ES2GHE3_A/I Equivalent & Substitute Parts

Part Overview

The ES2GHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 400 V DC reverse voltage with 2 A average rectified current in a DO-214AA (SMB) package. The device is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and manufacturing optimization. Alternative part numbers within the same electrical and mechanical specifications enable component sourcing from multiple suppliers and packaging formats while maintaining circuit performance.

Substitute Part Grouping Explanation

Substitute parts for the ES2GHE3_A/I are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Vishay General Semiconductor - Diodes Division): These parts maintain identical electrical specifications for voltage (400 V), current (2 A), and package format (DO-214AA SMB). Substitution is determined by matching reverse voltage, average rectified current, forward voltage, and junction temperature range. Differences in reverse recovery time (50 ns versus 35 ns) and reverse leakage measurement conditions do not preclude substitution within standard rectifier applications. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical performance.

Manufacturer Recommended Alternatives: These parts are sourced from alternative manufacturers (Central Semiconductor Corp, Panjit International Inc.) and maintain the same 400 V reverse voltage and DO-214AA SMB package. Selection criteria include matching voltage rating, current capability, and package format. The CMR1U-04 TR13 PBFREE operates at 1 A (reduced current rating) and is suitable only for applications with lower current requirements. The ER2G_R1_00001 maintains full 2 A current rating with equivalent electrical performance.

Key Parameters for Substitution:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 2 A (or lower for reduced-current applications)
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C minimum

Engineering Selection Recommendations

Vishay Parametric Equivalents (ES2G-E3/52T, ES2G-E3/5BT, ES2G-M3/52T): These parts are direct electrical equivalents with identical voltage and current ratings. Selection between these options is determined by packaging format requirements. ES2G-E3/52T is supplied in Cut Tape format for manual or semi-automated assembly. ES2G-E3/5BT and ES2G-M3/52T are supplied in Tape & Reel format for automated pick-and-place assembly. All three maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The ES2GHE3_A/I retains automotive grade classification and AEC-Q101 qualification; the parametric equivalents do not specify automotive qualification.

Central Semiconductor CMR1U-04 TR13 PBFREE: This part is suitable only for applications where the average rectified current requirement is 1 A or less. The 400 V reverse voltage rating is equivalent; however, the reduced current capability restricts its use to lower-power circuits. Operating temperature range extends to 175°C maximum junction temperature, providing thermal margin beyond the ES2GHE3_A/I specification. ROHS3 compliance and MSL 1 rating are maintained.

Panjit International ER2G_R1_00001: This part maintains full 2 A current capability and 400 V reverse voltage rating with equivalent reverse recovery time (35 ns). Forward voltage is specified at 1.25 V versus 1.1 V for the ES2GHE3_A/I, representing a 0.15 V increase at rated current. Reverse leakage current is significantly lower (1 µA at 400 V versus 10 µA at 50 V), indicating superior reverse blocking characteristics. ROHS3 compliance and MSL 1 rating are maintained. Operating temperature range matches the ES2GHE3_A/I specification.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The ES2GHE3_A/I is the only part with specified automotive grade and AEC-Q101 qualification. Applications requiring automotive qualification must retain the ES2GHE3_A/I or verify alternative part qualification status with the respective manufacturer.

Frequently Asked Questions (FAQ)

Q: Can ES2G-E3/52T replace ES2GHE3_A/I in automotive applications?

A: ES2G-E3/52T is electrically equivalent with matching 400 V and 2 A ratings. However, ES2G-E3/52T does not specify automotive grade or AEC-Q101 qualification. Automotive applications requiring these certifications must use ES2GHE3_A/I or verify alternative part qualification with the manufacturer.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels for automated assembly equipment. Cut Tape packaging is supplied in strips cut to specified lengths for manual or semi-automated assembly. Electrical performance is identical; packaging format selection depends on assembly process requirements.

Q: Can CMR1U-04 TR13 PBFREE be used as a direct replacement for ES2GHE3_A/I?

A: CMR1U-04 TR13 PBFREE is not a direct replacement. The average rectified current rating is 1 A versus 2 A for ES2GHE3_A/I. This part is suitable only for applications with current requirements of 1 A or less. Voltage rating (400 V) and package format (DO-214AA SMB) are equivalent.

Q: What are the key electrical differences between ER2G_R1_00001 and ES2GHE3_A/I?

A: Both parts maintain 400 V reverse voltage and 2 A average rectified current. Forward voltage differs: ER2G_R1_00001 is specified at 1.25 V @ 2 A versus 1.1 V @ 2 A for ES2GHE3_A/I. Reverse leakage current is lower for ER2G_R1_00001 (1 µA @ 400 V versus 10 µA @ 50 V). Reverse recovery time is equivalent (35 ns). These differences do not preclude substitution in standard rectifier applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Q: What is the operating temperature range for each part?

A: ES2GHE3_A/I, ES2G-E3/52T, ES2G-E3/5BT, ES2G-M3/52T, and ER2G_R1_00001 operate from -55°C to 150°C junction temperature. CMR1U-04 TR13 PBFREE operates from -65°C to 175°C, providing extended low-temperature and high-temperature capability.

Q: Can packaging format be changed without affecting circuit performance?

A: Packaging format (Tape & Reel versus Cut Tape) does not affect electrical performance. Selection is determined by assembly process requirements and equipment compatibility. All DO-214AA SMB packages are mechanically and electrically equivalent.
