RY7P250BM is a 100V device nominally rated at 300A and comes in an 8 x 8mm DFN8080 package.
“In hot-swap circuits used to safely replace modules while servers remain powered on, mosfets are required that offer both wide safe operating area and low on-resistance to protect against inrush current and overloads,” according to the company.
At switch-on, the device is rated for 16A from 48V for 10ms, or 50A from 48V for 1ms, “enabling support for load conditions conventional mosfets struggle to handle, it said.
To minimise constant dissipation during normal operation, maximum on-resistance is 1.86mΩ (10Vg, 50A drain, 25°C junction).
Total gate charge, which is less important away from dc-dc converters, is between 105 and 240nC (50V, 50A 10Vg).

Earlier this year, the same company announced a 5 x 6mm DFN 30V mosfet for hot-swap controllers.
