CMOZ1L8 TR PBFREE

Single Zener Diodes Overview

The CMOZ1L8 TR PBFREE is a surface-mount low-level silicon Zener diode from Central Semiconductor, housed in an SOD-523 package. It provides a nominal Zener voltage of 1.8 V with a 5% tolerance range (1.71 V to 1.89 V). The device operates at a test current of 250 µA and dissipates up to 250 mW. Key electrical parameters include a maximum Zener impedance of 1400 Ω and a maximum reverse leakage current of 25 µA at 1.0 V. It supports operating temperatures from -65°C to +150°C.

Single Zener Diodes Feature Summary

• Designed for applications requiring extremely low operating currents and minimal leakage.
• Utilizes an epoxy-molded ULTRAmini™ package for compact surface-mount integration.
• Provides stable voltage regulation within a tight 5% tolerance band.

Single Zener Diodes Applications

• Low-level voltage regulation circuits
• Reference voltage generation
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'TR PBFREE' corresponds to the required tape-and-reel packaging and lead-free plating specifications. Confirm that the SOD-523 footprint matches the target PCB design. Ensure the procurement documentation explicitly references the Central Semiconductor datasheet for the CMOZ1L8 Series to validate the 1.8V nominal rating and associated electrical limits.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand precise low-voltage clamping or reference levels in space-constrained environments. The SOD-523 form factor allows for high-density mounting. Engineers should account for the relatively high Zener impedance of 1400 Ω, which may influence regulation accuracy under varying load conditions compared to lower-impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the CMOZ1L8 through CMOZ47L series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a wide voltage range from 1.8 V to 47 V, all sharing similar physical dimensions and power dissipation characteristics within the ULTRAmini™ package family.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 1.8V nominal Zener voltage, SOD-523 package, and 250mW power rating. Verify compatibility regarding maximum Zener impedance and reverse leakage current specifications to ensure equivalent performance in sensitive low-current applications.
