1N5260A

Single Zener Diodes Overview

The Microchip Technology 1N5260A is a 43 V Zener diode housed in a DO-7 glass axial-lead package. It features a maximum power dissipation of 500 mW and a voltage tolerance of ±10%. The device operates within a temperature range of -65°C to +200°C, with a test current of 3 mA. Key electrical parameters include a maximum reverse leakage current of 100 nA at 39 V, a Zener impedance of 93 Ohms, and a voltage temperature coefficient of +0.095 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features minimal capacitance characteristics suitable for high-frequency applications.
• Constructed with a hermetically sealed glass body for environmental protection.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection systems
• Clipping and clamping circuits

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as historical data indicates production by Microsemi (now Microchip Technology). Confirm compliance with RoHS standards if required, noting that standard versions may differ from e3 suffix variants. Ensure the ordering suffix matches the desired tolerance level and packaging format before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 43 V breakdown voltage with 10% tolerance is required in an axial-lead package. Consider the positive temperature coefficient for thermal stability requirements. Evaluate the 500 mW power rating against circuit load conditions to ensure operation remains within safe derating curves.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V in standard DO-35 packages. The 1N5260A specifically addresses mid-range voltage regulation needs within this established product line.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5259A and 1N5261A for adjacent voltage ratings. Cross-manufacturer equivalents exist but require verification of pinout compatibility and thermal resistance specifications.
