B540CX-13

Overview

The B540CX-13 is a trench Schottky barrier rectifier manufactured by Diodes Incorporated, housed in an SMC (DO-214AB) package. It features a peak repetitive reverse voltage of 40V and an average rectified output current of 5A. The maximum forward voltage drop is 0.52V at 5.0A and +25°C, while the maximum reverse leakage current is 0.3mA at 40V and +100°C. The device supports a non-repetitive peak forward surge current of 80A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

Utilizes trench Schottky barrier technology for low leakage current and soft, fast switching capability.
Capable of operating at a junction temperature up to +150°C.
Constructed with lead-free finish, RoHS compliant, and halogen/antimony free green compound.

Applications

SMPS
AC-DC converters
DC-DC converters
Freewheeling diodes
Reverse polarity protections

Procurement Notes

Verify the specific datasheet revision DS43592 Rev. 3 - 2 when sourcing components. Confirm that the ordering suffix '-13' corresponds to the 3,000-unit tape and reel carrier format. Ensure compliance with AEC-Q100/101 standards if automotive qualification is required, as standard production may differ from specific change-controlled automotive parts.

Selection Notes

Select this component for low-voltage, high-frequency applications requiring efficient rectification. The SMC package provides adequate thermal performance with a junction-to-ambient resistance of 50°C/W on standard FR-4 substrates. Consider derating the continuous current by 20% if used with capacitive loads to maintain reliability.

Part Context

This part belongs to the B540CX series of trench Schottky barrier rectifiers. It is designed as a surface-mount alternative to through-hole rectifiers, offering improved switching characteristics and lower power loss compared to standard silicon rectifiers.

Replacement Considerations

Direct substitutes include other 40V 5A SMC Schottky rectifiers such as the B540C-13 or B540C-13-F, provided they meet the same electrical specifications and package dimensions.
