Single Zener Diodes Overview

The 1N4130UR-1 is a Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a DO-213AA-2 package and operates within a temperature range of -65°C to +175°C. The device provides a nominal Zener voltage of 68V with a tolerance of 5%. It has a maximum power dissipation of 500 mW and a Zener impedance of 700 Ohms. The component utilizes silicon technology and is available in bulk packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 68V with 5% tolerance
• Operates reliably across an extended temperature range from -65°C to +175°C
• Utilizes a compact DO-213AA-2 surface-mount glass package

Single Zener Diodes Applications

• Voltage reference circuits requiring high-temperature stability
• Overvoltage protection in harsh environments
• Precision voltage regulation in aerospace systems

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' indicates metallurgical bonding if required for your application, as this affects thermal performance and reliability compared to standard versions. Confirm RoHS status (listed as N) against project environmental compliance requirements. Check current availability and lead times directly with authorized distributors, as production cycles may vary. Ensure the DO-213AA-2 footprint matches your PCB design constraints.

Single Zener Diodes Selection Notes

Select this component when a 68V Zener voltage is needed in a surface-mount format capable of withstanding extreme temperatures up to 175°C. The 500mW power rating suits low-current regulation tasks. Consider the 700 Ohm impedance for noise-sensitive applications where higher impedance might be beneficial. Compare against standard 1N4130 variants if hermetic sealing or specific military qualification is not mandatory.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zener diodes. These devices offer a wide selection of voltages from 1.8 to 100 volts in standard 5% tolerances. The 'UR-1' designation typically denotes a specific construction variant, often involving metallurgical bonding for enhanced reliability in demanding environments.

Single Zener Diodes Replacement Considerations

Standard 1N4130 equivalents may lack the specific metallurgical bond or extended temperature range if the '-1' suffix implies military-grade construction. Verify pinout compatibility with the DO-213AA-2 package. Alternative surface-mount Zeners must match the 68V nominal voltage, 500mW power rating, and operating temperature limits.
