Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents):

SS210H from Taiwan Semiconductor Corporation is the primary direct replacement. This part maintains identical electrical specifications (100V, 2A, 850 mV forward voltage) and DO-214AA packaging. The part is currently active in production and carries AEC-Q101 automotive qualification, providing enhanced reliability documentation. Operating temperature range matches the original (-55°C to 150°C).

Alternative Equivalent (Different Manufacturer):

SS210-M3/52T from Vishay General Semiconductor - Diodes Division provides equivalent voltage and current ratings in identical DO-214AA packaging. Forward voltage is specified at 1.05V @ 2A, representing a 200mV increase over the original specification. Reverse leakage is significantly lower at 2µA @ 200V. This part is suitable for applications where lower leakage current provides design benefit and forward voltage increase is acceptable.

Functional Equivalents (Same Voltage and Current, Active Status):

B2100-13-F and B2100Q-13-F from Diodes Incorporated both provide 100V, 2A ratings in DO-214AA packaging. Forward voltage is 790 mV @ 2A, representing a 60mV improvement over the original. B2100Q-13-F carries AEC-Q101 automotive qualification. Operating temperature extends to -65°C minimum. Both parts are currently in active production.

CDBB2100-HF from Comchip Technology provides 100V, 2A in DO-214AA packaging with 810 mV forward voltage. Operating temperature minimum is -50°C. This part is currently active.

Current Derating Alternatives:

B1100BQ-13-F and CDBB1100-HF are 1A rated devices at 100V in DO-214AA packaging. These are suitable only for applications where circuit design permits operation at reduced current capacity.

Current Upgrading Alternatives:

CDBB3100-HF (3A) and CDBB5100-HF (5A) provide higher current capacity at 100V in DO-214AA packaging. CDBB3100-HF operating temperature is limited to -40°C to 70°C. CDBB5100-HF operates -55°C to 125°C. These are suitable for applications requiring higher current handling.

Frequently Asked Questions (FAQ)

Q: Can SS210H be used as a direct replacement for SS210 R5G?

A: Yes. SS210H from Taiwan Semiconductor Corporation provides identical electrical specifications (100V, 2A, 850 mV forward voltage) and DO-214AA packaging. The part is currently in active production status, unlike the discontinued SS210 R5G. Operating temperature range is identical (-55°C to 150°C).

Q: What is the difference between DO-214AA and SMA packaging?

A: DO-214AA and SMA are distinct package designations for surface mount diodes. The SS210 from EVVO Semi uses DO-214AC (SMA) packaging, which differs mechanically from the DO-214AA (SMB) package of the original SS210 R5G. These packages are not interchangeable on the same PCB layout without design modification.

Q: Can I use a 1A rated diode (B1100BQ-13-F or CDBB1100-HF) in place of the 2A SS210 R5G?

A: Only if circuit design analysis confirms that actual operating current does not exceed 1A. The 1A rating represents the maximum average rectified current specification. Using a lower-rated device in a 2A application will result in device failure or reduced reliability.

Q: What is the significance of forward voltage differences between substitute parts?

A: Forward voltage (Vf) affects power dissipation and voltage drop across the diode. The original SS210 R5G specifies 850 mV @ 2A. Alternatives range from 790 mV (B2100 series) to 1.05 V (SS210-M3/52T). Lower forward voltage reduces power loss; higher forward voltage increases it. Circuit design must accommodate the selected part's forward voltage specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, matching the original SS210 R5G environmental compliance status.

Q: What does AEC-Q101 qualification indicate?

A: AEC-Q101 is an automotive electronics qualification standard. Parts carrying this qualification (SS210H, B2100Q-13-F) have undergone additional reliability testing and documentation suitable for automotive applications. This qualification is optional for non-automotive applications but indicates enhanced quality assurance.

Q: Can I use CDBB5100-HF (5A) in a circuit designed for SS210 R5G (2A)?

A: Yes, from a current capacity perspective. The 5A rating indicates the device can safely handle higher current. However, the operating temperature range is limited to -55°C to 125°C (versus -55°C to 150°C for the original). Verify that this temperature limitation does not conflict with application requirements.

Q: What is the difference between reverse leakage current specifications?

A: Reverse leakage current (Ir) represents the small current flowing through the diode when reverse biased. The original SS210 R5G specifies 100 µA @ 100V. Alternatives range from 2 µA (SS210-M3/52T) to 500 µA (Comchip and Diodes Inc. parts). Lower leakage current reduces standby power consumption and heat generation. Higher leakage current increases these factors. Circuit design must accommodate the selected part's leakage specification.

Q: Is the SS210 from EVVO Semi a suitable replacement?

A: The EVVO Semi SS210 provides identical electrical specifications (100V, 2A, 850 mV forward voltage) but uses DO-214AC (SMA) packaging instead of DO-214AA (SMB). This package difference requires PCB layout modification and is not a direct mechanical replacement. Operating temperature range is also reduced to -55°C to 125°C.
