1N4751G R0G

Overview

The Taiwan Semiconductor 1N4751G R0G is a single-channel Zener voltage regulator diode designed for through-hole mounting in the DO-41 package. It features a nominal Zener voltage of 30 V with a 5% tolerance and a maximum power dissipation of 1 W. The device operates within a temperature range of -65°C to +200°C, with a test current of 8.5 mA, a maximum Zener impedance of 40 Ω, and a maximum reverse leakage current of 5 μA.

Feature Summary

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

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status and specific suffix requirements for your application. Ensure the supplier provides traceability documentation to guarantee the integrity of the hermetically sealed glass construction.

Selection Notes

Select this component when a stable 30 V reference is required in high-temperature environments up to 200°C. The DO-41 through-hole package facilitates easy integration into standard PCB layouts. Consider the 1 W power rating and 40 Ω impedance for appropriate circuit design margins.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Taiwan Semiconductor. The 'G' suffix typically indicates RoHS compliance, while 'R0G' specifies the Ammo Pack packaging format. These devices are widely used in general-purpose electronic applications requiring reliable voltage regulation.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4751A specification in the DO-41 package. Verify that alternative parts match the 30 V Zener voltage, 1 W power rating, and 5% tolerance to ensure functional compatibility.
