SS115L RFG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS115L RFG 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 150 V DC reverse voltage with 1 A average rectified current capacity. The part is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Identification of equivalent and substitute parts becomes necessary when the primary part number is unavailable, when inventory constraints exist, or when alternative packaging formats are required for manufacturing processes. The SS115L RFG is available in limited quantities; therefore, understanding compatible alternatives ensures design continuity and supply chain flexibility.

Substitute Part Grouping Explanation

Substitution of the SS115L RFG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• 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
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part SS115L (Tape & Reel packaging variant) meets all electrical, mechanical, and compliance requirements. This part is electrically identical to the SS115L RFG but differs in packaging format (Tape & Reel versus individual packaging) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (SS115L RFG): The SS115L RFG is the recommended choice for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. It is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The individual packaging format supports flexible procurement and prototyping workflows.

Alternative Selection (SS115L - Tape & Reel): The SS115L in Tape & Reel packaging is electrically and mechanically equivalent to the SS115L RFG. This variant is suitable for high-volume manufacturing processes that require automated tape-and-reel component feeding. However, this part carries "Not For New Designs" product status, indicating the manufacturer has transitioned away from active development and support. Selection of this variant is appropriate only when existing manufacturing infrastructure is optimized for tape-and-reel formats and when inventory availability of the primary part is insufficient.

Compliance Considerations: Both parts maintain identical RoHS3 compliance and REACH unaffected status. No additional regulatory review is required when substituting between these variants.

Frequently Asked Questions (FAQ)

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

A: Yes. The SS115L in Tape & Reel packaging is electrically and mechanically identical to the SS115L RFG. Both parts share identical electrical specifications (150 V reverse voltage, 1 A average rectified current, 900 mV forward voltage drop), the same DO-219AB package, and identical operating temperature range (-55°C to 150°C). The only differences are packaging format and product status classification.

Q: What is the significance of the "Not For New Designs" status on the SS115L substitute?

A: "Not For New Designs" indicates that the manufacturer has discontinued active development and support for this product variant. While the part remains functionally equivalent and available in inventory, it is not recommended for new circuit designs. This classification reflects the manufacturer's product lifecycle management and does not indicate a technical deficiency.

Q: Are there any compatibility issues when switching from individual packaging to Tape & Reel format?

A: No compatibility issues exist at the component level. Both packaging formats contain the identical die and lead configuration. The difference is purely in the delivery and handling format. Tape & Reel packaging is optimized for automated pick-and-place assembly equipment, while individual packaging supports manual assembly and prototyping. Circuit performance and electrical characteristics remain unchanged.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both the SS115L RFG and SS115L (Tape & Reel) are RoHS3 compliant and REACH unaffected. No additional compliance review or certification is required when substituting between these variants.

Q: What is the base product number for these parts?

A: The base product number is SS115. Both the SS115L RFG and SS115L variants are derived from this base designation, with the "L" suffix indicating the specific electrical rating (150 V, 1 A).

Q: How do the reverse leakage current specifications compare?

A: Both parts specify identical reverse leakage current of 50 µA at 150 V DC reverse voltage. This parameter is critical for low-power applications and is guaranteed to be equivalent across both variants.

Q: Is the fast recovery speed specification identical between both parts?

A: Yes. Both parts meet the fast recovery specification of ≤ 500 ns for currents greater than 200 mA. This parameter determines switching performance in high-frequency rectification applications and is identical across both variants.
