SS115L Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS115L is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 150 V DC reverse voltage and 1 A average rectified current. This component is classified as Active product status and is RoHS3 compliant. The SS115L serves in applications requiring fast recovery rectification with low forward voltage drop characteristics typical of Schottky technology.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when alternative packaging configurations are required to meet procurement or manufacturing specifications. The SS115L remains available in multiple packaging formats that maintain electrical and mechanical compatibility while offering different supply chain options.

Substitute Part Grouping Explanation

Substitution of the SS115L is determined by strict equivalence across all critical electrical parameters and mechanical specifications. The following parameters establish the substitution criteria:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 150 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Parameters (Must Match Exactly):

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

Substitute parts identified within the SS115L family maintain identical electrical performance and mechanical compatibility. Packaging format variations (such as Tape & Reel versus individual units) do not affect electrical or functional equivalence and represent alternative supply configurations of the same component specification.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status: The SS115L (MTG) maintains Active product status and is the primary selection for new designs and ongoing production applications. This variant is recommended for all new circuit implementations and long-term supply chain planning.

Alternative Packaging Configuration: The SS115L (TR) variant is supplied in Tape & Reel packaging format and carries Not For New Designs status. This configuration is electrically and mechanically identical to the primary part but is designated for legacy support, replacement inventory, or high-volume automated assembly operations where tape-and-reel format is required.

Compliance Assurance: Both variants maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and storage conditions without special handling requirements.

Supply Chain Considerations: Selection between variants depends on procurement requirements and manufacturing process specifications. The Active status of SS115L (MTG) ensures continued availability and manufacturer support for new applications.

Frequently Asked Questions (FAQ)

Q: Can the SS115L (TR) tape and reel variant be used as a direct substitute for the SS115L (MTG) individual unit packaging?

A: Yes. Both variants are electrically and mechanically identical. The difference is packaging format only. The SS115L (TR) is supplied in Tape & Reel configuration suitable for automated pick-and-place assembly, while SS115L (MTG) is supplied as individual units. Electrical performance, thermal characteristics, and reliability are identical.

Q: What does "Not For New Designs" status mean for the SS115L (TR) variant?

A: This designation indicates that while the part remains available and functional, the manufacturer recommends using the Active status variant (SS115L MTG) for new circuit designs. The Not For New Designs status does not affect electrical performance or reliability; it reflects manufacturer lifecycle management and supply planning.

Q: Are there any differences in RoHS compliance or moisture sensitivity between the two SS115L variants?

A: No. Both variants are ROHS3 compliant and carry MSL Level 1 (Unlimited) rating. Moisture sensitivity handling and storage requirements are identical for both packaging formats.

Q: What are the critical electrical parameters that define SS115L substitution compatibility?

A: Substitutes must maintain exact equivalence in: 150 V DC reverse voltage rating, 1 A average rectified current, 900 mV maximum forward voltage at 1 A, fast recovery speed characteristic (≤ 500ns), 50 µA reverse leakage current at 150 V, and -55°C to 150°C operating temperature range.

Q: Can the SS115L be used in applications requiring different voltage or current ratings?

A: No. The SS115L is rated specifically for 150 V reverse voltage and 1 A average rectified current. Applications with different voltage or current requirements require alternative diode part numbers with appropriate ratings.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the standardized package outline for Sub SMA surface mount Schottky diodes. This package designation ensures mechanical compatibility with standard PCB footprints and automated assembly equipment. Both SS115L variants use this identical package.

Q: Is the SS115L suitable for high-frequency switching applications?

A: The SS115L incorporates fast recovery Schottky technology with recovery time ≤ 500ns at currents > 200mA, making it suitable for switching applications within its current and voltage ratings. Specific application suitability depends on circuit frequency requirements and thermal management design.
