B340BE-13 Equivalent & Substitute Parts

Part Overview

The B340BE-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 SMB (DO-214AA) package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing design and procurement requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B340BE-13 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C ~ 150°C
• Technology: Schottky

All identified substitute parts meet these mandatory electrical and mechanical parameters. Variations in secondary parameters such as reverse leakage current and junction capacitance do not preclude substitution when primary ratings are identical.

Engineering Selection Recommendations

B340B-13-F (Diodes Incorporated)

The B340B-13-F is an active product from the original manufacturer with automotive-grade qualification (AEC-Q101) and highest inventory availability (95,300 pcs). This part is recommended as the primary substitute for applications requiring continued support from Diodes Incorporated. The automotive qualification provides additional process and reliability assurance.

B340BQ-13-F (Diodes Incorporated)

The B340BQ-13-F is an active automotive-qualified alternative from Diodes Incorporated with AEC-Q101 certification. Inventory availability is 35,300 pcs. This part is functionally equivalent to B340B-13-F and serves as a secondary option within the Diodes Incorporated product line.

SK34B-LTP (Micro Commercial Co)

The SK34B-LTP is an active product from Micro Commercial Co with the highest inventory level (146,400 pcs) and Tape & Reel packaging. This part is suitable for applications where multi-source qualification is required or where Micro Commercial Co supply chain integration is preferred.

SR34_R1_00001 (Panjit International Inc.)

The SR34_R1_00001 is an active product from Panjit International Inc. with inventory of 20,300 pcs. This part provides a third-source alternative for supply chain diversification and is suitable for applications requiring multiple qualified suppliers.

All substitute parts are RoHS3 compliant and REACH unaffected (except B340B-13-F and B340BQ-13-F which are REACH affected). Selection should be based on supply chain requirements, qualification standards, and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can B340B-13-F directly replace B340BE-13 in existing designs?

A: Yes. The B340B-13-F meets all mandatory electrical parameters (40 V, 3 A, 500 mV forward voltage, fast recovery speed) and uses the identical DO-214AA SMB package. The primary difference is product status (active vs. obsolete) and automotive qualification.

Q: What is the difference between B340B-13-F and B340BQ-13-F?

A: Both parts are manufactured by Diodes Incorporated and are electrically equivalent with identical ratings. Both carry AEC-Q101 automotive qualification. The primary distinction is inventory availability and packaging format (Cut Tape & Digi-Reel for both).

Q: Are there differences in reverse leakage current between substitute parts?

A: Yes. The B340BE-13 specifies 200 µA @ 40 V reverse leakage, while B340B-13-F, B340BQ-13-F, and SK34B-LTP specify 500 µA @ 40 V. The SR34_R1_00001 specifies 200 µA @ 40 V, matching the original part. These variations are within acceptable limits for Schottky diode applications and do not affect substitution eligibility.

Q: Does packaging format affect substitution?

A: No. All substitute parts use the DO-214AA SMB surface mount package. Packaging format variations (Cut Tape & Digi-Reel vs. Tape & Reel) relate to supply and handling only and do not affect electrical or mechanical compatibility on the PCB.

Q: Which substitute part should be selected for automotive applications?

A: B340B-13-F and B340BQ-13-F both carry AEC-Q101 automotive qualification and are recommended for automotive applications. Both are active products from Diodes Incorporated with full automotive process compliance.

Q: Is there a performance difference between Diodes Incorporated and alternative manufacturer parts?

A: All substitute parts meet identical electrical specifications for voltage, current, forward voltage, and recovery speed. Secondary parameters such as junction capacitance vary slightly but do not affect functional performance in standard rectifier applications. Selection should be based on supply chain, qualification requirements, and inventory availability.

Q: Can multiple substitute parts be used interchangeably in production?

A: Yes. All identified substitute parts are parametrically equivalent and meet the same electrical and mechanical requirements. Multi-source qualification is supported by the availability of parts from Diodes Incorporated, Micro Commercial Co, and Panjit International Inc.
