ES2BH Equivalent & Substitute Parts

Part Overview

The ES2BH 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-214AA (SMB) package. This component is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds, suitable for standard rectification applications requiring automotive-grade reliability.

The ES2BH maintains Active product status with AEC-Q101 automotive qualification. Substitute parts are identified to provide design flexibility when the primary part becomes unavailable or when alternative sourcing is required for procurement optimization.

Substitute Part Grouping Explanation

Substitution of the ES2BH is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
• Reverse Recovery Time (trr): 35 ns
• Package / Case: DO-214AA, SMB
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts meeting all mandatory criteria are classified as parametric equivalents. Minor variations in reverse leakage current (within the same order of magnitude) and capacitance do not disqualify substitution when all primary electrical ratings and package specifications are identical.

Engineering Selection Recommendations

ES2B R5G (Taiwan Semiconductor Corporation)

The ES2B R5G is a parametric equivalent to the ES2BH with identical electrical specifications and package configuration. This part is currently Discontinued at DiGi Electronics. Selection of this substitute should be evaluated based on alternative supplier availability and procurement lead times. The part maintains full compliance with ROHS3, REACH, and automotive standards equivalent to the main part.

ER2B_R1_00001 (Panjit International Inc.)

The ER2B_R1_00001 is a parametric equivalent manufactured by Panjit International Inc., meeting all critical electrical and mechanical specifications of the ES2BH. This part maintains Active product status and is available in Tape & Reel (TR) packaging. The reverse leakage current specification is superior (1 µA versus 10 µA), representing an improvement in leakage performance. Full compliance with ROHS3, REACH, and automotive standards is maintained. This substitute is suitable for direct replacement in applications where the ES2BH is specified.

Both substitute parts are qualified for automotive applications and maintain identical thermal operating ranges, making them suitable for equivalent circuit performance in rectification applications.

Frequently Asked Questions (FAQ)

Q: Can ES2B R5G be used as a direct replacement for ES2BH?

A: Yes. The ES2B R5G meets all mandatory electrical and mechanical parameters of the ES2BH, including voltage rating, current rating, forward voltage drop, reverse recovery time, and DO-214AA package specification. The primary consideration is product availability, as this part is Discontinued at DiGi Electronics.

Q: What is the difference between ES2BH and ER2B_R1_00001?

A: Both parts are parametric equivalents with identical voltage, current, and thermal ratings. The ER2B_R1_00001 has a lower reverse leakage current specification (1 µA versus 10 µA at 100 V), which represents improved leakage performance. Both are packaged in DO-214AA (SMB) and maintain equivalent fast recovery characteristics.

Q: Are the substitute parts automotive-qualified?

A: The ES2B R5G carries ROHS3 compliance and REACH Unaffected status. The ER2B_R1_00001 is Active and carries ROHS3 compliance and REACH Unaffected status. Both parts maintain compliance with the same regulatory standards as the ES2BH. Verification of specific automotive qualification requirements (such as AEC-Q101) should be confirmed with the respective manufacturer datasheets.

Q: Can these diodes be used interchangeably in the same PCB layout?

A: Yes. All three parts use the identical DO-214AA (SMB) package, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) and Digi-Reel® packaging is suitable for manual assembly and smaller quantity orders. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment and higher volume production. Both packaging formats contain the same component; the selection depends on assembly process requirements.

Q: Are there any temperature or environmental limitations for these substitutes?

A: All three parts operate across the identical junction temperature range of -55°C to 150°C. All maintain Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints. Storage and handling requirements are equivalent across all three parts.
