Description

General part information

1N4678-Zener-Diode Series

The 1N4678-1 thru 1N4717-1 series of 0.5 watt Zener voltage regulators provides a selection from 1.8 to 43 volts in standard 5% tolerances as well as tighter tolerances. These axial leaded glass DO-35 Zeners are available with an internal metallurgical bond similar to military requirements for similar Zeners. Microchip also offers numerous other Zener products to meet higher and lower power applications.
