Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BYG24D-M3/TR3 is determined by the following critical parameters:

Mandatory Matching Parameters:

• 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

Allowable Parameter Variations:

• Voltage - Forward (Vf) (Max) @ If: Substitute values must not exceed the main part specification to ensure equivalent or superior performance
• Reverse Recovery Time (trr): Substitute values may differ; fast recovery and standard recovery technologies are both acceptable for general rectification applications
• Current - Reverse Leakage @ Vr: Substitute values may vary; higher leakage is acceptable within normal diode operating parameters
• Operating Temperature - Junction: Substitute range must encompass or exceed the main part range
• Technology: Both avalanche and standard rectifier technologies are acceptable when voltage and current ratings match

Compliance Requirements:

• RoHS3 compliance required
• Active product status required

Parameter Comparison

Engineering Selection Recommendations

The S2DA-13-F from Diodes Incorporated qualifies as a direct substitute for the BYG24D-M3/TR3 based on the following criteria:

Electrical Compatibility: Both parts maintain identical voltage and current ratings (200 V, 1.5 A), ensuring functional equivalence in rectification applications. The S2DA-13-F exhibits a lower forward voltage drop (1.15 V versus 1.25 V), which represents improved efficiency characteristics. The substitute part operates across a wider temperature range (-65 to 150 °C versus -55 to 150 °C), providing extended thermal operating capability.

Mechanical Compatibility: Both components utilize the DO-214AC (SMA) surface mount package, ensuring identical PCB footprint, land pattern, and reflow soldering compatibility.

Compliance and Status: Both parts maintain Active product status and ROHS3 compliance, meeting current regulatory and supply chain requirements. Both carry unlimited moisture sensitivity rating (MSL 1), eliminating special handling or storage considerations.

Technology Consideration: The BYG24D-M3/TR3 employs avalanche technology with fast recovery characteristics (140 ns), while the S2DA-13-F uses standard rectifier technology. For applications requiring fast switching or high-frequency operation, the technology difference must be evaluated against specific circuit requirements. For general rectification applications, both technologies are functionally compatible.

Frequently Asked Questions (FAQ)

Q: Can the S2DA-13-F directly replace the BYG24D-M3/TR3 on existing PCBs?

A: Yes. Both components share identical DO-214AC (SMA) package specifications, including footprint, land pattern, and lead spacing. No PCB modifications are required for mechanical or electrical interface compatibility.

Q: What is the significance of the forward voltage difference between these parts?

A: The S2DA-13-F exhibits a forward voltage of 1.15 V compared to the BYG24D-M3/TR3 at 1.25 V, both measured at 1.5 A. This 0.1 V difference results in lower power dissipation and improved efficiency in the substitute part. For most applications, this represents a performance improvement.

Q: Why does the BYG24D-M3/TR3 specify fast recovery while the S2DA-13-F does not?

A: The BYG24D-M3/TR3 uses avalanche diode technology with a specified reverse recovery time of 140 ns (fast recovery). The S2DA-13-F employs standard rectifier technology without a specified recovery time. Fast recovery is beneficial for high-frequency switching applications. For DC rectification or low-frequency applications, standard recovery technology is functionally equivalent.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical EAR99 and HTSUS classifications. Both maintain Active product status and unlimited moisture sensitivity rating (MSL 1).

Q: What is the impact of the higher reverse leakage current in the S2DA-13-F?

A: The S2DA-13-F specifies 5 µA reverse leakage at 200 V compared to 1 µA for the BYG24D-M3/TR3. This difference is within normal diode operating parameters and does not affect functional compatibility for standard rectification applications. Applications with stringent leakage requirements should evaluate this parameter against circuit specifications.

Q: Does the wider operating temperature range of the S2DA-13-F provide any advantage?

A: The S2DA-13-F operates from -65 to 150 °C compared to -55 to 150 °C for the BYG24D-M3/TR3. The extended lower temperature limit provides additional thermal margin for applications operating in cold environments. Both parts meet the same upper temperature limit.

Q: Are both parts available in the same packaging format?

A: Yes. Both the BYG24D-M3/TR3 and S2DA-13-F are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The supplier device package designation is DO-214AC (SMA) for both components.
