Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as the 1N5241B part number is widely produced by multiple semiconductor vendors including Vishay, Rectron, and NXP. Confirm that the T50R suffix corresponds to the required tape-and-reel packaging format from onsemi. Ensure the procurement specification explicitly requires the 500 mW power rating and DO-35 package style to match the intended design constraints.

Single Zener Diodes Selection Notes

Select this component for applications requiring an 11 V reference point with moderate precision. The 5% tolerance suits standard regulation tasks where tight accuracy is not critical. Consider the 500 mW power rating for thermal management in compact designs. The wide operating temperature range makes it suitable for industrial environments. Verify compatibility with the target PCB footprint for the DO-35 axial leaded package.

Single Zener Diodes Part Context

This component belongs to the 1N52xx series of Zener diodes, a standard family used for voltage regulation and clipping. The 1N5241B variant specifically targets the 11 V breakdown region. The T50R suffix typically indicates a specific reel quantity or packaging configuration provided by the manufacturer. This series is characterized by its robust glass encapsulation and reliable performance in general electronic circuits.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5241B from other manufacturers such as Vishay Semiconductors, Rectron Semiconductor, and NXP. When replacing, ensure the alternative part matches the 11 V nominal voltage, 500 mW power dissipation, and DO-35 package dimensions. Verify that the replacement's Zener impedance and leakage current specifications meet the original circuit requirements.
