Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Replacement):

The ES2BH manufactured by Taiwan Semiconductor Corporation is the primary recommended equivalent. This part maintains identical electrical specifications to the ES2BHR5G (100 V, 2 A, 950 mV forward voltage, 35 ns reverse recovery time) and carries the same AEC-Q101 automotive qualification. The ES2BH is currently active in production, ensuring supply continuity. The ES2B from YAGEO provides an alternative parametric equivalent with active product status and identical voltage and current ratings.

Active Substitute Selection (Functional Compatibility):

For applications where forward voltage and reverse leakage variations are acceptable, the following active parts provide functional substitution:

ES2B-13-F (Diodes Incorporated): Maintains 100 V / 2 A specifications with 920 mV forward voltage and 25 ns reverse recovery time. Operating temperature range matches the main part (-55°C to 150°C).
CSFB202-G (Comchip Technology): Provides 100 V / 2 A operation with 920 mV forward voltage and 35 ns reverse recovery time. Lower reverse leakage (5 µA) compared to the main part.
ESH2B-E3/5BT and ESH2B-E3/52T (Vishay General Semiconductor - Diodes Division): Both maintain 100 V / 2 A specifications with 930 mV forward voltage and 35 ns reverse recovery time. Extended operating temperature range (-55°C to 175°C) provides additional thermal margin. Reverse leakage is 2 µA, lower than the main part.

Compliance Verification:

All recommended equivalents and substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the ES2BHR5G.

Parts Not Recommended for Direct Replacement:

ER1B-LTP (Micro Commercial Co): Current rating of 1 A is insufficient for 2 A applications. Product status is "Not For New Designs."
ES2BA-13-F (Diodes Incorporated): Package is DO-214AC (SMA), not DO-214AA (SMB). Mechanical incompatibility with existing PCB layouts designed for SMB packages.
CGRB202-G (Comchip Technology): Forward voltage of 1.1 V at 2 A exceeds the 950 mV specification of the main part, introducing potential circuit performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ES2BH be used as a direct replacement for ES2BHR5G?

A: Yes. The ES2BH is a parametric equivalent with identical electrical specifications (100 V, 2 A, 950 mV forward voltage, 35 ns reverse recovery time) and the same AEC-Q101 automotive qualification. Both use the DO-214AA (SMB) package. The ES2BH is currently in active production.

Q: What is the difference between "Parametric Equivalent" and "Similar" classifications?

A: Parametric Equivalent parts match all critical electrical specifications of the main part within stated tolerances. Similar parts meet the primary voltage and current requirements but may differ in secondary parameters such as forward voltage, reverse leakage, or reverse recovery time. Similar parts remain functionally compatible for general-purpose rectification but may produce different circuit behavior in applications sensitive to these variations.

Q: Can ES2BA-13-F replace ES2BHR5G?

A: No. Although ES2BA-13-F matches the electrical specifications (100 V, 2 A), it uses a DO-214AC (SMA) package instead of the DO-214AA (SMB) package of the main part. The different package footprint is mechanically incompatible with PCB layouts designed for SMB components.

Q: Why is ER1B-LTP not recommended as a substitute?

A: The ER1B-LTP is rated for 1 A average rectified current, which is insufficient for applications requiring 2 A operation. Additionally, this part is marked "Not For New Designs," indicating end-of-life status. It is not suitable for new production designs.

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

A: Reverse recovery time affects switching speed and switching losses in rectification circuits. The ES2BHR5G specifies 35 ns. Substitutes with equal or faster recovery times (such as ES2B-13-F at 25 ns) are compatible. Slower recovery times may increase switching losses and heat generation.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. All parametric equivalents and active substitutes listed in this document are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the ES2BHR5G.

Q: What is the impact of forward voltage differences between substitutes?

A: Forward voltage affects power dissipation and voltage drop across the diode during conduction. The ES2BHR5G specifies 950 mV at 2 A. Substitutes with lower forward voltage (such as 920 mV or 930 mV) reduce power dissipation and heat generation. Substitutes with higher forward voltage (such as 1.1 V) increase power dissipation. Selection depends on circuit thermal design and voltage regulation requirements.

Q: Can ESH2B-E3/5BT be used in automotive applications?

A: The ESH2B-E3/5BT is not explicitly qualified to AEC-Q101 in the provided specifications, unlike the ES2BHR5G. For automotive applications requiring AEC-Q101 qualification, the ES2BH is the recommended choice. For non-automotive applications, ESH2B-E3/5BT provides functional equivalence with extended operating temperature range (-55°C to 175°C).

Q: What packaging options are available for 100 V / 2 A rectifier diodes?

A: The primary package for these specifications is DO-214AA (SMB), used by ES2BHR5G, ES2BH, ES2B-13-F, CSFB202-G, CGRB202-G, ESH2B-E3/5BT, and ESH2B-E3/52T. An alternative package is DO-214AC (SMA), used by ES2BA-13-F. Package selection depends on PCB layout requirements and available board space.

Q: Is the YAGEO ES2B suitable for high-volume production?

A: Yes. The YAGEO ES2B is marked as "Active" with 55,400 pieces in stock, indicating strong supply availability and suitability for high-volume production requirements.
