B340CE-13 Equivalent & Substitute Parts

Part Overview

The B340CE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 40 V DC reverse voltage and 3 A average rectified current in a surface mount SMC (DO-214AB) package. This component is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory availability changes, or when specific manufacturer qualifications are required for particular applications.

Substitute Part Grouping Explanation

Substitution eligibility for the B340CE-13 is determined by the following core parameters: Voltage - DC Reverse (Vr) maximum of 40 V, Current - Average Rectified (Io) of 3 A, forward voltage of 500 mV maximum at 3 A, fast recovery speed characteristic (≤ 500ns, > 200mA), Schottky technology, surface mount mounting type, and operating temperature range of -55°C to 150°C. All substitute parts listed maintain these electrical specifications and package compatibility with DO-214AB (SMC) or equivalent surface mount configurations. Variations in secondary parameters such as reverse leakage current, capacitance, and specific manufacturer qualifications do not disqualify substitution when primary electrical ratings and physical package dimensions remain compatible.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and thermal compatibility with the B340CE-13 across the specified operating range. Selection between equivalent parts should be based on the following criteria:

Standard Industrial Applications: B340CE-13, 5822SMJE3/TR13, SK34-TP, and SK34_R1_00001 are suitable for general-purpose rectification applications where automotive qualification is not required.

Automotive Applications: B340Q-13-F, SK34-AU_R1_000A1, SS34HE3_B/H, and SS34HE3_B/I carry AEC-Q101 qualification and Automotive grade designation, meeting requirements for automotive circuit implementations.

Inventory and Availability: SK34_R1_00001 (Panjit International Inc.) maintains the highest inventory level at 53,300 pieces. B340Q-13-F (Diodes Incorporated) provides 18,040 pieces. Selection based on supply chain requirements and lead time considerations is valid when electrical specifications remain identical.

Manufacturer Preference: Direct manufacturer substitution within Diodes Incorporated product line (B340CE-13 to B340Q-13-F) maintains consistent design support and documentation.

Frequently Asked Questions (FAQ)

Q: Can SS34 (SMA package) substitute for B340CE-13 (SMC package)?

A: SS34 is a different package type (DO-214AC, SMA) compared to the B340CE-13 (DO-214AB, SMC). While electrical ratings are equivalent, physical package dimensions differ. Substitution requires PCB layout modification and is not a direct pin-compatible replacement.

Q: What is the difference between B340CE-13 and B340Q-13-F?

A: Both parts are manufactured by Diodes Incorporated with identical electrical specifications. B340Q-13-F includes Automotive grade designation and AEC-Q101 qualification, making it suitable for automotive applications. The B340CE-13 is suitable for general industrial applications.

Q: Are all SMC package variants (DO-214AB) directly interchangeable?

A: Yes. All substitute parts listed with DO-214AB package designation (SMC) are physically and electrically compatible with the B340CE-13 for direct PCB replacement without layout modification.

Q: What does AEC-Q101 qualification indicate?

A: AEC-Q101 is an automotive industry standard qualification for discrete semiconductors. Parts carrying this qualification (B340Q-13-F, SK34-AU_R1_000A1, SS34HE3_B/H, SS34HE3_B/I) meet automotive reliability and testing requirements and are suitable for automotive circuit applications.

Q: How do reverse leakage current variations affect substitution?

A: Reverse leakage current variations (200 µA to 1.5 mA at 40 V) among substitute parts do not affect substitution eligibility. All values remain within acceptable limits for Schottky rectifier operation. Selection based on leakage current is application-specific and does not disqualify any listed substitute.

Q: Is RoHS3 compliance consistent across all substitute parts?

A: Yes. All listed substitute parts maintain RoHS3 compliance status, ensuring compatibility with environmental and regulatory requirements.

Q: What packaging options are available for this 40 V, 3 A Schottky rectifier specification?

A: The primary package for this specification is DO-214AB (SMC). SS34 offers an alternative DO-214AC (SMA) package with identical electrical ratings but different physical dimensions, requiring PCB layout modification for substitution.
