Overview
The Microchip Technology 1N4733A/TR is a single voltage regulator Zener diode designed for surface mount applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device operates within a power dissipation rating of 1 W and is housed in the DO-213AB-2 package. Key electrical characteristics include a maximum reverse leakage current of 5 uA, a Zener impedance of 7 Ohms, and a test current of 49 mA. It supports a forward current of 200 mA and functions across an extended temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation at a nominal 5.1 V level with tight manufacturing tolerances.
- Engineered for high-temperature reliability with an operational range extending up to 175 C.
- Optimized for surface mount technology integration using the compact DO-213AB-2 form factor.
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in sensitive electronic systems
- Clamping applications for transient suppression
Procurement Notes
Verify the specific manufacturer part number against official Microchip Technology documentation to ensure authenticity. Confirm that the DO-213AB-2 package dimensions align with your printed circuit board layout requirements. Check the latest datasheet for any revisions regarding testing conditions or absolute maximum ratings before finalizing procurement specifications.
Selection Notes
Select this component when a surface mount solution is required for 5.1 V regulation tasks. Ensure the design accommodates the 1 W power dissipation capability under expected operating conditions. Verify that the 7 Ohm impedance meets the dynamic performance needs of the target application circuit.
Part Context
This component belongs to the standard Zener diode category produced by Microchip Technology. It utilizes silicon planar technology for consistent performance. The device is distinct from through-hole variants due to its specific surface mount packaging and associated thermal characteristics.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 5.1 V Zener diodes in the DO-213AB-2 package. Verify that substitute parts match the 5% voltage tolerance and 1 W power rating to maintain circuit integrity.
