1N4761PE3/TR8

Overview

The Microsemi Corporation 1N4761PE3/TR8 is a silicon Zener diode with a nominal voltage of 75 V and a maximum power dissipation of 1 W. It features a ±10% tolerance, a test current of 3.3 mA, and a maximum dynamic impedance of 175 Ohms at the test current. The device operates within a temperature range of -65°C to +150°C and utilizes a DO-204AL (DO-41) axial lead package. It is supplied in tape and reel packaging.

Feature Summary

• Provides voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• RoHS compliant devices are available with an e3 suffix indicating annealed matte-Tin plating

Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against overvoltage conditions in electronic systems
• Clamping applications for transient voltage suppression

Procurement Notes

Verify the specific ordering suffixes required for your application, as prefixes like MQ or MX indicate military screening levels per MIL-PRF-19500. Confirm that the RoHS compliant e3 suffix matches environmental requirements. Ensure the TR suffix is included if tape and reel packaging is necessary for automated assembly processes.

Selection Notes

Select this component when a 75 V Zener voltage with 1 W power handling is required in an axial lead package. Consider the plastic construction for lower thermal resistance compared to glass-body options. Evaluate the need for tighter tolerances by checking variants with C or D suffixes if standard 10% tolerance is insufficient for the design.

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 extensive voltage selection from 3.3 to 100 volts. These JEDEC registered devices are designed for general-purpose voltage regulation and are available in various screening levels and package options to meet diverse industrial and commercial needs.

Replacement Considerations

Surface mount equivalents are available as SMAJ4761A and MLL4761A. Glass-body versions exist under the same JEDEC numbering but require separate datasheet verification. Variants with different tolerance suffixes (C or D) offer tighter voltage accuracy.
