Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BYG24D-M3/TR are identified based on the following critical electrical and mechanical parameters:

Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1.5 A
• Package / Case: DO-214AC, SMA (surface mount)
• Mounting Type: Surface Mount
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The S2DA-13-F from Diodes Incorporated satisfies all matching criteria. While the S2DA-13-F employs standard recovery technology (>500 ns) compared to the fast recovery specification (≤500 ns) of the BYG24D-M3/TR, both devices share identical voltage and current ratings, identical package configuration, and equivalent compliance certifications. The forward voltage characteristic of the S2DA-13-F (1.15 V @ 1.5 A) is lower than the BYG24D-M3/TR (1.25 V @ 1.5 A), representing improved efficiency in forward conduction.

Parameter Comparison

Engineering Selection Recommendations

BYG24D-M3/TR Selection Criteria: The BYG24D-M3/TR is the primary choice for applications requiring fast recovery characteristics (140 ns reverse recovery time). This specification is essential in high-frequency switching circuits, power factor correction stages, and applications where switching losses must be minimized. The part maintains Active product status with full RoHS3 and REACH compliance, ensuring regulatory conformance for industrial and consumer applications.

S2DA-13-F Selection Criteria: The S2DA-13-F serves as a functional equivalent for applications where recovery speed is not a critical design parameter. This substitute offers superior forward voltage performance (1.15 V versus 1.25 V), resulting in lower conduction losses and reduced thermal dissipation. The extended lower operating temperature limit (-65°C versus -55°C) provides additional thermal margin in cold environment applications. The S2DA-13-F maintains identical voltage and current ratings, package configuration, and compliance certifications. Selection of this substitute is appropriate for general-purpose rectification, power supply applications, and circuits where standard recovery diode performance is sufficient.

Both parts are Active products with unlimited moisture sensitivity rating and full regulatory compliance, ensuring long-term availability and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can the S2DA-13-F directly replace the BYG24D-M3/TR in all applications?

A: Direct replacement is possible in applications where diode recovery speed does not affect circuit performance. The S2DA-13-F is suitable for general-purpose rectification and power supply applications. Applications requiring fast recovery characteristics (high-frequency switching, PFC stages, or circuits sensitive to reverse recovery current) require the BYG24D-M3/TR or equivalent fast recovery diode.

Q: What is the significance of the reverse recovery time difference?

A: The BYG24D-M3/TR specifies 140 ns reverse recovery time (fast recovery), while the S2DA-13-F employs standard recovery (>500 ns). In high-frequency applications, longer recovery time increases switching losses and electromagnetic interference. Fast recovery diodes are required for switching frequencies above approximately 100 kHz or in circuits where reverse recovery current must be minimized.

Q: Are both parts pin-compatible?

A: Yes. Both the BYG24D-M3/TR and S2DA-13-F use the DO-214AC (SMA) surface mount package with identical pin configuration and footprint. No PCB layout modifications are required for substitution.

Q: What is the impact of the forward voltage difference?

A: The S2DA-13-F exhibits lower forward voltage (1.15 V @ 1.5 A) compared to the BYG24D-M3/TR (1.25 V @ 1.5 A). This 0.1 V difference reduces conduction losses and heat generation in the substitute part, resulting in improved power efficiency. In high-current applications, this translates to measurable thermal benefits.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the BYG24D-M3/TR and S2DA-13-F are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both parts are classified as Active products with equivalent regulatory status.

Q: What is the reverse leakage current difference?

A: The BYG24D-M3/TR specifies 1 µA reverse leakage at 200 V, while the S2DA-13-F specifies 5 µA at the same rating. The lower leakage of the BYG24D-M3/TR is beneficial in precision analog circuits and high-impedance applications. For standard power supply and rectification applications, the 5 µA leakage of the S2DA-13-F is within acceptable limits.

Q: Can the S2DA-13-F be used in circuits designed for the BYG24D-M3/TR?

A: Substitution is valid when circuit design does not depend on fast recovery characteristics. Review the application schematic to confirm that switching frequency, reverse recovery current sensitivity, and leakage current specifications are compatible with the S2DA-13-F parameters. If the circuit operates at frequencies below 100 kHz and does not employ active reverse recovery current management, the S2DA-13-F is suitable.
