FDMC8321L Description

Short technical summary and product information.

The FDMC8321L is an N-Channel PowerTrench MOSFET manufactured by onsemi. It is rated for a drain-to-source voltage of 40 V and a maximum continuous drain current of 49 A at TC=25°C (22 A at TA=25°C). Pulsed drain current is rated at 100 A. The device features a low maximum on-resistance of 2.5 mΩ at VGS=10 V, ID=22 A, and 4.1 mΩ at VGS=4.5 V, ID=18 A.

 

The FDMC8321L is optimized for DC-DC converters using synchronous or conventional PWM controllers. Its low gate charge (61 nC at VGS=10 V) and low input capacitance (3900 pF at VDS=20 V) help minimize switching losses and ringing. The next-generation enhanced body diode provides soft reverse recovery, and the 100% UIL tested design guarantees avalanche ruggedness with a single pulse avalanche energy of 86 mJ.

 

The device is supplied in an 8-PowerTDFN surface mount package (Power33) and operates over a junction temperature range of -55°C to 150°C. Maximum power dissipation is 40 W at TC=25°C (2.3 W at TA=25°C). The FDMC8321L is Pb-Free, Halide Free, and RoHS compliant.
