CAP005DG-TL

Specialized ICS Overview

The CAP005DG-TL is a specialized power management IC from the CapZero family, designed for automatic X capacitor discharge in AC-DC converters. It features an 825 V breakdown voltage and supports total series resistance of 480 kW to handle up to 1.5 mF capacitance. The device operates in a surface-mount 8-SOIC package with a supply current of 21.7 uA at 25 °C. Drain saturation current is specified at 0.78 mA. It functions without external bias, providing high common mode surge immunity and differential surge withstand capability.

Specialized ICS Feature Summary

• Zero-loss operation reduces standby power loss to less than 5 mW when AC voltage is applied
• Self-supplied design eliminates the need for external bias circuits or ground connections
• High differential surge withstand capability utilizing internal 1000 V MOSFETs
• Compliant with IEC 62301 clause 4.5 standards for ultra-low no-load consumption

Specialized ICS Applications

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

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'TL' corresponds to the Tape & Reel packaging configuration containing 2,500 pieces per reel. Confirm that the 'G' suffix indicates a Green, halogen-free, and RoHS-compliant plastic SO-8 package variant. Ensure the selected component matches the required 825 V breakdown voltage rating for the target application's surge specifications.

Specialized ICS Selection Notes

Select the CAP005DG-TL for applications requiring a maximum total X capacitance of 1.5 mF with a total series resistance of 480 kW. This 825 V grade is suitable for systems where the MOV is placed directly across the X capacitor (MOVPOS1) with surge requirements up to 3 kV. For higher surge voltages exceeding 1.5 kV or if additional voltage margin is needed, consider the 1000 V alternative within the family.

Specialized ICS Part Context

The CAP005DG-TL belongs to the CapZero family of zero-loss automatic X capacitor discharge ICs manufactured by Power Integrations. This family enables designers to optimize EMI filtering and reduce inductor costs by allowing larger X capacitors without increasing standby power consumption. The device simplifies safety compliance by automatically discharging capacitors below SELV levels upon AC removal.

Specialized ICS Replacement Considerations

For equivalent 825 V performance with different capacitance limits, consider the CAP004DG-TL (1 mF, 780 kW) or the CAP006DG-TL (2 mF, 360 kW). If the application requires higher surge withstand capabilities above 3 kV, the 1000 V rated CAP015DG-TL serves as the direct voltage-grade alternative within the same package.
