1N4761AP/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N4761AP/TR12 is a silicon Zener diode with a nominal voltage of 75V and a 5% tolerance. It operates in a DO-41 plastic package, dissipating up to 1W at 25°C. The device features a maximum dynamic impedance of 175 ohms at a test current of 3.3mA and a reverse current of 5µA at 56V. It withstands surge currents up to 60mA and functions within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

• Voltage regulation circuits requiring 75V reference
• Power supply protection against overvoltage conditions
• General-purpose clamping applications in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm RoHS compliance status and screening levels. Confirm that the TR12 designation aligns with the manufacturer's tape and reel specifications. Ensure the component meets all environmental and electrical requirements for the intended application before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 75V Zener voltage with 5% tolerance is required in an axial-lead package. Consider the 1W power dissipation capability and thermal resistance characteristics for heat management. Evaluate the operating temperature range and surge current ratings to ensure compatibility with system stress conditions.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N4728A through 1N4764A series of 1-watt Zener diodes. The 'P' suffix indicates plastic encapsulation, offering lower thermal resistance compared to glass-body options. The 'TR' suffix denotes availability in tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N4761A variants in DO-41 packages. Surface mount equivalents are available as SMAJ4761A or MLL4761A. Verify pinout compatibility and electrical parameters when substituting.
