1N4755AP/TR8

Overview

The Microchip Technology 1N4755AP/TR8 is a single silicon Zener diode housed in the DO-41 axial through-hole package. It provides a nominal Zener voltage of 43 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and features a maximum reverse leakage current of 5 µA.

Feature Summary

• Provides stable voltage regulation at a nominal 43 V level
• Constructed using silicon technology for reliable performance
• Designed for axial through-hole mounting configurations

Applications

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

Procurement Notes

Verify the specific suffix TR8 to confirm reel packaging requirements. Ensure the component matches the 1N4755APE3 designation if RoHS compliance is mandatory for the assembly process. Cross-reference datasheets to confirm electrical parameters align with design specifications before procurement.

Selection Notes

Select this component when a 43 V regulation point is required within a 1 W power budget. The DO-41 package suits standard through-hole manufacturing processes. Verify that the ±5% tolerance meets circuit accuracy needs, as tighter tolerances require alternative part numbers within the series.

Part Context

This component belongs to the 1N47xx series of high-power Zener diodes manufactured by Microchip Technology. The series covers a wide range of voltage ratings from 3.3 V to 200 V, all sharing similar physical dimensions and thermal characteristics suitable for robust industrial applications.

Replacement Considerations

The 1N4755A is the non-RoHS equivalent. The 1N4755Ce3 offers a tighter ±2% tolerance. Other manufacturers produce pin-compatible equivalents under the same 1N4755 designation.
