1N4683/TR

Overview

The Microchip Technology 1N4683/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3 V with a tolerance of ±5%. The device operates in a through-hole DO-7 (DO-204AA) glass package and supports a maximum power dissipation of 500 mW. Electrical characteristics include a maximum reverse leakage current of 7.5 uA at the test current of 50 uA, a forward voltage of 1.1 V, and a maximum forward current of 200 mA. The component is rated for an operating temperature range from -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation with a nominal 3 V Zener breakdown voltage.
• Constructed with a hermetically sealed glass DO-7 axial leaded package.
• Capable of high-temperature operation up to +175°C for demanding environments.

Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging rather than bulk units when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the supplier provides official Microchip Technology datasheets to validate electrical parameters against design requirements before integration.

Selection Notes

Select this component when a 3 V regulation point is required within a through-hole assembly process. The DO-7 package accommodates standard PCB mounting techniques. Consider the 500 mW power rating for thermal management calculations. Verify that the ±5% voltage tolerance aligns with the circuit's precision requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the 1N4683 series of small-signal Zener diodes manufactured by Microchip Technology. The series utilizes silicon planar technology housed in glass axial packages. These components are engineered for general-purpose voltage regulation tasks where reliability and consistent performance across wide temperature ranges are essential for system stability.

Replacement Considerations

Cross-reference with Vishay Semiconductors 1N4683-TR or TAITRON Components Incorporated 1N4683 variants. Verify pinout compatibility and ensure equivalent Zener voltage and power dissipation ratings match the original design specifications before substitution.
