1N5236BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5236BUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 7.5 V at a test current of 20 mA. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W. The device features a maximum dynamic impedance of 6.0 Ohms, a reverse leakage current of 3.0 µA, and a positive temperature coefficient of +0.058 %/°C. Packaged in the DO-213AA MELF style, it utilizes metallurgically bonded glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed surface mount package with internal metallurgical bond
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard design
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High reliability electronic assemblies requiring hermetic sealing
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (B for 5%) against the required circuit specifications. Confirm that the DO-213AA footprint matches the PCB layout. Ensure the supplier provides documentation confirming the metallurgically bonded construction and RoHS compliance status if applicable to the commercial grade version.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The 7.5 V rating suits circuits needing precise reference voltages. Consider the low capacitance for signal integrity and the radiation hardness for aerospace or defense environments where standard plastic packages may fail.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount equivalent to the JEDEC registered axial-leaded 1N5221 to 1N5281 series. The series covers Zener voltages from 2.4 V to 200 V in a 0.5 W power rating configuration.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA (SOD80/MLL34) packaged Zener diodes rated at 7.5 V with similar power dissipation. Verify thermal resistance and leakage current limits match the original design requirements.
