1N3825A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3825A-1/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and operates within a temperature range of -65°C to +175°C. Key electrical specifications include a maximum reverse leakage current of 5 µA and a Zener impedance of 8 Ohms. It is housed in the DO-204AL (DO-41) through-hole package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 4.7 V level
• Capable of handling 1 W power dissipation for robust performance
• Engineered for high-temperature operation up to 175°C
• Utilizes a standard DO-204AL axial leaded package for easy integration

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 4.7 V levels
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths
• Power supply regulation modules

Single Zener Diodes Procurement Notes

Verify the specific suffix -1/TR confirms the tape-and-reel packaging format when ordering. Confirm that the ±5% tolerance aligns with circuit requirements, as tighter tolerances may require alternative part numbers. Ensure the DO-204AL package dimensions fit the designated PCB footprint. Cross-reference the manufacturer's latest datasheet for any updates on compliance or environmental certifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 1 W power rating and 4.7 V regulation are required. The wide operating temperature range makes it suitable for industrial environments. Consider the 8 Ohm impedance for dynamic load conditions. Verify that the through-hole mounting style matches the assembly process. Compare against other Zener voltages if the system requires different reference levels.

Single Zener Diodes Part Context

This part belongs to the family of single silicon Zener diodes manufactured by Microchip Technology. It shares the same core die and electrical characteristics as the non-tape variant but differs in packaging configuration. The DO-41 package is a standard industry form factor for axial leaded diodes. This series is commonly used in discrete semiconductor applications where reliability and thermal stability are critical.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers include JAN1N3825A-1C from VPT Inc, which offers identical 4.7 V Zener voltage and DO-41 package compatibility.
