1N4732G A0G

Overview

The 1N4732G A0G is a silicon unidirectional Zener voltage regulator diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 4.7V with a tolerance of ±5% and a maximum power dissipation of 1W at 25°C ambient temperature. The device utilizes the DO-41 glass axial leaded package, providing high stability and low inductance. Key electrical characteristics include a maximum reverse leakage current of 10µA and a dynamic impedance of 8Ω. It operates within a junction temperature range of -65°C to +200°C and supports soldering at 260°C for 10 seconds.

Feature Summary

• Hermetically sealed glass construction ensuring corrosion resistance
• High stability Zener voltage regulation from 3.3V to 56V series
• Low inductance design suitable for high-frequency applications
• RoHS compliant manufacturing process

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources
• Clamping applications

Procurement Notes

Verify the specific suffix 'A0G' against official Taiwan Semiconductor documentation to confirm exact packaging configuration and marking codes. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Request detailed datasheets for thermal derating curves and mechanical dimensions prior to integration.

Selection Notes

Select this component for applications requiring a stable 4.7V reference with 1W power handling capability. The DO-41 package is suitable for through-hole mounting on standard PCBs. Consider the 5% tolerance for precision requirements. Evaluate thermal management needs as power dissipation decreases with increasing ambient temperature above 25°C. Verify lead solderability per MIL-STD-208 if harsh environments are involved.

Part Context

This part belongs to the 1N47XXG series of 1W Zener diodes offered by Taiwan Semiconductor. The series provides a wide range of Zener voltages from 3.3V to 56V in the DO-41 package. These devices are designed for general-purpose voltage regulation and protection tasks. The 'G' suffix typically denotes RoHS compliance and specific manufacturing lot tracking within the company's product line.

Replacement Considerations

Compatible substitutes include the 1N4732A from other manufacturers such as Nexperia or onsemi, provided they meet the same 4.7V, 1W, and DO-41 specifications. Ensure that any replacement maintains the same Zener impedance and leakage current characteristics. Verify that the alternative part also offers hermetically sealed glass construction if environmental resistance is critical.
