1N4734APE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N4734APE3/TR8 is a silicon 1.0-watt Zener diode in the JEDEC registered 1N4728AP through 1N4764AP series. 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 a plastic DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 5 Ohms at a test current of 45 mA, a maximum reverse current of 10 µA, and a maximum forward voltage of 1.2 V at 200 mA.

Single Zener Diodes 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
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and annealed matte-Tin plating as specified in the datasheet. Confirm the 'TR' suffix indicates tape and reel packaging per EIA-296 standards. Ensure the component matches the specific 1N4734A designation within the 1N4728AP through 1N4764AP series for correct electrical parameters.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 5.6 V reference with ±5% tolerance. Consider the 1.0 W power dissipation rating and thermal resistance values when designing heat management. Verify compatibility with the DO-41 package dimensions and lead spacing for PCB layout requirements.

Single Zener Diodes Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers extensive voltage selection from 3.3 to 100 volts. The 'e3' suffix denotes RoHS compliant devices available from Microsemi.

Single Zener Diodes Replacement Considerations
