1N4754AP/TR8

Overview

The 1N4754AP/TR8 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage (Vz) of 39V with a tolerance of +/- 5%. The device has a power dissipation rating of 1.0W and utilizes a DO-41-2 through-hole package. It is supplied in a reel format with a factory pack quantity of 1500 units.

Feature Summary

• Provides stable voltage regulation at a nominal 39V output level
• Capable of handling 1.0W power dissipation for robust performance
• Utilizes a standard DO-41-2 axial leaded package for through-hole mounting

Applications

• Voltage reference circuits requiring precise 39V levels
• Overvoltage protection in low-power electronic systems
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify the specific suffix TR8 indicates reel packaging when ordering. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the DO-41-2 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 39V Zener voltage with 5% tolerance is required. The 1.0W power rating suits applications exceeding standard 0.5W diode capabilities. The through-hole DO-41-2 package is appropriate for prototyping or environments where surface-mount technology is not feasible. Compare against other 1N47xx series variants if different voltage levels are needed.

Part Context

This part belongs to the 1N4754A family of Zener diodes produced by Microchip Technology. The 'AP' designation typically denotes specific manufacturing lot or quality attributes within the product line, while '/TR8' specifies the tape and reel packaging configuration. It falls under the broader category of discrete semiconductor diodes used for voltage control.

Replacement Considerations

Direct substitutes include other 1N4754A variants from different manufacturers offering identical 39V/1W specifications. Verify pinout compatibility and thermal characteristics when cross-referencing with generic 1N47xx series components. Ensure replacement parts meet the same voltage tolerance and package style requirements.
