SBR20A40CTFP-JT

Diode Arrays Overview

The SBR20A40CTFP-JT is a Super Barrier Rectifier diode manufactured by Diodes Incorporated, featuring a dual common cathode configuration in an ITO-220AB package. It provides a maximum average rectified output current of 20 A per leg and a peak repetitive reverse voltage rating of 40 V. The device utilizes patented SBR technology to achieve a low forward voltage drop, with typical values of 0.41 V at 10 A and 25°C, or 0.60 V at 20 A and 25°C. It supports an operating junction temperature range from -65°C to +150°C and offers high thermal stability.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm mechanical dimensions and packaging details. The JT suffix indicates an alternate ITO-220AB case style; ensure physical compatibility with existing board layouts before procurement. Confirm RoHS compliance status and environmental declarations directly with the supplier or manufacturer datasheet.

Diode Arrays Selection Notes

Select this component when low forward voltage drop and high-temperature reliability are critical requirements. The SBR technology offers better thermal stability than conventional Schottky diodes, reducing the risk of thermal runaway. Ensure the application voltage does not exceed the 40 V rating and that the thermal management system can handle the specified junction temperatures up to 150°C.

Diode Arrays Part Context

This part belongs to the SBR20A series of Super Barrier Rectifiers from Diodes Incorporated. The series combines the benefits of Schottky diodes (low VF) with the ruggedness of silicon PN junctions. The FP variant denotes the ITO-220AB package, while the base model SBR20A40CT represents the standard TO-220AB version.

Diode Arrays Replacement Considerations

SBR20A40CTFP-G serves as a direct alternative within the same product family, differing primarily in molding compound specifications.

Diode Arrays FAQ

What is the difference between the SBR20A40CTFP and SBR20A40CTFP-JT packages?

The SBR20A40CTFP-JT utilizes an alternate ITO-220AB case style with slightly different dimensional tolerances compared to the standard SBR20A40CTFP, though both share the same electrical characteristics.

How does SBR technology improve performance over standard Schottky diodes?

SBR technology provides superior avalanche capability and significantly reduced high-temperature reverse leakage current, enhancing reliability in high-temperature operations where standard Schottky diodes might fail due to thermal runaway.
