Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RB160SS-30T2R are selected based on the following critical parameters that determine functional compatibility:

Primary Selection Criteria:

• Technology: Schottky diode
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 30 V
• Current - Average Rectified (Io): Equal to or greater than 1 A
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery or equivalent
• RoHS Compliance: ROHS3 Compliant

Secondary Considerations:

• Operating Temperature - Junction capability
• Forward voltage characteristics
• Reverse leakage current specifications
• Package form factor compatibility with PCB layout constraints

The identified substitute parts maintain the core electrical specifications required for Schottky rectifier applications while accommodating variations in package geometry and manufacturing status.

Engineering Selection Recommendations

RB160VAM-40TR (Rohm Semiconductor)

The RB160VAM-40TR is the primary substitute for the RB160SS-30T2R. Both components share the same base product number (RB160) and are manufactured by Rohm Semiconductor. The RB160VAM-40TR features a higher reverse voltage rating (40 V versus 30 V), providing enhanced voltage margin in applications. Current rating remains at 1 A, matching the original specification. Fast recovery speed characteristics are maintained. The RB160VAM-40TR holds active product status with ROHS3 compliance and unlimited moisture sensitivity level. Package geometry differs (2-SMD Flat Lead versus 0603), requiring PCB layout verification. This substitute is suitable for direct functional replacement in applications where the higher voltage rating does not create design conflicts.

BAS385-TR3 (Vishay General Semiconductor - Diodes Division)

The BAS385-TR3 is an alternative substitute with identical 30 V reverse voltage rating and ROHS3 compliance. This component is manufactured by Vishay and maintains active product status. The current rating is reduced to 200 mA, limiting applicability to circuits requiring less than 1 A average rectified current. Forward voltage is higher at 800 mV @ 100 mA. Reverse leakage current is significantly lower at 2.3 µA @ 25 V. Operating temperature maximum is 125°C, lower than the original 150°C specification. The MicroMELF package (2-SMD, No Lead) differs from the original 0603 form factor. This substitute is applicable only in applications with current requirements not exceeding 200 mA and where the reduced junction temperature rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the RB160VAM-40TR directly replace the RB160SS-30T2R without circuit modification?

A: The RB160VAM-40TR provides functional electrical compatibility as a Schottky diode with matching 1 A current rating and fast recovery speed. The higher 40 V reverse voltage rating is backward compatible with 30 V applications. However, package geometry differs (2-SMD Flat Lead versus 0603), requiring PCB footprint verification and potential layout adjustment.

Q: What are the limitations of using BAS385-TR3 as a substitute?

A: The BAS385-TR3 has a reduced current rating of 200 mA, making it unsuitable for applications requiring the full 1 A specification. The operating temperature maximum is 125°C compared to 150°C for the original part. Forward voltage is elevated at 800 mV @ 100 mA. This substitute is limited to low-current rectifier applications only.

Q: Are both substitute parts RoHS compliant?

A: Yes, both RB160VAM-40TR and BAS385-TR3 are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance status of the RB160SS-30T2R.

Q: How do package differences affect PCB design?

A: The RB160SS-30T2R uses a 0603 (1608 Metric) package. The RB160VAM-40TR uses a 2-SMD Flat Lead package, and the BAS385-TR3 uses a MicroMELF (2-SMD, No Lead) package. Each package has different footprint dimensions and land patterns. PCB layout must be verified against the specific package datasheet before implementation.

Q: What is the significance of the "Fast Recovery" speed specification?

A: Fast recovery speed (≤ 500ns for currents > 200mA) indicates the diode's switching characteristics. Both the RB160SS-30T2R and RB160VAM-40TR maintain this specification, ensuring compatibility in high-frequency rectification circuits. The BAS385-TR3 is classified as small signal with any speed, indicating different switching behavior suitable only for lower-current applications.

Q: Why is the RB160SS-30T2R classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Rohm Semiconductor. The RB160VAM-40TR, sharing the same base product number, represents the active continuation of this product line and is the recommended substitute for new designs and ongoing procurement.

Q: Can reverse leakage current differences affect circuit performance?

A: Reverse leakage current specifications vary among the substitutes. The RB160SS-30T2R specifies 35 µA @ 30 V, the RB160VAM-40TR specifies 50 µA @ 40 V, and the BAS385-TR3 specifies 2.3 µA @ 25 V. In applications sensitive to leakage current, such as precision analog circuits, these differences must be evaluated against circuit requirements.
