Key Parameters

Substitute Part Grouping Explanation

Substitution of the SF22GHB0G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 100 V maximum
• Current Rating: Average rectified current must equal 2 A
• Forward Voltage Drop: Maximum forward voltage at 2 A must equal 950 mV
• Recovery Characteristics: Reverse recovery time must equal 35 ns; speed classification must be Fast Recovery (≤500 ns, >200 mA)
• Leakage Current: Reverse leakage at rated voltage must equal 5 µA maximum
• Package Configuration: Must be DO-204AC (DO-15) axial through-hole mounting
• Temperature Range: Operating junction temperature range must span -55°C to 150°C
• Compliance: Must maintain Automotive grade classification and AEC-Q101 qualification
• Environmental: Must be ROHS3 compliant

Substitute parts must match all parameters listed above without deviation. No parameter relaxation or trade-off is permitted for automotive-qualified components.

Parameter Comparison

Engineering Selection Recommendations

The SF22GHA0G is a direct electrical and mechanical equivalent to the SF22GHB0G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications across all rated parameters: 100 V reverse voltage, 2 A average rectified current, 950 mV forward voltage drop at 2 A, 35 ns reverse recovery time, and 5 µA reverse leakage current.

Both parts are housed in the DO-204AC (DO-15) axial through-hole package and operate across the identical temperature range of -55°C to 150°C. Both maintain Automotive grade classification with AEC-Q101 qualification, ensuring compliance with automotive reliability and quality standards. Both are ROHS3 compliant.

The primary distinction is product status: SF22GHB0G is discontinued at DiGi Electronics, while SF22GHA0G is currently active. For applications requiring the SF22GHB0G, the SF22GHA0G provides full functional and compliance equivalence with current availability.
