Product Details
CAP200DG-TL - Power Integrations CapZero™-2 Zero Loss Discharge IC
The CAP200DG-TL is a member of the CapZero™-2 family from Power Integrations. It is an intelligent, high-voltage integrated circuit designed to eliminate power loss in the switching power supply discharge resistors. By blocking current flow through the X-capacitor discharge path when AC is present, and automatically discharging the capacitor when AC is removed, the CAP200DG-TL helps designers achieve near-zero standby power consumption in high-power adapters and industrial supplies.
Efficiency Focus: Specifically engineered to meet stringent global energy efficiency standards such as EuP Lot 6 and CoC Tier 2 by reducing no-load losses.
Overview & Smart Discharge Technology
The CAP200DG-TL addresses a common efficiency drain in AC-DC converters: the safety discharge resistors. Traditionally, these resistors are always connected across the AC line, constantly wasting power. The CAP200DG-TL acts as a smart switch that stays open (blocking current) while the system is connected to the grid and closes instantly upon AC disconnection.
This 1000V rated device is placed in series with the discharge resistors. Because it is self-powered from the AC line, it requires no external bias supply, making it an easy "drop-in" addition to existing power supply layouts. The SO-8 (DG) package with the -TL (Tape & Reel) suffix is optimized for automated high-volume surface mount production.
About Power Integrations
Power Integrations, Inc. is a leading innovator in semiconductor technologies for high-voltage power conversion. Their products are fundamental building blocks in the clean-power ecosystem, enabling the creation of compact, energy-efficient power supplies for a vast range of electronic products.
Their CapZero™, LinkSwitch™, and InnoSwitch™ brands are synonymous with high integration and industry-leading reliability, helping manufacturers around the world meet and exceed evolving energy efficiency regulations.
Key Advantages
Eliminates virtually all power loss in X-capacitor discharge resistors when AC is connected.
High-voltage rating provides robust protection against line surges and transients.
Self-powers from the AC line, simplifying the bill of materials and PCB design.
Ensures the power supply complies with safety standards (IEC 62368-1/60950) for capacitor discharge times.
Package & Mechanical Specs
The CAP200DG-TL is available in a standard 8-pin SOIC (SO-8) package. This low-profile package is ideal for slim adapter designs and integrates well into standard manufacturing flows.
- Package Suffix: DG (SO-8).
- Shipping Format: TL (Tape and Reel).
- Moisture Sensitivity: MSL1 (Unlimited floor life).
- Safety Creepage: Designed to maintain isolation requirements between high-voltage nodes.
Pin Functions
The CAP200DG uses a symmetrical pinout to simplify PCB routing and ensure adequate high-voltage spacing.
