SBCT2045

Diode Arrays Overview

The SBCT2045 is a dual common cathode Schottky barrier rectifier manufactured by Diotec Semiconductor. It features two independent diodes within a single TO-220AB package, providing an average forward current of 10 A per diode at a case temperature of 100°C. The device supports a maximum repetitive peak reverse voltage of 45 V and withstands a peak forward surge current of 130 A (50 Hz) or 150 A (60 Hz). Key electrical characteristics include a maximum forward voltage of less than 0.55 V at 10 A and 25°C, with a typical junction capacitance of 500 pF.

Diode Arrays Procurement Notes

Verify the specific suffix against the official Diotec Semiconductor datasheet to confirm exact pinout and packaging variations. Ensure that the selected component meets the required thermal resistance specifications for your application's case temperature conditions. Cross-reference the manufacturer part number with authorized distributors to confirm availability and compliance with current RoHS standards before finalizing procurement.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a dual Schottky arrangement with a 45 V reverse voltage rating. The 10 A per diode rating makes it suitable for medium-power applications where low forward voltage is critical for efficiency. Consider the thermal resistance of 1.5 K/W when calculating heatsinking requirements to maintain the junction temperature within the specified -50°C to +150°C operating range.
