ST6045C

Diode Arrays Overview

The ST6045C is a dual common cathode Schottky rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 45 V and an average forward current rating of 30 A per leg. The device utilizes a TO-220-3 through-hole package, specifically the TO-220AB configuration. Key electrical parameters include a maximum DC reverse voltage of 45 V and a forward voltage of approximately 580 mV at 20 A. The component operates within a junction temperature range of -55°C to 150°C and exhibits a maximum reverse leakage current of 3 mA at 45 V.

Diode Arrays Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format such as tube or tape-and-reel configurations. Confirm that the procurement channel sources directly from authorized distributors to ensure authenticity. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the TO-220-3 package dimensions match the target PCB footprint constraints before finalizing the supply chain agreement.

Diode Arrays Selection Notes

Select this component for low-voltage, high-current applications requiring fast recovery characteristics. The 45 V rating suits systems with moderate voltage spikes. Compare thermal performance against similar TO-220 devices if heat dissipation is critical. Consider the 30 A current rating relative to the expected load profile and derating factors. Evaluate the cost-performance balance against alternative Schottky rectifiers in the same voltage class.

Diode Arrays Part Context

This part belongs to the ST(B.F)4045 series of ultra-low VF Schottky rectifiers from SMC Diode Solutions. It shares architectural similarities with surface mount variants like the STB4045C but offers through-hole mounting flexibility. The series is designed for efficiency in power conversion stages where conduction losses must be minimized. It complements other products in the portfolio by providing a rugged, leaded option for industrial and consumer power electronics.

Diode Arrays Replacement Considerations

Direct substitutes include the STB4045C for surface mount implementations and the ST2045C for lower current through-hole needs. Verify pinout compatibility and thermal pad connections when swapping packages. Ensure the replacement maintains the 45 V reverse voltage and sufficient current handling capabilities for the specific circuit application.
