Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
Reverse Recovery Time (trr): 150 ns
Current - Reverse Leakage @ Vr: 5 µA @ 400 V
Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
Operating Temperature - Junction: -55°C to 150°C
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Technology: Standard
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)
REACH Status: REACH Unaffected

Substitution differences are limited to packaging format (Tape & Reel versus Cut Tape) and inventory availability. The RS2GHE3_A/I and RS2GHE3_A/H variants include automotive-grade qualification and AEC-Q101 certification, while RS2G-E3/52T and RS2G-E3/5BT maintain equivalent electrical performance without explicit automotive grading notation in the provided data.

Engineering Selection Recommendations

All four parts listed—RS2GHE3_A/I, RS2GHE3_A/H, RS2G-E3/5BT, and RS2G-E3/52T—are Active product status and maintain full electrical and mechanical equivalence. Selection between these parts is determined by application requirements and supply chain considerations:

RS2GHE3_A/I and RS2GHE3_A/H carry automotive-grade designation and AEC-Q101 qualification. These variants are appropriate for applications requiring automotive compliance or where automotive-grade certification is specified in design requirements.

RS2G-E3/5BT and RS2G-E3/52T provide equivalent electrical performance and maintain ROHS3 compliance and REACH unaffected status. These variants are suitable for general industrial and commercial applications where automotive grading is not required.

Packaging format differs between Tape & Reel (TR) format for RS2GHE3_A/I, RS2GHE3_A/H, and RS2G-E3/5BT, and Cut Tape (CT) format for RS2G-E3/52T. Selection depends on assembly equipment compatibility and procurement workflow.

All parts maintain identical compliance certifications (ROHS3, REACH Unaffected, ECCN EAR99, HTSUS 8541.10.0080) and moisture sensitivity level MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can RS2G-E3/52T be used as a direct replacement for RS2GHE3_A/I?

A: RS2G-E3/52T is electrically equivalent to RS2GHE3_A/I across all specified parameters. The primary difference is packaging format: RS2G-E3/52T is supplied in Cut Tape (CT) format while RS2GHE3_A/I is supplied in Tape & Reel (TR) format. Compatibility depends on assembly equipment capability to process Cut Tape format.

Q: What is the difference between RS2GHE3_A/I and RS2GHE3_A/H?

A: Both parts are electrically and mechanically identical. Both carry automotive-grade designation and AEC-Q101 qualification. The difference is limited to packaging format: RS2GHE3_A/I is Tape & Reel (TR) while RS2GHE3_A/H is also Tape & Reel (TR). Inventory availability differs between the two variants.

Q: Are RS2G-E3/5BT and RS2G-E3/52T suitable for automotive applications?

A: RS2G-E3/5BT and RS2G-E3/52T maintain equivalent electrical specifications and ROHS3 compliance. However, the provided data does not indicate automotive-grade designation or AEC-Q101 qualification for these variants. Applications requiring automotive certification should specify RS2GHE3_A/I or RS2GHE3_A/H.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal moisture sensitivity and does not require special moisture control during storage, handling, or assembly. Standard storage conditions are acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: All four parts—RS2GHE3_A/I, RS2GHE3_A/H, RS2G-E3/5BT, and RS2G-E3/52T—are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the DO-214AA (SMB) package?

A: DO-214AA, commonly designated SMB (Surface Mount Body), is a standardized surface mount package for rectifier diodes. All substitute parts use this identical package, ensuring mechanical and thermal compatibility with existing PCB designs and assembly processes.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: All parts maintain identical reverse recovery time (trr) of 150 ns and fast recovery speed classification (≤ 500ns, > 200mA). Electrical performance in switching applications is equivalent across all four variants.
