Load-dump modules are specialized electronic components designed to protect automotive and industrial systems from voltage spikes, particularly in vehicles with alternators. These modules are produced by various manufacturers globally, including companies like Infineon Technologies (Germany), STMicroelectronics (Switzerland), and Texas Instruments (USA). They serve the automotive and heavy equipment industries, ensuring reliable operation by mitigating load-dump transients—a common issue in 12V/24V electrical systems. Key products include surge protection diodes, voltage regulators, and integrated load-dump protection ICs, widely used in engine control units (ECUs), lighting systems, and battery management.
