1N4716UR-1

Single Zener Diodes Overview

The 1N4716UR-1 is a surface mount Zener diode manufactured by Microchip Technology. It utilizes the DO-213AA (SMB) package and provides a nominal Zener voltage of 39 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 0.5 W at +50°C, with derating required above this temperature. It features an internal metallurgical bond between the metal slugs and the silicon die to ensure high reliability. The component operates within a junction temperature range of -65°C to +175°C and supports a test current of 50 µA.

Single Zener Diodes Feature Summary

• Surface mount construction in a DO-213AA package serving as an equivalent to the JEDEC registered 1N4716 series.
• Internal metallurgically bonded die attachment for enhanced structural integrity and reliability.
• Wide operating temperature range supporting extreme environmental conditions.

Single Zener Diodes Applications

• Voltage regulation in surface mount circuit designs
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in precision circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm it denotes commercial grade screening rather than military MIL-PRF-19500 standards. Ensure the procurement specification matches the required DO-213AA footprint and that the 0.5 W power rating aligns with the thermal management capabilities of the target PCB layout.

Single Zener Diodes Selection Notes

Select this component when a compact surface mount solution is required for 39 V regulation applications. The DO-213AA package offers a smaller footprint compared to through-hole alternatives while maintaining the 0.5 W power handling capability. Verify that the ±5% voltage tolerance meets the circuit requirements and that the low test current of 50 µA is compatible with the biasing network design.

Single Zener Diodes Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 W glass surface mount Zener diodes. The series covers a voltage selection from 1.8 V to 43 V. These devices are designed to provide a direct surface mount replacement for traditional axial leaded Zener diodes, facilitating automated assembly processes in modern electronics manufacturing.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA packaged Zener diodes with a 39 V nominal voltage and 0.5 W power rating. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with the 1N4716A series if through-hole packaging is acceptable.
