1N4755UR-1

Overview

The Microchip Technology 1N4755UR-1 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a tolerance of ±10%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +175 °C. It is housed in a surface-mount DO-213AB (MELF, LL41) package.

Feature Summary

• Provides stable voltage regulation at 43 V
• Supports high-temperature operation up to 175 °C
• Utilizes a compact MELF surface-mount package

Applications

• Voltage reference circuits
• Over-voltage protection
• Clamping applications

Procurement Notes

Verify component authenticity through authorized distributors or official Microchip channels. Confirm the specific suffix and package type matches design requirements. Check for RoHS compliance status as indicated by manufacturer documentation. Ensure storage conditions align with semiconductor handling standards to prevent damage prior to assembly.

Selection Notes

Select this component when a 43 V regulation point is required in a surface-mount layout. Consider the 1 W power rating and extended temperature range for harsh environments. Compare against through-hole equivalents if board space permits alternative packaging solutions.

Part Context

This part belongs to the Microchip Technology single Zener diode family. It serves as a surface-mount alternative to traditional axial leaded regulators. The MELF package offers reliability advantages for automated assembly processes in industrial and commercial electronics.
