CS2D-E3/H Equivalent & Substitute Parts

Part Overview

The CS2D-E3/H is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement continuity. The CS2D-E3/H operates across a junction temperature range of -55°C to 150°C and is suitable for standard recovery applications requiring rectification at moderate voltage and current levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS2D-E3/H is determined by equivalence in the following critical parameters:

• Voltage Rating (Vr): The substitute must maintain the same 200 V DC reverse voltage rating to ensure circuit protection and reliability.
• Package Type: The substitute must use the DO-214AA (SMB) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.
• Mounting Technology: Surface mount compatibility is required for automated assembly processes.
• Operating Temperature Range: The substitute must support the -55°C to 150°C junction temperature range.
• Current Rating: The substitute current rating must not exceed the design requirements of the application circuit.

The S2D-E3/52T meets these substitution criteria with identical voltage rating, package type, mounting technology, and operating temperature range. The current rating of 1.5 A on the substitute is lower than the original 2 A specification, making it suitable for applications designed for the CS2D-E3/H only when circuit current demands do not exceed 1.5 A.

Parameter Comparison

Engineering Selection Recommendations

The S2D-E3/52T is the designated manufacturer substitute for the obsolete CS2D-E3/H. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical voltage ratings, package types, and operating temperature ranges.

The S2D-E3/52T offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The part is RoHS3 compliant and carries Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life without moisture control requirements.

The primary design consideration is the reduced average rectified current rating of 1.5 A on the substitute compared to 2 A on the original part. Circuit designs operating at or below 1.5 A average rectified current are directly compatible with the S2D-E3/52T. Applications requiring the full 2 A rating must be evaluated against alternative rectifier diodes with equivalent voltage and package specifications.

Both parts carry REACH Unaffected status and EAR99 ECCN classification, indicating no additional regulatory restrictions on substitution.

Frequently Asked Questions (FAQ)

Q: Can the S2D-E3/52T directly replace the CS2D-E3/H in all applications?

A: Direct replacement is possible only in applications where the average rectified current does not exceed 1.5 A. The substitute part has a lower current rating (1.5 A versus 2 A) than the original. Voltage rating, package type, and operating temperature range are identical, ensuring mechanical and thermal compatibility.

Q: What is the significance of the obsolete status of the CS2D-E3/H?

A: Obsolete status indicates the part is no longer manufactured or supported by Vishay. The S2D-E3/52T, with active product status, is the recommended path for new designs and ongoing procurement to ensure supply availability and manufacturer support.

Q: Are there differences in forward voltage drop between the two parts?

A: The forward voltage specifications differ due to the different current ratings. The CS2D-E3/H specifies 1.2 V maximum at 2 A, while the S2D-E3/52T specifies 1.15 V maximum at 1.5 A. These values are not directly comparable due to different test conditions and current levels.

Q: Do both parts use the same package and mounting technology?

A: Yes. Both the CS2D-E3/H and S2D-E3/52T use the DO-214AA (SMB) surface mount package. PCB footprints and automated assembly processes are identical between the two parts.

Q: What is the difference in reverse leakage current between these parts?

A: The S2D-E3/52T exhibits lower reverse leakage current (1 µA @ 200 V) compared to the CS2D-E3/H (5 µA @ 200 V). Lower leakage current can reduce power dissipation in reverse bias conditions.

Q: Are there compliance or regulatory differences between the two parts?

A: Both parts carry identical REACH Unaffected and EAR99 ECCN classifications. The S2D-E3/52T includes RoHS3 compliance certification and MSL 1 moisture sensitivity rating, providing additional regulatory documentation for modern supply chain requirements.

Q: What is the reverse recovery time difference, and does it matter for my application?

A: The S2D-E3/52T has a reverse recovery time of 2 µs compared to 2.1 µs for the CS2D-E3/H. Both parts are classified as standard recovery diodes. The difference is negligible for most general-purpose rectification applications.
