Diode Arrays Procurement Notes

Verify the specific manufacturer source, as this component was originally produced by Fairchild Semiconductor. Confirm that the TO-247 package and pinout match your circuit requirements. Ensure the 45 V rating aligns with your system's peak inverse voltage needs. Check for updated datasheets if sourcing from third-party distributors to confirm current production status and quality standards.

Diode Arrays Selection Notes

Select this component when designing low-voltage, high-current power supplies requiring minimal conduction losses. The center-tap configuration is ideal for full-wave rectification without a bridge. Consider the thermal resistance of 1.2 °C/W for heat sink calculations. Ensure the operating junction temperature remains within the specified -65 to +150 °C range for reliable long-term operation.

Diode Arrays Part Context

This part belongs to the MBR40 series of 40 A Schottky Barrier Rectifiers, which includes variants with different reverse voltage ratings such as 35 V, 50 V, and 60 V. These devices are designed for general-purpose power rectification where efficiency and speed are critical. The series shares similar physical dimensions and electrical characteristics, differing primarily in breakdown voltage specifications.

Diode Arrays Replacement Considerations

Direct substitutes include MBR4035PT, MBR4050PT, and MBR4060PT from the same series, provided the voltage rating meets or exceeds the circuit requirements. Verify that replacement parts maintain the TO-247 package and center-tap configuration.
