Overview
The Microsemi Corporation 1N4759 G is a silicon Zener voltage regulator diode designed for through-hole mounting in a DO-35 glass axial-leaded package. This component provides stable voltage regulation within the standard 1N746 to 1N759A series range, offering voltages from 2.4 to 12 volts with standard 5% or 10% tolerances. It features an internal metallurgical bond option and is available in RoHS-compliant versions by adding an 'e3' suffix.
Feature Summary
- JEDEC registered device within the 1N746 to 1N759A series
- Internal metallurgical bond construction similar to military devices
- Hermetically sealed glass encapsulation
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection
Procurement Notes
Verify the specific Zener voltage value required for your application, as the base part number covers a range of voltages. Confirm if the 'G' suffix denotes a specific tolerance or packaging variation compared to standard commercial equivalents. Check for RoHS compliance requirements and ensure the DO-35 package dimensions match your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when hermetic sealing and high reliability are required for low-voltage regulation applications. The DO-35 package offers a compact form factor suitable for space-constrained designs. Consider the internal metallurgical bond for enhanced stability compared to standard plastic packages. Evaluate the available voltage options within the series to find the exact rating needed.
Part Context
This part belongs to the popular 1N746 through 1N759A series of 0.5-watt Zener Voltage Regulators manufactured by Microsemi. These devices provide a wide selection of voltages in a standard DO-35 glass body. The series is known for its reliability and is often used as a direct replacement for older military-grade components in commercial applications.
Replacement Considerations
Commercial surface mount equivalents are available in the MLL746 to MLL759A series using the DO-213AA MELF style package. For higher power requirements, consider the 1W DO-41 series such as the 1N4728A through 1N4764A.
