1N5240B BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5240B BK TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in the DO-35 (DO-204AH) axial leaded glass package. It provides a nominal Zener voltage of 10 V with a tight tolerance of ±5%. The device dissipates up to 500 mW at standard ambient conditions and operates reliably within an extended temperature range from -65°C to +200°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 5 ohms, tested at a specific current of 25 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single P-N junction structure in a hermetically sealed glass envelope.
• Engineered for high thermal stability and reliable operation across extreme environmental temperatures.
• Features low Zener impedance to maintain consistent voltage performance under varying load conditions.

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the exact suffix 'BK TIN/LEAD' against the manufacturer's official documentation to confirm lead finish and packaging specifics. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the Mouser number 610-1N5240BBK-TL for accurate identification during ordering processes.

Single Zener Diodes Selection Notes

Select this component when a 10 V regulation point is required with strict tolerance limits. The DO-35 package suits designs needing axial leads for standard PCB drilling. Consider the 500 mW power rating and operating temperature range to ensure compatibility with the thermal environment of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xx series of 500 mW Zener diodes manufactured by Central Semiconductor. These components are standard industry choices for general-purpose voltage regulation. The specific B suffix indicates the tighter voltage tolerance compared to standard variants, ensuring higher precision for critical analog and digital logic supply lines.

Single Zener Diodes Replacement Considerations

Direct functional equivalents include the Vishay 1N5240B and onsemi 1N5240B. Verify that substitute parts match the DO-35 footprint and maintain the same 5% voltage tolerance and 500 mW power dissipation ratings before implementation.
