CAP002DG-TL

Specialized ICS Overview

The CAP002DG-TL is a zero-loss automatic X capacitor discharge IC from the CapZero family by Power Integrations. Designed for AC-DC converters, it blocks current flow in safety discharge resistors during AC operation to reduce standby power loss below 5 mW at 230 VAC. Upon AC disconnection, it automatically connects internal series resistors to discharge the X capacitor. The device features an 825 V breakdown voltage and supports maximum total X capacitance of 500 nF with a total series resistance of 1.5 MW. It operates within an ambient temperature range of -10 °C to 105 °C and is housed in an 8-SOIC package.

Specialized ICS Feature Summary

• Zero-loss operation reduces standby power consumption to less than 5 mW at 230 VAC
• Self-supplied design requires no external bias circuitry
• High common mode surge immunity eliminates need for external ground connection
• Meets IEC 62301 clause 4.5 standards for ultra-low no-load consumption

Specialized ICS Applications

• Appliances requiring EuP Lot 6 compliance
• Adapters requiring ultra low no-load consumption
• Converters requiring very low standby power

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance and halogen-free status as specified in the ordering suffix 'G'. Ensure packaging matches Tape & Reel (TR) specifications for automated assembly processes.

Specialized ICS Selection Notes

Select the 825 V grade for applications where the system MOV is placed directly across the X capacitor, supporting surge requirements up to 3 kV. Ensure the total external resistance equals 1.5 MW to meet the required RC time constant for safety discharge. Verify that the peak drain voltage remains below the breakdown limit during surge testing.

Specialized ICS Part Context

The CAP002DG-TL belongs to the CapZero family, which provides flexible X capacitor selection for EMI filtering without increasing power consumption. This specific part number indicates the 002 series variant with a plastic SO-8 package, green material composition, and tape & reel delivery format.

Specialized ICS Replacement Considerations

The CAP012DG serves as the 1000 V alternative within the same family. Selection depends on whether the application requires higher voltage margin or different surge placement configurations.
