CAP012DG-TL

Specialized ICS Overview

The CAP012DG-TL is a specialized power management IC from the CapZero family, designed for automatic X capacitor discharge in AC-DC converters. It features a 1000 V breakdown voltage and supports total X capacitance up to 500 nF with a series resistance of 1.5 MW. The device operates within an ambient temperature range of -10 °C to 105 °C and draws a supply current of 21.7 mA at 25 °C. Packaged in an 8-SOIC (SO-8) format, it eliminates standby power loss by blocking current flow during AC application and automatically discharging capacitors upon disconnection.

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 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 the specific ordering suffix 'TL' corresponds to the Tape & Reel packaging containing 2500 pieces as defined in the manufacturer's part numbering system. Confirm that the component meets RoHS standards and is halogen-free. Ensure the selected package variant matches the required surface mount assembly specifications for the target PCB layout.

Specialized ICS Selection Notes

Select the CAP012DG-TL when the application requires a 1000 V breakdown voltage rating. This model is appropriate for systems where the MOV placement or surge requirements necessitate higher voltage margins compared to the 825 V variants. Ensure the total X capacitance does not exceed 500 nF and the associated series resistance aligns with the 1.5 MW specification for safe discharge timing.

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 includes various voltage grades and capacitance ratings to accommodate different EMI filter designs. The CAP012DG-TL specifically addresses high-voltage applications within this lineup, offering a solution for safety compliance without increasing standby power consumption.

Specialized ICS Replacement Considerations

The CAP014DG-TL serves as a direct functional replacement within the same family, sharing identical electrical characteristics including the 1000 V breakdown voltage and SO-8 package configuration.
