1N4741CE3/TR13

Overview

The Microchip Technology 1N4741CE3/TR13 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation at a nominal Zener voltage of 11 volts with a tight tolerance of plus or minus 2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring precise reference voltages
• Power supply protection and clamping applications
• Temperature compensated reference designs

Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm compliance requirements and packaging options. Ensure that the 'TR' suffix corresponds to tape and reel delivery as specified in the datasheet. Confirm RoHS status and terminal plating details directly from the manufacturer's latest product change notifications before procurement.

Selection Notes

Select this component when a 1-watt power dissipation rating and an 11-volt regulation point are required. The 'C' suffix indicates a tighter 2% voltage tolerance compared to standard 5% or 10% variants. Consider the plastic DO-41 package for lower thermal resistance relative to glass-body options, suitable for general-purpose industrial and commercial environments.

Part Context

This part belongs to the widely used 1N47xx series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a voltage range from 3.3 to 100 volts. The 'e3' suffix denotes RoHS compliance, while 'P' indicates the plastic encapsulated version which offers improved thermal characteristics over traditional glass packages.

Replacement Considerations

Compatible replacements include other 1N4741A variants from different manufacturers provided they meet the 1-watt power rating and 11-volt specification. Surface mount equivalents such as SMAJ4741A may be considered if board space permits, though mechanical mounting differences must be addressed.
