Product Details
CAP200DG-TL - CapZero-2 Zero-Loss Automatic X-Capacitor Discharge IC (SO-8)
CAP200DG-TL is a smart, high-voltage automatic discharge IC from the CapZero-2 family by Power Integrations. It is designed to eliminate power losses in the X-capacitor discharge resistors of switching power supplies, enabling compliance with strict standby energy standards like EuP Lot 6.
This page is written for product identification and engineering selection guidance. Always verify final limits using the manufacturer's latest datasheet revision for design sign-off.
Overview
CAP200DG-TL addresses the common design challenge of meeting safety discharge requirements without sacrificing efficiency. In traditional designs, bleed resistors constantly waste power. The CapZero-2 IC blocks current flow through these resistors when AC is present and automatically connects them when AC is disconnected.
With a typical consumption of less than 5mW at 230VAC, this device effectively reduces discharge path loss to zero. It features an integrated 1000V MOSFET, providing high reliability and robustness against line surges, making it suitable for a wide range of AC-DC converters.
Key Advantages
Eliminates continuous power loss in EMI filter bleed resistors, staying under 5mW at high line voltages.
Meets NEMKO and CB safety certifications (IEC 62368-1 / IEC 60950) for automatic X-capacitor discharge.
Integrated 1000V MOSFETs handle line transients and surges with high confidence.
Self-supplied two-terminal device requires no external bias or ground connection, simplifying PCB layout.
Feature Summary
Designed for universal mains applications (85V to 265V AC).
Fast detection (typically <22ms) ensures safe capacitor discharge within regulatory timeframes.
Optimized for ultra-low no-load and standby power consumption standards globally.
Internal logic prevents false triggering and ensures reliable operation across temperature ranges.
Package & Footprint
The CAP200DG-TL is supplied in an 8-pin SO-8 (D Package) format. This surface-mount package is designed with high creepage and clearance in mind to handle 1000V internal potentials.
- Pins 1, 4, 5, and 8 are typically not connected internally (NC) but should be handled per datasheet layout tips.
- Ensure >4.0mm creepage distance between the discharge resistor terminals on the PCB.
- Follow manufacturer guidelines for moisture sensitivity levels (MSL) during assembly.
Pin Functions
The CAP200DG-TL uses a specific terminal arrangement where pairs of pins are tied together on the PCB to facilitate the high-voltage discharge path.
