Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES2B-LTP is determined by equivalence in the following critical electrical parameters:

• Voltage Rating: Reverse voltage (Vr) must be 100V or greater
• Current Rating: Average rectified current (Io) must be 2A or greater
• Package Type: Surface mount DO-214AC (SMA) package required for mechanical compatibility
• Speed Classification: Fast recovery diode classification (≤ 500ns, > 200mA)
• Compliance: RoHS3 compliance and MSL Level 1 required for supply chain compatibility

The ES2BA-13-F from Diodes Incorporated meets all substitution criteria with identical voltage and current ratings, matching package designation, and equivalent fast recovery characteristics. This part is classified as "Active" in the manufacturer's product line, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The ES2BA-13-F from Diodes Incorporated is the direct substitute for the ES2B-LTP. Selection of this substitute part is supported by the following factors:

Electrical Equivalence: Both parts share identical voltage and current ratings (100V, 2A), matching reverse leakage current specifications, and equivalent fast recovery speed classification. The ES2BA-13-F demonstrates superior performance characteristics with lower forward voltage drop (920 mV vs. 950 mV) and faster reverse recovery time (25 ns vs. 35 ns).

Compliance and Certification: Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard supply chain and manufacturing processes. REACH and ECCN classifications are identical.

Product Status: The ES2BA-13-F carries "Active" product status with confirmed inventory availability (34,605 units), whereas the ES2B-LTP is designated "Not For New Designs." This distinction makes the ES2BA-13-F the appropriate choice for both replacement and new design applications.

Package Compatibility: Both parts utilize the DO-214AC (SMA) surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Operating Temperature Consideration: The ES2BA-13-F operates within -55°C to 150°C, which is a subset of the ES2B-LTP range (-65°C to 175°C). Applications requiring operation below -55°C or above 150°C must retain the ES2B-LTP or identify alternative parts with extended temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the ES2BA-13-F directly replace the ES2B-LTP in existing designs?

A: Yes. Both parts share identical voltage ratings (100V), current ratings (2A), package type (DO-214AC/SMA), and fast recovery speed classification. The ES2BA-13-F is electrically and mechanically compatible for direct substitution in standard applications.

Q: What are the differences in electrical performance between these parts?

A: The ES2BA-13-F exhibits lower forward voltage drop (920 mV vs. 950 mV at 2A) and faster reverse recovery time (25 ns vs. 35 ns). These differences represent improved performance characteristics. Capacitance is slightly higher in the ES2BA-13-F (25 pF vs. 15 pF at 4V, 1MHz), which may affect high-frequency circuit behavior.

Q: Are there temperature range limitations when substituting?

A: The ES2BA-13-F operates within -55°C to 150°C, compared to the ES2B-LTP range of -65°C to 175°C. Applications requiring junction temperatures below -55°C or above 150°C must evaluate alternative parts or retain the original ES2B-LTP.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ES2B-LTP and ES2BA-13-F are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (unlimited moisture sensitivity). ECCN and HTSUS classifications are identical.

Q: Why is the ES2B-LTP marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. The ES2BA-13-F from Diodes Incorporated is the recommended substitute for new design implementations, offering active product status and confirmed long-term availability.

Q: Are packaging options different between these parts?

A: The ES2B-LTP is supplied in Cut Tape (CT) packaging. The ES2BA-13-F is available in both Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility in procurement quantities and handling methods.

Q: What is the impact of higher capacitance in the ES2BA-13-F?

A: The ES2BA-13-F capacitance of 25 pF (vs. 15 pF) may affect switching behavior in high-frequency applications. Circuit simulation or bench testing is appropriate for applications operating above 1 MHz where capacitive effects influence performance.
