SS24L RVG Equivalent & Substitute Parts

Part Overview

The SS24L RVG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package. This component operates at 40 V DC reverse voltage with a 2 A average rectified current rating and features fast recovery characteristics suitable for high-frequency switching applications. The part is RoHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity classification.

Substitute parts are identified to address specific application requirements including alternative packaging formats, current ratings, and thermal operating ranges while maintaining core electrical specifications within acceptable parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS24L RVG are classified based on electrical parameter compatibility and packaging format. The primary substitution criteria are:

Electrical Parameters (Must Match or Exceed):

• Voltage - DC Reverse (Vr) (Max): 40 V minimum
• Technology: Schottky diode
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• RoHS3 Compliance
• MSL 1 (Unlimited) rating

Allowable Variations:

• Current - Average Rectified (Io): Equal or greater than 2 A
• Voltage - Forward (Vf) (Max): Within acceptable forward voltage drop range
• Current - Reverse Leakage @ Vr: Lower values acceptable
• Package / Case: Alternative surface mount packages acceptable
• Operating Temperature - Junction: Extended ranges acceptable

Substitute Categories:

MFR Recommended Substitute: SS24LW (Taiwan Semiconductor Corporation) — Same manufacturer, identical electrical specifications, alternative SOD-123W package format with higher inventory availability.

Similar Substitute: SS1FL4HM3/H (Vishay General Semiconductor - Diodes Division) — Automotive-grade alternative with reduced current rating (1 A), extended temperature range (-55°C to 150°C), and DO-219AB package compatibility. Includes AEC-Q101 qualification and eSMP® series designation.

Engineering Selection Recommendations

SS24LW Selection Criteria:

The SS24LW is the manufacturer-recommended substitute for the SS24L RVG. Both parts are produced by Taiwan Semiconductor Corporation and share identical electrical specifications: 40 V reverse voltage, 2 A average rectified current, 500 mV forward voltage at 2 A, and fast recovery characteristics. The primary difference is the package format (SOD-123W versus Sub SMA DO-219AB). Selection of SS24LW is appropriate when:

• PCB layout accommodates SOD-123W package dimensions
• Higher inventory availability is required (28,347 units in stock versus 1,973 units)
• Packaging format compatibility with existing design is confirmed
• Both parts maintain identical RoHS3 compliance and MSL 1 ratings

SS1FL4HM3/H Selection Criteria:

The SS1FL4HM3/H is a similar substitute from Vishay General Semiconductor - Diodes Division, classified as an automotive-grade component with AEC-Q101 qualification. This part maintains 40 V reverse voltage and fast recovery speed specifications but operates at a reduced current rating of 1 A (versus 2 A). Selection of SS1FL4HM3/H is appropriate when:

• Application current requirements do not exceed 1 A
• Automotive-grade qualification and AEC-Q101 compliance are required
• Extended operating temperature range (-55°C to 150°C) is necessary
• DO-219AB package format is required for PCB compatibility
• Lower reverse leakage current (200 µA) is beneficial for application performance

Compliance Considerations:

All three parts maintain RoHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and EAR99 export classification. No additional compliance verification is required for direct substitution within these parameters.

Frequently Asked Questions (FAQ)

Q: Can SS24LW directly replace SS24L RVG in existing designs?

A: SS24LW is electrically equivalent to SS24L RVG with identical voltage, current, and speed specifications. Direct replacement is possible if the PCB layout accommodates the SOD-123W package format. The Sub SMA (DO-219AB) and SOD-123W packages have different physical dimensions and pin configurations, requiring PCB layout verification.

Q: What is the primary difference between SS24LW and SS24L RVG?

A: The primary difference is the package format. SS24L RVG uses DO-219AB (Sub SMA) packaging, while SS24LW uses SOD-123W packaging. Electrical specifications are identical: 40 V reverse voltage, 2 A current rating, 500 mV forward voltage at 2 A, and fast recovery characteristics.

Q: When should SS1FL4HM3/H be selected instead of SS24L RVG?

A: SS1FL4HM3/H should be selected when automotive-grade qualification (AEC-Q101) is required or when application current requirements do not exceed 1 A. This part also provides extended operating temperature range (-55°C to 150°C) and lower reverse leakage current (200 µA). The current rating of 1 A is the limiting factor for applications requiring the full 2 A capability of SS24L RVG.

Q: Are there package compatibility issues between these substitutes?

A: Yes. SS24L RVG uses DO-219AB (Sub SMA) package, SS24LW uses SOD-123W package, and SS1FL4HM3/H uses DO-219AB (SMF) package. While SS24L RVG and SS1FL4HM3/H both use DO-219AB packages, they may have different pin configurations. PCB layout and footprint verification is required before substitution.

Q: Do all three parts meet RoHS3 compliance requirements?

A: Yes. SS24L RVG, SS24LW, and SS1FL4HM3/H are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. No additional compliance documentation is required for substitution.

Q: What is the reverse leakage current difference between these parts?

A: SS24L RVG has a reverse leakage current of 400 µA @ 40 V. Both SS24LW and SS1FL4HM3/H have lower reverse leakage current of 200 µA @ 40 V. Lower reverse leakage current reduces power dissipation and improves circuit performance in applications sensitive to leakage current.

Q: Can SS1FL4HM3/H be used in applications requiring 2 A current?

A: No. SS1FL4HM3/H is rated for 1 A average rectified current, while SS24L RVG and SS24LW are rated for 2 A. Using SS1FL4HM3/H in applications requiring 2 A operation will exceed the component's current rating and result in thermal stress and potential failure.

Q: What is the forward voltage difference between SS24LW and SS24L RVG?

A: SS24L RVG has a maximum forward voltage of 500 mV @ 2 A, while SS24LW has a maximum forward voltage of 550 mV @ 2 A. This 50 mV difference is within acceptable tolerance for most applications but should be considered in power dissipation calculations for high-current applications.
