Substitute Part Grouping Explanation

Substitution of the B130BE-13 is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30V minimum
• Current - Average Rectified (Io): 1A minimum
• Voltage - Forward (Vf) (Max) @ If: 500mV or lower @ 1A
• Technology: Schottky rectifier
• Package / Case: DO-214AA or SMB compatible
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

• Operating Temperature Range: Must encompass or exceed the application's thermal requirements
• Speed Classification: Fast Recovery ≤ 500ns for > 200mA
• Current - Reverse Leakage: Acceptable within application circuit design limits

Substitute parts identified in this reference maintain electrical equivalence and mechanical compatibility with the B130BE-13 while offering improved product status or packaging options.

Engineering Selection Recommendations

B130B-13-F (Diodes Incorporated)

The B130B-13-F is the primary substitute for the B130BE-13. Both components are manufactured by Diodes Incorporated and share identical electrical specifications across voltage, current, and forward voltage parameters. The B130B-13-F holds Active product status, ensuring long-term availability and supply chain continuity. This part features an extended lower operating temperature limit (-65°C versus -55°C), providing enhanced thermal margin for demanding applications. Packaging is supplied in Tape & Reel format, supporting automated assembly processes. RoHS3 compliance and REACH Unaffected status confirm regulatory alignment. The B130B-13-F is the recommended primary substitute for new designs and production transitions.

SK13-LTP (Micro Commercial Co)

The SK13-LTP provides electrical equivalence across all critical parameters: 30V reverse voltage, 1A average rectified current, and 500mV forward voltage. This part maintains Fast Recovery Schottky technology and DO-214AA SMB package compatibility. However, the SK13-LTP carries a "Not For New Designs" product status, indicating limited future support and potential supply constraints. The operating temperature range (-55°C ~ 125°C) is narrower than the B130BE-13, with a maximum junction temperature 25°C lower. The SK13-LTP is suitable for legacy system maintenance and repair applications where component availability from existing inventory is confirmed, but is not recommended for new product development.

Frequently Asked Questions (FAQ)

Q: Can the B130B-13-F directly replace the B130BE-13 in existing circuit designs?

A: Yes. The B130B-13-F maintains electrical equivalence across all critical parameters: 30V reverse voltage, 1A average rectified current, 500mV forward voltage at 1A, and Fast Recovery Schottky technology. Both components use the DO-214AA SMB package and Surface Mount configuration. The B130B-13-F offers an extended lower operating temperature limit (-65°C), providing additional thermal margin.

Q: What is the difference between B130BE-13 and B130B-13-F packaging?

A: The B130BE-13 is supplied in bulk packaging, while the B130B-13-F is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and provides improved component protection during handling and storage.

Q: Why is the SK13-LTP marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Micro Commercial Co has discontinued active development and support for this component. While the SK13-LTP remains electrically equivalent, it is subject to potential supply discontinuation and limited technical support. This status restricts its use to legacy system maintenance and repair applications.

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

A: Yes. The B130BE-13 specifies 100 µA reverse leakage at 30V, while both the B130B-13-F and SK13-LTP specify 500 µA at 30V. This difference is acceptable for most rectifier applications. Circuit designs with strict leakage current requirements should evaluate this parameter against application specifications.

Q: What is the significance of capacitance differences between these parts?

A: The B130BE-13 specifies 50pF capacitance at 4V and 1MHz, while the B130B-13-F specifies 110pF and the SK13-LTP specifies 130pF. Higher capacitance may affect high-frequency circuit performance and switching characteristics. Applications operating at frequencies above 1MHz should evaluate capacitance impact on circuit behavior.

Q: Are all three parts RoHS3 compliant?

A: Yes. The B130BE-13, B130B-13-F, and SK13-LTP are all ROHS3 Compliant, confirming compliance with Restriction of Hazardous Substances regulations.

Q: What is the difference in operating temperature ranges?

A: The B130BE-13 operates from -55°C to 150°C. The B130B-13-F extends the lower limit to -65°C, providing 10°C additional margin at low temperatures. The SK13-LTP operates from -55°C to 125°C, with a 25°C reduction in maximum junction temperature. Applications requiring operation below -55°C or above 125°C should select the B130B-13-F.
