LZ52C18W

Single Zener Diodes Overview

The LZ52C18W is a surface-mount Zener diode manufactured by Diodes Incorporated, housed in a 1206 package. It provides a nominal Zener voltage of 18 V with a tolerance of ±2%. The device dissipates up to 500 mW and operates within a temperature range of -65°C to +175°C. Electrical characteristics include a maximum reverse current of 0.1 µA at 13 V and a maximum Zener impedance of 50 Ω at a test current of 5 mA.

Single Zener Diodes Feature Summary

• Utilizes an ultra-small 1206 surface-mount package for compact circuit integration
• Features silicon epitaxial planar construction with low-leakage current capabilities
• Offers high-precision voltage regulation with a tight ±2% tolerance on Zener voltage

Single Zener Diodes Applications

• General-purpose voltage regulation functions
• Surface-mounted electronic designs requiring precise reference voltages

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance and Halogen-free status against specific project requirements. Ensure the ordering suffix matches the required packing quantity and carrier type. Review the datasheet revision history for any updates to electrical parameters or mechanical dimensions prior to final procurement.

Single Zener Diodes Selection Notes

Select this component when a 1206 footprint is mandated and a 18 V reference is needed. The ±2% tolerance distinguishes it from standard ±5% variants. Evaluate thermal derating curves if operating near the maximum power dissipation limit. Consider the recommended replacement BZT52C18S-7-F if the 1206 package is unavailable or obsolete.

Single Zener Diodes Part Context

This part belongs to the LZ52C series of surface-mount Zener diodes designed for general regulation applications. The series covers a wide voltage range from 4.7 V to 36 V. The 'W' suffix typically denotes the specific 1206 package variant within the lineup. These devices are intended for automated surface-mount assembly processes.

Single Zener Diodes Replacement Considerations

The datasheet explicitly states that the LZ52C4V7W - LZ52C36W(LS) series is not recommended for new designs. Customers are advised to contact the manufacturer for alternative solutions. No specific substitute part numbers are listed in the provided documentation.
