CMXD2004 TR PBFREE

Overview

The CMXD2004 TR PBFREE is a surface mount triple isolated high voltage silicon switching diode manufactured by Central Semiconductor Corp. It contains three independent diodes in an SOT-26 package. Key electrical ratings include a continuous reverse voltage of 240 V and a peak repetitive reverse voltage of 300 V per diode. The average forward current is 200 mA, with a power dissipation of 350 mW. Reverse leakage current is 100 nA at 240 V. Forward voltage is 1.0 V at 100 mA, and reverse recovery time is 50 ns.

Feature Summary

• Contains three electrically isolated high voltage silicon switching diodes within a single surface mount package.
• Designed for applications requiring high voltage capability using an epitaxial planar process.
• Features low reverse leakage current and fast switching characteristics suitable for high-speed circuits.

Applications

• High voltage switching circuits
• Isolated signal routing
• Multi-channel protection networks

Procurement Notes

Verify the specific ordering suffix to confirm plating configuration. The PBFREE suffix indicates lead-free plating, while TIN/LEAD indicates tin/lead plating. Confirm package type is SOT-26 and check datasheet for thermal resistance values during integration. Ensure design accounts for the maximum junction temperature range of -65°C to +150°C.

Selection Notes

Select this component when multiple isolated high-voltage switching paths are required in a compact footprint. The SOT-26 package accommodates three distinct diodes, reducing board space compared to individual components. Verify that the 300 V peak repetitive reverse voltage meets circuit requirements. Consider the 357 °C/W thermal resistance for heat dissipation planning in dense assemblies.
