1N4736 G

Overview

The Microsemi Corporation 1N4736 G is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6V with a standard tolerance of 5%. The device is rated for a power dissipation of 0.5W and operates within a temperature range from -65°C to +175°C. It utilizes a glass axial-lead DO-35 package, which provides hermetic sealing suitable for high-reliability environments. The component is classified as non-RoHS compliant.

Feature Summary

• Hermetically sealed glass body construction for enhanced environmental protection
• High-temperature operation capability up to 175°C
• Standard 5% voltage tolerance for general-purpose regulation

Applications

• Voltage reference circuits in harsh environments
• Overvoltage protection for sensitive electronic components
• General-purpose voltage regulation in aerospace systems

Procurement Notes

Verify the specific suffix requirements for your application, as the 'G' designation indicates a glass-body variant. Confirm RoHS compliance status if required by your manufacturing standards, as this specific part is listed as non-compliant. Ensure that the DO-35 package dimensions align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a hermetically sealed, high-temperature capable Zener diode is required. The 0.5W power rating makes it suitable for low-power regulation tasks. Consider the glass package for superior thermal stability compared to plastic alternatives in extreme conditions.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microsemi. These devices are widely recognized for their reliability in military and aerospace applications. The series offers various voltage options within a consistent form factor, allowing for standardized design approaches across different voltage regulation needs.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4736A variants in DO-35 packages. Verify electrical characteristics such as Zener impedance and test current to ensure compatibility. Check for hermetic sealing requirements if replacing with non-hermetic plastic versions.
