B0540WQ-7-F Description

Short technical summary and product information.

The B0540WQ-7-F from Diodes Incorporated is a 0.5A surface mount Schottky barrier rectifier designed for applications requiring low forward voltage drop and high current capability. With a maximum repetitive reverse voltage of 40V and an average rectified current of 500mA, this device offers a forward voltage of just 510mV at 500mA. The reverse leakage current is limited to 10µA at 40V, ensuring efficient operation.

 

Key electrical characteristics include a typical junction capacitance of 170pF at 0V and 1MHz, and a non-repetitive peak forward surge current rating of 5.5A for 8.3ms single half sine-wave. The device features guard ring construction for enhanced transient protection and fast recovery speed typical of Schottky diodes.

 

This rectifier is qualified to AEC-Q101 standards for high reliability automotive applications. It is fully RoHS3 compliant, lead-free, and halogen-free. The device is packaged in a compact SOD-123 case with matte tin finished terminals, rated for -65°C to 150°C operating junction temperature. Typical thermal resistance is 385°C/W (junction to ambient) under standard conditions.
