1N5263A-1

Single Zener Diodes Overview

The Microchip Technology 1N5263A-1 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 56 V with a tolerance of 10%. The device is rated for a maximum power dissipation of 0.48 W and utilizes a DO-35 glass axial-lead package. It operates within a temperature range of -65°C to +200°C and is classified as a single unidirectional voltage regulator diode.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 56 V level
• Constructed in a hermetically sealed glass axial-lead package
• Capable of operation up to a junction temperature of 200°C

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Biasing networks

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A-1' against official Microchip documentation, as standard listings often use '1N5263'. Confirm RoHS compliance status, as older or military-grade variants may not meet current environmental standards. Ensure the required 10% tolerance aligns with design specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 56 V regulation point is required in a through-hole axial configuration. Consider the 0.48 W power rating and thermal management needs. Verify if the 10% tolerance meets circuit precision requirements compared to tighter tolerance alternatives like the 'B' suffix series.

Single Zener Diodes Part Context

This part belongs to the widely used 1N52xx series of low-power Zener diodes manufactured by Microchip Technology (formerly Microsemi). These components are standard discrete semiconductors utilized in general-purpose electronic designs requiring reliable voltage clamping or reference functions in compact packages.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent substitutes include the 1N5263 and 1N5263B from Microchip. Other manufacturers producing JEDEC-standard 1N5263 devices in DO-35 packages may also serve as functional replacements.
