Product Overview
The CAP200DG-TL is a CAPZero-2 zero-loss automatic X capacitor discharge IC manufactured by Power Integrations. This device blocks current flow through X capacitor safety discharge resistors when AC voltage is applied, reducing power loss to below 5mW (near zero at 230VAC), and automatically discharges X capacitors via series resistors when AC power is disconnected. Widely deployed in AC-DC power supplies with X capacitors ranging from 100nF to 6mF, it optimizes EMI filtering while meeting strict energy efficiency standards. Complete operational parameters and application circuits are documented in the CAP200DG-TL datasheet.
Key Specifications
- X Capacitor Range: Supports 100nF to 6mF discharge applications
- Power Consumption: <5mW at 230VAC, near-zero standby loss
- Package Type: 8-pin SOIC surface-mount package
- Operating Voltage: Compatible with 85VAC to 265VAC systems
- Temperature Range: -10°C to +105°C industrial operation
- Surge Immunity: 1000V internal MOSFET, high common-mode surge tolerance
- Terminals: 2 active terminals, fuse-before/before installation compatible
Pinout & Package
The CAP200DG-TL utilizes an 8-SOIC (3.90mm width) surface-mount package with only 2 functional terminals for simplified integration. The package maintains >4mm creepage distance for safety compliance, with pins optimized for high-voltage isolation. Detailed pin configuration and PCB layout guidelines are available in the CAP200DG-TL pinout documentation, supporting direct solder mounting on standard FR-4 boards.
Key Features
- Near-zero power loss operation cuts standby consumption, ideal for energy-efficient adapters, delivering EuP Lot 6 compliance and reduced electricity usage
- Wide X capacitor coverage (100nF-6mF) simplifies EMI design, applicable to power supplies, enabling smaller inductors and lower BOM costs
- Self-powered architecture eliminates external bias, suitable for compact power modules, reducing component count and PCB space requirements
- High surge immunity (1000V) enhances reliability, perfect for industrial power systems, ensuring stable operation under voltage transients
