1N4687-TP

Overview

The MCC 1N4687-TP is a single silicon Zener diode housed in the DO-35 axial leaded package. It provides a nominal Zener voltage of 4.3 V with a standard tolerance of ±5%. The device supports a maximum steady-state power dissipation of 500 mW at a junction temperature up to 200 °C. Electrical characteristics include a maximum forward voltage of 1.5 V at 100 mA and a reverse leakage current of 4 µA measured at 2 V.

Feature Summary

• Features double slug type construction for high reliability
• Utilizes hermetically sealed glass encapsulation
• Provides very sharp reverse characteristic breakdown

Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Procurement Notes

Verify authenticity through authorized distributors due to counterfeiting risks. Confirm RoHS compliance status as the datasheet notes a lead-in-glass exemption. Ensure the ordering suffix matches the required packaging format, such as tape and reel or bulk, before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 4.3 V reference in an axial leaded form factor. Consider the 500 mW power rating and 200 °C thermal limits during circuit design. Verify that the ±5% voltage tolerance meets the specific precision requirements of the target application.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 1.8 V to 43 V within the same mechanical package family.

Replacement Considerations

Direct substitutes include the 1N4687-1E3 from Microchip Technology and the 1N749A BK PBFREE from Central Semiconductor Corp.
