Why Choose the Mersen D208153 High-Speed Semiconductor Fuse?
The Mersen D208153 is a compact high-speed semiconductor protection fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. Also identified by the catalogue number MI6FAP25V2, it provides very fast fault interruption for semiconductor-based circuits and industrial electronic equipment.
With a rated current of 2 A and a rated voltage of 250 V AC, the D208153 helps reduce the thermal and electrical stress placed on diodes, thyristors, triacs and other sensitive components. Its low melting and clearing I²t values help limit the energy passing through the protected circuit during a fault.
The fuse features a compact 6.3 × 32 mm ceramic body with axial leads for direct soldering onto printed circuit boards. This space-saving construction makes it suitable for converters, power supplies, automation equipment and other electronic assemblies requiring reliable PCB-mounted protection.
