1N5248BE3

Single Zener Diodes Overview

The 1N5248BE3 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features an 18 V nominal Zener voltage with a 5% tolerance and operates within a power dissipation rating of 500 mW. The device utilizes a DO-204AH-2 axial leaded package suitable for through-hole mounting. Electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 21 Ohms at a test current of 7 mA. It supports a wide operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with specified Zener voltage and tight tolerance accuracy.
• Features low reverse leakage current for efficient performance in high-resistance circuits.
• Constructed with a glass axial-leaded package for robust mechanical stability and thermal resistance.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation in power supplies

Single Zener Diodes Procurement Notes

Verify the specific suffix BE3 indicates RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package type matches the required PCB footprint, specifically the DO-204AH-2 form factor. Ensure the procurement channel provides official datasheets to validate the electrical parameters against design requirements before integration.

Single Zener Diodes Selection Notes

Select this component when an 18 V regulation point is required with standard 5% tolerance. The 500 mW power rating suits low-to-moderate current applications. Consider the extended temperature range up to 175°C for environments exceeding standard industrial limits. Verify that the axial lead configuration fits the assembly constraints compared to surface mount alternatives.

Single Zener Diodes Part Context

This part belongs to the widely used 1N52xx series of 0.5 W Zener diodes produced by Microchip Technology (formerly Microsemi). The series offers a broad selection of voltage values in standardized packages. The BE3 suffix typically denotes environmental compliance, distinguishing it from older non-compliant variants or military screening levels found in other series members.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 18 V Zener voltage, 500 mW power rating, and DO-204AH-2 package. Cross-reference with other manufacturers' 1N5248 equivalents ensuring identical electrical tolerances and thermal characteristics are maintained for circuit compatibility.
