Title: Input protective circuit
Inventor: KAWABATA HIDEO
IPC: H01L27/06
Filed: 1987-02-17
Abstract: PURPOSE:To obtain sufficient positive surge protection effect with no enlarging voltage drop exceeding an allowable amount of a protected circuit by providing a transistor between a connection point of an input part with a protected circuit and a gland while making the transistor conductive at the time of impressing positive high voltage on the input part to suppress high voltage. CONSTITUTION:A transistor 6 to be made conductive when positive high voltage is impressed on the input part 3 is connected between a connection point of the input part 3 with a protected circuit 1. A current flows to the gland through this transistor 6 to suppress positive high voltage and the current flows to the gland from a protective diode 4 through a power supply line and an inside circuit so that the suppressed voltage is further clamped and suppressed. Since anode voltage of the protective diode 4 is sufficiently suppressed by a conducting transistor 6, the voltage drop does not exceed an allowable amount of the protected circuit 1. Thereby, sufficient positive surge protective effect can be obtained not depending on impedance between the power supply line and the gland.
