SBL2050CT

Diode Arrays Overview

The SBL2050CT is a dual common-cathode Schottky barrier rectifier manufactured by Diodes Incorporated. It features a 50 V peak repetitive reverse voltage and supports an average rectified output current of 20 A at a case temperature of 95 °C. The device utilizes a TO-220AB package with three terminals, where Pin 1 and Pin 3 serve as anodes and Pin 2 is the common cathode. Key electrical characteristics include a forward voltage drop of 0.75 V at 10 A and a non-repetitive peak forward surge current capability of 250 A.

Diode Arrays Procurement Notes

Verify the specific part number against the official Diodes Incorporated datasheet DS23015 Rev. F-2 to confirm the 50 V rating and 20 A current capacity. Ensure the procurement matches the TO-220AB through-hole package configuration. Confirm compliance with UL flammability classification 94V-0 requirements for the plastic material used in the molded case.

Diode Arrays Selection Notes

Select this component for designs requiring low forward voltage drop and high switching efficiency in power conversion stages. Consider the thermal resistance junction-to-case value when designing heatsinking solutions to maintain the junction temperature within the specified operating range. Evaluate the derating curve for average forward current based on the expected case temperature during operation.

Diode Arrays Part Context

This component belongs to the SBL20xxCT series from Diodes Incorporated, which includes variants with reverse voltages ranging from 30 V to 60 V. All members of this family share the same 20 A current rating and TO-220AB physical footprint, differing primarily in their maximum repetitive reverse voltage specifications.

Diode Arrays Replacement Considerations

Compatible substitutes within the same series include SBL2030CT, SBL2035CT, SBL2040CT, SBL2045CT, and SBL2060CT, provided the circuit voltage requirements align with the specific reverse voltage ratings of each variant.

Diode Arrays FAQ

What is the pin configuration for the SBL2050CT?

Pin 1 and Pin 3 are the anodes, while Pin 2 serves as the common cathode.

What is the typical junction capacitance of the SBL2050CT?

The typical junction capacitance is 650 pF, measured at 1.0 MHz and an applied reverse voltage of 4.0 V DC.

How does the average forward current change with case temperature?
