FFSH15120ADN-F155

Diode Arrays Overview

The FFSH15120ADN-F155 is a Silicon Carbide (SiC) Schottky diode manufactured by onsemi, formerly Fairchild Semiconductor. It features a dual anode common cathode configuration housed in a TO-247-3 package for through-hole mounting. The device supports a repetitive reverse voltage of 1.2 kV and conducts a forward current of 15 A. Key electrical parameters include a maximum forward voltage of 1.45 V, a peak surge current of 80 A, and a reverse leakage current of 200 uA. It operates within a temperature range of -55°C to +175°C with a power dissipation rating of 110 W.

Diode Arrays Procurement Notes

Verify the manufacturer designation carefully, as onsemi acquired Fairchild Semiconductor's semiconductor business. Confirm the specific suffix F155 matches the required lead time and packaging specifications. Ensure the TO-247-3 package footprint aligns with the target PCB design. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with the design requirements.

Diode Arrays Selection Notes

Select this component when a dual-diode configuration is required in a single package to save board space. The 1.2 kV rating makes it suitable for 600V and 800V bus systems. Consider the 15 A continuous current rating against the thermal management capabilities of the final assembly. The SiC technology offers advantages in efficiency at higher switching frequencies compared to standard silicon alternatives.

Diode Arrays Part Context

This part belongs to the EliteSiC series from onsemi, representing third-generation wide bandgap semiconductor technology. The FFSH15120ADN series specifically targets high-efficiency power conversion applications. The transition from Fairchild to onsemi branding reflects corporate acquisition history, but the technical specifications and manufacturing standards remain defined by the current product documentation.

Diode Arrays Replacement Considerations

Direct substitutes may include other 1200V SiC Schottky diodes in TO-247-3 packages with similar current ratings. Verify pinout compatibility for dual anode common cathode configurations. Check if alternative manufacturers offer equivalent thermal resistance and forward voltage characteristics for seamless integration.
