SS24L RUG Equivalent & Substitute Parts

Part Overview

The SS24L RUG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at a maximum reverse voltage of 40 V with an average rectified current rating of 2 A, featuring fast recovery characteristics suitable for high-frequency switching applications. The part is ROHS3 compliant and maintains unlimited moisture sensitivity classification.

Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when design requirements necessitate equivalent functionality with different manufacturer specifications or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS24L RUG is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain a maximum reverse voltage (Vr) of 40 V to ensure safe operation within the same circuit topology.

Current Rating Consideration: The SS24L RUG is rated for 2 A average rectified current. Substitute parts with lower current ratings (such as 1 A) operate within reduced current capacity and must be evaluated for application-specific current demands.

Forward Voltage Characteristics: Forward voltage drop at rated current determines power dissipation and thermal performance. The SS24L RUG specifies 500 mV @ 2 A.

Recovery Speed: Fast recovery characteristics (≤ 500ns, > 200mA) are maintained across substitute selections to preserve switching performance in high-frequency applications.

Package and Mounting: Both the main part and substitute utilize DO-219AB surface mount packaging, ensuring mechanical and thermal compatibility on printed circuit boards.

Regulatory Compliance: ROHS3 compliance and unlimited moisture sensitivity classification are maintained across all substitute options.

The identified substitute part SS1FL4HM3/H meets the voltage, speed, package, and compliance requirements while operating at a reduced current rating of 1 A.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The SS24L RUG remains the specified component for applications requiring 2 A average rectified current capacity with 40 V reverse voltage rating. This part is active in production and maintains full ROHS3 compliance with unlimited moisture sensitivity classification.

Substitute Part Selection: The SS1FL4HM3/H from Vishay General Semiconductor - Diodes Division is electrically compatible for applications where the average rectified current requirement does not exceed 1 A. This substitute maintains identical reverse voltage rating, forward voltage characteristics at its rated current, fast recovery speed, and operating temperature range. The substitute carries AEC-Q101 automotive qualification and is available in higher inventory quantities.

Compliance Considerations: Both parts maintain ROHS3 compliance, unlimited moisture sensitivity classification (MSL 1), and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Current Rating Limitation: The critical distinction between the main part and substitute is the average rectified current rating. The SS1FL4HM3/H operates at 1 A maximum, compared to the SS24L RUG at 2 A. Circuit designs operating above 1 A average rectified current require the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the SS1FL4HM3/H substitute for the SS24L RUG in all applications?

A: The SS1FL4HM3/H is suitable only for applications where the average rectified current does not exceed 1 A. If your circuit requires 2 A operation, the main part SS24L RUG must be used. Both parts share identical 40 V reverse voltage rating, forward voltage characteristics at their respective rated currents, fast recovery speed, and operating temperature range.

Q: Are the package dimensions identical between these parts?

A: Both parts utilize the DO-219AB surface mount package, ensuring identical printed circuit board footprint and thermal characteristics. The mechanical compatibility is confirmed.

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

A: The SS24L RUG specifies 400 µA reverse leakage at 40 V, while the SS1FL4HM3/H specifies 200 µA at 40 V. The substitute exhibits lower reverse leakage current, which may provide improved performance in low-power applications.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant, maintain unlimited moisture sensitivity classification (MSL 1), and are REACH unaffected. The SS1FL4HM3/H carries additional AEC-Q101 automotive qualification.

Q: What is the forward voltage drop difference at rated current?

A: Both parts specify 500 mV maximum forward voltage at their respective rated currents (2 A for SS24L RUG, 1 A for SS1FL4HM3/H). Forward voltage characteristics are equivalent at their rated operating points.

Q: Are there inventory considerations for these parts?

A: The SS24L RUG has 703 pieces in stock. The SS1FL4HM3/H has 33,182 pieces available in Tape & Reel packaging, providing significantly higher inventory availability for high-volume applications.
