1N4761PE3/TR12

Overview

The Microsemi Corporation 1N4761PE3/TR12 is a silicon 1.0-watt Zener diode in the JEDEC registered 1N4728A to 1N4764A series, housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation at a nominal Zener voltage of 75 V with a standard tolerance of plus or minus 10%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance indicated by the 'e3' suffix. Packaged in tape and reel format per EIA-296 standards, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 75 V reference
• Power supply protection against overvoltage conditions
• General purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific ordering suffixes required for your application, as prefixes like MQ, MX, MV, or MSP indicate different military screening levels under MIL-PRF-19500. Confirm that the tape and reel packaging meets your automated assembly requirements. Ensure compatibility with the specified thermal resistance values when designing heat dissipation strategies for the final product.

Selection Notes

Select this component when a 75 V Zener voltage with 10% tolerance is required in a plastic axial package. Consider the lower thermal resistance of the plastic body compared to glass-body options if thermal management is a priority. Verify that the maximum power dissipation of 1.0 watt aligns with your circuit's steady-state and surge current requirements.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 100 volts. The 'P' suffix designates the plastic encapsulated version, which offers lower thermal resistance than the glass-body alternative. The 'TR' suffix indicates the tape and reel packaging option.

Replacement Considerations

Surface mount equivalents are available as SMAJ4761A and MLL4761A. For higher reliability requirements, consider variants with military screening prefixes such as MQ1N4761DP or MSP1N4761DPTR.
