Product Details
CAP019DG-TL - CAPZero Automatic X-Capacitor Discharge IC
CAP019DG-TL from Power Integrations is an automatic X-capacitor discharge controller for AC mains applications in an 8-lead SO package, supplied on tape and reel.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
CAP019 monitors the AC input and disconnects the discharge resistors while mains voltage is present, then safely discharges the X capacitor when the input is removed.
Key Advantages
Reduces standby loss from conventional X-capacitor discharge resistors to below 5 mW at 230 VAC.
Supports high-voltage mains applications with an internal 1000 V device rating.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Automatic X-capacitor discharge controller
Mains-sense and external discharge-resistor connections
Up to 1000 V internal rating; -10 C to +105 C
8-SOIC (0.154", 3.90mm Width)
Package & Footprint
This ordering code uses the 8-SOIC (0.154", 3.90mm Width) package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
CAP014DG-TL is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Power Integrations lists CAP019 as an active CAPZero device. The linked CAP014 is related but resistor selection and qualification must be checked; it is not asserted as a drop-in replacement.
Applications
Discharges the EMI X capacitor after AC removal while minimizing normal-operation loss.
Helps meet discharge-time and standby-power requirements in mains-powered equipment.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
