MA2S7280GL Equivalent & Substitute Parts

Part Overview

The MA2S7280GL is a Schottky diode manufactured by Panasonic Electronic Components, rated for 30 V DC reverse voltage and 30 mA average rectified current in a surface mount SSMini2-F4 package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MA2S7280GL are selected based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Technology: Schottky diode
• Mounting Type: Surface Mount
• Package / Case: SC-79 or SOD-523 compatible
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Current Rating Consideration: Substitute parts are grouped into two categories based on average rectified current (Io) rating:

1. Direct Current Match (30 mA): Parts rated for 30 mA average rectified current provide direct functional equivalence for applications requiring the original 30 mA specification.

2. Higher Current Rating (200 mA): Parts rated for 200 mA average rectified current exceed the original specification and are suitable for applications where increased current capacity is acceptable or beneficial, provided forward voltage characteristics remain within acceptable design margins.

All substitute parts maintain Schottky technology, 30 V reverse voltage rating, surface mount configuration, and SOD-523 package compatibility with the original component.

Engineering Selection Recommendations

RB751S40T5G (onsemi) - Primary Substitute

The RB751S40T5G provides the closest functional match to the MA2S7280GL. Both components are rated for 30 mA average rectified current at 30 V reverse voltage. The RB751S40T5G is active in production status, ROHS3 compliant, and REACH unaffected, ensuring long-term availability and regulatory compliance. The operating temperature range of -55°C to 150°C exceeds the original component's maximum junction temperature of 125°C, providing enhanced thermal margin. The SOD-523 package is directly compatible with the original SC-79/SOD-523 specification.

RB520S30T1G (onsemi) - Higher Current Alternative

The RB520S30T1G is rated for 200 mA average rectified current, exceeding the original 30 mA specification. This part is suitable for applications where increased current capacity is required or where design margins warrant higher current rating. The component is active in production, ROHS3 compliant, and REACH unaffected. The forward voltage of 600 mV at 200 mA is lower than the original specification at 30 mA, indicating improved efficiency characteristics at higher current levels.

SBAT54XV2T1G (onsemi) - Higher Current Alternative

The SBAT54XV2T1G is rated for 200 mA average rectified current and provides an alternative for applications requiring increased current capacity. This component is active in production, ROHS3 compliant, and REACH unaffected. The operating temperature range of -55°C to 125°C matches the original component's maximum junction temperature specification. The forward voltage of 800 mV at 100 mA should be evaluated against specific circuit requirements.

All substitute parts maintain the required 30 V reverse voltage rating, Schottky technology, surface mount configuration, and MSL 1 moisture sensitivity level of the original component.

Frequently Asked Questions (FAQ)

Q: Can RB520S30T1G be used as a direct replacement for MA2S7280GL?

A: RB520S30T1G is electrically compatible with MA2S7280GL in terms of voltage rating (30 V) and package type (SOD-523). However, RB520S30T1G is rated for 200 mA average rectified current compared to the original 30 mA rating. This higher current rating does not prevent substitution; it indicates the part can handle greater current loads. Forward voltage characteristics differ (600 mV @ 200 mA vs. 1 V @ 30 mA), requiring circuit-level evaluation to confirm suitability.

Q: What is the difference between RB751S40T5G and RB520S30T1G?

A: Both parts are onsemi Schottky diodes rated for 30 V reverse voltage in SOD-523 packages. RB751S40T5G is rated for 30 mA average rectified current, matching the original MA2S7280GL specification. RB520S30T1G is rated for 200 mA average rectified current. RB751S40T5G provides the closest current rating match to the original component. RB520S30T1G is suitable when higher current capacity is required.

Q: Are all substitute parts available in the same package as the original MA2S7280GL?

A: All substitute parts are available in SOD-523 package, which is compatible with the original SC-79/SOD-523 specification. The SOD-523 package is a standard surface mount package for small signal Schottky diodes and is directly compatible with the original component's footprint and mounting requirements.

Q: What is the significance of the operating temperature range difference between substitute parts?

A: The MA2S7280GL specifies a maximum junction temperature of 125°C. RB751S40T5G and RB520S30T1G both support operating temperature ranges of -55°C to 150°C, providing a 25°C margin above the original specification. SBAT54XV2T1G supports -55°C to 125°C, matching the original maximum junction temperature. All parts are suitable for the original component's thermal environment.

Q: Are all substitute parts RoHS and REACH compliant?

A: All three substitute parts (RB520S30T1G, RB751S40T5G, and SBAT54XV2T1G) are ROHS3 compliant and REACH unaffected. The original MA2S7280GL does not specify RoHS or REACH status. Substitution with these parts ensures compliance with current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the original MA2S7280GL and all substitute parts carry this MSL rating, ensuring consistent moisture sensitivity characteristics across all options.

Q: Can forward voltage differences between substitute parts affect circuit performance?

A: Forward voltage differences must be evaluated within the context of specific circuit requirements. The MA2S7280GL specifies 1 V @ 30 mA. RB751S40T5G specifies 370 mV @ 1 mA, and RB520S30T1G specifies 600 mV @ 200 mA. These differences reflect measurement conditions and current levels. Circuit designs should verify that forward voltage characteristics of selected substitute parts remain within acceptable operating margins for the intended application.
