CDSQR4148 Description

Short technical summary and product information.

The Comchip Technology CDSQR4148 is a standard switching diode designed for general purpose rectification and switching applications. It is rated for a maximum reverse voltage of 75V and an average forward current of 150mA, making it suitable for low-power circuits.

 

The device offers a low forward voltage drop of 1V at 50mA and a fast reverse recovery time of 4ns under specified conditions. It can handle a peak forward surge current of 4A for 1us. The typical junction capacitance is 4pF at 0V and 1MHz.

 

The diode is supplied in a compact 0402/SOD-923F surface mount package, which is ideal for high-density PCB designs. The package measures approximately 1.0mm x 0.55mm with a height of 0.45mm. The terminals are gold plated for reliable solderability.

 

The CDSQR4148 is RoHS compliant and halogen free, meeting environmental standards. Its operating temperature range is from -40°C to +125°C, and it dissipates up to 125mW. This diode is commonly used in signal switching, polarity protection, and high-speed switching circuits.
