1N4135DUR-1

Single Zener Diodes Overview

The Microchip Technology 1N4135DUR-1 is a 100V Zener diode with 1% voltage tolerance, housed in a surface-mount glass DO-213AA package. It features an internal metallurgical bond and operates within a temperature range of -65°C to +175°C. The device has a rated power dissipation of 0.5W at 25°C, derating linearly to zero at 175°C. Electrical characteristics include a maximum reverse current of 1µA and a dynamic impedance of 0.01 Ohms at the test current of 250µA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF-style surface mount construction
• Internal metallurgical bond for high reliability
• Qualified per MIL-PRF-19500/435 standards

Single Zener Diodes Applications

• Voltage regulation over broad current and temperature ranges
• High reliability applications requiring radiation hardness
• ESD protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates 1% tolerance and 'UR' denotes the surface mount package. Confirm RoHS compliance status as it varies by grade. Check for JAN, JANTX, JANTXV, or JANS qualification levels if military specifications are required. Ensure ordering documentation matches the exact part number format.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode with tight voltage tolerance is needed. Consider the 0.5W power rating and thermal resistance values for heat dissipation requirements. Verify that the operating temperature range meets the application's environmental conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 500mW Zener voltage regulators. It serves as the surface mount equivalent to the axial-leaded JEDEC registered 1N4099 through 1N4135 series. The series offers voltages from 1.8V to 100V with various tolerance options.

Single Zener Diodes Replacement Considerations

Commercial equivalents include CDLL4135-1. Axial-leaded replacements are available as 1N4135-1. Surface mount alternatives exist in DO-216 packages such as 1PMT4135.
