FDI3632 Description

Short technical summary and product information.

The FDI3632 is an N-Channel PowerTrench MOSFET designed for high-efficiency power conversion and automotive applications. It offers a drain-source breakdown voltage of 100V and a continuous drain current of 80A at case temperature 111°C (12A at ambient 25°C). The device features a typical on-resistance of 7.5mOhm and maximum of 9mOhm at VGS = 10V, enabling low conduction losses.

 

This MOSFET is qualified to AEC-Q101, meeting the rigorous reliability standards of the automotive industry. It incorporates low Miller charge and low Qrr body diode for improved switching performance. The device is capable of handling single pulse avalanche energy up to 393mJ, making it robust for harsh environments.

 

The FDI3632 is housed in a through-hole TO-262-3 (I2PAK) package, suitable for PCB mounting with excellent thermal dissipation. Thermal resistance junction-to-case is 0.48°C/W and junction-to-ambient is 62°C/W for the TO-262 package. Operating temperature range is -55°C to 175°C.

 

Typical applications include DC/DC converters, off-line UPS, primary switches for 24V and 48V systems, high voltage synchronous rectifiers, and automotive systems such as direct injection and electronic valve train control.
