This product is MBR120ESFT1/D Surface Mount Schottky Power Rectifier Plastic SOD-123 Package, using the Schottky Barrier principle, suitable for low voltage, high frequency rectification or as free wheeling and polarity protection diodes for surface mount applications where compact size and weight are critical to the system. This package also provides an easy to work with alternative to leadless 34 package style. Because of its small size, it is ideal for use in portable and battery powered products such as cellular and cordless phones, chargers, notebook computers, printers, PDAs and PCMCIA cards.
The MBR120ESFT1 Schottky power rectifier is designed for low‑voltage, high‑frequency applications such as AC‑DC converters, reverse‑battery protection, and portable devices. Its compact SOD‑123FL plastic package and low leakage make it suitable for space‑constrained, battery‑powered products.
Key features include a guard‑ring for stress protection, operation up to 150 °C junction temperature, and ESD ratings of Machine Model 0.5 kV and Human Body Model 3 kV. The datasheet provides detailed electrical, thermal, and mechanical specifications, as well as ordering information and packaging options.
