1N4135UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4135UR-1/TR is a surface mount Zener voltage regulator in the DO-213AA package. It provides a nominal breakdown voltage of 100V with standard 5% tolerance. The device features an internal metallurgical bond, indicated by the -1 suffix, and supports a power dissipation of 0.5W. 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 design equivalent to JEDEC registered axial types
• Military qualification available under JAN, JANTX, and JANTXV standards

Single Zener Diodes Applications

• Voltage regulation in military electronic systems
• Precision reference circuits requiring stable breakdown voltage
• Protection against overvoltage transients in harsh environments

Single Zener Diodes Procurement Notes

Verify that the ordering part number includes the specific suffixes required for your application. Confirm whether the -1 suffix for internal metallurgical bonding is necessary. Ensure the TR suffix indicates tape and reel packaging if automated assembly is used. Check for RoHS compliance requirements and confirm the specific military grade (JAN, JANTX, or JANTXV) matches the system specifications.

Single Zener Diodes Selection Notes

Select this component when a robust surface mount Zener diode is needed for high-reliability applications. The internal metallurgical bond offers superior mechanical stability compared to non-bonded variants. Consider the 0.5W power rating and 100V breakdown voltage to ensure compatibility with the circuit's voltage and current limits. Verify thermal management capabilities for the operating environment.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 0.5-watt glass surface mount Zener regulators. These components serve as surface mount equivalents to the traditional JEDEC registered 1N4099 through 1N4135 axial-leaded series. The series covers a voltage range from 1.8 to 100 volts, providing options for various regulation needs in compact form factors.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA packaged Zener diodes with matching 100V breakdown and 0.5W power ratings. Ensure any substitute also meets the required military or industrial temperature ranges. Verify that the replacement maintains similar reverse leakage current and impedance characteristics.
