1N5250B BK TIN/LEAD

Single Zener Diodes Overview

The 1N5250B BK TIN/LEAD is a single Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 9.1 V with a 5% tolerance, resulting in a range of 8.645 V to 9.555 V. The device operates in a DO-35-2 through-hole package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 3 µA, a Zener impedance of 10 ohms at a test current of 20 mA, and an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within a tight 5% tolerance band for precision applications.
• Utilizes a glass axial-lead DO-35 package designed for high-temperature reliability up to 200°C.
• Offers low leakage current characteristics to minimize power loss in reverse bias conditions.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix BK TIN/LEAD against the manufacturer's latest datasheet to confirm lead composition and marking codes. Ensure the DO-35-2 package dimensions match the target PCB footprint. Confirm RoHS compliance status as tin/lead variants may differ from lead-free equivalents in regulatory documentation.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V regulation point is required with moderate power handling capabilities. The DO-35 package suits through-hole assembly processes. Consider the 10 ohm impedance for dynamic load variations. Verify that the 500 mW dissipation rating aligns with the thermal environment of the final enclosure design.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of 500 mW Zener diodes produced by Central Semiconductor. The series covers a wide voltage range using the same physical form factor. The 1N5250B designation specifically identifies the 9.1 V variant within this family, sharing common testing standards and mechanical specifications with adjacent voltage ratings.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5250B equivalents in DO-35 packages. Verify that substitute parts meet the 5% voltage tolerance and 500 mW power rating. Check for identical pinout compatibility and thermal performance characteristics before integration.
