Why Choose the Mersen D078870 Medium Time-Lag Miniature Fuse?
The Mersen D078870, catalogue reference MI6SA50V0.2, is a compact semiconductor miniature fuse designed to protect sensitive electronic circuits and equipment against damaging overcurrents. Part of Mersen’s 6.3 × 32 mm SA fuse range, it combines dependable circuit protection with a medium time-lag characteristic that tolerates brief current surges without unnecessary operation.
Rated at 0.2 A and 500 V AC, the D078870 is particularly suitable for low-current electronic and semiconductor applications. Its SA operating characteristic allows short-duration inrush or transient currents to pass whilst still providing reliable protection against sustained overloads and fault conditions.
The compact 6.3 × 32 mm cylindrical format is designed for clip mounting within compatible fuse holders and equipment assemblies. With a very high breaking capacity, low clearing energy and dependable Mersen construction, the D078870 provides effective protection for industrial electronics, power supplies, control circuits and sensitive electrical equipment.

Reliable Protection for Circuits with Transient Currents
Electrical and electronic circuits can experience brief inrush currents during start-up, switching or capacitor charging. A fuse that operates too quickly may disconnect the circuit unnecessarily. The medium time-lag characteristic of the Mersen D078870 allows these temporary current peaks to pass whilst maintaining protection against sustained overloads and short circuits.
The fuse’s low clearing I²t limits the electrical energy released during fault interruption, helping protect sensitive electronic components. Its compact clip-mounted design also makes inspection and replacement straightforward when installed in an appropriately rated 6.3 × 32 mm fuse holder.
Typical Applications
- Semiconductor and electronic circuit protection.
- Industrial power supplies.
- Automation and control equipment.
- Circuits with inrush or transient current conditions.
- Power conversion and rectifier equipment.
- Instrumentation and monitoring systems.
- Low-current industrial electronic assemblies.
