1N4739CE3/TR13

Overview

The Microchip Technology 1N4739CE3/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 9.1 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 on its terminals.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance for stable reference applications
• Utilizes void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Features flexible axial-lead mounting terminals suitable for standard PCB assembly
• Operates reliably across a broad temperature range from -65°C to +150°C

Applications

• Voltage regulation circuits requiring high precision
• Reference voltage sources in electronic systems
• Overvoltage protection components

Procurement Notes

Verify that the specific part number includes the required suffixes for your application needs. Confirm RoHS compliance status and packaging details such as tape and reel specifications directly with the manufacturer or authorized distributors before ordering. Ensure compatibility with existing thermal management designs given the power dissipation ratings.

Selection Notes

Select this component when a 9.1 V Zener voltage with ±2% tolerance is required in an axial-lead package. Consider the 1.0 W power dissipation capability and operating temperature range for your specific circuit environment. Verify if tighter tolerances or different voltages are needed for alternative selections within the same series.

Part Context

This component belongs to the popular 1N4728AP through 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers extensive voltage selection from 3.3 to 100 volts. The 'e3' suffix denotes RoHS compliance, while 'TR13' indicates tape and reel packaging options available for automated assembly processes.

Replacement Considerations

Compatible replacements include other 1N4739 variants with matching electrical characteristics and package types. Ensure any substitute maintains the 9.1 V Zener voltage, ±2% tolerance, and 1.0 W power rating. Verify terminal plating and moisture sensitivity levels match original design requirements.
