SS115L RQG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS115L RQG 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 with unlimited moisture sensitivity level (MSL 1).

The SS115L RQG serves in applications requiring fast recovery rectification in compact surface mount packages. Identification of equivalent and substitute parts is necessary to support procurement flexibility, manage supply chain continuity, and accommodate design revisions where alternative packaging or inventory configurations are required.

Substitute Part Grouping Explanation

Substitution of the SS115L RQG is determined by electrical and mechanical parameter equivalence within the Schottky diode rectifier category. The critical parameters that define substitutability are:

Electrical Parameters:

• 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:

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

Substitute parts must match all electrical parameters and the DO-219AB package specification. Packaging configuration (Tape & Reel versus other formats) does not affect electrical substitutability but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

The SS115L (Tape & Reel configuration) is electrically and mechanically equivalent to the SS115L RQG. Both parts are manufactured by Taiwan Semiconductor Corporation and meet identical electrical specifications for 150 V reverse voltage, 1 A rectified current, and fast recovery Schottky performance.

Product Status Consideration: The substitute part SS115L carries a "Not For New Designs" status, indicating it is in mature or declining production phase. For new circuit designs, the SS115L RQG (Active status) is the preferred selection. The SS115L substitute is suitable for replacement, repair, and legacy system support where the part is already in use.

Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). No compliance barriers exist between the main part and substitute.

Packaging Consideration: The primary difference is packaging configuration. The SS115L RQG is supplied in bulk format, while the SS115L substitute is supplied in Tape & Reel (TR) format. This distinction affects procurement quantity, storage, and automated assembly compatibility but does not alter electrical performance or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SS115L (Tape & Reel) be used as a direct replacement for the SS115L RQG?

A: Yes. Both parts are electrically and mechanically identical. They share the same DO-219AB package, electrical ratings (150 V, 1 A, 900 mV forward voltage), and operating temperature range (-55°C to 150°C). The difference is packaging format: Tape & Reel versus bulk. Direct substitution is valid for circuit performance.

Q: What does "Not For New Designs" status mean for the SS115L substitute?

A: This status indicates the part is in mature production phase and may have limited future availability. For new circuit designs, Taiwan Semiconductor Corporation recommends using the SS115L RQG (Active status). The "Not For New Designs" part remains suitable for replacement and repair of existing systems.

Q: Are there any compliance differences between the main part and substitute?

A: No. Both the SS115L RQG and SS115L substitute are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). Compliance certifications are identical.

Q: Does Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a packaging and delivery format used for automated assembly. It does not affect the electrical characteristics, performance, or reliability of the diode itself. The component inside the Tape & Reel package is identical to the bulk-packaged version.

Q: What are the key electrical parameters that define substitutability for this Schottky diode?

A: Substitutability is determined by: Voltage - DC Reverse (Vr) of 150 V, Current - Average Rectified (Io) of 1 A, Voltage - Forward (Vf) of 900 mV @ 1 A, Fast Recovery speed (≤ 500ns), Current - Reverse Leakage of 50 µA @ 150 V, and Operating Temperature range of -55°C to 150°C. All substitute parts must match these specifications and the DO-219AB package.

Q: Can I use this diode in high-frequency switching applications?

A: The SS115L RQG and its substitute are specified for fast recovery operation (≤ 500ns, > 200mA). This performance characteristic supports switching applications within the rated voltage and current limits. Specific application suitability depends on circuit design requirements beyond the scope of this substitution reference.
