1N4731G R0G

Single Zener Diodes Overview

The 1N4731G R0G is a Zener diode manufactured by Taiwan Semiconductor Corporation. It belongs to the 1N4728G through 1N4758G series of small signal products, featuring a 1W power dissipation rating and housed in a DO-41 package. The device utilizes a hermetically sealed glass body with corrosion-resistant external surfaces and solderable tin terminals. It provides voltage regulation within a range of 3.3 to 56 volts, offering standard ±5% tolerance for the 'G' suffix variant. The component supports through-hole mounting and guarantees high-temperature soldering capability at 260°C for 10 seconds.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction ensuring environmental resistance
• Through-hole mounting design compatible with standard DO-41 footprints
• Corrosion-resistant external surfaces with readily solderable tin terminals

Single Zener Diodes Applications

• Voltage regulation circuits requiring 1W power handling
• Clipping and stabilizing applications in electronic systems
• General-purpose discrete semiconductor protection

Single Zener Diodes Procurement Notes

Verify RoHS compliance status as datasheets indicate e3 marking availability but general listings may vary. Confirm specific tolerance requirements, noting that 'G' denotes ±5% while 'C' indicates tighter tolerances. Ensure procurement channels provide official manufacturer documentation to validate hermetic sealing claims and thermal ratings against current production standards.

Single Zener Diodes Selection Notes

Select this component when a robust, hermetically sealed axial leaded Zener diode is required for high-reliability environments. The DO-41 glass package offers superior thermal stability compared to plastic alternatives. Consider the ±5% voltage tolerance suitable for general regulation tasks where extreme precision is not critical, and verify compatibility with high-temperature soldering processes up to 260°C.

Single Zener Diodes Part Context

This part is part of the widely recognized 1N47xx series of 1-watt Zener diodes. The 'G' suffix specifically identifies the ±5% tolerance version within Taiwan Semiconductor's lineup. It serves as a direct replacement for legacy MIL-spec components in modern designs, bridging traditional military-grade reliability with contemporary surface-mount and through-hole manufacturing needs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4731A or 1N4731 variants in DO-41 packages. Verify that replacements maintain the same 1W power dissipation and hermetic sealing if environmental resistance is required. Cross-reference terminal plating specifications to ensure solderability matches the original tin finish.
