. It features a collector-emitter voltage of 60 V and a continuous collector current rating of 50 mA. The device operates within an ambient temperature range of -65°C to +200°C with a total power dissipation of 360 mW at 25°C. It utilizes a TO-18 metal can package and is qualified under MIL-PRF-19500/376 standards.
This component is officially discontinued and no longer manufactured. Verification should focus on legacy stock availability from authorized distributors or surplus suppliers. Ensure that any acquired units meet the specific quality levels defined in the original MIL-PRF-19500/376 specification, as manufacturing processes may vary among secondary sources.
Select this part only for maintenance of existing designs requiring MIL-qualified components. Consider modern equivalents if new production is required, as supply is limited. Verify package compatibility with existing TO-18 footprints and confirm thermal management capabilities align with the 360 mW dissipation limit at elevated temperatures.
The 2N2484 belongs to the family of NPN silicon low-power transistors historically produced for defense and aerospace sectors. Manufactured by onsemi (formerly Microsemi), it adheres to strict military reliability standards. The TO-18 package provides robust environmental sealing, making it suitable for harsh operating conditions where standard plastic packages would fail.
Public confirmed substitute part numbers: 2N2484UA, 2N2484UB, 2N2484UBC.
