Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Confirm availability as distribution channels may vary. Ensure thermal management aligns with datasheet ratings for the intended operating environment.

Diode Arrays Selection Notes

Select this component when an isolated TO-220 variant is required for high-frequency rectification. The ITO-220AB package offers electrical isolation between the terminal and heatsink, simplifying mounting on grounded surfaces compared to standard TO-220AB configurations.

Diode Arrays Part Context

This part belongs to the MBR25xxCT and MBRF25xxCT series of dual common cathode Schottky rectifiers. The 'MBRF' prefix specifically denotes the ITO-220AB package variant, which distinguishes it from the non-isolated TO-220AB versions within the same electrical family.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRF2545CT-E3/45 (45 V rating) and MBRF2535CT-E3/45 (35 V rating). Verify that the replacement maintains the necessary voltage margin and thermal resistance requirements for the application.

Diode Arrays FAQ

What is the difference between the MBR25xxCT and MBRF25xxCT packages?

The MBRF25xxCT uses the ITO-220AB package, which provides electrical isolation between the terminal and the heatsink. The MBR25xxCT uses the standard TO-220AB package without this isolation feature.

Does the MBRF2560CTHE3/45 support solder bath reflow?

Yes, the device is rated for a maximum solder bath temperature of 275 °C for a duration of 10 seconds, per JESD 22-B106 standards.

What is the typical thermal resistance from junction to case?

For the MBRF25xxCT series, the typical thermal resistance from junction to case per diode is 4.5 °C/W.
