Overview
The onsemi 1N4744A-T50R is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and operates within a temperature range from -65 °C to +200 °C. It utilizes the DO-41-2 through-hole package, measuring 5.2 mm in length and 2.72 mm in diameter. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 14 Ohms at a test current of 17 mA.
Feature Summary
- Provides stable voltage regulation with a nominal 15 V output.
- Capable of handling 1 W power dissipation in a compact axial leaded package.
- Operates reliably across an extended temperature range up to 200 °C.
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status as required by project specifications. Ensure the DO-41-2 package dimensions match PCB footprint requirements. Validate that the 15 V Zener voltage meets circuit design tolerances before integration.
Selection Notes
Select this component when a 15 V regulated supply is needed in a through-hole configuration. Consider the 1 W power rating for thermal management in the design. The wide operating temperature range suits harsh environments. Verify compatibility with existing assembly processes for axial leaded components.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes, widely used for general-purpose voltage regulation. The 'T50R' suffix typically indicates specific tape-and-reel packaging for automated assembly. The 1N4744A designation specifically identifies the 15 V variant within this family.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4744A equivalents in DO-41 packages. Verify pinout compatibility and ensure replacement parts meet the same 1 W power and 15 V voltage specifications. Check for any differences in Zener impedance or leakage current that might affect circuit performance.
