1N3824A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3824A-1/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.3 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates in the through-hole DO-204AL (DO-41) package. Key electrical characteristics include a leakage current of 5 µA and a maximum forward voltage of 1.2 V. The component is supplied in reel and tape packaging, suitable for automated assembly processes.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 4.3 V level
• Capable of handling up to 1 W of power dissipation
• Constructed using silicon technology for reliable performance
• Available in standard through-hole DO-204AL axial leaded package

Single Zener Diodes Applications

• General purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required environmental standards or hermetic sealing needs. Confirm that the DO-204AL package dimensions match the target PCB footprint. Check for RoHS compliance status if restricted substances are prohibited in the final assembly. Ensure the reel quantity matches the production line requirements.

Single Zener Diodes Selection Notes

Select this component when a precise 4.3 V reference is required in a through-hole design. The 1 W power rating allows for moderate current handling without excessive heat sinking. Consider the ±5% tolerance for applications requiring tight voltage accuracy. Evaluate thermal management strategies based on the expected operating current and ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the 1N3824 series of compensated Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the low-voltage range, providing consistent performance across different regulatory designs. The -1/TR suffix indicates the specific voltage grade and tape-and-reel packaging format for efficient manufacturing integration.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JAN1N3824A-1/TR and JANTXV1N3824A-1 from Microchip, which share identical electrical specifications but may differ in military-grade qualification or packaging variations. Cross-brand replacements must match the 4.3 V Zener voltage, 1 W power rating, and DO-204AL package form factor.
