DF10S2

DF10S2 Description

The DF10S2 from onsemi is a single-phase bridge rectifier designed for high-efficiency AC-to-DC conversion in compact, surface-mount applications. With a peak reverse voltage (VRRM) of 1 kV and an average rectified current (Io) of 2 A, this device is engineered for reliability in demanding circuits. Its low forward voltage drop (1.1 V max @ 2 A) minimizes power loss, while the reverse leakage current of just 3 µA @ 1000 V ensures superior blocking performance. Packaged in a 4-SDIP (Surface Mount DIP) and supplied in Tape & Reel (TR), the DF10S2 is optimized for automated assembly processes. Although marked as Obsolete, it remains a robust choice for legacy designs due to its ROHS3 compliance and REACH unaffected status.

DF10S2 Features

• High Voltage Handling: Supports up to 1 kV peak reverse voltage, ideal for industrial and high-voltage applications.
• Low Power Dissipation: 1.1 V max forward voltage at 2 A reduces thermal stress.
• Minimal Leakage: 3 µA reverse leakage at full rated voltage enhances efficiency.
• Surface-Mount Design: 4-SDIP package saves PCB space and suits high-density layouts.
• Compliance: ROHS3 compliant and REACH unaffected, meeting modern environmental standards.
• Wide Operating Range: Standard silicon technology ensures stable performance across temperatures.

DF10S2 Applications

The DF10S2 excels in:

• Power Supplies: AC-DC conversion in SMPS, adapters, and LED drivers.
• Industrial Equipment: Rectification for motor controls, PLCs, and instrumentation.
• Consumer Electronics: Compact designs like battery chargers and home appliances.
• Legacy Systems: Maintenance and repair of older electronics requiring high-voltage rectification.

Conclusion of DF10S2

The DF10S2 bridge rectifier balances high-voltage capability, low leakage, and compact packaging, making it a dependable choice for efficient power conversion. While obsolete, its proven performance and compliance with environmental standards ensure relevance in legacy and niche applications. Engineers seeking a surface-mount, high-voltage rectifier with low losses will find the DF10S2 a technically sound solution.
