1N4728G R0G

Single Zener Diodes Overview

The Taiwan Semiconductor Corporation 1N4728G R0G is a silicon Zener diode designed for voltage regulation and clipping applications. It features a nominal Zener voltage of 3.3V with a tolerance of ±5%. The device is housed in the DO-41 glass axial leaded package, suitable for through-hole mounting. It supports a maximum power dissipation of 1W at an ambient temperature of 25°C. The component operates within a junction temperature range of -65°C to +175°C and utilizes compression bonded construction with a hermetically sealed glass case.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction with compression bonded design
• Corrosion-resistant external surfaces and solderable pure tin plated terminals
• Oxide passivated die for enhanced reliability

Single Zener Diodes Applications

• Voltage stabilization circuits
• Signal clipping applications
• General purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'R0G' corresponds to the specific tape and reel packaging configuration rather than altering the electrical characteristics. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the supplier provides documentation confirming the ±5% tolerance grade associated with the 'G' suffix.

Single Zener Diodes Selection Notes

Select this component when a standard 3.3V reference is required in through-hole designs. The DO-41 package offers robust mechanical stability compared to smaller surface-mount alternatives. Consider the ±5% tolerance limits if high precision is needed; otherwise, tighter tolerance variants like the 1N4728C are appropriate.

Single Zener Diodes Part Context

This part belongs to the 1N47XXG series of 1W Zener diodes from Taiwan Semiconductor. The series covers a wide voltage range from 3.3V to 56V. The 'G' designation typically indicates a ±5% voltage tolerance, distinguishing it from higher precision or lower tolerance variants within the same physical package family.

Single Zener Diodes Replacement Considerations

Equivalent parts include Vishay 1N4728A and onsemi 1N4728A. These devices share identical electrical ratings and the DO-41 glass package, allowing for direct pin-to-pin substitution in existing circuit layouts.
