STPS3170UF Ultrafast Diode from STMicroelectronics

The STPS3170UF is a cutting-edge ultrafast diode designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This power Schottky rectifier is specifically tailored for applications requiring high efficiency and fast switching performance. The device is particularly suitable for use in switch-mode power supplies, inverters, and as a freewheeling diode in various power applications.

One of the key features of the STPS3170UF is its very low forward voltage drop (VF), which significantly enhances the overall efficiency of the system in which it is deployed. This attribute, combined with the ultrafast recovery time, ensures that the diode can handle high-frequency operations without incurring excessive power losses.

Key Specifications:

• Average forward current (IF(AV)): 3 A
• Repetitive peak reverse voltage (VRRM): 170 V
• Non-repetitive peak forward surge current (IFSM): 100 A
• Forward voltage drop (VF) at IF(AV): Typically 0.77 V
• Operating junction temperature range (TJ): -40°C to 150°C
• Ultrafast reverse recovery time (trr)

The device is encapsulated in a PowerFLAT™ 5x6 package, which not only minimizes the PCB space requirement but also provides excellent thermal performance. The package is designed to be compatible with automated assembly processes, making it a convenient choice for high-volume manufacturing.

STMicroelectronics has also integrated robustness into the STPS3170UF, with features such as high junction temperature capability and a guaranteed avalanche rating. These characteristics make the diode a reliable component in even the most demanding environments.

For designers and engineers looking to improve the efficiency and performance of their power management systems, the STPS3170UF offers a compelling solution. Its combination of low power loss, high-speed switching, and space-saving design makes it an excellent choice for modern electronic applications.
