SS24L M2G Equivalent & Substitute Parts

Part Overview

The SS24L M2G 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 40V DC reverse voltage with a 2A average rectified current rating and features fast recovery characteristics suitable for high-frequency switching applications. The part is RoHS3 compliant and carries unlimited moisture sensitivity classification.

Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when design flexibility is required within the specified electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS24L M2G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 40V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Schottky
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS3 Compliance

Allowable Parameter Variations:

• Current - Average Rectified (Io): Substitute parts must equal or exceed 2A rating
• Voltage - Forward (Vf) (Max): Substitute parts must not exceed 500 mV @ rated current
• Current - Reverse Leakage @ Vr: Substitute parts must not exceed 400 µA @ 40V
• Speed: Substitute parts must maintain Fast Recovery ≤ 500ns, > 200mA (Io)

The SS1FL4HM3/H qualifies as a substitute based on matching voltage, package, mounting type, technology, temperature range, and compliance requirements. Current rating differences are addressed in the parameter comparison table below.

Engineering Selection Recommendations

Primary Part (SS24L M2G): The SS24L M2G remains the specified component for applications requiring the full 2A average rectified current rating. This part is active in production status with RoHS3 compliance and unlimited moisture sensitivity classification, suitable for standard industrial and consumer applications.

Substitute Part (SS1FL4HM3/H): The SS1FL4HM3/H is suitable for applications where the current requirement does not exceed 1A average rectified current. This substitute offers equivalent voltage ratings, package compatibility, and thermal characteristics. The substitute includes automotive-grade qualification (AEC-Q101) and demonstrates superior reverse leakage characteristics (200 µA versus 400 µA @ 40V). Both parts maintain identical fast recovery speed specifications and operating temperature ranges.

Selection between these parts depends on circuit current requirements. Applications requiring 2A operation must use the SS24L M2G. Applications operating at 1A or below may use either part, with the SS1FL4HM3/H offering additional automotive qualification benefits.

Frequently Asked Questions (FAQ)

Q: Can the SS1FL4HM3/H replace the SS24L M2G in all applications?

A: No. The SS1FL4HM3/H is rated for 1A average rectified current, while the SS24L M2G is rated for 2A. Substitution is valid only for circuits where the actual operating current does not exceed 1A. Exceeding the 1A rating of the substitute part violates component specifications.

Q: Are the packages physically identical?

A: Both parts use the DO-219AB package format for surface mount applications. Physical dimensions and PCB footprints are compatible, allowing direct board-level substitution where electrical parameters permit.

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

A: The SS24L M2G specifies 400 µA reverse leakage at 40V, while the SS1FL4HM3/H specifies 200 µA at 40V. The substitute part exhibits lower reverse leakage, which may provide performance benefits in low-power or precision applications.

Q: Does the automotive qualification of the SS1FL4HM3/H affect its use in non-automotive applications?

A: No. Automotive qualification (AEC-Q101) represents an additional quality and reliability standard. Parts meeting automotive standards are suitable for any application, including non-automotive use.

Q: Are the forward voltage characteristics equivalent?

A: Both parts specify 500 mV maximum forward voltage at their respective rated currents (2A for SS24L M2G, 1A for SS1FL4HM3/H). Forward voltage characteristics are equivalent within their rated operating ranges.

Q: What is the moisture sensitivity classification for both parts?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS3 compliant and REACH unaffected. No regulatory or compliance barriers exist to substitution where electrical parameters permit.
