FDT3612 Description

Short technical summary and product information.

The FDT3612 is an N-Channel PowerTrench MOSFET designed by On Semiconductor for efficient DC/DC converter applications. It is rated for a drain-source voltage of 100V and a continuous drain current of 3.7A at 25°C ambient temperature. The device offers a maximum on-resistance of 120mOhm at a 10V gate drive and 130mOhm at 6V, enabling low conduction losses. With a typical gate charge of 14nC, the FDT3612 supports fast switching speeds, making it suitable for high-frequency power management circuits.

 

The MOSFET is packaged in a Pb-free SOT-223-4 surface-mount package (TO-261-4), which provides good thermal performance with a junction-to-ambient thermal resistance of 42°C/W. It is capable of handling pulsed drain currents up to 20A and has an avalanche energy rating of 90mJ. The device operates over a junction temperature range of -55°C to 150°C.

 

Applications include DC/DC converters and power management in various electronic systems. The low gate charge and fast switching characteristics make it ideal for synchronous and conventional PWM controller designs.
