CAP009DG-TL

Specialized ICS Overview

The CAP009DG-TL is a specialized power management IC from the CapZero family, designed for automatic X capacitor discharge. It features an 825 V breakdown voltage and supports total series resistance of 150 kW. The device operates with a supply current of 21.7 uA at 25 °C and functions within an ambient temperature range of -10 °C to 105 °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 or effectively zero at 230 VAC.
• Self-supplied architecture requires no external bias voltage or ground connection.
• High common mode surge immunity and 1000 V internal MOSFET differential withstand capability.
• Complies with 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 the 'TL' suffix indicates Tape & Reel packaging containing 2,500 pieces per reel. Confirm the 'G' suffix denotes Green, halogen-free, and RoHS-compliant material specifications. Ensure the component meets the required 825 V breakdown voltage rating for the specific circuit configuration.

Specialized ICS Selection Notes

Select this model when the system requires an 825 V breakdown voltage and a total series resistance of 150 kW. Verify that the MOV placement allows the 825 V option to handle surge requirements up to 3 kV. Ensure the PCB layout maintains over 4 mm creepage distance between pins 1-4 and 5-8.

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 variants with 825 V and 1000 V ratings, differentiated by supported capacitance and resistance values. The CAP009DG specifically targets applications needing higher resistance values compared to lower-capacitance counterparts.

Specialized ICS Replacement Considerations

CAP019DG serves as the 1000 V equivalent within the same family. Other models like CAP008DG offer different resistance values (200 kW). Verify voltage ratings and resistance specifications before substitution.

Specialized ICS FAQ

How does the CAP009DG manage standby power?

It blocks current flow in safety discharge resistors when AC voltage is applied, reducing power loss to less than 5 mW, and automatically connects resistors to discharge the capacitor when AC is disconnected.

What is the recommended MOV placement for the 825 V version?

For the 825 V option, the system MOV should typically be placed directly across the X capacitor (MOVPOS1) to provide adequate withstand for surge requirements up to 3 kV or more.

Does the device require an external ground connection?

No, the CAPZero IC provides high common mode surge immunity without requiring an external ground connection.
