Overview
The MD2905A is a PNP amplification and switching transistor manufactured by Central Semiconductor Corp. It utilizes the TO-78 metal can package for through-hole mounting. The device supports a maximum collector current of 600 mA, with a collector-base breakdown voltage of 60 V and a collector-emitter breakdown voltage of 60 V. DC current gain (hFE) ranges from 100 to 300 at a collector current of 10 mA and VCE of 150 V. Saturation characteristics include a maximum VCE(sat) of 0.4 V at IC = 300 mA and IB = 10 mA. Transition frequency (fT) is specified between 150 MHz and 200 MHz.
Feature Summary
- PNP bipolar junction transistor configured for amplification and switching applications
- High-voltage capability with 60 V collector-base and collector-emitter ratings
- Metal TO-78 hermetic package designed for high-reliability environments
Applications
- General-purpose amplification circuits

Procurement Notes
This component has been officially transitioned to End of Life status by Central Semiconductor Corp. No replacement part numbers are currently available in their portfolio. Procurement must rely on existing inventory or secondary market sources. Verify manufacturing date codes carefully, as production has ceased. Contact [email protected] for technical data regarding potential alternate sourcing strategies.
Selection Notes
Select this component only if legacy compatibility with the TO-78 metal case is required. Note that the standard MD2905A lacks matched pair specifications; variants such as the MD2369B offer defined matching parameters. Ensure designs account for the discontinuation status when planning long-term production lifecycles.
Part Context
The MD2905A belongs to a family of dual transistors produced in the TO-78 case style. This specific entry serves as the PNP counterpart within complementary pairs, often associated with NPN types like the MD7000. The device is documented in Central Semiconductor's product lineup alongside other military-grade discrete semiconductors.
Replacement Considerations
No direct replacement part numbers are listed by the manufacturer. The official notice indicates 'N/A' for all discontinued items in this category. Engineers must identify equivalent devices from other manufacturers that match the TO-78 footprint and electrical specifications.
FAQ
What is the maximum collector-emitter breakdown voltage?
The maximum collector-emitter breakdown voltage (VCEO) is 60 V.
Is the MD2905A available as a matched pair?
The standard MD2905A does not have specified matching parameters. Matched versions exist for other models in the series, such as the MD2369B.
What is the transition frequency range?
The transition frequency (fT) ranges from 150 MHz to 200 MHz.
