1N5262

Single Zener Diodes Overview

The Microchip Technology 1N5262 is a silicon Zener voltage regulator diode designed for through-hole mounting in the DO-204AH (DO-35) axial leaded package. It provides a nominal Zener voltage of 51 V with a maximum power dissipation of 500 mW. The device features a test current of 2.5 mA and maintains an operating temperature range from -65 °C to +175 °C junction temperature. Electrical characteristics include a maximum reverse leakage current of 100 nA at 39 V and a Zener impedance of 125 ohms.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction utilizing double slug type metallurgical bonding for environmental stability.
• Capable of regulating voltage across a broad operating current and temperature range.
• Axial leaded package design offers a smaller footprint compared to conventional DO-204AA configurations.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits requiring stable reference potentials.
• Overvoltage protection for sensitive semiconductor components.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required for the application, as standard variants typically carry a 'B' designation for 5% tolerance. Confirm RoHS compliance status, as historical manufacturing data indicates variations between compliant and non-compliant versions depending on the production era and specific ordering suffix. Ensure the procurement channel sources authentic Microchip Technology components to guarantee specified electrical parameters.

Single Zener Diodes Selection Notes

Select this component when a 51 V reference is needed in a through-hole assembly. The 500 mW rating supports moderate current loads. Verify that the circuit's thermal environment allows operation up to 175 °C junction temperature. Consider the 125 ohm impedance for dynamic regulation requirements. For surface mount equivalents, consult the 1N5221BUR-1 series documentation.

Single Zener Diodes Part Context

This part belongs to the widely utilized 1N5221 through 1N5281 series of 500 mW Zener diodes. The series covers a voltage range from 2.4 V to 200 V. The 1N5262 specifically addresses the 51 V segment of this lineup. It serves as a standard discrete solution for general-purpose voltage regulation tasks in industrial and commercial electronics.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the 1N5221BUR-1 series within the DO-213AA package. Cross-manufacturer replacements must match the 51 V Zener voltage, 500 mW power rating, and DO-204AH package dimensions. Verify tolerance specifications align with circuit requirements before substitution.
