That means the 6 A rating is only usable with a substantial heatsink and at case temperatures well below 25°C; the practical continuous current in a typical TO-220FP layout is lower, governed by the junction-to-case thermal impedance and the ambient temperature.","metaTitle":"STF6N90K5 N-Channel MOSFET, 900 V, 6 A, TO-220FP","metaDescription":"STF6N90K5 N-channel 900 V 6 A MOSFET in TO-220FP.
