The DB201S is a surface-mount bridge rectifier commonly used in electronic circuits for converting alternating current (AC) to direct current (DC). It typically has a 4-pin configuration. The pins are:
1. AC Input 1 (Pin 1): This is one of the two AC input pins where the AC voltage is applied.
2. AC Input 2 (Pin 2): The second AC input pin for applying AC voltage.
3. DC Output Positive (Pin 3): The output pin where the rectified DC positive voltage is obtained.
4. DC Output Negative (Pin 4): The output pin for the rectified DC negative voltage.
The DB201S rectifier generally supports a maximum reverse voltage of 100V and a forward current of about 2A, making it suitable for low to medium power applications in electronic devices.

The DB201S is manufactured by Audio Technica, a company known for producing audio equipment. Audio Technica is a Japanese corporation that specializes in a broad range of audio products, including high-performance microphones, headphones, phonographic magnetic cartridges, and other professional audio equipment. The company was founded in 1962 and has since become a reputable name in the audio industry, recognized for its commitment to quality and innovation.
