1N4745G R0G

Overview

The 1N4745G R0G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 16V with a tolerance of ±5%. The device is designed for a maximum steady-state power dissipation of 1W at an ambient temperature of 25°C. It utilizes a DO-41 axial leaded package and employs hermetically sealed glass construction. The component operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Hermetically sealed glass construction for environmental resistance
• Compression bonded internal design
• Through-hole mounting configuration
• Corrosion-resistant external surfaces

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection applications
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'R0G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications. Ensure compliance requirements match project standards, as standard variants may differ in RoHS status or marking codes. Confirm availability directly with the manufacturer or authorized distributors.

Selection Notes

Select this component when a 16V Zener voltage with ±5% tolerance is required in a through-hole package. The 1W power rating suits moderate current applications. Verify thermal derating requirements if operating above 50°C. Compare dynamic impedance specifications against circuit sensitivity needs.

Part Context

This part belongs to the 1N47xx series of 1W Zener diodes offered by Taiwan Semiconductor. The series provides a wide voltage range from 3.3V to 56V. The 'G' suffix typically denotes a ±5% tolerance variant, distinguishing it from tighter tolerance options like the 'C' suffix.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4745A equivalents in DO-41 packages. Verify pinout compatibility and thermal characteristics before substitution.
