1N5247A

Single Zener Diodes Overview

The Microchip Technology 1N5247A is a through-hole Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 17 V with a 10% tolerance and a maximum power dissipation of 500 mW. The device utilizes a DO-35 glass axial leaded package, supporting an operating temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 1 µA at the rated voltage and a Zener impedance of 18 Ohms measured at a test current of 14.5 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within a specified tolerance band
• Capable of operation in extreme high-temperature environments up to 200 °C
• Constructed with a hermetically sealed glass axial leaded package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin configuration prior to assembly. Ensure compliance with relevant environmental directives applicable to your specific deployment region. Cross-reference ordering information directly with authorized distribution channels to guarantee supply chain validity.

Single Zener Diodes Selection Notes

Select this component when a 17 V regulation point is required in a standard through-hole design. The 500 mW power rating suits moderate current applications. Verify that the thermal environment remains within the specified -65 °C to +200 °C operational limits. Consider the DO-35 package dimensions for PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the industry-standard 1N52xx series of silicon Zener diodes manufactured by Microchip Technology. These components are widely utilized in discrete electronic designs requiring reliable voltage clamping or referencing. The 1N5247A specifically addresses the 17 V segment of this extensive product family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5247B variant, which offers tighter voltage tolerance. Other manufacturers produce equivalent parts under the same JEDEC designation, provided they meet the 500 mW power and 17 V Zener voltage specifications.
