The SDM0520S is a surface-mount SOT-23 device manufactured by Diotec that combines two Schottky diodes and a rectifier on one chip. This device has a peak repetitive reverse voltage of 20V and a maximum average forward current of 0.5A. Its Schottky diodes provide higher switching speeds and low power consumption than traditional low-power diodes. The rectifier provides high avalanche and reverse breakdown voltage capabilities, making it suitable for high-voltage protection applications. This device is well suited for automotive and telecom applications requiring high-speed, low-power, and high voltage protection.
