1N4691/TR

Overview

The Microchip Technology 1N4691/TR is a single silicon Zener diode housed in a DO-7 (DO-35) through-hole package. It provides a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device features a maximum power dissipation of 500 mW and a maximum reverse leakage current of 10 µA at 5 V. It operates within a temperature range of -65 °C to +175 °C and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Constructed from silicon material for reliable semiconductor performance
• Designed for through-hole mounting in standard axial lead configurations

Applications

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

Procurement Notes

Verify the specific manufacturer datasheet for the 1N4691/TR variant, as specifications such as tolerance and leakage may vary between production sources. Confirm that the DO-7 package and tape-and-reel delivery format align with your assembly requirements. Ensure compliance with any applicable environmental regulations relevant to your deployment region.

Selection Notes

Select this component when a 6.2 V reference is needed in a through-hole axial package. The 500 mW power rating supports moderate current applications. Verify that the ±5% voltage tolerance meets your circuit precision requirements. Consider the operating temperature range if the environment exceeds standard commercial limits.

Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes the JEDEC DO-7 case outline, which is compatible with legacy DO-35 footprints. The /TR suffix indicates tape-and-reel packaging for automated insertion processes.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4691 designation in DO-35/DO-7 packages. Verify pinout compatibility and thermal characteristics before substitution.
