CMOZ20L TR PBFREE

Single Zener Diodes Overview

The CMOZ20L TR PBFREE is a surface-mount low-level silicon Zener diode from the CMOZ1L8 series by Central Semiconductor Corp. It operates within a voltage range of 1.8 to 47 volts and features a maximum power dissipation of 250 mW with a 5% tolerance. The device utilizes an SOD-523 (ULTRAmini) epoxy-molded package, designed for applications requiring extremely low operating current and leakage. Key electrical parameters include a nominal Zener voltage of 20 V at a test current of 250 µA, a maximum Zener impedance of 150 Ω, and a maximum reverse current of 22 µA at 18 V.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging and 'PBFREE' indicates lead-free plating as specified in manufacturer documentation. Confirm the component matches the CMOZ1L8 series specifications before procurement. Ensure compatibility with standard surface mount assembly equipment. Cross-reference the marking code 'P3' with official datasheets to validate authenticity and part identity during receiving inspection.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V reference is required in a compact surface mount footprint. The 250 mW power rating and 5% voltage tolerance suit general-purpose regulation tasks. Consider the specific Zener impedance and reverse leakage characteristics for sensitive low-current circuit designs. Verify thermal resistance requirements against the intended operating environment.

Single Zener Diodes Part Context

This component belongs to the CMOZ1L8 series, which encompasses Zener diodes ranging from 1.8 V to 47 V. All devices in this series share identical physical dimensions and package types but vary in nominal voltage and associated electrical parameters. The series is engineered for consistent performance across various voltage levels while maintaining a standardized form factor for automated manufacturing.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other CMOZ variants sharing the SOD-523 package and 250 mW rating. Verify that alternative part numbers match the required nominal voltage and tolerance specifications. Ensure any replacement maintains the same thermal and electrical characteristics defined in the original datasheet.
