The FQD8N80TM from onsemi is an 800V, 3.5A N-channel enhancement mode power MOSFET in a DPAK (TO-252) surface-mount package. The device is produced using onsemi proprietary planar stripe and DMOS technology, which has been especially tailored to reduce on-state resistance and provide superior switching performance with high avalanche energy strength. The 3.6 Ohm maximum RDS(on) at VGS=10V and 19nC typical total gate charge provide an excellent balance between conduction loss and switching loss for moderate-frequency power conversion applications. The low Crss of 8.6pF typical minimizes the Miller effect, reducing the risk of parasitic turn-on during high dV/dt switching transitions. The device is 100% avalanche tested, ensuring reliable operation under inductive load conditions where voltage spikes may exceed the rated VDS. The DPAK package provides surface-mount convenience with adequate thermal performance through the exposed drain tab, supporting up to 100W power dissipation when properly heatsinked. The FQD8N80TM is well-suited for off-line switch-mode power supplies, active PFC boost converters, and other high-voltage switching applications.

The FQD8N80TM is a vertical DMOS N-channel enhancement mode power MOSFET. (1) DMOS Structure: The planar stripe DMOS technology uses vertical current flow from source to drain through thousands of parallel MOSFET cells. Each cell has a gate oxide over the P-body region. When VGS exceeds the threshold (3.0-5.0V), an N-type inversion layer forms at the oxide-semiconductor interface, creating a conductive channel from source to drain. (2) Voltage Blocking: When VGS=0V, the P-body/N-drift junction blocks current flow. The 800V rating is achieved through a lightly-doped N-drift region that supports the high electric field during the off-state. (3) On-State Conduction: When the channel is formed, current flows from source through the channel, across the JFET region between adjacent P-bodies, through the N-drift region, and out the drain. The RDS(on) of 3.6 Ohm max includes the channel resistance, JFET resistance, drift region resistance, and substrate resistance. (4) Avalanche: When the drain voltage exceeds the breakdown voltage, the device enters avalanche mode. The current flows through the P-body/N-drift junction in breakdown. The 460mJ single-pulse avalanche energy rating indicates the device can absorb significant energy during inductive turn-off transients.
