1N5245D-1

Single Zener Diodes Overview

The Microchip Technology 1N5245D-1 is a single silicon Zener diode designed for through-hole mounting in the DO-204AH (DO-35) glass axial package. It features a nominal Zener voltage of 15 V with a tight tolerance of ±1%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65 °C to +200 °C. Key electrical characteristics include a test current of 8.5 mA, a maximum reverse leakage current of 100 nA, and a Zener impedance of 16 Ohms.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±1% tolerance
• Extended high-temperature operation up to 200 °C
• Hermetically sealed glass axial construction

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection in sensitive electronics
• Clamping applications in high-reliability systems

Single Zener Diodes Procurement Notes

Verify the specific suffix D-1 confirms the ±1% tolerance variant, as standard 1N5245B parts typically have 5% tolerance. Confirm RoHS compliance status and lead times directly with authorized distributors or Microchip, as availability varies by region and production cycle. Ensure the DO-35 package matches your PCB footprint requirements.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required compared to standard 5% tolerance Zener diodes. The high operating temperature rating makes it suitable for harsh environments where standard silicon devices might fail. Consider the physical size of the DO-35 package against available board space and thermal management needs.

Single Zener Diodes Part Context

This part belongs to the 1N5245 series of low-power Zener diodes manufactured by Microchip Technology. The series offers various tolerance grades, with the D-1 suffix denoting the high-precision ±1% version. These diodes are commonly used in military, aerospace, and industrial applications requiring reliable voltage regulation in small axial packages.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5245D-1 variants or equivalent 15V Zener diodes with ±1% tolerance and 500mW power rating in DO-35 packages. Verify that replacement parts match the specific Zener impedance and leakage current specifications if circuit sensitivity is critical.
