1N4732G R0G

Overview

The 1N4732G R0G is a silicon planar power Zener diode manufactured by Taiwan Semiconductor. It features a DO-41 glass axial-leaded package designed for through-hole mounting. The device provides a nominal Zener voltage of 4.7V with a standard tolerance of ±10%. It is rated for a maximum power dissipation of 1W at 25°C ambient temperature. The component utilizes a hermetically sealed glass case to ensure corrosion resistance and reliable performance in stabilizing and clipping circuits.

Feature Summary

• Hermetically sealed glass construction for enhanced environmental protection
• High temperature soldering capability up to 260°C for 10 seconds
• Corrosion-resistant external surfaces with readily solderable tin terminals

Applications

• Voltage regulation in power supply circuits
• Signal clipping and wave shaping
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to confirm tolerance and packaging details. Ensure compliance requirements match project specifications, as historical data indicates variations in RoHS status across different production batches and suffixes. Cross-reference the part number with official Taiwan Semiconductor documentation to validate availability and exact electrical characteristics before procurement.

Selection Notes

Select this component for applications requiring a 4.7V reference or regulation point with 1W power handling capabilities. The DO-41 package is suitable for general-purpose through-hole designs where space constraints are not critical. Consider the ±10% tolerance for standard regulation tasks; tighter tolerances may require alternative suffixes or precision variants if strict voltage accuracy is mandated by the circuit design.

Part Context

This part belongs to the 1N47xx series of power Zener diodes, a widely used family for voltage regulation. The 'G' suffix typically denotes a specific tolerance or packaging variant within the manufacturer's lineup. The 1N4732 designation specifically identifies the 4.7V breakdown voltage characteristic common across multiple manufacturers producing this standardized JEDEC-style component.

Replacement Considerations

Direct substitutes include parts from other manufacturers offering the same 1N4732 specification, such as Microchip's 1N4732A or Taitron's 1N4732A. Verify that replacement components maintain the DO-41 package dimensions and 1W power rating to ensure mechanical and thermal compatibility.
