Electronic switch e.g. n-channel MOSFET, for controlling e.g. windscreen wiper in automobile industry, has suppresser diode switchable parallel to switch to protect against over-voltage, where suppresser diode is integrated into housing

摘要

The switch (1) i.e. n-channel MOSFET (2), has an integrated switching circuit formed on a semiconductor substrate (10) and enclosed by a housing. A suppresser diode (7) is assigned to the switch and formed in a separate manner and switchable parallel to the switch to protect against over-voltage. The suppresser diode is integrated into the housing. A power input contact of the semiconductor substrate is attached to a cooling tab. A power contact of the suppresser diode and a power contact of the semiconductor substrate are directly attached to a pin by bonding wires.
