FMX-22S

Diode Arrays Overview

The FMX-22S is a silicon rectifier diode manufactured by Sanken Electric. It features a maximum repetitive reverse voltage (VRM) of 200 V and an average forward current (IF(AV)) rating of 10 A. The device exhibits a maximum forward voltage drop (VF) of 0.98 V and a maximum reverse recovery time (trr) of 30 ns, achieved through optimized lifetime control. The component is housed in a bare lead frame package that is Pb-free and RoHS compliant, with flammability equivalent to UL94V-0.

Diode Arrays Feature Summary

• Ultra-fast recovery characteristics enabled by optimized lifetime control technology
• Lead-free construction compliant with RoHS directives
• High thermal stability with UL94V-0 flammability rating

Diode Arrays Applications

• Secondary-side rectification in flyback converters
• Secondary-side rectification in LLC converters
• Freewheeling diodes in offline buck converters
• Freewheeling diodes in offline buck-boost converters

Diode Arrays Procurement Notes

Verify the specific datasheet version when sourcing, as documentation may vary slightly between distributors. Confirm that the received components match the bare lead frame form factor described in the official specifications. Ensure compliance requirements such as RoHS and UL94V-0 are explicitly stated in the supplier's certificate of conformity to guarantee material integrity and safety standards.

Diode Arrays Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge. The 200 V rating suits low-voltage secondary circuits, while the 10 A current capacity supports moderate power levels. Consider the bare lead frame for direct mounting or specialized thermal management solutions rather than standard plastic packages.

Diode Arrays Part Context

This ultra-fast recovery rectifier diode belongs to Sanken Electric's high-performance discrete semiconductor lineup. It is engineered specifically for modern switch-mode power supplies where efficiency and speed are critical. The design focuses on minimizing switching losses in high-frequency converter topologies commonly found in consumer and industrial power adapters.

Diode Arrays Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify that any replacement maintains the 200 V VRM, 10 A IF(AV), and sub-50 ns trr specifications to ensure circuit compatibility without redesign.
