Engineering Selection Recommendations

Primary Selection: SA2G-E3/61T

The SA2G-E3/61T is the direct substitute for the obsolete CSA2G-E3/H. Selection of this part is based on:

• Product Status: The substitute is actively manufactured and maintained by Vishay General Semiconductor - Diodes Division, ensuring long-term availability and supply chain stability.
• Electrical Equivalence: All critical electrical parameters—reverse voltage rating, average rectified current, forward voltage, and reverse leakage current—are within or superior to the original specification.
• Mechanical Compatibility: Both parts use identical DO-214AC (SMA) surface mount packaging, enabling direct PCB layout compatibility without redesign.
• Regulatory Compliance: The substitute maintains REACH Unaffected status and EAR99 export classification, matching the original part's compliance profile.
• RoHS3 Compliance: The SA2G-E3/61T is RoHS3 compliant, meeting current environmental standards.
• Packaging Format: The substitute is supplied in Tape & Reel (TR) format, standard for high-volume production environments.

The SA2G-E3/61T exhibits improved performance characteristics, including lower forward voltage (1.1 V vs. 1.15 V) and faster reverse recovery time (1.5 µs vs. 2.1 µs), while maintaining full backward compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the SA2G-E3/61T be used as a direct replacement for the CSA2G-E3/H without circuit modification?

A: Yes. The SA2G-E3/61T is electrically and mechanically equivalent to the CSA2G-E3/H. Both diodes share identical voltage ratings (400 V), current ratings (2 A), package type (DO-214AC/SMA), and operating temperature range (-55°C to 150°C). No circuit redesign is required.

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

A: The CSA2G-E3/H has a maximum forward voltage of 1.15 V at 2 A, while the SA2G-E3/61T has a maximum forward voltage of 1.1 V at 2 A. The substitute exhibits lower forward voltage, resulting in reduced power dissipation in the same application.

Q: How do the reverse recovery times compare?

A: The CSA2G-E3/H has a reverse recovery time of 2.1 µs, while the SA2G-E3/61T has a reverse recovery time of 1.5 µs. The faster recovery time of the substitute may improve switching performance in high-frequency applications.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AC (SMA) surface mount package. The CSA2G-E3/H is supplied in standard packaging, while the SA2G-E3/61T is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Why is the CSA2G-E3/H classified as obsolete?

A: The CSA2G-E3/H is no longer actively manufactured by Vishay General Semiconductor - Diodes Division. The SA2G-E3/61T represents the current active product line for this diode specification.

Q: Are both parts compliant with current environmental regulations?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The SA2G-E3/61T additionally carries RoHS3 compliance certification, meeting current environmental standards for electronic components.

Q: What is the reverse leakage current difference?

A: The CSA2G-E3/H has a maximum reverse leakage current of 5 µA at 400 V, while the SA2G-E3/61T has a maximum reverse leakage current of 3 µA at 400 V. The lower leakage current of the substitute indicates improved reverse blocking characteristics.
