1N4736UR

Overview

The Microchip Technology 1N4736UR is a surface-mount Zener diode designed for voltage regulation applications. It operates within the DO-213AA-2 package and dissipates up to 1 W of power. The device maintains a nominal Zener voltage of 6.8 V with a standard tolerance of 5%. It functions reliably across an extended temperature range from -65 °C to +175 °C, ensuring stability in demanding environments.

Feature Summary

• Surface-mount construction compatible with automated assembly processes
• Hermetically sealed glass encapsulation for environmental protection
• Extended thermal operating range suitable for high-reliability systems

Applications

• Voltage reference circuits requiring stable potential
• High-density board layouts with low parasitic requirements
• Military and aerospace electronics governed by source control drawings

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with JEDEC outline standards before integration. Confirm RoHS compliance status through manufacturer documentation to meet regulatory requirements for your specific deployment region.

Selection Notes

Select this component when space constraints necessitate a MELF-style footprint while maintaining the performance characteristics of traditional axial Zener diodes. Evaluate the 1 W power dissipation capability against circuit load requirements. Consider the hermetic seal benefits for harsh environment deployments where moisture resistance is critical.

Part Context

This part belongs to the 1N47xx series of surface-mount Zener diodes manufactured by Microchip Technology. It serves as the SMD equivalent to the legacy 1N4736A axial component, adapting the proven design to the DO-213AB/DO-213AA outline. The series supports various voltage ratings within the 1 W power class.

Replacement Considerations

The 1N4736A is the direct axial leaded equivalent. Verify pinout orientation and physical dimensions during substitution to ensure mechanical fit.
