Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SS26LHRTG is determined by the following critical parameters: voltage rating (60 V DC reverse), current rating (2 A average rectified), package type (DO-219AB / Sub SMA), technology (Schottky), and mounting configuration (surface mount). Parts are grouped into two categories based on parametric equivalence:

Parametric Equivalent (Full Substitution): Parts that match all critical electrical parameters (60 V, 2 A) and package specifications. The SS26L RVG from Taiwan Semiconductor Corporation qualifies as a parametric equivalent with identical voltage, current, forward voltage, and package characteristics.

Similar Parts (Partial Substitution with Current Derating): Parts that match voltage rating (60 V), package type (DO-219AB), and technology (Schottky) but have reduced current ratings (1 A). The SS1FH6-M3/H and SS1FH6HM3/H from Vishay General Semiconductor are classified as similar parts. These require current derating consideration in circuit design. The SS2FH6HM3/H from Vishay General Semiconductor matches the 2 A current rating and 60 V voltage rating but exhibits a higher forward voltage specification (780 mV @ 2 A versus 700 mV @ 2 A).

Parameter Comparison

Engineering Selection Recommendations

SS26L RVG (Parametric Equivalent): This part is the direct parametric equivalent to SS26LHRTG. Both components share identical electrical specifications (60 V, 2 A, 700 mV forward voltage) and package configuration. SS26L RVG is suitable for direct substitution in applications where the original part is unavailable. Note that SS26L RVG does not carry specified automotive grade or AEC-Q101 qualification in the provided data; verification of compliance requirements for specific applications is necessary based on end-use specifications.

SS1FH6HM3/H (Similar Part with Automotive Qualification): This Vishay part carries AEC-Q101 automotive qualification and operates across an extended temperature range (-55°C ~ 175°C). However, the current rating is reduced to 1 A, requiring circuit design adjustment for applications originally specified at 2 A. The reverse leakage current is significantly lower (3 µA versus 400 µA), which may provide performance benefits in low-leakage applications. This part is suitable for automotive applications where current requirements do not exceed 1 A.

SS2FH6HM3/H (Similar Part with 2 A Rating): This Vishay part maintains the 2 A current rating and carries AEC-Q101 automotive qualification. The forward voltage specification is 780 mV @ 2 A, representing an 80 mV increase compared to the SS26LHRTG specification. This higher forward voltage results in increased power dissipation and must be evaluated against thermal design constraints. The extended operating temperature range (-55°C ~ 175°C) and lower reverse leakage current (3 µA) are additional characteristics. This part is suitable for 2 A applications where the higher forward voltage is acceptable.

SS1FH6-M3/H (Similar Part without Automotive Qualification): This Vishay part is rated for 1 A and does not carry specified automotive grade or AEC-Q101 qualification. It is suitable for non-automotive applications requiring 60 V / 1 A Schottky diode functionality. The extended temperature range (-55°C ~ 175°C) and lower reverse leakage current (3 µA) are available characteristics.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26LHRTG?

A: Yes. SS26L RVG is a parametric equivalent with matching voltage (60 V), current (2 A), forward voltage (700 mV @ 2 A), and package specifications (DO-219AB). Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3. Packaging format differs (SS26L RVG is supplied in Cut Tape versus SS26LHRTG in standard packaging), which may affect procurement and assembly processes.

Q: Can 1 A rated parts (SS1FH6-M3/H or SS1FH6HM3/H) replace the 2 A SS26LHRTG?

A: Substitution of 1 A parts for a 2 A application requires circuit design modification. If the application operates at or near 2 A, the 1 A parts will operate outside their rated current specification. If the actual circuit current is ≤ 1 A, these parts are suitable substitutes. SS1FH6HM3/H carries AEC-Q101 automotive qualification, making it appropriate for automotive applications operating at ≤ 1 A.

Q: What is the impact of the higher forward voltage in SS2FH6HM3/H (780 mV @ 2 A)?

A: The 80 mV increase in forward voltage (from 700 mV to 780 mV at 2 A) results in proportionally higher power dissipation in the diode. For a 2 A circuit, this represents an additional 160 mW of dissipation. Thermal design must accommodate this increased power. Applications with tight thermal budgets or high-frequency switching may require thermal analysis before substitution.

Q: Are all substitute parts automotive qualified?

A: No. SS26L RVG and SS1FH6-M3/H do not carry specified AEC-Q101 qualification in the provided data. SS1FH6HM3/H and SS2FH6HM3/H both carry AEC-Q101 automotive qualification. For automotive applications, use only AEC-Q101 qualified parts.

Q: What is the difference in reverse leakage current between the main part and substitutes?

A: SS26LHRTG specifies 400 µA @ 60 V reverse leakage. All Vishay substitute parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA @ 60 V, representing a 133-fold reduction. Applications sensitive to reverse leakage current benefit from Vishay parts. Applications where reverse leakage is not a constraint are unaffected by this difference.

Q: Can packaging format differences affect substitution?

A: Yes. SS26LHRTG is supplied in standard packaging, while SS26L RVG is supplied in Cut Tape (CT) format. Tape & Reel (TR) packaging is used for SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H. Packaging format affects procurement, storage, and assembly line compatibility. Verify that assembly equipment and processes support the substitute part packaging format before implementation.

Q: What is the operating temperature range difference?

A: SS26LHRTG operates from -55°C to 150°C. All Vishay substitute parts operate from -55°C to 175°C, providing a 25°C extended upper temperature range. Applications operating near the upper temperature limit of SS26LHRTG benefit from the extended range of Vishay parts.
