1N4736P/TR8

Overview

The Microchip Technology 1N4736P/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 axial lead package. It provides voltage regulation with a nominal Zener voltage of 6.8 V and a standard tolerance of ±10%. The device operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 10 µA at 4 V and a dynamic impedance of 3.5 Ω at a test current of 37 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• General voltage regulation circuits
• Voltage reference applications
• Over-voltage protection systems

Procurement Notes

Verify the specific manufacturer source, as the component originates from Microsemi which has been acquired by Microchip Technology. Confirm that the TR8 suffix corresponds to the tape and reel packaging format specified in the datasheet. Ensure the part meets required RoHS compliance standards if applicable to the design specifications.

Selection Notes

Select this component when a 6.8 V regulation point is required with a 1 W power dissipation capability. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the ±10% voltage tolerance aligns with circuit requirements, as tighter tolerances require different suffixes.

Part Context

This component belongs to the 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix indicates plastic encapsulation, while the 'TR' suffix denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

Equivalent parts include other 1N4736 variants such as 1N4736A or 1N4736Pe3. Substitutes must match the 6.8 V Zener voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
