1N4734G

Overview

The Taiwan Semiconductor Corporation 1N4734G is a silicon Zener diode with a nominal voltage of 5.6V and a tolerance of ±5%. It operates in the DO-41 axial lead package, providing a steady-state power dissipation of 1W at 25°C ambient temperature. The device features hermetically sealed glass construction and pure tin-plated leads. Electrical characteristics include a maximum dynamic impedance of 5Ω at a test current of 45mA and a leakage current of 10µA at 2V reverse voltage. Thermal resistance values are 53.5°C/W junction-to-lead and 100°C/W junction-to-ambient.

Feature Summary

• Hermetically sealed glass compression bonded construction for corrosion resistance
• Pure tin plated leads ensuring solderability per J-STD-002 standards
• Wide Zener voltage range selection from 3.3V to 56V within the series

Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converter

Procurement Notes

Verify that the specific part number matches the required voltage and tolerance specifications. Confirm compliance with RoHS directives as indicated by the datasheet version. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Check for any specific packaging requirements such as reel or ammo box quantities if applicable to the production line.

Selection Notes

Select this component when a 5.6V reference with ±5% accuracy is required in an axial lead package. Consider the 1W power dissipation limit and thermal resistance values for heat management. Verify that the operating temperature range of -65°C to +200°C meets the environmental conditions of the target application.

Part Context

This component belongs to the 1N4728G through 1N4758G series manufactured by Taiwan Semiconductor. The series covers a broad spectrum of Zener voltages from 3.3V to 56V. All devices in this family share the same DO-41 package and hermetically sealed glass construction, offering consistent mechanical and electrical performance across different voltage ratings.

Replacement Considerations

Equivalent parts must match the 5.6V Zener voltage, 1W power rating, and DO-41 package. Verify that replacement components also offer hermetically sealed glass construction and similar thermal characteristics to ensure reliable operation in existing designs.
