Combined with a typical input capacitance (Ciss) of 95 pF at Vds = 100 V, the switching losses stay low even at frequencies above 100 kHz, which is where this part earns its keep in compact flyback designs. The 4.5 Ohm on-resistance is specified at Id = 1 A and Vgs = 10 V — at 2 A the Rds(on) will be higher due to the current-dependence of the channel, so budget conduction loss using the normalized curve from the datasheet. ## Thermal and temperature-grade envelope Operating junction temperature range spans -55°C to 150°C — the full industrial temperature grade. Maximum power dissipation is 45 W at Tc = 25°C, but the DPAK's thermal resistance to ambient (RthJA) is typically 80-100°C/W on a standard FR4 footprint, so the practical dissipation in still air is well below 2 W without a heatsink. The 150°C Tj(max) matches the upper limit for most automotive and industrial-grade components. ## Sourcing posture and compliance ROHS3 compliant per the latest EU directive.","metaTitle":"STD2N80K5 N-Channel MOSFET, 800V 2A DPAK, SuperMESH5","metaDescription":"STD2N80K5 N-channel 800V 2A MOSFET in DPAK.
