STPS1L40A Description

Short technical summary and product information.

STMicroelectronics STPS1L40A is a Schottky rectifier diode designed for low-voltage, high-frequency applications. Schottky technology provides low forward voltage drop and fast switching performance, making it suitable for power supply and polarity protection circuits.

 

The diode is rated for a maximum reverse voltage of 40V and can handle an average forward current of 1A. At 1A forward current, the typical forward voltage is 500 mV. The maximum recovery time is 500 nanoseconds at 200 mA, enabling efficient operation in switching applications.

 

The STPS1L40A comes in a surface-mount DO-214AC (SMA) package, which simplifies PCB assembly and is widely used in compact designs. The junction operating temperature range is up to 150°C.

 

Key applications include DC-DC converters, freewheeling diodes, and reverse polarity protection in portable electronics.
