1N5240/TR

Single Zener Diodes Overview

The 1N5240/TR is a single silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 10V with a tolerance range and operates within a power dissipation capacity of 500 mW. The component utilizes a DO-204AH (DO-35) glass axial-lead package suitable for through-hole mounting. It supports a wide operating temperature range from -65°C to +175°C junction temperature and is supplied in reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single silicon Zener junction
• Constructed in a hermetically sealed glass axial-lead package for durability
• Capable of operation across an extended industrial temperature range

Single Zener Diodes Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required tolerance levels and screening standards. Confirm RoHS compliance status as historical variants may differ. Check lead times and minimum order quantities directly with authorized distributors, as availability varies by region and production cycle.

Single Zener Diodes Selection Notes

Select this component when a standard 10V regulation point is required in a low-power through-hole design. Ensure the circuit can accommodate the specified 500 mW power dissipation at the maximum ambient temperature. Verify that the DO-35 package dimensions fit the PCB layout constraints and that the reverse leakage characteristics meet the system noise requirements.

Single Zener Diodes Part Context

This part belongs to the widely used 1N52xx series of 0.5-watt Zener diodes. The series offers a broad selection of voltage values from 2.4V to 200V in standard tolerances. The 'TR' suffix indicates tape and reel packaging, facilitating automated assembly processes compared to bulk or cut-tape options.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5240 equivalents in the DO-35 package. Cross-referencing should focus on matching the 10V nominal voltage, 500 mW power rating, and thermal performance specifications.
