FDB3860 Description

Short technical summary and product information.

FDB3860 is an N-Channel PowerTrench MOSFET from On Semiconductor (originally Fairchild Semiconductor), designed for low on-resistance and low gate charge. It is rated for 100V drain-to-source voltage, ±20V gate-to-source voltage, and continuous drain current of 30A at TC=25°C (6.4A at TA=25°C). The maximum drain-source on-resistance is 37mΩ at VGS=10V and ID=5.9A, with typical gate charge of 21nC and maximum total gate charge of 30nC.

Electrical characteristics include a gate threshold voltage of 2.5V min, 3.8V typ, and 4.5V max; input capacitance of 1310pF typical (1740pF max) at VDS=50V; and single-pulse avalanche energy of 96mJ. The part is 100% UIL tested according to the datasheet. Switching characteristics are specified at VDD=50V, ID=5.9A, VGS=10V with typical turn-on delay of 12ns, rise time 61ns, turn-off delay 17ns, and fall time 31ns.

Designed for switching applications, the FDB3860 is suited for DC-AC conversion and synchronous rectifier circuits. The PowerTrench process provides low rDS(on) and a low gate-charge figure of merit for efficient high-frequency switching. Thermal resistance is 1.75°C/W junction-to-case and 40°C/W junction-to-ambient, with operating junction temperature from -55°C to +150°C.

The device is RoHS compliant and offered in a TO-263AB (D2PAK) surface-mount package (TO-263-3). It is supplied on 330mm reels with 24mm tape width, 800 units per reel.
