摘要： A loudspeaker protective unit for protecting a loudspeaker device against an excessive input current includes a lamp connected in series with the loudspeaker unit. The lamp is housed in a casing exhibiting light-sealing properties formed of an electrically conductive material, and is sealed with a sealant exhibiting a predetermined electrical conductivity. The spacing between lead lines of the lamp housed in the casing is of a preset value. An inert gas is sealed within a main lamp body unit and a preset voltage is applied to the main lamp body unit. When the voltage is applied across the lead lines, an electrical discharge is produced to interrupt the current flowing through the filament so as to prohibit a temperature rise in the lamp.

摘要： Latch-up of each of parasitic thyristors (T1-T4), which occurs when a circuit element (B1) is formed on a semiconductor substrate in which an IGBT (Z1) has been formed, is prevented by a circuit for preventing the latch-up using Schottky barrier diodes (D2, D3) formed on the semiconductor substrate. Each of the Schottky barrier diodes (D2, D3), which is composed of a junction between a diffused layer used for forming the circuit element and a metal wiring layer, is used in the circuit for preventing the latch-up action of each of the parasitic thyristors (T1-T4). Thereby, the area of the semiconductor device can be made smaller while the semiconductor device can have a higher protection effect.
