ABSTRACT:
A lead on chip (LOC) semiconductor device or a chip on lead (COL) semiconductor device with a protection circuit. Non-connection pins are made shorter than connection pins to reduce the inductance of the non-connection pins, or to obtain a different capability of the protection circuit for non-connection pins with respect to connection pins. The time constant of the protection circuit for the non-connection pins is made longer than that of the protection circuit for the connection pins. Further, the clamping capability for the connection pins is made greater than that for another connection pin adjacent to the connection pin.
