1N5224B BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5224B BK TIN/LEAD is a hermetically sealed glass Zener diode designed for through-hole mounting. It features a DO-35 axial package with tin/lead terminations and a polarity band indicating the cathode. The device provides a nominal Zener voltage of 2.8 V with a ±5% tolerance at a test current of 20 mA. It dissipates up to 500 mW, exhibits a maximum reverse leakage current of 75 µA at 1 V, and has a Zener impedance of 30 Ω. Operating temperatures range from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead finish and packaging format. Confirm RoHS compliance status as standard manufacturing practices may vary by production batch. Ensure the component meets environmental requirements for the intended deployment environment before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference near 2.8 V is required in a ruggedized through-hole form factor. The hermetic seal makes it suitable for harsh environments where moisture resistance is critical. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target circuit board layout.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5263B series of small signal Zener diodes manufactured by Central Semiconductor. These components are characterized by their glass passivation and axial leaded package, providing reliable performance in space-constrained applications requiring stable voltage regulation.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5224B designation in a DO-35 package. Verify that substitute parts match the 2.8 V nominal voltage, 500 mW power rating, and hermetic sealing requirements to ensure functional compatibility.
