Why Choose the Mersen L205906 High Speed Semiconductor Fuse?
The Mersen L205906 is a compact high speed semiconductor miniature fuse designed to protect sensitive electronic components and semiconductor devices against overcurrent and short-circuit faults. Part of the Mersen MI5FA 250 V axial-lead fuse series, it provides very fast fault interruption to help minimise damaging electrical and thermal energy.
Its FA high speed operating characteristic makes the fuse suitable for electronic circuits where conventional general-purpose fuses may not respond quickly enough to protect delicate semiconductor components. The axial wire leads enable direct integration into printed circuit boards and compact electronic assemblies.
With a rated current of 0.25 A, a rated voltage of 250 V AC and a standard 5 × 20 mm body, the Mersen L205906 provides precise protection for low-current applications. Its compact dimensions and direct-solder mounting help simplify installation within industrial electronics, control equipment and power supplies.

Fast Protection for Sensitive Electronic Components
Semiconductor devices can be damaged by excessive current within a very short period. The Mersen L205906 uses a very fast FA characteristic to interrupt electrical faults rapidly, helping reduce the let-through energy transferred to protected components.
Its axial lead construction allows the fuse to be soldered directly onto a printed circuit board, providing a compact and secure installation. This makes it particularly suitable for original equipment manufacturers, electronics engineers and industrial control system designers.
Typical Applications
- Semiconductor device protection.
- Printed circuit boards.
- Industrial electronic equipment.
- Power supplies and control circuits.
- Automation and process control equipment.
- Electronic measuring and instrumentation systems.
