1N4734E3/TR13

Overview

The Microchip Technology 1N4734E3/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 standard tolerance of ±5%. 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 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 1.0-watt power dissipation
• General-purpose electronic designs utilizing standard JEDEC registered part numbers
• Applications necessitating moisture classification Level 1 without dry pack requirements

Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration, as the TR suffix indicates tape and reel supply. Confirm RoHS compliance status by checking the e3 designation against current manufacturing specifications. Ensure the procurement request aligns with the manufacturer's minimum order quantities and screening levels if military variants are not explicitly required.

Selection Notes

Select this component when a 5.6 V reference with ±5% tolerance is needed in an axial-lead package. Consider the plastic encapsulation for lower thermal resistance compared to glass-body options. Evaluate the maximum dynamic impedance and reverse current characteristics against circuit sensitivity requirements. Verify that the 1.0-watt power rating suits the thermal environment of the target application.

Part Context

This device belongs to the widely used 1N47xx series of Zener diodes, offering extensive voltage selection from 3.3 to 100 volts. The plastic encapsulated version provides a cost-effective alternative to glass-body devices while maintaining electrical equivalence to the original JEDEC registrations. The series supports various screening levels and surface mount equivalents for diverse design needs.

Replacement Considerations

Surface mount equivalents such as SMAJ4734A or MLL4734A are available for designs requiring different form factors. Glass-body versions like 1N4734G offer similar electrical performance but differ in thermal resistance and hermetic sealing properties.
