1N5247CE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N5247CE3/TR is a single Zener diode with a nominal voltage of 17 V and a power dissipation rating of 500 mW. It features a tight tolerance of ±2% and operates within a temperature range of -55 °C to +175 °C. The device utilizes a DO-35 axial leaded package and exhibits a maximum reverse leakage current of 100 nA at the rated voltage.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance for sensitive circuit applications
• Engineered for high-temperature reliability with an extended operating range up to 175 °C
• Utilizes a hermetically sealed glass axial package for robust environmental protection

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix CE3/TR against your bill of materials, as it denotes RoHS compliance and tape-and-reel packaging. Confirm that the ±2% tolerance variant meets your design requirements, as standard versions may differ. Ensure the DO-35 through-hole package fits your PCB layout constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is critical, given its ±2% tolerance compared to standard 5% variants. The high-temperature rating makes it suitable for automotive or industrial environments where thermal stability is essential. Consider the axial lead form factor for manual assembly or legacy board designs requiring through-hole mounting.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of low-power Zener diodes manufactured by Microchip Technology. It serves as a precision-regulation alternative to general-purpose diodes, offering superior stability. The CE3 designation indicates compliance with environmental standards, while TR specifies reel packaging for automated insertion.

Single Zener Diodes Replacement Considerations

The 1N5247B-TP from Micro Commercial Components is a functional substitute but carries a wider 5% tolerance instead of the required ±2%. Verify if the relaxed tolerance is acceptable for your application. Other generic 17V Zener diodes in DO-35 packages may match electrical specs but lack the specific high-temperature certification.
