CLL4625 BK

Single Zener Diodes Overview

The CLL4625 BK is a silicon Zener diode from the CLL4614 series, designed for low leakage and low noise applications. It features a 5.1 V nominal Zener voltage with a 5% tolerance. The device operates in an SOD-80 surface mount package and dissipates up to 500 mW at 25°C ambient temperature. Key electrical parameters include a maximum reverse leakage current of 10 µA at 3.0 V, a maximum Zener impedance of 1500 Ω at the test current of 250 µA, and a maximum noise density of 2.0 µV/√Hz.

Single Zener Diodes Feature Summary

• Engineered for low leakage and low noise performance suitable for sensitive signal paths
• Utilizes a compact SOD-80 surface mount glass encapsulation
• Provides stable voltage regulation with a standard 5% tolerance

Single Zener Diodes Applications

• Low noise voltage reference circuits
• Precision voltage regulation in small form factor designs
• Signal conditioning requiring minimal leakage current

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements when ordering, as plating options such as TIN/LEAD or PBFREE may be requested by adding the corresponding suffix to the part number. Confirm availability status directly with Central Semiconductor Corp., as distribution channels may vary. Ensure the procurement documentation matches the exact CLL4625 designation to avoid confusion with similar series components.

Single Zener Diodes Selection Notes

Select this component for designs prioritizing low noise characteristics over higher power handling capabilities. The SOD-80 package constrains thermal dissipation to 500 mW, necessitating careful layout considerations. Verify that the 1500 Ω maximum impedance meets the circuit's stability requirements, particularly at the specified 250 µA test current condition.

Single Zener Diodes Part Context

This device belongs to the CLL4614 through CLL4627 series of surface mount silicon Zener diodes manufactured by Central Semiconductor Corp. The series shares common design goals focused on low leakage and low noise operation within a standardized SOD-80 footprint. These components are intended for general-purpose voltage regulation where size and electrical purity are critical constraints.
