1N4733G R0G

Overview

The 1N4733G R0G is a silicon planar power Zener diode manufactured by Taiwan Semiconductor Corporation. It provides a nominal voltage regulation of 5.1 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-41 axial leaded package. Key electrical characteristics include a maximum reverse leakage current of 10 µA, a Zener impedance of 7 Ω at the test current of 49 mA, and a forward voltage drop of 1.2 V at 200 mA. The component supports an operating junction temperature range from -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation using silicon planar technology
• Features hermetically sealed glass encapsulation for environmental protection
• Supports high thermal stability with extended operating temperature limits

Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific manufacturer datasheet for the 1N4733G R0G variant to confirm RoHS compliance status and exact packaging specifications. Ensure that the supplier documentation matches the required pinout and thermal ratings for your design. Cross-reference the suffix codes with official Taiwan Semiconductor literature to validate the reel quantity and handling instructions before finalizing procurement orders.

Selection Notes

Select this component when a 5.1 V regulation point is required with a 1 W power rating in an axial package. Consider the ±5% tolerance and 7 Ω impedance for precision requirements. Evaluate the thermal resistance and maximum junction temperature against the expected ambient conditions to ensure reliable operation within the specified -65 °C to +200 °C range without derating issues.

Part Context

This part belongs to the standard 1N47 series of one-watt Zener diodes. These components are widely used in general-purpose electronics for biasing and regulation. The 'G' suffix typically indicates Green/RoHS compliance, while 'R0G' specifies the tape and reel packaging format for automated assembly processes.

Replacement Considerations

Compatible substitutes include the 1N4733A from onsemi or Nexperia, which share identical electrical parameters and DO-41 packaging. Verify that any replacement maintains the same 5.1 V nominal voltage and 1 W power dissipation rating.
