N-Channel Tape & Reel (TR) 1.4 Ω @ 425mA, 10V ±30V 220pF @ 25V 6.5nC @ 10V 200V TO-261-4, TO-261AA
FQT4N20TF Overview
This type of breakdown is known as "avalanche breakdown", and the energy applied to the MOSFET is called avalanche energy, and the avalanche energy rating (Eas) is 52 mJ.The maximum input capacitance of this device is 220pF @ 25V, because the input capacitance of an op amp is defined as the difference between the input terminals with one input grounded.As shown in the table below, the drain current of this device is 0.85A.There is no pulsed drain current maximum for this device based on its rated peak drain current 3.4A.To maintain normal operation, it's recommended that the DS breakdown voltage be kept above 200V.The drain-to-source voltage (Vdss) of this transistor needs to be at 200V in order to operate.Using drive voltage (10V), this device helps reduce its power consumption.
FQT4N20TF Features
the avalanche energy rating (Eas) is 52 mJ
based on its rated peak drain current 3.4A.
a 200V drain to source voltage (Vdss)
