1N4691-TP

Overview

The 1N4691-TP is a 500mW silicon Zener diode in a DO-35 glass package. It features a nominal Zener voltage of 6.2V with a standard tolerance of ±5%. The device operates within a junction temperature range up to 200°C and includes a maximum forward voltage of 1.5V at 100mA. It exhibits a sharp reverse characteristic and high reliability, suitable for general-purpose voltage regulation applications.

Feature Summary

• Hermetically sealed double slug glass construction
• Sharp reverse breakdown characteristic
• Lead-free finish and RoHS compliant

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipper and clamper circuits

Procurement Notes

Verify the specific ordering suffix (TP) corresponds to tape and reel packaging containing 10,000 pieces per reel. Confirm compliance with EU Directive Annex 7(C)-I regarding lead in glass exemption. Ensure procurement from authorized distributors to guarantee authenticity and traceability, as MCC does not warrant parts from unauthorized sources.

Selection Notes

Select this component when a 6.2V Zener voltage with ±5% tolerance is required in a compact DO-35 axial leaded package. Consider the 500mW power dissipation limit and thermal resistance of 300 K/W for heat management. Verify that the operating current stays within the specified maximum Zener current rating of 5.0mA for optimal performance.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers Zener voltages ranging from 1.8V to 43V. The 1N4691 specifically addresses the 6.2V segment of this range, utilizing the same DO-35 hermetic glass package design common to the family.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4691 equivalents meeting the same electrical specifications and DO-35 package dimensions. Verify that any replacement maintains the 500mW power rating and ±5% voltage tolerance to ensure circuit compatibility.
