1N4753P/TR8

Overview

The Microchip Technology 1N4753P/TR8 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a DO-41 (DO-204AL) plastic axial-lead package. It provides voltage regulation with a nominal Zener voltage of 36 V and a standard tolerance of ±10%. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 50 ohms at a test current of 7.0 mA. It includes a tape and reel option for automated assembly.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• 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 in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in analog signal processing

Procurement Notes

Verify that the ordering suffix TR8 corresponds to the specified tape and reel packaging configuration as defined by EIA-296 standards. Confirm the component matches the JEDEC registered 1N4753A type number specifications. Ensure the manufacturer source aligns with Microchip Technology or authorized Microsemi distribution channels to guarantee authenticity and compliance with the documented electrical characteristics.

Selection Notes

Select this component when a 36 V regulation point is required in a through-hole design. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Consider the ±10% tolerance if tighter precision is not critical. Verify that the 1 W power dissipation rating meets the circuit's thermal requirements under steady-state conditions.

Part Context

This part belongs to the widely used 1N47xx series of 1-watt Zener diodes. The 'P' suffix indicates plastic construction, while 'TR8' denotes the specific tape and reel packaging format. The series covers an extensive voltage selection from 3.3 V to 100 V, allowing for standardized design approaches across various industrial and commercial electronics applications.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4753A devices in DO-41 packages. Surface mount equivalents are available as SMAJ4753A or MLL4753A. Verify pinout compatibility and ensure the replacement meets the same 1 W power dissipation and 36 V Zener voltage specifications.
