1N4734G R0G

Overview

The 1N4734G R0G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device has a power dissipation rating of 1 W and operates within a temperature range of -65°C to +200°C. It utilizes a DO-41 through-hole package with a glass compression bonded construction. Key electrical characteristics include a maximum reverse leakage current of 5 uA, a Zener impedance of 5 Ohms, and a test current of 45 mA.

Feature Summary

• Hermetically sealed glass compression bonded construction for environmental resistance
• High temperature soldering capability guaranteed at 260°C for 10 seconds
• Corrosion resistant external surfaces with readily solderable pure tin plated leads

Applications

• Stabilizing circuits requiring high power ratings
• Clipping circuits in electronic designs
• Voltage regulation applications utilizing the DO-41 through-hole form factor

Procurement Notes

Verify the specific suffix 'R0G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications and RoHS compliance status. Ensure the ordering part number matches the exact mechanical dimensions and marking codes defined in the manufacturer's datasheet for the 1N4728G to 1N4758G series.

Selection Notes

Select this component for applications requiring a 5.6 V reference with ±5% accuracy and 1 W power handling. The DO-41 package suits through-hole mounting requirements. Consider the extended operating temperature range up to +200°C for high-thermal environments. Verify lead finish compatibility if strict lead-free standards apply beyond standard RoHS.

Part Context

This component belongs to the 1N47xxG series of 1 Watt Zener diodes produced by Taiwan Semiconductor. The series covers a wide voltage range from 3.3 V to 56 V. These devices are designed for general-purpose voltage regulation and protection, offering robust performance in axial-leaded packages suitable for industrial and commercial electronics.

Replacement Considerations

Equivalent parts include the 1N4734A from Microchip Technology and the 1N4734 from Nexperia. Ensure replacement components match the 1 W power rating, 5.6 V Zener voltage, and DO-41 package dimensions.
