Product Details
CAP017DG-TL - CAPZero Automatic X-Capacitor Discharge IC
CAP017DG-TL from Power Integrations is a 1000 V automatic X-capacitor discharge controller for AC-DC inputs, rated for X capacitors up to 2.5 uF, in tape-and-reel SOIC-8.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
CAPZero disconnects the safety discharge resistors while AC mains is present and reconnects them after line removal, reducing standby loss while preserving required X-capacitor discharge behavior.
Key Advantages
Eliminates continuous resistor loss to support very low no-load input power.
Self-powered two-terminal operation simplifies placement before or after the input fuse.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Zero-loss automatic X-capacitor discharge
Two-terminal mains-sensing connection in series with X-capacitor discharge resistors
1000 V internal MOSFETs; X capacitance up to 2.5 uF; -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
CAP017DG 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
Exact order code and manufacturer documentation were checked.
Applications
Discharges the differential-mode X capacitor after the mains input is removed.
Removes the continuous power penalty of conventional discharge resistors.
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.
