Overview
The Microsemi Corporation 1N4761A G is a silicon Zener diode designed for voltage regulation applications. It operates within the JEDEC registered 1N4728A to 1N4764A series, providing a nominal Zener voltage of 75 V with a standard tolerance of 5%. The component dissipates 1 W of power and utilizes a glass DO-41 axial lead package. Key electrical characteristics include a maximum reverse leakage current of 5 uA and a dynamic impedance of 175 Ohms at a test current of 3.3 mA. It supports an operating temperature range from -65 °C to +150 °C.
Feature Summary
- Provides stable voltage regulation across a broad operating current range
- Features low inductance construction suitable for high-speed switching
- Includes built-in strain relief for mechanical durability
- Offers high temperature soldering capability
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage sources
Procurement Notes
Verify the specific suffix 'G' against official datasheets to confirm glass encapsulation and RoHS status. Confirm availability as this part may require factory special orders. Ensure the selected variant meets the required military or commercial screening levels if applicable.
Selection Notes
Select this component when a 75 V reference is needed in a through-hole glass package. Consider the plastic equivalent (1N4761AP) if lower thermal resistance is required. Verify that the 5% tolerance aligns with circuit requirements before finalizing the design.
Part Context
This device belongs to the widely used 1N47xx series of 1-watt Zener diodes. The 'G' suffix typically denotes a glass body construction, distinguishing it from plastic molded variants. These components are standardized under JEDEC specifications, ensuring compatibility across various semiconductor manufacturers.
Replacement Considerations
Equivalent parts include 1N4761AP (plastic version) and generic 1N4761A from other manufacturers. Surface mount equivalents such as SMAJ4761A are available but require different mounting considerations.
