ES2A Equivalent & Substitute Parts

Part Overview

The ES2A is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 2 A average rectified current. The device is packaged in DO-214AA (SMB) surface mount configuration and is classified as a fast recovery diode with a reverse recovery time of 35 ns. This component is suitable for applications requiring efficient rectification in power supply circuits, converter stages, and general switching applications. The ES2A maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance parameters are available from alternative manufacturers, enabling design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the ES2A rectifier diode is determined by equivalence in the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
• Current - Average Rectified (Io): Must equal or exceed 2 A
• Speed Classification: Must maintain Fast Recovery characteristics (≤ 500ns, > 200mA)
• Package / Case: Must be compatible surface mount configuration
• Operating Temperature Range: Must encompass or exceed -55°C to 150°C junction temperature range
• RoHS3 Compliance: Required for regulatory equivalence
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Secondary Compatibility Factors:

• Reverse Recovery Time (trr): Lower values indicate superior switching performance
• Forward Voltage (Vf): Lower values reduce power dissipation
• Reverse Leakage Current: Lower values improve efficiency

The RS2A-13-F from Diodes Incorporated is evaluated against these criteria to determine substitution feasibility.

Engineering Selection Recommendations

ES2A (Primary Selection): The ES2A is the specified component for applications requiring 2 A average rectified current at 50 V reverse voltage with fast recovery characteristics. This part maintains Active product status, full RoHS3 compliance, and unlimited moisture sensitivity rating. The 35 ns reverse recovery time and 950 mV forward voltage at 2 A provide optimized performance for standard rectification applications. The DO-214AA (SMB) package is the original design footprint.

RS2A-13-F (Substitute Consideration): The RS2A-13-F from Diodes Incorporated shares equivalent reverse voltage rating (50 V) and fast recovery speed classification. However, the current rating is reduced to 1.5 A, which does not meet the 2 A specification of the ES2A. The reverse recovery time is 150 ns compared to 35 ns in the ES2A, indicating slower switching performance. The package footprint differs (DO-214AC SMA versus DO-214AA SMB), requiring PCB layout modification. The RS2A-13-F maintains RoHS3 compliance and MSL 1 rating. This substitute is not electrically equivalent for applications requiring full 2 A current capacity.

Compliance Status: Both parts maintain Active product status, RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Both are suitable for applications with unlimited moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can the RS2A-13-F directly replace the ES2A in my circuit?

A: No. The RS2A-13-F has a maximum average rectified current rating of 1.5 A, while the ES2A is rated for 2 A. Direct substitution in circuits designed for 2 A operation will result in component overstress and potential failure. The package footprints also differ (SMA versus SMB), requiring PCB modification.

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

A: The ES2A has a reverse recovery time of 35 ns, while the RS2A-13-F has 150 ns. Faster recovery time reduces switching losses and improves efficiency in high-frequency applications. The ES2A is superior for applications where switching speed is critical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ES2A and RS2A-13-F are RoHS3 compliant and suitable for applications requiring lead-free, halogen-free construction.

Q: What is the difference between DO-214AA (SMB) and DO-214AC (SMA) packages?

A: DO-214AA (SMB) and DO-214AC (SMA) are different surface mount package footprints with different land patterns and dimensions. They are not mechanically interchangeable without PCB redesign. The ES2A uses DO-214AA; the RS2A-13-F uses DO-214AC.

Q: Can I use the RS2A-13-F in a lower-current application where the ES2A was originally specified?

A: The RS2A-13-F can be used in applications where the actual operating current does not exceed 1.5 A, provided the package footprint change is accommodated in the PCB design. However, this represents a design change from the original specification and requires engineering review.

Q: What is the moisture sensitivity level (MSL) rating, and why does it matter?

A: Both parts have MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture control during storage or handling. This simplifies supply chain management and reduces component preparation requirements.

Q: Are there any temperature range differences between these parts?

A: The ES2A operates from -55°C to 150°C junction temperature, while the RS2A-13-F operates from -65°C to 150°C. The RS2A-13-F has a wider low-temperature range, but both cover standard industrial and commercial temperature requirements.
