This is a chassis-mount device — the ISOTOP baseplate bolts directly to a heatsink or panel, carrying the thermal path through the mounting surface rather than a PCB. ## On-resistance and gate drive Maximum on-resistance is 90 mOhm at 26 A drain current with 12 V gate drive. The gate threshold voltage is 4 V at 2.5 mA, so a 10 V to 12 V gate signal is needed to fully enhance the channel and stay below the ±30 V Vgs absolute maximum. ## Thermal and power capability Rated for 568 W power dissipation and a junction temperature range of -55°C to 150°C. The wide temperature grade suits applications where the heatsink sees ambient extremes — industrial drives, welding equipment, or high-current DC-DC converters in sealed enclosures.","metaTitle":"APL502J MOSFET N-Ch 500V 52A ISOTOP, Chassis Mount","metaDescription":"APL502J N-Channel MOSFET, 500V, 52A, 568W, ISOTOP chassis mount.
