STMicroelectronics no longer manufactures this device in volume, and there is no official last-time-buy window remaining. ## Gate drive and switching — what the 10 V spec tells you The STP8NM60ND is specified with a drive voltage of 10 V for the rated on-resistance. The 700 mOhm Rds(on) is measured at 3.5 A with 10 V on the gate. The total gate charge is 22 nC at 10 V, and input capacitance is 560 pF at 50 V Vds, so the switching losses are moderate; a typical gate drive IC with a few hundred mA peak current will turn this device on and off fast enough for a 50-100 kHz switching frequency in a PFC or flyback stage. ## Thermal — 70 W dissipation in a TO-220 In practice, a TO-220 without a heatsink will not handle more than a few watts continuous — the tab must be bolted to a heatsink or the PCB copper area for any real power. If your design runs the device near its current limit, the junction temperature rise needs to be calculated from the Rds(on) at operating temperature, not the 25 °C table value.","metaTitle":"STP8NM60ND N-Channel MOSFET, 600 V, 7 A, TO-220","metaDescription":"STP8NM60ND N-channel 600 V 7 A MOSFET in TO-220.
