SS16L RTG Equivalent & Substitute Parts

Part Overview

The SS16L RTG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 60 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or alternative sourcing is required for supply chain continuity. The SS16L RTG maintains parametric equivalence with select alternative part numbers that share identical electrical ratings and mechanical compatibility within the DO-219AB package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS16L RTG is determined by strict parametric matching across the following critical criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 700 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA or DO-219AB (SMF)

Compliance Parameters (Must Match or Exceed):

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

Parts are grouped into two categories:

Parametric Equivalent: SS16L R3G shares identical electrical and mechanical specifications with the main part. This part is discontinued at DiGi Electronics but maintains full parameter compatibility.

Similar Manufacturer Parts: SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are manufactured by Vishay General Semiconductor - Diodes Division. These parts maintain the same package, voltage rating, and mounting type. Specific differences in current rating and reverse leakage characteristics are noted in the parameter comparison table.

Engineering Selection Recommendations

SS16L R3G (Parametric Equivalent): This part maintains complete electrical and thermal equivalence to the SS16L RTG with identical voltage, current, and forward voltage specifications. Both parts share the same manufacturer base product number (SS16) and package designation. The SS16L R3G is discontinued at DiGi Electronics but remains available through alternative distribution channels. Selection of this part is appropriate when supply continuity from the original manufacturer is prioritized and inventory availability permits.

SS1FH6-M3/H (Vishay General Semiconductor): This part is electrically equivalent at the 1 A current rating with matching 60 V reverse voltage and 700 mV forward voltage specifications. The Vishay part exhibits superior reverse leakage characteristics (3 µA versus 400 µA) and extended operating temperature range (-55 to 175°C versus -55 to 150°C). This part is Active status with high inventory availability. Selection is appropriate for applications where lower leakage current and extended temperature operation provide system benefits.

SS1FH6HM3/H (Vishay General Semiconductor - Automotive Grade): This part is electrically equivalent to SS1FH6-M3/H with the addition of automotive-grade qualification (AEC-Q101). All electrical parameters, package specifications, and compliance certifications match the main part. Selection is required for automotive applications or systems requiring AEC-Q101 certification.

SS2FH6HM3/H (Vishay General Semiconductor - Automotive Grade, 2 A Rating): This part shares the same 60 V reverse voltage rating and DO-219AB package but is rated for 2 A average rectified current with corresponding forward voltage of 780 mV @ 2 A. This part includes automotive-grade qualification (AEC-Q101). Selection is appropriate only when the application circuit is designed for 2 A operation and automotive qualification is required. This part is not a direct substitute for 1 A applications.

Frequently Asked Questions (FAQ)

Q: Can SS16L R3G be used as a direct replacement for SS16L RTG?

A: Yes. The SS16L R3G is a parametric equivalent with identical voltage rating (60 V), current rating (1 A), forward voltage (700 mV @ 1 A), and package specification (DO-219AB Sub SMA). Both parts share the same base product number (SS16) and RoHS3 compliance status. The primary consideration is product status: SS16L R3G is discontinued at DiGi Electronics, requiring verification of alternative distribution availability.

Q: What is the difference between the Taiwan Semiconductor Corporation parts and Vishay parts?

A: The primary electrical difference is reverse leakage current. Taiwan Semiconductor Corporation parts (SS16L RTG and SS16L R3G) specify 400 µA @ 60 V, while Vishay parts specify 3 µA @ 60 V. Vishay parts also offer extended operating temperature range (-55 to 175°C versus -55 to 150°C). Both manufacturers provide RoHS3 compliance and MSL 1 rating. Vishay parts are Active status with higher inventory availability.

Q: Can SS2FH6HM3/H replace SS16L RTG in a 1 A application?

A: No. While SS2FH6HM3/H shares the same 60 V reverse voltage rating and DO-219AB package, it is rated for 2 A average rectified current. Using a 2 A-rated diode in a 1 A application is not a direct substitution and may result in circuit behavior changes due to different forward voltage characteristics (780 mV @ 2 A versus 700 mV @ 1 A). Selection of SS2FH6HM3/H is appropriate only when the application circuit is designed for 2 A operation.

Q: Are Vishay automotive-grade parts (SS1FH6HM3/H and SS2FH6HM3/H) required for non-automotive applications?

A: No. Automotive-grade qualification (AEC-Q101) is not required for non-automotive applications. For non-automotive use, SS1FH6-M3/H provides equivalent electrical performance without automotive-grade designation. Selection of automotive-grade parts is necessary only when the application or system specification explicitly requires AEC-Q101 certification.

Q: What is the significance of the reverse leakage current difference between manufacturers?

A: Reverse leakage current (400 µA for Taiwan Semiconductor Corporation versus 3 µA for Vishay) affects power dissipation and circuit performance in high-impedance or precision applications. The lower leakage of Vishay parts reduces standby power consumption and heat generation. For standard rectification applications, both specifications are within acceptable operating parameters. Applications with strict power budget requirements should consider the lower leakage characteristic of Vishay parts.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts use the DO-219AB package with Sub SMA or DO-219AB (SMF) supplier designation. This package family maintains identical mechanical dimensions and PCB footprint compatibility. Surface mount assembly processes and reflow profiles remain unchanged across all substitute parts.

Q: What is the inventory status for each substitute part?

A: SS16L RTG: 695 Pcs. SS16L R3G: 2463 Pcs (discontinued at DiGi Electronics). SS1FH6-M3/H: 360,400 Pcs. SS1FH6HM3/H: 15,420 Pcs. SS2FH6HM3/H: 37,443 Pcs. Vishay parts demonstrate significantly higher inventory availability, supporting supply chain continuity for high-volume production requirements.
