SDM20U40-7 Description

Short technical summary and product information.

The SDM20U40-7 is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated. It is designed for low-voltage, high-speed switching applications requiring minimal power loss.

 

Key electrical specifications include a maximum reverse voltage (VRRM) of 40V, a maximum RMS reverse voltage of 28V, and a maximum forward continuous current (IF) of 250mA. The diode exhibits a low forward voltage drop of 0.35V at 10mA and 0.37V at 20mA, with a maximum of 0.60V at 200mA. Reverse leakage current is limited to 5µA at 30V and 1µA at 10V. The device offers a typical capacitance of 50pF at 0V and 1MHz, and a reverse recovery time of 10ns.

 

The SDM20U40-7 is housed in an ultra-small SOD523 surface-mount package, weighing approximately 0.002 grams. It is rated for operation over a temperature range of -65°C to 150°C. The component is totally lead-free, RoHS3 compliant, halogen and antimony free, and classified as a green device. Moisture sensitivity is Level 1 per J-STD-020, and the molding compound has a UL flammability rating of 94V-0.
