1N4736E3/TR13

Overview

The Microchip Technology 1N4736E3/TR13 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) package. It provides voltage regulation with a nominal Zener voltage of 6.8 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C. Key electrical characteristics include a test current of 37 mA, a maximum dynamic impedance of 3.5 Ohms at the test current, and a maximum reverse current of 10 µA. The component is RoHS compliant and available in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard installation
• 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 6.8 V reference
• Power supply protection and clamping applications
• General purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and compliance status. Confirm that the TR13 designation aligns with the required tape and reel specifications for automated assembly processes. Ensure compatibility with existing thermal management designs given the 1.0-watt power dissipation rating.

Selection Notes

Select this component when a 6.8 V Zener voltage with ±5% tolerance is required in a plastic axial package. Consider the 1.0-watt power dissipation capability and the -65°C to +150°C operating temperature range for environmental suitability. Verify that the 3.5 Ohm dynamic impedance meets the circuit's stability requirements.

Part Context

This part belongs to the JEDEC registered 1N4728A through 1N4764A series of silicon Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging options provided by Microsemi.

Replacement Considerations

Cross-reference with other 1N4736 variants such as 1N4736A or 1N4736G if glass-body or different tolerance options are acceptable. Verify pinout and thermal resistance differences when substituting between plastic and glass encapsulated versions.
