1N5260B

Single Zener Diodes Overview

The Microchip Technology 1N5260B is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a standard tolerance of 5%. The device operates in a through-hole DO-7 (DO-35) glass axial-lead package and supports a maximum power dissipation of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 93 Ohms at a test current of 3 mA, and a forward voltage of 1.1 V. The component maintains a stable operation across an extended temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation utilizing a 43 V Zener breakdown characteristic within a compact glass axial-lead package.
• Engineered for high thermal stability, supporting continuous operation up to a junction temperature of 200 °C.
• Ensures low leakage performance with a maximum reverse current rating of 100 nA under specified conditions.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific manufacturer suffix or revision code when sourcing replacements, as legacy production lines may vary. Confirm that the DO-7 package dimensions align with existing PCB footprints. Ensure the procurement channel provides original manufacturer documentation to validate the 5% voltage tolerance and 500 mW power rating specifications before integration into final designs.

Single Zener Diodes Selection Notes

Select this component when a 43 V regulation point is required in a through-hole configuration. The 500 mW power rating suits moderate current applications where higher wattage devices are unnecessary. Consider the 93 Ohm impedance value for dynamic load analysis. The wide operating temperature range makes it suitable for industrial environments exceeding standard commercial limits.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xx series of Zener diodes, a standard JEDEC registration utilized globally for decades. The 1N5260B specifically addresses the 43 V segment of this family. Manufactured by Microchip Technology, it continues the lineage of reliable discrete semiconductor components originally established by predecessor companies such as Philips Semiconductors.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the MSP1N5260B from Microsemi, which offers hermetic sealing in the same DO-7 package. Other generic equivalents must match the 43 V Zener voltage, 500 mW power dissipation, and DO-35/DO-7 form factor to ensure functional interchangeability without circuit modification.
