Key Parameters

Substitute Part Grouping Explanation

Substitution of the B540CE-13 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 5 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Equivalence Criteria:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance Criteria:

• RoHS Status: ROHS3 Compliant

The B540C-13-F meets all electrical and mechanical requirements for direct substitution. Both parts share the same base product number (B540), voltage rating, current rating, forward voltage specification, recovery speed classification, and package configuration. The substitute part maintains full RoHS3 compliance and is currently in Active product status with established supply availability.

Parameter Comparison

Engineering Selection Recommendations

The B540C-13-F is the direct substitute for the obsolete B540CE-13. Both parts are manufactured by Diodes Incorporated and share identical electrical ratings, forward voltage characteristics, recovery speed classification, and package configuration. The substitute part is currently in Active product status, ensuring long-term availability and supply chain continuity.

The B540C-13-F maintains ROHS3 compliance and is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements. The reverse leakage current specification of the substitute (500 µA @ 40 V) is higher than the main part (200 µA @ 40 V), and the capacitance specification is lower (300 pF versus 340 pF @ 4V, 1MHz). Both variations remain within acceptable operating parameters for Schottky rectifier diode applications and do not impact functional equivalence for standard rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can the B540C-13-F be used as a direct replacement for the B540CE-13 in existing designs?

A: Yes. The B540C-13-F is electrically and mechanically equivalent to the B540CE-13. Both parts have identical voltage ratings (40 V), current ratings (5 A), forward voltage specifications (550 mV @ 5 A), recovery speed classifications (Fast Recovery ≤ 500ns), and package configurations (DO-214AB, SMC Surface Mount). The substitute part is suitable for direct board-level replacement without circuit modification.

Q: What are the differences between the B540CE-13 and B540C-13-F?

A: The primary differences are product status and secondary electrical parameters. The B540CE-13 is Obsolete, while the B540C-13-F is Active. The reverse leakage current of the B540C-13-F is 500 µA @ 40 V compared to 200 µA @ 40 V for the main part. The capacitance of the B540C-13-F is 300 pF @ 4V, 1MHz compared to 340 pF @ 4V, 1MHz for the main part. These secondary parameter variations do not affect functional equivalence in rectification applications.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AB SMC Surface Mount package. The B540C-13-F is available in Cut Tape (CT) and Digi-Reel® packaging formats, while the B540CE-13 packaging format is not specified in the available data. The physical package dimensions and PCB footprint are identical.

Q: Is the B540C-13-F RoHS compliant?

A: Yes. The B540C-13-F is ROHS3 Compliant, matching the compliance status of the B540CE-13. Both parts meet RoHS3 requirements for hazardous substance restrictions.

Q: What is the operating temperature range for the B540C-13-F?

A: The B540C-13-F operates across a junction temperature range of -55°C to 150°C. The operating temperature range for the B540CE-13 is not specified in the available data.

Q: Why is the B540CE-13 listed as Obsolete?

A: The B540CE-13 has been discontinued by Diodes Incorporated. The B540C-13-F is the active equivalent part that replaces it in the manufacturer's product line. The B540C-13-F provides identical electrical and mechanical specifications with established supply availability.
