BUZ11A Description

Short technical summary and product information.

The Siemens BUZ11A is a high-performance N-Channel MOSFET belonging to the STripFET family. It is engineered for demanding applications requiring high current capability and fast switching speeds.

Key electrical specifications include a drain-source breakdown voltage of 50V and a continuous drain current of 26A at 25°C. The typical static drain-source on-resistance (RDS(on)) is a low 0.045 Ohms at 10V gate-source voltage and 19A drain current, minimizing conduction losses. Avalanche ruggedness is a notable feature, with 100% avalanche testing and a single pulse avalanche energy rating of 120 mJ.

This MOSFET operates within a wide temperature range, from -65°C to 175°C, making it suitable for harsh environments. The TO-220 package facilitates through-hole mounting and provides adequate thermal dissipation, with a junction-to-case thermal resistance of 1.67°C/W.

Applications for the BUZ11A include high current, high speed switching, solenoid and relay drivers, regulators, DC-DC and DC-AC converters, motor control, and audio amplifiers. It is also well-suited for automotive environments, including injection systems, ABS, and airbag applications.
