1N4690E3/TR

Overview

The Microchip Technology 1N4690E3/TR is a single silicon 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 a DO-35 (DO-204AH) through-hole package, dissipating up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 10 µA and a forward voltage of 1.5 V at 100 mA. It supports a wide operating temperature range from -65 °C to +175 °C and is supplied in a reel format.

Feature Summary

• Provides stable voltage regulation using a single unidirectional Zener junction.
• Constructed with hermetically sealed glass encapsulation for environmental protection.
• Capable of operation across an extended industrial temperature range.

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clamping applications

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the DO-35 through-hole footprint matches the target PCB design. Cross-reference the exact part number with the latest datasheet to confirm pinout and thermal characteristics before finalizing procurement.

Selection Notes

Select this component for designs requiring a precise 5.6 V reference with high-temperature resilience. The DO-35 package suits standard through-hole manufacturing processes. Evaluate the 500 mW power dissipation limit against expected surge currents. Consider the ±5% voltage tolerance for circuit accuracy requirements. Verify that the low leakage current meets the sensitivity needs of the application.

Part Context

This part belongs to the 1N4690 series of Zener diodes manufactured by Microchip Technology. It is a lead-free, RoHS-compliant variant of the traditional 1N4690 specification. The device is categorized under discrete semiconductor diodes and rectifiers. It serves as a direct replacement for older non-compliant versions while maintaining identical electrical performance and mechanical dimensions.

Replacement Considerations

The 1N4690 is the primary historical equivalent. Other manufacturers produce compatible parts such as Vishay MMSZ4690-E3-08. Verify package compatibility and voltage tolerance when substituting. Ensure the replacement device meets the same thermal and power dissipation specifications.
