It handles loads up to 18V and requires no Vcc supply — the gate is driven directly by the logic-level input. Built-in fault protection includes fixed current limiting and over-temperature shutdown, making it suitable for driving inductive loads like solenoids, relays, motors, and lamps in harsh environments such as automotive under-hood or industrial machinery.
At 35A continuous, a 4.5 mOhm typical Rds(on) means conduction losses of roughly 5.5 W at full load — manageable with the through-hole package bolted to a heatsink. The low on-resistance keeps the junction temperature rise under control even in the -40°C to 150°C operating range.
Package and mounting — TO-273AA (SUPER-220)
The IPS0551T comes in a through-hole TO-273AA package, also called SUPER-220. This is a large tabbed package designed for heatsink mounting — the metal tab is the drain connection and must be electrically isolated or connected to the appropriate rail.
