Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS32 V7G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• Operating Temperature Range: Minimum -55°C to maximum ≥ 125°C
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Package Compatibility: Substitute parts must use either DO-214AB (SMC) or DO-214AC (SMA) surface mount packages. These packages are mechanically and electrically compatible for PCB assembly applications.

Acceptable Parameter Variations:

• Current - Reverse Leakage @ Vr: Specified values between 500 µA and 1.5 mA @ 20 V are acceptable
• Voltage - Forward (Vf) (Max) @ If: When specified, values between 460 mV and 500 mV @ 3 A are acceptable
• Operating Temperature - Junction: Upper limit may extend to 150°C without affecting substitution validity

Engineering Selection Recommendations

Direct Equivalent - SS32 (MDD): The SS32 manufactured by MDD is a direct equivalent with identical electrical specifications and active product status. This part is available in high inventory (19566 units) and maintains all compliance certifications. The only mechanical difference is the package designation (DO-214AC, SMA versus DO-214AB, SMC), which represents a compatible surface mount variant. This part is the primary recommendation for replacement applications.

Functional Equivalent - 5820SMJE3/TR13 (Microchip Technology): The 5820SMJE3/TR13 meets all mandatory electrical parameters with active product status and ROHS3 compliance. This part is supplied in Tape & Reel packaging and features an extended operating temperature range to 150°C. The reverse leakage current specification (1.5 mA @ 20 V) is within acceptable limits. This part is suitable for applications requiring higher temperature operation or tape-and-reel packaging format.

Functional Equivalent - SS32-M3/9AT (Vishay General Semiconductor - Diodes Division): The SS32-M3/9AT is functionally equivalent with matching electrical specifications and active product status. This part is supplied in Tape & Reel packaging and maintains identical reverse leakage current (500 µA @ 20 V) and operating temperature range. All compliance certifications are maintained. This part is suitable for high-volume production requiring tape-and-reel format.

Selection Criteria:

• For standard applications with standard packaging requirements: SS32 (MDD)
• For applications requiring extended temperature operation: 5820SMJE3/TR13 (Microchip Technology)
• For high-volume production with tape-and-reel requirements: SS32-M3/9AT (Vishay)

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory and environmental compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SS32 (MDD) be used as a direct replacement for the SS32 V7G?

A: Yes. The SS32 (MDD) is a direct functional equivalent. Both parts share identical electrical specifications: 20 V reverse voltage, 3 A average rectified current, fast recovery Schottky technology, and -55°C to 125°C operating temperature range. The package designation difference (DO-214AC, SMA versus DO-214AB, SMC) represents compatible surface mount variants suitable for the same PCB assembly processes.

Q: What is the difference between the DO-214AB (SMC) and DO-214AC (SMA) packages?

A: Both packages are surface mount Schottky diode packages with identical electrical performance and pin configurations. DO-214AB (SMC) and DO-214AC (SMA) are mechanically compatible variants used interchangeably in surface mount assembly. Component placement and soldering processes are identical.

Q: Why does the 5820SMJE3/TR13 have a higher reverse leakage current specification?

A: The 5820SMJE3/TR13 specifies 1.5 mA @ 20 V reverse leakage current compared to 500 µA @ 20 V for the SS32 V7G. This variation remains within acceptable limits for Schottky diode technology and does not affect functional substitution. The higher leakage specification reflects manufacturing process differences between Microchip Technology and Taiwan Semiconductor Corporation while maintaining equivalent circuit performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SS32 by MDD, 5820SMJE3/TR13 by Microchip Technology, and SS32-M3/9AT by Vishay) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH unaffected status. Regulatory and environmental compliance is maintained across all substitutes.

Q: What packaging format should I select for high-volume production?

A: For high-volume production, select either the 5820SMJE3/TR13 (Microchip Technology) or SS32-M3/9AT (Vishay), both supplied in Tape & Reel (TR) format. Tape and reel packaging is optimized for automated pick-and-place assembly processes. The SS32 (MDD) is available in standard packaging format suitable for lower-volume or manual assembly applications.

Q: Can the SS32-M3/9AT be used in applications requiring extended temperature operation?

A: The SS32-M3/9AT operates within -55°C to 125°C, matching the SS32 V7G specification. For applications requiring extended temperature operation above 125°C, the 5820SMJE3/TR13 (Microchip Technology) extends to 150°C maximum junction temperature while maintaining all other electrical specifications.

Q: Are there any electrical performance differences between the substitute parts?

A: All substitute parts maintain identical voltage and current ratings (20 V, 3 A). Forward voltage specifications vary slightly where provided: 460 mV @ 3 A (Microchip) and 500 mV @ 3 A (Vishay) versus unspecified for the original part. Reverse leakage current ranges from 500 µA to 1.5 mA @ 20 V across all parts. These variations are within normal manufacturing tolerances for Schottky diode technology and do not affect functional substitution.
