FFSH20120A

Single Diodes Overview

The onsemi FFSH20120A is a high-voltage Schottky rectifier designed for power conversion applications. It features a peak repetitive reverse voltage of 1200V and a maximum average forward rectified current of 20A per leg in its dual common cathode configuration. The device utilizes a Fast Recovery Soft-Hybrid technology to optimize switching performance, resulting in low reverse recovery charge and minimal reverse recovery current overshoot. Housed in a D2PAK-3 surface-mount package, it offers robust thermal management capabilities suitable for demanding industrial environments.

Single Diodes Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS directives if required by your region. Cross-reference the part number with official distributor catalogs to confirm active status and availability before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when high voltage blocking capability and moderate current handling are required in a compact surface-mount form factor. The soft-recovery feature makes it suitable for circuits sensitive to voltage spikes and noise. Compare thermal resistance values against your heatsinking strategy to ensure reliable operation under continuous load conditions.

Single Diodes Part Context

This device belongs to onsemi's Fast Recovery Soft-Hybrid (FFSH) series, which combines the benefits of Schottky diodes with improved reverse recovery characteristics. The series targets applications requiring reduced switching losses and lower electromagnetic interference compared to standard fast recovery diodes, offering a balanced solution for modern power electronics designs.

Single Diodes Replacement Considerations

Consult the official cross-reference list for verified substitutes. Ensure any replacement matches the 1200V rating, 20A current capacity, and D2PAK-3 package dimensions. Verify that alternative devices maintain similar soft-recovery characteristics to preserve circuit stability and electromagnetic compatibility.
