SBR40150CTFP-G

Diode Arrays Overview

The SBR40150CTFP-G is a Super Barrier Rectifier diode manufactured by Diodes Incorporated, housed in an ITO-220AB (ITO-220FP-3) through-hole package. It features a dual common cathode configuration with two silicon elements. The device supports a peak repetitive reverse voltage of 150 V and provides a total average rectified output current of 40 A (20 A per leg). Electrical characteristics include a maximum forward voltage drop of 0.90 V at 20 A and 125°C, and a non-repetitive peak forward surge current rating of 280 A. The component operates within a temperature range of -65°C to +175°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and material composition. The '-G' suffix indicates a green molding compound variant that is halogen and antimony free. Confirm the package type matches the design requirements, as the base model may be available in different case styles such as TO-220AB. Ensure compliance with environmental regulations relevant to the target market before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when applications require high current handling capabilities combined with superior thermal performance compared to standard Schottky diodes. The dual common cathode configuration allows for efficient bridge-less PFC or full-wave rectification topologies. Consider the 175°C junction temperature rating for environments where heat dissipation is challenging. Evaluate the forward voltage characteristics at expected operating temperatures to ensure system efficiency targets are met.

Diode Arrays Part Context

This part belongs to the SBR40150 series from Diodes Incorporated, designed to replace traditional Schottky barriers in high-power applications. The SBR technology offers a compromise between the low forward voltage of Schottky diodes and the high-temperature reliability of PN junction rectifiers. The CTFP designation specifically identifies the ITO-220AB plastic package variant intended for board mounting with isolated heatsinking capabilities.

Diode Arrays Replacement Considerations

Direct replacements include the SBR40150CT for the standard TO-220AB package version. For equivalent electrical specifications in alternative packages, consult the manufacturer's cross-reference guide. Verify pinout compatibility and thermal resistance values when substituting into existing designs to maintain circuit integrity.

Diode Arrays FAQ

What is the isolation voltage specification for the ITO-220AB package?

The ITO-220AB package provides an isolation voltage of 2000 VAC from the terminal to the heatsink when tested for 3 seconds.
