1N4741G

Overview

The Taiwan Semiconductor 1N4741G is a hermetically sealed glass passivated junction silicon Zener diode designed for voltage regulation and reference applications. It operates within the 1N4728G to 1N4758G series, offering a nominal Zener voltage of 11V with a standard tolerance of ±5%. The device features a DO-41 through-hole package and supports a maximum power dissipation of 1W at 25°C. It withstands junction temperatures ranging from -65°C to +200°C and includes pure tin-plated leads compliant with J-STD-002 solderability standards.

Feature Summary

• Hermetically sealed glass passivated junction construction
• Wide selection of Zener voltages from 3.3V to 56V
• Standard Zener voltage tolerance of ±5%
• Pure tin plated leads ensuring high solderability

Applications

• Low voltage stabilizers
• Voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix (e.g., R0G or A0G) against your packaging requirements, as these determine reel or ammo box quantities. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to procurement. Ensure the selected part number matches the required Zener voltage and tolerance specifications for your circuit design.

Selection Notes

Select the 1N4741G when an 11V Zener voltage with ±5% tolerance is required in a DO-41 package. Consider the 1W power dissipation limit and thermal resistance values for heat management in your application. Verify that the operating temperature range of -65°C to +200°C aligns with your environmental conditions. Compare leakage current and impedance parameters against other series members if tighter electrical characteristics are needed.

Part Context

The 1N4741G belongs to the 1N4728G–1N4758G series manufactured by Taiwan Semiconductor. This series covers a broad spectrum of Zener voltages from 3.3V up to 56V, all housed in the standardized DO-41 axial leaded package. The 'G' designation indicates the inclusion of green compound and hermetic sealing, distinguishing it from non-hermetic variants within the broader 1N47xxA family.

Replacement Considerations

Direct replacements include the 1N4741A and 1N4741B from various manufacturers, provided they meet the 11V, 1W, and DO-41 package requirements. Verify that substitute parts offer equivalent hermetic sealing and thermal performance if those factors are critical to your application.
