1N4734CE3/TR13

Overview

The Microchip Technology 1N4734CE3/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 with a nominal Zener voltage of 5.6 V and a tight tolerance of ±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, denoted by the 'e3' suffix. Packaged in tape and reel format per EIA-296 standards, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

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

Applications

• Voltage regulation circuits requiring precise 5.6 V reference levels
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the specific part number includes both the 'C' suffix for 2% tolerance and the 'e3' suffix for RoHS compliance. Confirm the 'TR' designation indicates tape and reel packaging rather than bulk or cut tape. Ensure the component matches the Microsemi/Microchip 1N4728AP-1N4764AP series specifications for power dissipation and thermal resistance requirements.

Selection Notes

Select this component when a 5.6 V Zener voltage with tighter than standard 5% tolerance is required. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the ±2% tolerance if circuit precision demands stricter voltage limits than the standard 'A' suffix devices provide.

Part Context

This device belongs to the widely used 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 'C' suffix identifies the 2% tolerance variant, while the 'e3' suffix confirms RoHS compliance. The 'TR' suffix specifies the tape and reel packaging option available for automated assembly processes.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4734A equivalents with matching 5.6 V and 1 W ratings. For tighter tolerances, verify availability of 1N4734D variants. Surface mount replacements such as SMAJ4734A or MLL4734A are available but require different footprint considerations.
