Overview
The MD7000 is a small signal NPN bipolar transistor manufactured by Central Semiconductor Corp. It features a TO-78 metal cylindrical package with six terminals. The device has a maximum collector current of 500 mA, a collector-base breakdown voltage of 50 V, and a collector-emitter breakdown voltage of 30 V. Minimum DC current gain (hFE) is specified at 40 when the collector current is 300 mA. Saturation characteristics include a maximum base-emitter saturation voltage of 0.4 V at 30 mA collector current and a maximum collector-emitter saturation voltage of 1 V at 300 mA collector current. The transition frequency (fT) is typically 150 MHz and can reach up to 200 MHz.
Feature Summary
- NPN silicon construction for amplification and switching applications
- Metal TO-78 hermetic packaging for high reliability
- Defined hFE matching capabilities for complementary pairs
Applications
- General purpose amplifier circuits
- Switching applications requiring moderate current handling
- Complementary pair configurations using MD7001
Procurement Notes
Verify End of Life status before ordering. Last order date is six months from notice; final shipments occur within twelve months. No direct replacement part number is listed in official documentation. Contact [email protected] for alternate source assistance or custom screening inquiries.
Selection Notes
Select this component for designs requiring a TO-78 metal package NPN transistor with 500 mA collector current capability. Ensure circuit requirements align with the 30 V collector-emitter voltage limit. Consider the MD7001 as the PNP complementary counterpart if matched pairs are needed for push-pull stages.
Part Context
Central Semiconductor manufactures discrete semiconductors including transistors, diodes, and MOSFETs. The company supports legacy devices and offers custom solutions. The MD7000 belongs to a family of dual transistors in the TO-78 case, which includes variants like MD982 and MD2219A. These devices are designed for industrial, scientific, and consumer applications.
Replacement Considerations
No replacement part numbers are provided in the official discontinuation notice. The MD7000 is classified as End of Life with no direct substitute listed. Customers must contact the manufacturer's engineering team for potential alternate sourcing options.
