A particularly compact reflowable thermal switch is designed to provide thermal protection for power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, and SCRs. Due to their inherent self-reinforcing heat-producing behavior, these semiconductor devices can overheat and go into thermal runaway. The RTS is designed to protect against such overheating by reliably interrupting the circuit precisely […]
Six considerations for better circuit protection
In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]
Basics of ground fault interrupters
Ground-fault circuit interrupters (GFCIs) are sometimes also called earth leakage or residual-current circuit breakers. They can sense leakage current to earth ground and interrupt the circuit automatically when leakage current exceeds a predetermined value. A typical way of detecting ground fault currents is through the use of a core-balance protection device. Here hot (sometimes called […]
