2W10 1000V 2A Single Phase Bridge Rectifier

2W10 1000V 2A Single Phase Bridge Rectifier is a robust and efficient discrete semiconductor component designed to convert alternating current (AC) into direct current (DC) for a wide variety of power supply applications. This high-voltage bridge rectifier features four internally connected silicon diodes arranged in a bridge configuration. Consequently, it provides full-wave rectification, which ensures a much smoother output voltage compared to half-wave alternatives. The device handles a maximum repetitive peak reverse voltage of 1000 V and supports a continuous forward current of 2 A. Furthermore, its compact circular design and through-hole mounting style make it an ideal choice for space-constrained printed circuit boards (PCBs). Therefore, you should utilize the 2W10 bridge rectifier when your project requires a reliable, high-voltage rectification stage with a small mechanical footprint.

Key Features:

• High Voltage Rating: The device safely withstands up to 1000 V in the reverse direction, making it suitable for mains-operated equipment.
• Low Forward Voltage Drop: Each internal diode minimizes power loss by maintaining a low forward voltage, which enhances overall system efficiency.
• High Surge Current Capability: It handles high peak forward surge currents, preventing damage during initial power-on or capacitive charging.
• Integrated Bridge Design: The single-package solution replaces four individual diodes. Consequently, it simplifies circuit board layout and reduces assembly costs.
• Reliable Construction: Encapsulated in a flame-retardant plastic case (UL 94V-0), the component ensures long-term durability in industrial environments.
