Overview
The MD8002 is a dual NPN silicon low noise transistor housed in a TO-78 metal can package. It features a maximum collector current of 30 mA, with collector-base and collector-emitter breakdown voltages rated at 50 V each. The device provides a minimum DC current gain (hFE) of 100 at 10 mA and 10 V. Its transition frequency (fT) is specified at a minimum of 260 MHz. The package contains two separate elements within a cylindrical metal housing.
Feature Summary
- Dual NPN configuration for compact circuit integration
- Low noise design optimized for sensitive signal amplification

- General purpose amplification and switching applications
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. Verification of final stock availability through authorized distributors is required before design commitment.
Selection Notes
Engineers should evaluate alternative low noise NPN transistors due to the discontinued status of this specific part number. Ensure that any substitute component meets the original requirements for 50 V breakdown voltage, 30 mA current handling, and 260 MHz transition frequency to maintain circuit performance integrity.
Part Context
The MD8002 belongs to the Central Semiconductor MD series of discrete bipolar transistors. This series includes various complementary and matched pairs designed for general-purpose and specialized analog applications. The MD8002 specifically targets low noise requirements within the broader portfolio of small signal devices.
Replacement Considerations
Central Semiconductor lists no direct replacement part number for the MD8002. Designers must source equivalent specifications from other manufacturers or utilize generic low noise NPN transistors that match the electrical parameters and physical footprint constraints.
