1N4135UR-1

Single Zener Diodes Overview

The 1N4135UR-1 is a surface mount Zener voltage regulator manufactured by Microchip Technology. It features a DO-213AA glass package and provides a nominal Zener voltage of 100 V with a standard tolerance of ±5%. The device has a maximum power dissipation of 500 mW and an internal metallurgical bond construction, indicated by the -1 suffix. It operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Surface mount DO-213AA glass package design
• Qualified per MIL-PRF-19500/435 standards

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Military and aerospace electronic systems
• Precision reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific revision level and manufacturing origin when sourcing this component. Confirm that the part number includes the -1 suffix to ensure the presence of the internal metallurgical bond feature. Check for RoHS compliance status if required by your assembly specifications, as commercial and military versions may differ in environmental compliance documentation.

Single Zener Diodes Selection Notes

Select this component when a robust surface mount Zener diode is required for high-voltage regulation applications. The 100 V rating and 500 mW power handling capability suit moderate current requirements. The metallurgical bond construction makes it suitable for environments requiring higher mechanical stability compared to non-bonded equivalents.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5 watt glass surface mount Zener voltage regulators. These devices are designed as surface mount equivalents to JEDEC registered axial-leaded parts. The series offers voltages from 1.8 to 100 volts, with the -1 suffix denoting the internal metallurgical bond option available in JAN, JANTX, and JANTXV military qualifications.

Single Zener Diodes Replacement Considerations

Non-bonded equivalents such as 1N4135UR are available without the -1 suffix. Axial-leaded counterparts include the 1N4135 in the DO-35 package. Ensure any substitute maintains the required voltage tolerance and power dissipation ratings for the specific application.
