1N4754G R0G

Overview

The 1N4754G R0G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 39V with a 5% tolerance and a power dissipation rating of 1W. The device utilizes a DO-41 glass axial leaded package designed for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5µA at the rated voltage and a test current of 25mA. The component operates within a temperature range of -65°C to +175°C.

Feature Summary

• Hermetically sealed glass compression bonded construction
• Corrosion resistant external surfaces
• Terminals readily solderable per MIL-STD-208

Applications

• Voltage regulation in electronic circuits
• Voltage reference applications
• Protection against overvoltage conditions

Procurement Notes

Verify RoHS compliance status as suffixes may vary. Confirm exact packaging quantity and reel specifications with the manufacturer or authorized distributor before ordering. Ensure the specific part number matches the required voltage tolerance and package type for your design.

Selection Notes

Select this component for designs requiring a stable 39V reference with high reliability. The hermetically sealed glass package offers superior performance in harsh environments compared to plastic equivalents. Verify thermal management requirements for continuous operation near the maximum power dissipation limit.

Part Context

This part belongs to the standard 1N47xx series of 1W Zener diodes widely used in general-purpose electronics. The 'G' suffix typically indicates RoHS compliance, while the 'R0G' designation specifies the specific tape and reel packaging configuration provided by Taiwan Semiconductor.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4754 variants. Ensure replacement parts match the 1W power rating, DO-41 package dimensions, and 39V Zener voltage tolerance. Verify that any substitute meets the same thermal and electrical specifications.
