CAP019DG

Specialized ICS Overview

The CAP019DG 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 resistance of 150 kW. The device operates in an 8-SO package with a surface mount configuration. It functions by blocking current flow during AC application to reduce standby power loss below 5 mW, then automatically discharging the capacitor upon AC removal. This self-supplied IC requires no external bias or ground connection.

Specialized ICS Feature Summary

• Zero-loss operation reduces standby power consumption to less than 5 mW at 233 VAC
• Self-supplied architecture 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 the specific ordering suffix when purchasing. The base model CAP019DG typically corresponds to tube packaging, while the TL suffix indicates tape and reel quantities of 2500 units. Confirm the package material designation 'G' for halogen-free and RoHS compliance requirements before finalizing orders.

Specialized ICS Selection Notes

Select the CAP019DG for applications requiring a 1000 V breakdown voltage rating. Ensure the external resistor network (R1 + R2) totals 150 kW to meet safety discharge time constants. Use this device when system MOV placement does not directly cross the X capacitor or when higher surge margins are required compared to the 825 V variants.

Specialized ICS Part Context

The CAP019DG belongs to the CapZero family of zero-loss automatic X capacitor discharge ICs. It shares the same SO-8 package dimensions and pinout as other family members like CAP018DG and CAP017DG, differing primarily in its internal breakdown voltage rating and associated external resistance specifications.

Specialized ICS Replacement Considerations

CAP019DG-TL serves as the tape and reel variant of this component.
