Why Choose the Mersen Z093287 Miniature Semiconductor Fuse?
The Mersen Z093287 is a compact 6.3 × 32 mm high-speed semiconductor fuse designed to provide rapid protection for sensitive electronic components and power-semiconductor devices. Also identified by catalogue number MI6FA69V0.63, it has a rated current of 0.63 A and a rated voltage of 690 V AC.
Part of the Mersen FA 690 V miniature semiconductor fuse series, the Z093287 features a very fast-acting operating characteristic. This enables the fuse to interrupt damaging fault currents rapidly, helping reduce the thermal and electrical energy transferred to diodes, thyristors, triacs, rectifiers and other sensitive semiconductor components.
The fuse is manufactured in a durable ceramic cartridge format with ferrule terminals for clip mounting in compatible fuse holders. Its compact dimensions, low let-through energy and 30 kA minimum breaking capacity make it suitable for converters, industrial power electronics, automation equipment and OEM assemblies.

High-Speed Protection for Sensitive Electronic Components
Semiconductor components can be permanently damaged when excessive fault energy passes through a circuit. Very fast-acting fuses interrupt abnormal currents rapidly, helping limit peak current, thermal stress and the total electrical energy transferred to sensitive devices.
The Mersen Z093287 combines a high voltage rating with compact cartridge construction and low let-through energy. When correctly selected and coordinated with the protected circuit, it helps improve equipment reliability and reduce damage during overload and short-circuit conditions.
Typical Applications
- Semiconductor converter protection.
- Diode, thyristor and triac circuits.
- Industrial power supplies and rectifiers.
- Power-electronic control equipment.
- Automation and instrumentation systems.
- OEM electrical and electronic assemblies.
