1N5237/TR

Single Zener Diodes Overview

The Microchip Technology 1N5237/TR is a single Zener diode designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a 10% tolerance and operates within a temperature range of -65°C to +175°C. The component dissipates up to 500 mW and utilizes the DO-213AA (SOD-80) surface-mount package. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 8 Ohms at a test current of 20 mA, and a forward voltage of 1.1 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single Zener junction structure
• Engineered for surface-mount assembly via compact axial-equivalent packaging
• Capable of operation in extended industrial temperature environments

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Over-voltage protection stages in electronic systems
• Clamping applications for signal or power lines

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging compatible with automated insertion equipment. Confirm the manufacturer designation as Microchip Technology to ensure compliance with specified quality standards. Cross-reference the DO-213AA footprint dimensions against the target PCB layout to guarantee mechanical fitment during assembly processes.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for an 8.2 V regulation task. Ensure the design accommodates the 500 mW power dissipation limit under worst-case thermal conditions. Verify that the 10% voltage tolerance aligns with the circuit's precision requirements and that the operating temperature range meets the environmental specifications.

Single Zener Diodes Part Context

This device belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology. While the base part number defines the electrical characteristics, the /TR suffix specifically denotes reel packaging for high-volume surface-mount production. This distinguishes it from bulk-packaged through-hole variants like the 1N5237B.
