1N4690-TP

Overview

The MCC 1N4690-TP is a silicon Zener diode with a nominal voltage of 5.6 V and a tolerance of ±5%. It features a maximum steady-state power dissipation of 500 mW at a lead temperature below 75°C, with a junction temperature rating of 200°C. The device operates in the DO-35 axial-leaded package and exhibits a maximum forward voltage of 1.5 V at 100 mA. Reverse leakage current is specified as 10 µA at 4 V.

Feature Summary

• Hermetically sealed glass construction with double slug type case
• Very sharp reverse characteristic for precise regulation
• Lead-free finish compliant with RoHS3 standards

Applications

• Voltage regulation over broad operating currents
• Protection against voltage transients
• Reference voltage generation in electronic circuits

Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or authorized distributors to ensure traceability and quality standards. Confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or bulk, as these affect handling procedures. Ensure compliance with environmental directives applicable to your region before finalizing procurement.

Selection Notes

Select this component when a standard 5.6 V reference is required within a through-hole design. Consider the 500 mW power limit and 200°C junction temperature capability for thermal management. Verify that the DO-35 package dimensions align with the target PCB layout constraints and that the ±5% tolerance meets the circuit's precision requirements.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes manufactured by Micro Commercial Components. The series provides a wide range of voltages from 1.8 V to 43 V in the same DO-35 package family. The -TP suffix specifically indicates availability in tape and reel packaging for automated assembly processes.
