1N4736A-TP

Overview

The MCC 1N4736A-TP is a silicon planar Zener diode housed in a DO-41 glass package. It provides a nominal Zener voltage of 6.8 V with a ±5% tolerance and a maximum power dissipation of 1.0 W at 50°C ambient temperature. The device features a maximum reverse leakage current of 10 µA at 4 V, a forward voltage drop of 1.2 V at 200 mA, and a dynamic impedance of 3.5 Ω at the test current of 37 mA. It operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Encased in a hermetic glass package for environmental protection
• Compliant with RoHS standards and lead-free finish

Applications

• DC power supply voltage regulation
• Voltage reference circuits
• Overvoltage protection

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the component meets specific quality standards for handling and storage. Ensure the application does not involve life support devices without express written approval from the manufacturer.

Selection Notes

Select this component when a precise 6.8 V reference is required with tight tolerance. Consider the thermal resistance characteristics and derating requirements for capacitive loads. Verify that the operating environment falls within the specified temperature limits and that the package style matches the circuit board design.

Part Context

This part belongs to the 1N4728 through 1N4761 series of 1.0 Watt Zener diodes manufactured by Micro Commercial Components. The 'A' suffix indicates a 5% voltage tolerance, distinguishing it from standard versions. The '-TP' suffix denotes tape and reel packaging availability.

Replacement Considerations

Substitutes must match the 6.8 V Zener voltage, 1.0 W power rating, and DO-41 package. Verify that alternative components meet the same electrical specifications for leakage current and dynamic impedance to ensure circuit performance consistency.

FAQ

What is the voltage tolerance for the 1N4736A-TP?

The 'A' suffix indicates a 5% tolerance on the nominal Zener voltage.

How is the Zener impedance measured?

It is derived from the 60 Hz AC voltage resulting when an AC current equal to 10% of the DC Zener current is superimposed on the DC current.
