700 V, 8.6 A N-channel SuperMESH MOSFET in TO-220
The TO-220 through-hole package suits single-sided boards or assemblies where a heatsink mounts directly to the tab.
Any replacement evaluation should start with the same SuperMESH family at the same voltage and current class, but pin compatibility and gate-drive requirements must be verified against the target circuit.
Key ratings for the power-stage decision
The 700 V Vdss gives headroom for universal-input off-line converters (up to 400 V DC bus) with derating for leakage inductance spikes. The 8.6 A continuous rating at 25°C case temperature derates with case temperature — the actual current limit at elevated junction temperature is lower, so the thermal design must budget for the 150 W maximum power dissipation. Gate charge of 90 nC at 10 V is moderate; the driver must supply that charge per switching cycle, which influences gate-drive power and switching speed. Input capacitance of 2000 pF at 25 V drain-source is a typical figure for this die size and does not by itself limit switching frequency, but the combination of Qg and Ciss sets the driver's peak current requirement.
