CAP019DG-TL

Specialized ICS Overview

The CAP019DG-TL is a specialized PMIC from the CapZero family designed for automatic X capacitor discharge. It features a 1000 V breakdown voltage and supports total series capacitance up to 5 mF with a nominal resistance of 150 kW. The device operates within an ambient temperature range of -10 °C to 105 °C, drawing a supply current of 21.7 mA at 25 °C. Packaged in an 8-SOIC (SO-8) format, it enables zero-loss standby power by blocking current flow during AC presence and automatically discharging capacitors upon disconnection.

Specialized ICS Feature Summary

• Zero-loss operation reduces standby power loss to less than 5 mW at 230 VAC
• Self-supplied design eliminates the need for external bias circuits
• High common mode surge immunity without requiring an external ground connection
• Internal MOSFETs withstand differential surges up to 1000 V

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 that the specific order suffix matches the required packaging configuration. Confirm the component meets the necessary safety standards for the target application region. Ensure the selected part number corresponds to the correct voltage rating and capacitance requirements for the system design.

Specialized ICS Selection Notes

Select the CAP019DG-TL when the application requires handling X capacitors up to 5 mF. This 1000 V variant is suitable for systems where the MOV is not placed directly across the X capacitor or where higher surge margins are needed. Ensure external resistors sum to 150 kW to meet the specified RC time constant.

Specialized ICS Part Context

This component belongs to the CapZero family of automatic X capacitor discharge ICs manufactured by Power Integrations. The family includes variants with 825 V and 1000 V ratings, differentiated by their maximum supported capacitance and internal resistance values to optimize EMI filtering and standby power performance.

Specialized ICS Replacement Considerations

CAP009DG-TL serves as a functional substitute for applications requiring lower capacitance support (up to 5 mF) but operating at a reduced 825 V breakdown voltage.
