Additional Details:

The DAN202S3 is typically surface-mounted on a printed circuit board (PCB). It operates by diverting excess voltage away from protected components during a transient voltage event. The clamping voltage is a crucial parameter that determines the effectiveness of the TVS diode in protecting sensitive electronics. The device's surge capability indicates the maximum surge current it can safely handle without being damaged. Consult the datasheet for specific electrical characteristics, package dimensions, and application recommendations. The device should be placed as close as possible to the protected component for optimal performance.
