B320BE-13 Equivalent & Substitute Parts

Part Overview

The B320BE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 20V DC reverse voltage and 3A average rectified current in a surface mount SMB (DO-214AA) package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, production continuity, and component sourcing.

Schottky diodes in this voltage and current class are commonly used in power supply circuits, reverse polarity protection, and high-frequency rectification applications where low forward voltage drop and fast recovery characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B320BE-13 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Maximum DC reverse voltage must equal or exceed 20V
• Current Rating: Average rectified current must equal or exceed 3A
• Forward Voltage Drop: Maximum forward voltage at rated current must not exceed 500 mV @ 3A
• Recovery Speed: Fast recovery characteristic ≤ 500ns for > 200mA
• Package: Surface mount DO-214AA (SMB) form factor
• Technology: Schottky diode construction
• Temperature Range: Operating junction temperature range -55°C to 150°C

Two substitute parts meet these electrical and mechanical criteria: B320B-13-F (Diodes Incorporated) and SK32B-LTP (Micro Commercial Co). Both maintain identical voltage, current, forward voltage, recovery speed, package configuration, and temperature specifications as the main part.

Parameter Comparison

Engineering Selection Recommendations

B320B-13-F (Diodes Incorporated) is the primary substitute for the obsolete B320BE-13. This part is manufactured by the same supplier as the original component, maintains identical electrical specifications, and carries active product status. The B320B-13-F is qualified to AEC-Q101 automotive standards and is available in Tape & Reel packaging with unlimited moisture sensitivity level (MSL 1). This part is suitable for both new designs and replacement applications.

SK32B-LTP (Micro Commercial Co) is an alternative substitute that meets all critical electrical and mechanical parameters. However, this part carries a "Not For New Designs" product status designation, indicating it is in mature or declining production phase. The SK32B-LTP is available in Cut Tape and Digi-Reel packaging formats. This part is appropriate for legacy system maintenance and repair applications where component continuity is required.

Both substitute parts are ROHS3 compliant and carry EAR99 ECCN classification matching the original component. Selection between B320B-13-F and SK32B-LTP should be based on application requirements, production volume, and long-term component availability strategy.

Frequently Asked Questions (FAQ)

Q: Can B320B-13-F directly replace B320BE-13 in existing designs?

A: Yes. The B320B-13-F maintains identical electrical ratings (20V, 3A, 500mV forward voltage, fast recovery ≤ 500ns) and package configuration (DO-214AA SMB surface mount). Both components are ROHS3 compliant with matching temperature operating ranges (-55°C to 150°C). The primary difference is product status: B320B-13-F is active while B320BE-13 is obsolete.

Q: What is the difference between B320B-13-F and SK32B-LTP?

A: Both parts meet identical electrical specifications and package requirements. The key differences are: (1) Manufacturer—B320B-13-F is Diodes Incorporated; SK32B-LTP is Micro Commercial Co; (2) Product Status—B320B-13-F is Active; SK32B-LTP is Not For New Designs; (3) Packaging—B320B-13-F is supplied in Tape & Reel; SK32B-LTP is supplied in Cut Tape and Digi-Reel; (4) Reverse Leakage—B320BE-13 specifies 100µA while both substitutes specify 500µA at 20V.

Q: Are there any compliance or certification differences between the substitutes?

A: B320B-13-F carries AEC-Q101 automotive qualification and is REACH Unaffected. B320BE-13 and SK32B-LTP are REACH Affected. All three parts are ROHS3 compliant and carry EAR99 ECCN classification. For automotive applications, B320B-13-F is the appropriate selection.

Q: Why does B320B-13-F show higher reverse leakage current than B320BE-13?

A: The reverse leakage specification difference (500µA versus 100µA at 20V) reflects manufacturing process variations and characterization methods between the obsolete part and active production alternatives. Both values remain within acceptable limits for typical Schottky diode applications. Circuit designs should accommodate the higher leakage specification of the substitute parts.

Q: Is SK32B-LTP suitable for new product designs?

A: No. SK32B-LTP carries a "Not For New Designs" product status designation. This part is appropriate for maintenance, repair, and legacy system support only. For new designs, B320B-13-F is the recommended substitute.

Q: What packaging options are available for each substitute?

A: B320B-13-F is supplied in Tape & Reel (TR) format. SK32B-LTP is supplied in Cut Tape (CT) and Digi-Reel format. Both maintain the same DO-214AA SMB package footprint and are compatible with standard surface mount assembly processes.
