FDD3706 Description

Short technical summary and product information.

The FDD3706 is a 20V N-Channel PowerTrench MOSFET designed for high efficiency in DC/DC converters and motor drive applications. It features a drain-source breakdown voltage of 20V and a continuous drain current of 14.7A at ambient temperature (Ta=25°C) and 50A at case temperature (Tc=25°C). The device achieves a low on-resistance of 9mOhm maximum at Vgs=10V and Id=16.2A, with typical values of 7.5mOhm at 10V and 8mOhm at 4.5V. Gate charge is typically 16nC, enabling fast switching. Input capacitance is 1882pF typical at Vds=10V. The MOSFET is housed in a surface-mount TO-252 (DPAK) package with a supplier device package of TO-252AA. It operates over a junction temperature range of -55°C to 175°C. The PowerTrench technology optimizes low gate charge and low RDS(on) for improved system efficiency.
