1N4738G R0G

Overview

The 1N4738G R0G is a small signal Zener diode manufactured by Taiwan Semiconductor Corporation. It features an 8.2 V nominal Zener voltage with a ±5% tolerance and a maximum power dissipation of 1 W (1000 mW). The component utilizes silicon technology and is housed in the DO-204AL (DO-41) axial leaded package. This device is designed for voltage regulation and reference applications within electronic circuits.

Feature Summary

• Provides stable voltage regulation at 8.2 V
• Handles up to 1 W of power dissipation
• Constructed with silicon semiconductor material

Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix 'R0G' to confirm tape and reel packaging configuration, as standard equivalents may differ in shipping format. Confirm current product status, as some listings indicate this specific variant may be obsolete or discontinued. Ensure compatibility with DO-204AL footprint requirements during integration planning.

Selection Notes

Select this component when an 8.2 V Zener reference with 1 W power rating is required in an axial package. The ±5% tolerance suits general regulation tasks. Compare against Microsemi MV1N4738 variants if different tolerance levels or manufacturer sourcing are necessary for the design.

Part Context

This part belongs to the 1N4738 series of Zener diodes, a standard industry designation for 8.2 V devices. The 'G' typically denotes RoHS compliance, while 'R0G' specifies the reel packaging format from Taiwan Semiconductor. It serves as a direct functional equivalent to generic 1N4738 parts across various manufacturers.

Replacement Considerations

Public confirmed substitutes include onsemi 1N4738ATR and Microsemi MV1N4738APTR (±5%) or MV1N4738DPTR (±1%). Verify pinout compatibility with DO-204AL packages before substitution.
