1N4741G R0G

Overview

The 1N4741G R0G is a Zener diode manufactured by Taiwan Semiconductor Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 11V with a tolerance of ±5%. The device is housed in a DO-41 glass axial leaded package and supports a maximum power dissipation of 1W. It operates within a temperature range from -65°C to +175°C. The component utilizes hermetically sealed glass compression bonded construction and complies with RoHS standards.

Feature Summary

• Hermetically sealed glass compression bonded construction
• Corrosion resistant external surfaces
• Readily solderable pure tin plated terminals

Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure compliance with project requirements. Confirm that the received components match the 1N4741G R0G designation and packaging specifications. Inspect leads for straightness and cleanliness before assembly. Ensure storage conditions prevent moisture absorption or physical damage during handling and transportation processes.

Selection Notes

Select this component when a stable 11V reference is required in through-hole designs. The DO-41 glass package offers high reliability and thermal stability compared to plastic alternatives. Consider the ±5% tolerance for precision applications. Verify that the 1W power rating aligns with the expected current draw and ambient operating temperatures of the target circuit design.

Part Context

This part belongs to the 1N47XX series of Zener diodes produced by Taiwan Semiconductor. The 'G' suffix typically denotes a glass passivated junction, while 'R0G' indicates reel packaging. These devices are widely used in industrial and consumer electronics where robust voltage clamping is necessary. The series covers a broad range of voltages from 3.3V to 56V.

Replacement Considerations

Compatible substitutes include the 1N4741A from other manufacturers such as Microchip or EIC, provided they meet the same 11V, 1W, and DO-41 package specifications. Ensure any replacement maintains the hermetic seal and thermal characteristics if environmental resistance is critical.
