1N4109UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4109UR-1 is a surface-mount Zener voltage regulator featuring a DO-213AA-2 (SOD-80) package. It provides a nominal Zener voltage of 15 V with a 5% tolerance and a maximum reverse leakage current of 50 nA. The device operates within a temperature range of -65°C to +175°C, dissipating up to 500 mW of power. Key electrical parameters include a Zener impedance of 100 ohms and a test current of 250 µA.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Surface mount design equivalent to JEDEC registered through-hole series
• High operating temperature capability suitable for demanding environments

Single Zener Diodes Applications

• Voltage regulation in surface mount circuits
• Overvoltage protection applications
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific manufacturer documentation to confirm exact electrical tolerances and thermal characteristics. Ensure the procurement specifications align with the required surface mount package type and operating temperature range. Cross-reference the part number suffix to confirm the internal metallurgical bond feature is included as specified.

Single Zener Diodes Selection Notes

Select this component when a robust surface mount Zener diode with high-temperature stability is required. The internal metallurgical bond offers superior mechanical integrity compared to non-bonded types. Consider the 500 mW power dissipation and 15 V rating to ensure compatibility with the target circuit's voltage and power requirements.

Single Zener Diodes Part Context

This component belongs to the 1N4099UR-1 through 1N4135UR-1 series of metallurgically bonded glass surface mount Zener diodes. Manufactured by Microchip Technology, these devices serve as surface mount equivalents to traditional JEDEC registered through-hole Zener regulators, providing reliable voltage regulation in compact PCB layouts.

Single Zener Diodes Replacement Considerations

Non-bonded versions without the "-1" suffix are available but lack the internal metallurgical bond. Other parts in the series offer different voltage ratings while maintaining the same package and construction style.
