1N4734CP/TR8

Overview

The Microchip Technology 1N4734CP/TR8 is a silicon 1-watt Zener diode in the 1N4728AP to 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 5.6V 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 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 regulator current of 162 mA.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance on nominal Zener voltage.
• Features flexible axial-lead mounting terminals suitable for through-hole applications.
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability ratings.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B, requiring no dry pack.

Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose circuit protection
• Reference voltage sources

Procurement Notes

Verify that the specific part number matches the required electrical tolerances and packaging format. Confirm the manufacturer origin, as this component family is produced by Microsemi under the Microchip Technology portfolio. Ensure the ordering suffix aligns with the desired tape and reel configuration and compliance standards before finalizing procurement orders.

Selection Notes

Select this component when a 5.6V reference requires tighter than standard manufacturing tolerances. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the application environment remains within the specified operating temperature limits and that the power dissipation requirements do not exceed the rated capacity without appropriate derating.

Part Context

This component belongs to the popular 1N4728A through 1N4764A series of 1.0 watt Zener diodes. These devices are JEDEC registered and offer extensive voltage selection from 3.3 to 100 volts. The series includes various screening levels and package options to meet diverse electronic design requirements.

Replacement Considerations

Equivalent parts include 1N4734A, 1N4734AP, and 1N4734AG. Substitutes must match the 5.6V nominal voltage, 1W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
