ES2BA Equivalent & Substitute Parts

Part Overview

The ES2BA is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The ES2BA serves as a standard fast recovery diode for power conversion and protection circuits requiring moderate current handling at 100 V operation.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and address component availability across different manufacturers and packaging formats while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ES2BA are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: 100 V reverse voltage rating, 2 A average rectified current, 950 mV forward voltage drop at 2 A, 35 ns reverse recovery time, and DO-214AC (SMA) package compatibility. These parts are direct functional replacements with no circuit redesign required.

Similar Parts share the same voltage and package specifications but differ in one or more electrical parameters, including average rectified current rating, forward voltage characteristics, reverse recovery time, reverse leakage current, or operating temperature range. Selection of similar parts requires verification that the application tolerates the parameter deviation.

The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 100 V
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Current - Average Rectified (Io): 2 A (for parametric equivalents)

Engineering Selection Recommendations

Parametric Equivalents for Direct Substitution:

ES2B_R1_00001 (Panjit International Inc.) is a parametric equivalent offering identical electrical specifications to the ES2BA with superior reverse leakage current performance (1 µA versus 10 µA at 100 V). This part maintains Active product status and is suitable for new designs. The ES2B_R1_00001 is available in Tape & Reel packaging and carries ROHS3 compliance with unlimited MSL rating.

ES2BA R3G (Taiwan Semiconductor Corporation) is a parametric equivalent with identical electrical characteristics. However, this part is marked as Discontinued at DiGi Electronics and should not be selected for new designs. Existing inventory may be available through alternative distribution channels.

Similar Parts with Parameter Deviations:

ES2B-LTP (Micro Commercial Co) maintains 100 V reverse voltage and 2 A current ratings with identical forward voltage and recovery time specifications. This part is marked as Not For New Designs and exhibits lower reverse leakage current (5 µA) and reduced capacitance (15 pF). The extended operating temperature range (-65°C ~ 175°C) provides thermal margin beyond the ES2BA specification. Use of ES2B-LTP is restricted to legacy designs or applications where the extended temperature range provides specific value.

RS1B-13-F (Diodes Incorporated) is a similar part with reduced current rating (1 A versus 2 A) and higher forward voltage drop (1.3 V @ 1 A versus 950 mV @ 2 A). The reverse recovery time is significantly longer (150 ns versus 35 ns). This part is suitable only for applications where the 1 A current rating is sufficient and the slower recovery time does not impact circuit performance. RS1B-13-F maintains Active product status and is available in Tape & Reel packaging.

Compliance and Certification:

All substitute parts carry ROHS3 compliance and unlimited MSL rating, matching the ES2BA environmental and regulatory status. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080, maintaining consistent export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can ES2B_R1_00001 be used as a direct replacement for ES2BA in production?

A: Yes. ES2B_R1_00001 is a parametric equivalent with identical voltage, current, forward voltage, and recovery time specifications. The superior reverse leakage current (1 µA versus 10 µA) represents improved performance. Both parts use DO-214AC (SMA) surface mount packaging and maintain ROHS3 compliance. Substitution requires no circuit modification.

Q: What is the difference between ES2BA and RS1B-13-F?

A: RS1B-13-F has a reduced average rectified current rating of 1 A compared to the ES2BA 2 A rating. Forward voltage is higher at 1.3 V @ 1 A versus 950 mV @ 2 A. Reverse recovery time is significantly longer at 150 ns versus 35 ns. RS1B-13-F is suitable only for applications where 1 A current capacity is adequate and slower switching speed is acceptable.

Q: Why is ES2BA R3G listed as a substitute if it is discontinued?

A: ES2BA R3G is a parametric equivalent with identical electrical specifications and is included for reference in legacy designs or where existing inventory is available. For new designs, ES2B_R1_00001 or the primary ES2BA part are recommended.

Q: Are all substitute parts available in the same packaging format as ES2BA?

A: No. ES2BA is supplied in Tape & Reel (TR) format. ES2BA R3G and ES2B-LTP are supplied in Cut Tape (CT) format. ES2B_R1_00001 and RS1B-13-F are supplied in Tape & Reel (TR) format. All parts use identical DO-214AC (SMA) surface mount package geometry and are compatible with standard pick-and-place assembly equipment. Packaging format selection depends on production volume and handling requirements.

Q: Can ES2B-LTP be used in applications requiring the full -55°C to 150°C temperature range of ES2BA?

A: Yes. ES2B-LTP supports an extended operating temperature range of -65°C to 175°C, which encompasses the ES2BA specification of -55°C to 150°C. However, ES2B-LTP is marked as Not For New Designs and should be used only in legacy applications where existing qualification exists.

Q: What is the significance of reverse leakage current differences among substitute parts?

A: Reverse leakage current affects power dissipation and circuit performance in high-impedance applications. ES2B_R1_00001 exhibits the lowest leakage at 1 µA, followed by ES2B-LTP and RS1B-13-F at 5 µA, and ES2BA at 10 µA. For most general-purpose rectification applications, these differences are negligible. Selection based on leakage current is necessary only in precision analog circuits or high-temperature environments where leakage becomes significant.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the ES2BA environmental standard. All parts are classified as REACH Unaffected and maintain identical ECCN and HTSUS classifications.
