Why Choose the Mersen P205035 Fast-Acting Semiconductor Miniature Fuse?
The Mersen P205035, catalogue reference MI5FCP25V0.5, is a compact 5 × 20 mm fast-acting semiconductor miniature fuse designed to protect sensitive electronic components against overcurrent and short-circuit conditions. Its FC fast-acting characteristic provides rapid fault interruption, helping to reduce the electrical and thermal energy passed to vulnerable semiconductor devices.
Rated at 0.5 A and 250 V AC, the P205035 provides dependable low-current protection for printed circuit boards, converters, power electronics and industrial control equipment. Its ceramic body supports effective arc containment, while its 1.5 kA minimum interrupting rating enables reliable disconnection during fault conditions.
The fuse is supplied with axial leads, allowing it to be soldered directly onto printed circuit boards or connected within electronic assemblies. This mounting arrangement makes the Mersen P205035 particularly suitable for OEM equipment, compact power supplies, instrumentation and automation products where a secure, permanent fuse connection is required.

Fast Protection for PCB-Mounted Electronics
Fast-acting semiconductor fuses interrupt excessive current quickly to help prevent thermal damage to sensitive electronic components. Their rapid response makes them suitable for converters, diodes, thyristors, triacs and other devices that may be damaged by the energy passed through a slower general-purpose fuse.
The Mersen P205035 combines fast-acting protection with axial lead mounting, allowing the fuse to be integrated directly into printed circuit board designs. This provides a compact and secure protection solution for electronic equipment where space, reliability and consistent fault interruption are important.
Typical Applications
- Printed circuit boards.
- Semiconductor device protection.
- Converters and rectifier circuits.
- Diodes, thyristors and triacs.
- Electronic power supplies.
- Industrial automation equipment.
