• Hermetically sealed glass compression bonded construction for excellent stability
• Glass passivated junction silicon technology
• Corrosion resistant external surfaces with readily solderable terminals

Applications

• General purpose industrial applications
• Entertainment equipment circuits
• Military and space applications

Procurement Notes

Verify the specific suffix 'R1G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications or tape-and-reel configuration details. Ensure the component matches the standard 1N4758A electrical characteristics, including the 56V Zener voltage and 1W power rating, as listed in the manufacturer's datasheet for the 1N4728A through 1N4762A series.

Selection Notes

Select this component for designs requiring a robust, high-reliability voltage reference or clipping circuit capable of handling 1W power dissipation. The DO-41 through-hole package facilitates easy integration into standard PCB layouts. Consider the 5% voltage tolerance and 110 ohm dynamic impedance when designing precision regulation stages.

Part Context

This part belongs to the 1N47xxA series of silicon planar power Zener diodes produced by Taiwan Semiconductor. These devices are designed for stabilizing and clipping circuits with high power ratings. The series covers a wide voltage range from 3.3V to 82V, utilizing a consistent DO-41 glass axial package format across all variants.

Replacement Considerations

Compatible substitutes include the 1N4758A from other manufacturers such as onsemi, Micro Commercial Components (MCC), and CDIL. Verify that replacement parts maintain the same DO-41 package, 56V Zener voltage, 5% tolerance, and 1W power dissipation capabilities.
