SS12L M2G Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS12L M2G is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for applications requiring fast recovery characteristics and low forward voltage drop. This component operates at a maximum reverse voltage of 20 V with an average rectified current rating of 1 A, making it suitable for power conversion and protection circuits in compact form factors.

The SS12L M2G maintains Active product status and is fully compliant with RoHS3 and REACH regulations. Identification of equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate packaging or inventory requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the SS12L M2G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 450 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 400 µA @ 20 V
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-219AB (Sub SMA)
• Operating Temperature - Junction: -55°C to 125°C

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all electrical parameters, maintain the same package designation, and satisfy identical regulatory compliance requirements. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical substitution eligibility.

Engineering Selection Recommendations

SS12L M2G (Primary Selection): The SS12L M2G is designated as Active product status and is the preferred selection for new circuit designs. This part maintains full compliance with current regulatory standards and is supported for ongoing production and supply continuity.

SS12L (Substitute Selection): The SS12L variant is electrically and mechanically identical to the SS12L M2G across all critical parameters. However, this part carries a "Not For New Designs" product status designation. The SS12L is suitable for replacement, repair, or legacy system applications where component compatibility with existing designs is required. The primary distinction between these parts is packaging format: SS12L M2G is supplied in standard packaging, while SS12L is available in Tape & Reel format for automated assembly processes.

Both parts satisfy identical electrical performance requirements, thermal operating ranges, and regulatory compliance obligations. Selection between these variants should be based on product lifecycle requirements and packaging format compatibility with manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the SS12L substitute for the SS12L M2G in new designs?

A: The SS12L is electrically and mechanically equivalent to the SS12L M2G. However, the SS12L carries a "Not For New Designs" product status. For new circuit designs, the SS12L M2G is the recommended selection due to its Active product status and ongoing production support.

Q: What is the difference between SS12L M2G and SS12L?

A: The electrical and mechanical specifications are identical. The primary difference is packaging format: SS12L M2G is supplied in standard packaging, while SS12L is supplied in Tape & Reel format. Additionally, SS12L M2G maintains Active product status, while SS12L is designated "Not For New Designs."

Q: Are these parts pin-compatible?

A: Both parts use the DO-219AB package (Sub SMA) with identical pinout and mechanical dimensions. They are directly interchangeable at the board level without layout modifications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: Voltage - DC Reverse (Vr) of 20 V, Current - Average Rectified (Io) of 1 A, Voltage - Forward (Vf) of 450 mV @ 1 A, Fast Recovery speed characteristics, and Reverse Leakage current of 400 µA @ 20 V. All substitute parts must maintain Schottky technology classification.

Q: Do these parts require different handling or storage procedures?

A: Both parts share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions for surface mount components apply to both variants.

Q: What is the operating temperature range for these diodes?

A: Both the SS12L M2G and SS12L operate across a junction temperature range of -55°C to 125°C, suitable for industrial and commercial applications.

Q: Are these parts RoHS and REACH compliant?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
