1N4741A-T

Overview

The 1N4741A-T is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 11V with a tolerance of 5%. The device is rated for a power dissipation of 1W and operates within a temperature range from -65°C to +175°C. It utilizes the DO-41 axial leaded package, featuring a molded plastic case with UL94V-0 flame retardant epoxy. The component is designed for unidirectional voltage regulation applications.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features a rugged DO-41 axial leaded package for through-hole mounting
• Constructed with UL94V-0 flame retardant epoxy for safety compliance

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipper and clamper circuits

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N4741A part number is produced by multiple vendors including EIC and Pingwei. Confirm that the '-T' suffix corresponds to the standard tape-and-reel or bulk packaging format intended for your assembly process. Ensure the selected unit meets the required RoHS compliance standards if applicable to your manufacturing environment.

Selection Notes

Select this component for general-purpose voltage regulation where a 11V reference is required. The 1W power rating allows for moderate current handling in series resistor configurations. Consider the DO-41 package dimensions for PCB layout constraints. Verify thermal management requirements based on the maximum operating temperature of 175°C and expected ambient conditions.

Part Context

This component belongs to the standard 1N47xx series of Zener diodes, widely used in electronic design for basic voltage stabilization. The 1N4741A variant specifically targets the 11V market segment within the 1W power class. It serves as a fundamental discrete semiconductor element for linear regulator stages and protection networks in consumer and industrial electronics.

Replacement Considerations

Equivalent parts include the 1N4741A from other manufacturers such as EIC or Pingwei, provided they meet the same 11V, 1W, and DO-41 specifications. Cross-reference datasheets to ensure identical electrical characteristics and mechanical dimensions before substitution.
