1N4755AE3/TR13

Overview

The Microchip Technology 1N4755AE3/TR13 is a single silicon Zener diode housed in the DO-204AL (DO-41) axial leaded package. It features a nominal Zener voltage of 43 V with a tolerance of +/- 5%. The device has a power dissipation rating of 1 W and operates within a temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse leakage current of 5 uA, a test current of 6 mA, and a Zener impedance of 70 Ohms. The component is RoHS compliant and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation at a nominal 43 V level for circuit protection and reference applications.
• Capable of handling 1 W power dissipation in an axial through-hole package for robust mounting.
• Operates reliably across an extended industrial temperature range from -65°C to +200°C.

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the TR13 designation indicates tape and reel supply. Confirm manufacturer origin, as this part number may be sourced from Microchip or its acquired entities like Microsemi. Ensure compliance requirements such as RoHS are met for your specific assembly process. Cross-reference datasheets for exact thermal and electrical limits before finalizing procurement specifications.

Selection Notes

Select this component when a 43 V Zener voltage with 5% tolerance is required in a standard axial package. Consider the 1 W power rating and high operating temperature limit of +200°C for demanding environments. Compare against similar parts like the 1N4755A if bulk packaging is preferred over the TR13 reel format. Verify that the 70 Ohm impedance meets the dynamic regulation needs of the target application.

Part Context

This part belongs to the 1N47xx series of Zener diodes, widely used for general-purpose voltage regulation. The 'e3' suffix denotes lead-free composition, adhering to modern environmental standards. The TR13 suffix specifies the reel quantity and packaging style, distinguishing it from bulk variants like the 1N4755A. It is functionally equivalent to other industry-standard 43V 1W Zener diodes in the DO-41 package.

Replacement Considerations

The 1N4755A is a compatible alternative offering identical electrical specifications but typically available in bulk packaging rather than tape and reel. Other manufacturers produce equivalent 43V 1W Zener diodes in the DO-41 package, provided they meet the same voltage tolerance and temperature ratings.
