1N4739A-TP

Overview

The MCC 1N4739A-TP is a silicon planar Zener diode housed in a DO-41 glass package. It provides a nominal voltage of 9.1 V with a 5% tolerance, rated for 1 W power dissipation at 50°C ambient temperature. The device operates within a junction temperature range of -65°C to +200°C and features a maximum dynamic impedance of 5 Ohms at the test current of 28 mA.

Feature Summary

• Utilizes a hermetic glass package for environmental stability
• Constructed using silicon planar technology
• Includes lead-free finish compliant with RoHS directives

Applications

• Voltage regulation circuits
• Reference voltage generation
• Surge protection applications

Procurement Notes

Verify component authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or bulk carton, prior to finalizing procurement orders.

Selection Notes

Select this component when a stable 9.1 V reference is required in through-hole designs. Ensure thermal derating is applied if operating above 50°C ambient temperature. Verify that the 5% voltage tolerance aligns with circuit requirements compared to standard 10% variants.

Part Context

This part belongs to the 1N4728 through 1N4761 series of 1.0 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V, utilizing a standardized DO-41G axial leaded package suitable for general-purpose discrete semiconductor applications.

Replacement Considerations

The 1N4739AP-TP serves as an alternative variant from the same manufacturer.
