Overview
The Microsemi Corporation 1N4761APE3/TR12 is a silicon 1.0-watt Zener diode 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 5%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating on its terminals.
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
- Moisture classified as Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm material composition, tolerance class, and packaging format. Ensure that the RoHS compliant 'e3' designation matches project requirements for terminal plating specifications. Confirm tape and reel availability if automated assembly processes are utilized.
Selection Notes
Select this component when a 75 V regulation point is required in a high-power dissipation environment. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the 5% tolerance meets circuit precision requirements before finalizing the design.
Part Context
This part belongs to the 1N4728AP through 1N4764AP series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix indicates plastic encapsulation, while the 'e3' suffix denotes RoHS compliance.
Replacement Considerations
Surface mount equivalents are available as SMAJ4761A and MLL4761A. Other manufacturers may offer direct replacements within the JEDEC registered 1N4761A specification family.
