Overview
The onsemi 1N4733A-T50R is a single Zener diode with a nominal voltage of 5.1 V and a power dissipation rating of 1 W. It features a 5% voltage tolerance and operates within a temperature range of -65°C to +200°C. The device utilizes a DO-41-2 through-hole package, measuring 5.2 mm in length and 2.72 mm in diameter. Key electrical parameters include a maximum reverse leakage current of 10 µA and a Zener impedance of 7 Ohms at a test current of 49 mA.
Feature Summary
- Provides stable voltage regulation via Zener breakdown characteristics
- Designed for through-hole mounting in standard axial configurations
- Capable of operation across an extended industrial temperature range
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- Clamping applications for signal or power lines
Procurement Notes
Verify the specific suffix T50R against your bill of materials, as it denotes tape and reel packaging which differs from bulk options. Confirm that the 1 W power rating and 5.1 V specification align with your thermal and circuit design requirements. Ensure compatibility with existing assembly processes for DO-41 components.
Selection Notes
Select this component when a 5.1 V regulated node is required in a through-hole design. The 1 W dissipation capability supports moderate current loads. Consider the 7 Ohm impedance for dynamic load performance. Verify that the 200°C maximum junction temperature meets the environmental constraints of the target application.
Part Context
This part belongs to the 1N4733A series of Zener diodes manufactured by onsemi. The T50R suffix indicates a specific tape and reel packaging format intended for automated surface mount or through-hole insertion equipment, distinguishing it from bulk or other reel variants like the 1N4733A-TR.
Replacement Considerations
Direct substitutes include the 1N4733A and 1N4733A-133 from Nexperia. Verify pinout compatibility and ensure equivalent electrical ratings before substitution.
