CMSZDA15V TR PBFREE

Overview

The CMSZDA15V TR PBFREE is a surface-mount Zener diode manufactured by Central Semiconductor Corp. It features a nominal breakdown voltage of 15 V with a maximum tolerance of ±5%. The device is rated for a maximum DC forward current of 200 mA and can dissipate up to 500 mW at an ambient temperature of 25°C. It operates within a junction temperature range of -65°C to +175°C and utilizes a SOD-323 package.

Feature Summary

• Surface-mount construction for automated assembly
• High thermal stability across extended temperature ranges
• Lead-free compliant packaging

Applications

• Voltage regulation in low-power circuits
• Clamping applications for transient protection
• Reference voltage sources in electronic systems

Procurement Notes

Verify the specific manufacturer part number against official datasheets to confirm electrical parameters and package type. Ensure compliance with RoHS directives if required by the application. Confirm availability through authorized distributors or direct manufacturer channels, as supply chain conditions may vary.

Selection Notes

Select this component based on the required 15 V Zener voltage and 500 mW power dissipation capability. Verify that the SOD-323 package dimensions fit the PCB layout constraints. Consider the operating temperature range and thermal management requirements for the specific circuit environment.

Part Context

This component belongs to the family of small-signal Zener diodes designed for voltage reference and protection roles. The 'TR' suffix indicates tape-and-reel packaging suitable for high-volume surface-mount production. The 'PBFREE' designation confirms the absence of lead in the manufacturing process.

Replacement Considerations

Cross-reference with other 15 V Zener diodes in the SOD-323 package from different manufacturers. Verify matching electrical characteristics such as breakdown voltage tolerance, power rating, and leakage current before substitution.
