Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS210-M3/52T is determined by strict equivalence across the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Package Compatibility: Substitutes must be housed in surface mount packages compatible with DO-214AA footprints (SMB or SMA variants). Physical dimensions and land pattern compatibility determine mechanical interchangeability.

Allowable Parameter Variations:

• Voltage - Forward (Vf) (Max) @ If: Substitutes may vary within the range of 790 mV to 1.05 V @ 2 A
• Current - Reverse Leakage @ Vr: Substitutes may range from 1 µA to 300 µA @ rated voltage
• Capacitance @ Vr, F: Substitutes may vary or be unspecified
• Operating Temperature - Junction (Max): Substitutes rated to 125°C or higher are acceptable

Parameter Comparison

Engineering Selection Recommendations

SS210 (EVVO Semi): This substitute maintains electrical equivalence across all mandatory parameters: 100 V reverse voltage, 2 A average rectified current, and fast recovery switching characteristics. The forward voltage drop is lower at 850 mV compared to 1.05 V, resulting in reduced power dissipation. The part is RoHS3 compliant with MSL 1 rating. Package compatibility requires verification: the SS210 is supplied in DO-214AC (SMA) format, which differs from the DO-214AA (SMB) footprint of the main part. Physical land pattern differences may necessitate PCB layout modification. Operating temperature maximum is 125°C, which is lower than the main part's 150°C rating. Reverse leakage current is higher at 300 µA @ 100 V. This substitute is suitable for applications where lower forward voltage drop is beneficial and PCB layout can accommodate SMA package geometry.

STPS2H100U (STMicroelectronics): This substitute meets all mandatory electrical parameters: 100 V reverse voltage, 2 A average rectified current, and fast recovery switching. The forward voltage drop is lowest at 790 mV, providing superior efficiency. Reverse leakage current is lowest at 1 µA @ 100 V, indicating superior blocking characteristics. The part is housed in DO-214AA (SMB) package, matching the main part's footprint exactly. Operating temperature maximum is 175°C, exceeding the main part's 150°C rating. RoHS3 compliance and MSL 1 rating are confirmed. This substitute provides direct mechanical and electrical compatibility with no layout modifications required.

Both substitutes are Active product status with full regulatory compliance. Selection between substitutes depends on package footprint requirements and thermal performance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the SS210 (EVVO Semi) be used as a direct replacement for the SS210-M3/52T?

A: Electrical substitution is valid; the SS210 maintains 100 V reverse voltage, 2 A current rating, and fast recovery characteristics. However, mechanical substitution requires verification. The SS210 uses DO-214AC (SMA) packaging, while the main part uses DO-214AA (SMB). These packages have different footprints and land patterns. PCB layout modification is necessary for physical installation.

Q: What is the impact of lower forward voltage drop in substitute parts?

A: The STPS2H100U exhibits 790 mV forward voltage drop compared to 1.05 V in the main part. Lower forward voltage reduces power dissipation in the diode, resulting in lower junction temperature and improved thermal performance. This is beneficial in high-current or high-frequency applications where heat generation is a concern.

Q: Are there temperature rating differences between the main part and substitutes?

A: Yes. The main part (SS210-M3/52T) operates to 150°C junction temperature. The SS210 (EVVO Semi) is rated to 125°C maximum, which is 25°C lower. The STPS2H100U is rated to 175°C maximum, which is 25°C higher. Application thermal requirements determine whether these differences are acceptable.

Q: How do reverse leakage current specifications affect part selection?

A: Reverse leakage current indicates the magnitude of current flowing through the diode when reverse biased. The main part exhibits 2 µA @ 200 V. The STPS2H100U shows 1 µA @ 100 V (superior blocking). The SS210 shows 300 µA @ 100 V (higher leakage). Lower reverse leakage is preferable in precision analog circuits and low-power applications. Higher leakage may be acceptable in power conversion applications.

Q: Is the STPS2H100U a direct pin-for-pin replacement?

A: Yes. The STPS2H100U uses DO-214AA (SMB) packaging, identical to the main part. Pin configuration, footprint, and land pattern are compatible. No PCB layout modifications are required for mechanical installation.

Q: What does RoHS3 compliance mean for these parts?

A: RoHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. All three parts (main and substitutes) are RoHS3 compliant, confirming environmental and regulatory compatibility.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all three parts across the 100 V / 2 A Schottky diode category. Mechanical interchangeability depends on package selection: STPS2H100U (SMB) is directly compatible with the main part; SS210 (SMA) requires PCB modification. Thermal and leakage specifications should be verified against application requirements before final selection.
