Why Choose the Mersen D208038 High-Speed Semiconductor Fuse?
The Mersen D208038 is a compact high-speed semiconductor protection fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. Identified by the Mersen catalogue number MI6FAP69V2, it combines a very fast-acting fuse characteristic with a miniature cartridge format suitable for modern electronic equipment.
With a rated current of 2 A and a rated voltage of 690 V AC, the D208038 is engineered for applications where rapid fault interruption is essential. Its low let-through energy helps reduce the electrical and thermal stress placed on semiconductor devices during fault conditions.
The fuse features a compact 6.3 × 32 mm body with axial leads, enabling direct soldering onto printed circuit boards or integration into dedicated electronic assemblies. This construction makes it particularly suitable for industrial controls, power conversion equipment and other systems requiring dependable PCB-mounted protection.

- Industrial electronic control equipment.
- Power conversion circuits.
- Semiconductor protection assemblies.
- Variable speed drive control circuits.
- Industrial power supplies.
- Inverters and converter equipment.
- Printed circuit board assemblies.
