Overview
The Central Semiconductor Corp 2N2914 is a dual NPN low-noise transistor housed in a TO-78 metal can package. It features a collector current of 30 mA, a collector-base voltage of 45 V, and a collector-emitter voltage of 45 V. The device provides a minimum DC current gain (hFE) of 150 at 150 µA and 600 at 1 mA. Saturation characteristics include a maximum VCE(sat) of 0.35 V at 1 mA and a transition frequency (fT) of 1.0 MHz. Power dissipation is rated at 600 mW total at 25°C ambient temperature.
Feature Summary
- Dual NPN configuration within a single hermetically sealed metal can
- Optimized for low-noise amplifier applications
- Matched electrical parameters between the two internal transistors
Applications
- Low-noise preamplifier stages
- Precision analog signal processing circuits
- Balanced differential amplifier inputs
Procurement Notes
This component has been officially classified as End of Life by Central Semiconductor Corp. No replacement part numbers are currently available from the manufacturer. Procurement should focus on verifying existing inventory availability or identifying equivalent specifications from other suppliers, as direct replacements are not listed in official documentation.
Selection Notes
Select this component for designs requiring matched dual NPN transistors with low noise characteristics in a TO-78 package. Verify that the 45 V voltage ratings and 30 mA current limits meet circuit requirements. Note that due to its End of Life status, long-term supply continuity cannot be guaranteed, necessitating careful evaluation of alternative sourcing strategies.
Part Context
The 2N2914 belongs to a series of dual NPN low-noise transistors manufactured by Central Semiconductor Corp in the TO-78 case style. This specific device is grouped with similar parts like the 2N2913 and 2N2915, sharing identical voltage and current ratings but differing in hFE matching criteria. All devices in this TO-78 lineup have been discontinued.
Replacement Considerations
No replacement part numbers are provided in the official datasheet or discontinuation notice. Users must seek equivalents from other manufacturers based on matching electrical parameters and package dimensions.
