BSP78HUMA1 Description

Short technical summary and product information.

The Infineon Technologies BSP78HUMA1 is a versatile N-channel vertical power FET belonging to the HITFET family, utilizing Smart SIPMOS technology. It is designed for 12V DC applications and serves as a µC-compatible power switch, capable of handling resistive, inductive, and capacitive loads in switching or linear circuits. This device replaces electromechanical relays and discrete circuits, offering enhanced protection features.

 

Key electrical specifications include a drain source voltage (VDS) of 42V and a nominal load current (ID(Nom)) of 3A. The on-state resistance (RDS(on)) is typically 35mOhm. The device operates within a temperature range of -40°C to 150°C (TJ).

 

Integrated protection functions are a core feature, including overload protection, short circuit protection, overvoltage protection, current limitation, and thermal shutdown with auto-restart. It also provides input protection (ESD) and supports logic-level input. The BSP78HUMA1 is supplied in a PG-SOT223-4 package, which is surface-mounted.

 

This smart power switch is suitable for various automotive and industrial applications requiring reliable power control and protection. Its compact size and integrated features make it an efficient solution for replacing traditional relay and discrete circuit designs.
