CAP004DG-TL

Specialized ICS Overview

The CAP004DG-TL is a specialized PMIC from the CapZero family designed for automatic X capacitor discharge. It features an 825 V breakdown voltage and supports total series resistance of 780 kW, enabling compatibility with up to 1 mF capacitance. The device operates in SO-8 packages and requires no external bias supply. It reduces standby power loss to less than 5 mW at 230 VAC by blocking current flow during AC application and automatically discharging capacitors upon disconnection.

Specialized ICS Feature Summary

• Zero-loss operation blocks current in safety discharge resistors when AC is present
• Self-supplied design eliminates the need for external bias circuits
• High common mode surge immunity without requiring external ground connections
• Compliant with EuP Lot 6 requirements for ultra-low no-load consumption

Specialized ICS Applications

• AC/DC converters requiring compliance with EuP Lot 6 standards
• Appliances needing ultra-low standby power consumption
• Adapters optimized for minimal no-load energy usage

Specialized ICS Procurement Notes

Verify that the selected component matches the specific voltage grade (825 V) required for the target circuit's surge specifications. Confirm package availability aligns with manufacturing needs, as the standard configuration includes tape and reel packaging options.

Specialized ICS Selection Notes

Select the CAP004DG-TL for applications utilizing X capacitors up to 1 mF with a total series resistance of 780 kW. Ensure the system MOV placement allows for adequate voltage withstand, as this 825 V variant is suitable for surge requirements typically up to 3 kV or more when positioned correctly.

Specialized ICS Part Context

This component belongs to the CapZero family of zero-loss automatic X capacitor discharge ICs manufactured by Power Integrations. The family provides two voltage grades (825 V and 1000 V) to accommodate different surge environments while maintaining consistent functionality for reducing standby power in offline power supplies.

Specialized ICS Replacement Considerations

CAP014DG serves as the 1000 V alternative within the same family. Verify if higher surge immunity is necessary; otherwise, the 825 V rating of the CAP004DG-TL is sufficient for most standard configurations.
