1N4752E3/TR13

Overview

The Microchip Technology 1N4752E3/TR13 is a silicon 1-watt Zener diode with a nominal voltage of 33V and a standard tolerance of ±5%. It utilizes a plastic encapsulated DO-41 axial lead package. The device operates within a temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile circuit integration
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0 standards

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Overvoltage protection applications

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm material composition and screening levels. Ensure compatibility with required thermal management strategies given the 1.0-watt dissipation rating. Confirm that the tape and reel packaging aligns with automated assembly equipment specifications.

Selection Notes

Select this component for applications requiring precise 33V regulation with standard tolerance. Consider the plastic body construction for lower thermal resistance compared to glass options. Evaluate the axial lead format for through-hole mounting requirements where surface mount alternatives are unsuitable.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers an extensive voltage selection from 3.3 to 100 volts. The 'e3' suffix indicates RoHS compliance, while the 'TR13' designation specifies tape and reel packaging per EIA-296 standards.

Replacement Considerations

Surface mount equivalents such as SMAJ4752A or MLL4752A are available. Glass-body options designated with a 'G' suffix exist but exhibit higher thermal resistance.
