1N4475 TR TIN/LEAD

Single Zener Diodes Overview

The 1N4475 TR TIN/LEAD is a silicon unidirectional Zener diode manufactured by Central Semiconductor Corp. It features a nominal reference voltage of 27 V and a maximum power dissipation of 1.5 W. The component utilizes a DO-41 axial through-hole package with isolated case connection. It is supplied in tape and reel packaging and contains lead, indicating non-RoHS compliance.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics at the specified nominal voltage.
• Constructed from silicon material for reliable semiconductor performance.
• Designed for through-hole mounting using the standard DO-41 axial leaded package.

Single Zener Diodes Applications

• Voltage regulation circuits requiring a fixed reference potential.
• Overvoltage protection for sensitive electronic components.
• Clipping and clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify that the specific procurement order includes the tin/lead plating variant, as this affects RoHS compliance status. Confirm the tape and reel packaging format matches automated assembly requirements. Ensure the 1.5 W power rating and 27 V Zener voltage align precisely with the circuit design specifications before finalizing the purchase order.

Single Zener Diodes Selection Notes

Select this component when a 27 V Zener voltage with 1.5 W power handling is required in an axial package. The tin/lead finish is suitable for traditional soldering processes but requires consideration for environmental regulations. Verify compatibility with existing PCB footprints designed for the DO-41 form factor during the design phase.

Single Zener Diodes Part Context

This part belongs to the 1N4475 series of Zener diodes produced by Central Semiconductor Corp. The series offers various voltage options within the same physical DO-41 package family. The 'TR' suffix denotes tape and reel packaging, while 'TIN/LEAD' specifies the terminal finish, distinguishing it from lead-free or bulk packaged variants.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4475 equivalents in DO-41 packages. Ensure substitute parts match the 27 V nominal voltage, 1.5 W power rating, and unidirectional configuration. Verify that alternative suppliers provide compatible tin/lead terminations if RoHS exemption is necessary.
