1N4712UR-1

Overview

The 1N4712UR-1 is a surface mount Zener diode manufactured by Microchip Technology. It utilizes the DO-213AA package and provides voltage regulation capabilities within the 1N4678 through 1N4717 series. The device features a nominal Zener voltage of 47 V with a standard tolerance of ±5%. It operates at a maximum power dissipation of 500 mW and includes an internal metallurgical bond for high reliability.

Feature Summary

• Surface mount equivalent of JEDEC registered 1N4678 through 1N4717 series
• Internal metallurgical bond between metal slugs and silicon die
• Low Zener test current requirement of 50 uA

Applications

• Voltage regulation in electronic circuits
• General purpose surface mount applications requiring reliable voltage reference

Procurement Notes

Verify the specific datasheet for the 1N4712UR-1 to confirm exact electrical parameters such as impedance and leakage current, as these values vary across the series. Ensure compatibility with the DO-213AA footprint during PCB design. Confirm RoHS status and manufacturing origin if required for your supply chain compliance standards.

Selection Notes

Select this component when a 47 V Zener voltage is required in a compact surface mount form factor. The 500 mW power rating suits low-power regulation tasks. Consider the ±5% tolerance for general applications; tighter tolerances may require specific screening options available within the broader series.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 W glass surface mount Zener diodes. These components are designed as direct surface mount replacements for traditional through-hole JEDEC registered devices, offering similar performance in a smaller footprint suitable for automated assembly processes.

Replacement Considerations

Direct functional equivalents include other manufacturers' DO-213AA packaged Zener diodes rated at 47 V and 500 mW. Verify pinout compatibility and thermal characteristics before substitution.
