Procurement Notes
This component has been officially classified as End of Life by the manufacturer. No direct replacement part numbers are currently available within the Central Semiconductor portfolio. Customers must submit technical inquiries via the manufacturer's official portal to explore potential alternate sourcing options or verify final shipment availability windows.
Selection Notes
Engineers should evaluate the TO-39 package constraints and the specific thermal resistance requirements for their design. Given the discontinuation status, alternative sourcing strategies must be prioritized. Verify that the required current and voltage ratings align with the 3.5 A and 65 V limits before proceeding with any legacy inventory acquisition.
Part Context
The 2N5784 belongs to a complementary pair alongside the PNP 2N5781, both manufactured by Central Semiconductor Corp. These devices were engineered for high-current applications requiring robust silicon construction. The TO-39 hermetic metal case provides superior thermal conductivity compared to plastic packages, facilitating efficient heat dissipation in demanding environments.
Replacement Considerations
No equivalent replacement part numbers are listed in the manufacturer's End of Life notice. Users are advised to contact Central Semiconductor directly through their online inquiry system to request assistance in locating suitable third-party alternatives.
