1N4736AG

Overview

The 1N4736AG is a single silicon planar power Zener diode manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 4 V and a Zener impedance of 3.5 Ohms. It utilizes the DO-204AL (DO-41) through-hole package.

Feature Summary

• Hermetically sealed glass construction for environmental stability
• Designed for stabilizing and clipping circuits with high power rating
• Silicon planar technology ensures reliable performance

Applications

• Voltage regulation in power supplies
• Clipping circuits for signal conditioning
• Reference voltage sources in electronic systems

Procurement Notes

Verify the manufacturer designation, as Microsemi Corporation was acquired by Microchip Technology. Ensure the ordering suffix matches the required packaging configuration, such as bulk or tape and reel, as these affect handling but not the electrical function. Confirm RoHS compliance status if restricted substances are a constraint for your specific assembly process.

Selection Notes

Select this component when a stable 6.8 V reference is required in through-hole designs. The 1 W power rating supports moderate current applications. Consider the ±5% tolerance for precision requirements. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical for circuit reliability.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes, widely used for voltage regulation. The 'AG' suffix typically denotes specific testing or packaging variations within the Microsemi/Microchip portfolio. These diodes are fundamental components in analog electronics for maintaining constant voltage levels across varying load conditions.

Replacement Considerations

Equivalent parts include Vishay 1N4736A and other manufacturers offering 6.8 V, 1 W Zener diodes in the DO-41 package. Verify pinout compatibility and ensure thermal derating curves align with your application's ambient temperature constraints before substitution.
