1N3822A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3822A-1/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage (Vz) of 3.6 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range of -65°C to +175°C. Key electrical parameters include a reverse leakage current of 75 µA at 1 V, a forward voltage of 1.2 V at 200 mA, and a maximum Zener impedance (Zzt) of 10 Ohms. It utilizes the DO-204AL (DO-41) axial through-hole package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 3.6 V breakdown voltage
• Capable of handling up to 1 W of power dissipation in a robust axial package
• Engineered for reliable operation across extreme temperatures from -65°C to +175°C
• Features low reverse leakage current and defined forward voltage characteristics

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 3.6 V levels
• Overvoltage protection stages in harsh environment electronics
• Power supply regulation modules operating under high thermal stress
• Military and aerospace systems adhering to MIL-PRF-19500/115 standards

Single Zener Diodes Procurement Notes

Verify that the specific suffix '-TR' confirms tape-and-reel packaging rather than bulk. Confirm compliance requirements, as this component typically does not meet RoHS directives due to its military-grade construction. Ensure the supplier provides traceability documentation consistent with MIL-PRF-19500/115 specifications for quality assurance.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V Zener diode is required for through-hole mounting in high-temperature environments. The DO-204AL package offers mechanical stability for axial leads. Consider the ±5% tolerance and 10 Ohm impedance limits against circuit sensitivity requirements. Verify availability of the reel format if automated assembly is planned.

Single Zener Diodes Part Context

This part belongs to the 1N3822 series of Zener diodes manufactured by Microchip Technology. It shares core electrical characteristics with variants like JANTX1N3822D-1 but differs in packaging and tolerance grades. The 'A' designation typically indicates a specific voltage bin or tolerance level within the broader 1N3822 family, while '-TR' denotes the reel packaging configuration.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3822A equivalents meeting MIL-PRF-19500/115. Cross-reference with JANTX1N3822C-1/TR for similar performance in reel packaging. Ensure any replacement matches the 3.6 V nominal voltage, 1 W power rating, and DO-204AL footprint.
