Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

SS210H (Taiwan Semiconductor Corporation) is the primary equivalent for SS210HR5G. Both parts share identical electrical specifications, package form factor, automotive qualification, and operating temperature range. SS210H is currently in active production status, making it the recommended direct replacement for discontinued SS210HR5G applications.

Active Substitutes with Matching Specifications:

B2100Q-13-F (Diodes Incorporated) provides equivalent 2A current rating and DO-214AA package with AEC-Q101 automotive qualification. This part exhibits superior reverse leakage characteristics (7 µA versus 100 µA) and extended lower temperature rating (-65°C minimum). Forward voltage is slightly lower (790 mV versus 850 mV), resulting in reduced power dissipation.

B2100-13-F (Diodes Incorporated) offers identical electrical performance to B2100Q-13-F with equivalent current and voltage ratings in the same package. This variant is available in Cut Tape and Digi-Reel packaging.

Alternative Substitutes (Current Rating Considerations):

CDBB2100-HF (Comchip Technology) maintains 2A current rating and DO-214AA package compatibility. Forward voltage (810 mV) and reverse leakage (500 µA) differ from the original specification but remain within acceptable ranges for most applications.

S210 (Fairchild Semiconductor) provides matching 2A current and forward voltage (850 mV) characteristics in DO-214AA package. Extended lower temperature rating (-65°C) supports broader application ranges.

Parts with Reduced Current Rating (1A):

B1100BQ-13-F and CDBB1100-HF are suitable only for applications where the circuit current requirement does not exceed 1A. These parts are not recommended as direct replacements for 2A-rated designs.

Parts with Increased Current Rating (3A, 5A):

CDBB3100-HF and CDBB5100-HF provide higher current capacity but exhibit restricted operating temperature ranges. CDBB3100-HF is limited to -40°C to 70°C, making it unsuitable for automotive applications requiring -55°C minimum operation.

Package Variant:

SS210 (EVVO Semi) uses DO-214AC (SMA) package instead of DO-214AA (SMB). Physical dimensions differ, requiring PCB layout modification. This part is suitable only when package footprint change is acceptable.

Frequently Asked Questions (FAQ)

Q: Can SS210H be used as a direct replacement for SS210HR5G?

A: Yes. SS210H is a parametric equivalent with identical voltage rating (100V), current rating (2A), forward voltage (850 mV @ 2A), package (DO-214AA), operating temperature range (-55°C to 150°C), and automotive qualification (AEC-Q101). No circuit modification is required.

Q: What is the difference between B2100-13-F and B2100Q-13-F?

A: Both parts share identical electrical specifications and package form factor. B2100Q-13-F includes AEC-Q101 automotive qualification; B2100-13-F does not. B2100Q-13-F is supplied in Tape & Reel packaging; B2100-13-F is supplied in Cut Tape and Digi-Reel formats. Selection depends on packaging requirements and automotive qualification necessity.

Q: Can B1100BQ-13-F replace SS210HR5G?

A: No. B1100BQ-13-F is rated for 1A average rectified current, while SS210HR5G is rated for 2A. Using a 1A-rated diode in a 2A application will result in component failure or thermal damage.

Q: Why does SS210 (EVVO Semi) use a different package than SS210H?

A: SS210 uses DO-214AC (SMA) package, while SS210H uses DO-214AA (SMB) package. These packages have different physical dimensions and PCB footprints. Substitution requires PCB layout modification and is not recommended for direct replacement applications.

Q: What is the significance of reverse leakage current differences between substitute parts?

A: Reverse leakage current affects power dissipation and circuit performance at elevated temperatures. SS210HR5G specifies 100 µA @ 100V. B2100Q-13-F exhibits 7 µA, resulting in lower power loss. CDBB2100-HF exhibits 500 µA, resulting in higher power loss. Selection depends on thermal budget and application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. However, only SS210H, B2100Q-13-F, and B1100BQ-13-F carry AEC-Q101 automotive qualification matching the original SS210HR5G specification.

Q: Can CDBB3100-HF or CDBB5100-HF be used in place of SS210HR5G?

A: These parts are not recommended as direct replacements. CDBB3100-HF is limited to -40°C to 70°C operating range, which does not meet the -55°C minimum requirement of automotive applications. CDBB5100-HF operates to -55°C but exhibits different forward voltage characteristics (700 mV @ 5A) and higher current rating than required, potentially causing circuit design complications.

Q: What packaging options are available for 2A, 100V Schottky diodes in DO-214AA?

A: SS210H, B2100-13-F, B2100Q-13-F, CDBB2100-HF, and S210 are all available in DO-214AA (SMB) package. B2100-13-F and B2100Q-13-F offer Cut Tape and Tape & Reel options. SS210H and B2100Q-13-F are available in Tape & Reel format. Selection depends on production volume and assembly requirements.

Q: How does forward voltage affect circuit performance?

A: Forward voltage determines voltage drop across the diode during conduction. SS210HR5G specifies 850 mV @ 2A. B2100Q-13-F specifies 790 mV @ 2A, resulting in 60 mV lower drop and reduced power dissipation. CDBB2100-HF specifies 810 mV @ 2A. Lower forward voltage is advantageous in power-sensitive applications but does not affect switching performance or circuit functionality.
