The Littelfuse PSR series with square housing is the perfect choice for power semiconductors. This series has been specially developed for the protection of power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFET and other semiconductor elements, which are commonly used for power converter and processing accessories.
Drives with variable frequencies, inverters, UPS, rectifiers and soft starters use e.g. this type of power semiconductor components. Littelfuse’s PSR series provides the optimized, extremely fast circuit protection required for modern power converters. These products are typically used in a variety of applications such as the pulp and paper industry, cranes and heavy duty accessories, manufacturing, wastewater treatment plants, and many large factories and MRO facilities.
