Overview
The Microchip Technology 1N4733AURE3 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The component operates in the DO-213AB-2 surface-mount package and supports a power dissipation of 1 W. Key electrical parameters include a maximum reverse leakage current of 5 uA, a Zener impedance of 7 Ohms, and a test current of 49 mA. It functions within an operating temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation using unidirectional silicon Zener technology
- Features hermetic sealing for high reliability in harsh environments
- Supports surface-mount installation via the DO-213AB-2 package
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in sensitive electronic systems
- Clamping applications for transient voltage suppression
Procurement Notes
Verify the specific suffix configuration against project requirements to ensure compatibility with environmental standards and packaging preferences. Confirm that the selected variant matches the required thermal management capabilities and lead-free compliance specifications before finalizing procurement orders.
Selection Notes
Select this component when a robust, hermetically sealed Zener diode is needed for surface-mount designs. Ensure the circuit design accommodates the specified 1 W power dissipation and 5.1 V nominal voltage. Verify that the operating environment remains within the defined temperature limits for optimal performance.
Part Context
This device belongs to the standard 1N4733A series of power Zener diodes manufactured by Microchip Technology. It represents a transition from traditional axial-lead packages to modern surface-mount formats while maintaining the electrical characteristics associated with the legacy part number designation.
Replacement Considerations
Direct substitutes include the 1N4733AUR/TR reel variant from Microchip Technology. Other manufacturers may offer equivalent specifications under different part numbers, but verification of package dimensions and electrical tolerances is required.
