MD918

Overview

The MD918 is an NPN silicon dual transistor manufactured by Central Semiconductor Corp. It is housed in a TO-78 metal can package designed for through-hole mounting. The device integrates two independent NPN transistors within a single component, offering a compact solution for circuit designs requiring multiple switching or amplification stages. This specific part number represents the base configuration of the MD918 series.

Feature Summary

Dual NPN transistor configuration within a single unit
Silicon planar construction for reliable performance
Metal can packaging providing robust physical protection

Applications

General-purpose switching circuits
Amplifier stages requiring dual transistor pairs
Logic interface applications

Part Context

The MD918 belongs to the broader family of dual NPN silicon transistors produced by Central Semiconductor. Variants such as the MD918A and MD918B exist, typically differing in gain classification or testing parameters while maintaining the same electrical structure and pinout compatibility.

Replacement Considerations

Central Semiconductor has officially classified the MD918 as End of Life (EOL). The manufacturer's discontinuation notice lists 'N/A' in the replacement column, indicating that no direct substitute from Central Semiconductor is currently available for this component.
