Overview
The onsemi 1N4743CRL is a single-channel general-purpose Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range from -65°C to +200°C. Key electrical parameters include a test current of 19 mA, a maximum Zener impedance of 10 Ω, and a maximum reverse leakage current of 5 μA. It utilizes a DO-41 through-hole package.
Feature Summary
- Provides stable voltage regulation using a single-channel silicon junction design.
- Features hermetically sealed glass construction for high reliability in harsh environments.
- Supports extended thermal operation up to 200°C for demanding industrial conditions.
Applications
- Voltage reference circuits
- Overvoltage protection systems
- General-purpose voltage regulation
Procurement Notes
Verify the specific suffix 'CRL' against official manufacturer documentation to confirm exact manufacturing origin and compliance status. Ensure the component matches the required DO-41 package dimensions and lead finish specifications for your assembly process. Cross-reference the datasheet revision date to validate all electrical limits before integration.
Selection Notes
Select this component when a 13 V regulation point is required with ±5% precision. The 1 W power rating suits moderate current applications. Verify that the operating environment stays within the specified -65°C to +200°C range. Confirm that the DO-41 through-hole form factor fits the target PCB layout constraints.
Part Context
This part belongs to the 1N47 series of 1-watt Zener diodes manufactured by onsemi. These devices are standard components used for basic voltage clamping and reference tasks. The series offers a wide range of voltage options within the same physical package, allowing for flexible design choices across various electronic equipment categories.
Replacement Considerations
Compatible substitutes include the MX1N4743DURE3TR (Microsemi) and 1N4743AHA0G (Taiwan Semiconductor). Verify that replacement parts maintain the 13 V nominal voltage, 1 W power rating, and DO-41 or equivalent package compatibility.
