Overview
The Microchip Technology 1N4752AE3 is a silicon unidirectional Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 33V with a standard tolerance of 5%. The device is rated for a maximum power dissipation of 1W and utilizes the DO-41 axial leaded package. It is RoHS compliant and hermetically sealed within a glass body, ensuring high reliability in demanding environments.
Feature Summary
- Hermetically sealed glass encapsulation for enhanced environmental protection
- High-reliability construction suitable for critical circuit applications
- Surface mountable equivalent available in DO-213AB package
Applications
- Voltage regulation in high-density circuits
- Protection against voltage transients
- Reference voltage generation in precision instrumentation
Procurement Notes
Verify that the ordering suffix 'e3' confirms RoHS compliance and lead-free terminations. Confirm the package type matches the design requirements, as surface mount equivalents exist. Ensure the specific manufacturer source aligns with quality standards required by the application's source control drawing.
Selection Notes
Select this component when a 33V regulation point is required with 1W power handling capability. Consider the DO-41 package for through-hole mounting or the DO-213AB variant for surface mount needs. Verify that the 5% voltage tolerance meets the circuit's precision requirements.
Part Context
This part belongs to the widely recognized 1N47xx series of Zener diodes. It serves as the axial leaded version of the 1N4752A family, providing a robust solution for general-purpose voltage regulation where hermetic sealing and high reliability are prioritized over compact surface mount footprints.
Replacement Considerations
The 1N4752AG offers similar electrical characteristics with a G suffix indicating hermetic sealing. Surface mount designs may utilize the 1N4752AUR or 1N4752AURE3 variants which share identical electrical performance but differ in physical package form factor.
