1N4690/TR

Overview

The Microchip Technology 1N4690/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device operates in the DO-7 (DO-204AA) axial-leaded package, suitable for through-hole mounting. It supports a maximum power dissipation of 500 mW and maintains functionality across an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 4 V and a forward voltage of 1.1 V at 200 mA.

Feature Summary

• Provides stable voltage regulation over a broad operating current and temperature range
• Constructed with glass axial-leaded DO-35 body for durability
• Offers guaranteed maximum voltage regulation performance

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify the specific suffix designation against official documentation to confirm packaging configuration. The /TR suffix typically indicates reel packaging, which may differ from bulk options available for other variants in the same series. Confirm RoHS compliance status as standard versions in this series may not meet current environmental directives. Ensure the selected part number matches the required lead frame and marking specifications for your assembly process.

Selection Notes

Select this component when a 5.6 V regulation point is required within a low-power design. The DO-7 package accommodates standard through-hole manufacturing techniques. Consider the thermal environment carefully, as the device supports high-temperature operation up to 175°C. Verify that the circuit current remains within the safe operating area defined by the 500 mW power dissipation limit.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 0.5 W Zener Voltage Regulators manufactured by Microchip Technology. The series provides a wide selection of voltages ranging from 1.8 V to 43 V. These components are standardized JEDEC registered devices, ensuring compatibility with established industry designs and replacement requirements.

Replacement Considerations

Equivalent parts include 1N4690, 1N4690C, and 1N4690DUR-1. Verify package type and tolerance requirements when substituting, as variations exist between axial-leaded and surface-mount versions.
