1N4734APE3/TR12

Overview

The Microchip Technology 1N4734APE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP to 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 5.6V 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.

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
• Classified as Level 1 moisture sensitivity requiring no dry pack

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify that the specific ordering suffix matches the required package type and compliance status. Confirm the manufacturer origin, as this part number lineage originates from Microsemi Scottsdale Division data now managed by Microchip Technology. Ensure the reel quantity aligns with production requirements before finalizing procurement orders.

Selection Notes

Select this component when a 5.6V regulated reference is needed in a robust plastic axial package. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the ±5% voltage tolerance meets circuit precision requirements and that the 1.0W power dissipation rating suits the thermal environment.

Part Context

This device belongs to the JEDEC registered 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The 'P' suffix indicates plastic encapsulation, while the 'e3' suffix denotes RoHS compliance with tin-lead or matte-tin terminations. The 'TR' suffix specifies tape and reel packaging per EIA-296 standards.

Replacement Considerations

Direct replacements include other 1N4734 variants such as 1N4734A or 1N4734G, provided the package style and tolerance requirements are compatible.
