SBCT1045

Diode Arrays Overview

The SBCT1045 is a Schottky Barrier Rectifier Diode manufactured by Diotec Semiconductor. It features a dual common cathode configuration with a total average forward current (IFAV) of 10A, split as 2 x 5A per diode. The device has a maximum repetitive peak reverse voltage (VRRM) of 45V. Forward voltage characteristics are specified at less than 0.55V at 5A and less than 0.63V at 10A, both measured at a junction temperature of 25°C. The typical junction capacitance is 300pF at zero bias. The component supports a peak forward surge current of 100A for half-sine waves at 50Hz and 120A at 60Hz. It operates within a junction temperature range of -50°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific part number suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the procurement channel provides genuine components directly from Diotec Semiconductor or authorized distributors. Check for any recent product change notifications regarding package dimensions or electrical parameters before finalizing orders.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or polarity protection in low-voltage applications. Ensure the operating junction temperature does not exceed 150°C and that the thermal resistance allows for adequate heat dissipation at the expected load currents. Verify that the 45V reverse voltage rating provides sufficient margin for the circuit's peak inverse voltage.

Diode Arrays Part Context

The SBCT1045 belongs to the SBCT10xx series of Schottky Barrier Rectifiers from Diotec Semiconductor. This series includes various voltage ratings ranging from 20V to 100V, all sharing the same 10A total current capacity and dual common cathode package. The series is designed for general commercial and industrial applications requiring efficient rectification.

Diode Arrays Replacement Considerations

Other parts in the SBCT10xx series may serve as substitutes if voltage ratings align. Cross-reference with other manufacturers' dual common cathode Schottky diodes having equivalent current and voltage ratings. Ensure pinout compatibility and thermal characteristics match the original design requirements.
