Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement):

The ES2A from YAGEO and ES2AH from Taiwan Semiconductor Corporation are parametric equivalents to the ES2A R5G. Both maintain identical voltage and current ratings with the same DO-214AA (SMB) package. The ES2AH variant includes AEC-Q101 automotive qualification, providing enhanced reliability for automotive applications. Both parts carry active product status and ROHS3 compliance.

Similar Parts with Active Status:

The following parts meet all mandatory electrical and mechanical parameters while exhibiting acceptable variations:

ES2A-13-F (Diodes Incorporated): Offers improved reverse recovery time (25 ns vs. 35 ns) and lower forward voltage (920 mV vs. 950 mV). Packaged in DO-214AA (SMB) with active product status.
CSFB201-G (Comchip Technology): Provides fast recovery characteristics (35 ns) with forward voltage of 920 mV and reduced reverse leakage (5 µA). Packaged in DO-214AA (SMB) with active product status.
ES2AHE3_A/H and ES2AHE3_A/I (Vishay): Both include AEC-Q101 automotive qualification with superior reverse recovery time (20 ns) and lower forward voltage (900 mV). Packaged in DO-214AA (SMB) with active product status.
ES2AHM3/5BT (Vishay): Offers fast recovery (30 ns) with 900 mV forward voltage. Packaged in DO-214AA (SMB) with active product status.

Package Consideration:

ES2AA-13-F (Diodes Incorporated) uses DO-214AC (SMA) package instead of DO-214AA (SMB). This part is electrically equivalent but requires PCB layout modification due to different footprint dimensions. Selection of this part is appropriate only when SMA package compatibility exists in the design.

Not Recommended for Direct Substitution:

CGRB201-G exhibits forward voltage of 1.1 V at 2 A, which exceeds the main part specification of 950 mV. While within acceptable variation limits, this higher forward voltage may impact circuit performance in applications with tight voltage margin requirements. CGRB301-G is rated for 3 A current and is not suitable for 2 A applications.

Frequently Asked Questions (FAQ)

Q: Can ES2AH replace ES2A R5G directly?

A: Yes. ES2AH is a parametric equivalent with identical voltage (50 V), current (2 A), and package (DO-214AA SMB) specifications. ES2AH includes AEC-Q101 automotive qualification, making it suitable for automotive and industrial applications requiring enhanced reliability.

Q: What is the difference between ES2A-13-F and ES2A R5G?

A: Both parts meet the 50 V, 2 A, DO-214AA (SMB) requirements. ES2A-13-F exhibits lower forward voltage (920 mV vs. 950 mV) and faster reverse recovery time (25 ns vs. 35 ns), resulting in improved efficiency and reduced switching losses. ES2A-13-F is manufactured by Diodes Incorporated with active product status.

Q: Why does CGRB201-G show higher forward voltage?

A: CGRB201-G exhibits 1.1 V forward voltage at 2 A compared to the main part's 950 mV. This variation is within acceptable substitution limits but may increase power dissipation in the diode. Selection depends on circuit voltage margin requirements and thermal design constraints.

Q: Can ES2AA-13-F be used as a substitute?

A: ES2AA-13-F is electrically equivalent but uses DO-214AC (SMA) package instead of DO-214AA (SMB). Direct PCB substitution is not possible without layout modification. This part is suitable only when SMA package footprint is available in the design.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive qualification standard for discrete semiconductors. Parts carrying this qualification (ES2AH, ES2AHE3_A/H, ES2AHE3_A/I) undergo enhanced reliability testing and are suitable for automotive applications requiring higher reliability standards.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, meeting environmental and hazardous substance restrictions equivalent to the main part.

Q: What is the significance of reverse recovery time (trr)?

A: Reverse recovery time determines how quickly the diode transitions from conducting to blocking state. Lower trr values (20-25 ns) result in reduced switching losses and improved efficiency compared to higher values (35 ns). Selection depends on switching frequency and thermal design requirements.

Q: Can CGRB301-G be used instead of ES2A R5G?

A: No. CGRB301-G is rated for 3 A average rectified current, exceeding the 2 A requirement of ES2A R5G. This part is not suitable for 2 A applications and represents a different product category.

Q: What inventory status should influence part selection?

A: All listed substitute parts maintain active product status with available inventory. ES2A R5G is discontinued at DiGi Electronics, making active alternatives necessary for new designs and ongoing production requirements.
