MBR5100MFST1G Description

Short technical summary and product information.

The MBR5100MFST1G from On Semiconductor (onsemi) is a 100-volt, 5-ampere Schottky barrier rectifier diode designed for switch-mode power supply and high-frequency rectification applications. It is housed in a compact surface-mount 5-DFN (8-PowerTDFN, 5 leads) package, enabling automated assembly and space-efficient board layouts.

 

Key electrical specifications include a maximum average rectified forward current of 5 A at 165°C case temperature, a peak repetitive forward current of 10 A, and a non-repetitive surge current rating of 75 A. The forward voltage drop is typically 0.98 V at 5 A, which contributes to low conduction losses. The device operates across a junction temperature range of -55°C to +175°C, with a storage temperature range of -65°C to +175°C.

 

The MBR5100MFST1G incorporates guardring for stress protection and meets MSL 1 (unlimited) moisture sensitivity level. It is lead-free (Pb-Free) and available in tape-and-reel packaging with 1500 pieces per reel. The part is also offered as the NRVB5100MFST1G automotive-qualified variant and the MBR5100MFST3G for larger reel quantities.
