Junction Box

Automotive junction boxes come in two types: those using mechanical relays and those using MOSFETs as semiconductor relays.
To meet the needs of mechanical-relay drive applications, Toshiba has developed the SSM3K337R, a MOSFET in a small package (with 85% of the mounting area of the predecessor) that has active clamping circuitry for inductive loads. Toshiba also offers power MOSFETs in DPAK+ and TO-220SM (W) packages suitable for semiconductor relay applications.
