SS36L RHG Equivalent & Substitute Parts

Part Overview

The SS36L RHG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 60 V DC reverse voltage and 3 A average rectified current in a surface mount Sub SMA package (DO-219AB). This component is designed for fast recovery applications with switching speeds ≤ 500 ns and operates across a junction temperature range of -55°C to 150°C. The part is ROHS3 compliant and carries unlimited moisture sensitivity classification (MSL 1).

Equivalent and substitute parts are identified based on matching or compatible electrical ratings, package specifications, and thermal operating ranges. Substitutes may vary in current capacity, forward voltage characteristics, or manufacturer origin while maintaining functional compatibility within defined application parameters.

Substitute Part Grouping Explanation

Substitution logic for the SS36L RHG is based on the following criteria:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 60 V reverse voltage rating, 3 A average rectified current, 750 mV forward voltage at 3 A, fast recovery switching speed ≤ 500 ns, and DO-219AB package configuration. These parts differ only in packaging format (tape and reel versus bulk) or manufacturing facility designation.

Similar Substitutes share the same 60 V reverse voltage rating and DO-219AB package but operate at reduced current ratings (1 A or 2 A) or exhibit different forward voltage and leakage characteristics. These parts are suitable for applications where the full 3 A current capacity is not required. Similar substitutes from Vishay General Semiconductor may include automotive-grade qualifications (AEC-Q101) and extended junction temperature ranges (-55°C to 175°C).

All substitute parts maintain Schottky technology, fast recovery switching performance, surface mount configuration, ROHS3 compliance, and unlimited moisture sensitivity classification.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): SS36L RVG is a direct parametric equivalent to SS36L RHG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications, thermal operating range, and package configuration. The primary distinction is packaging format: SS36L RVG is supplied in tape and reel format, while SS36L RHG is supplied in bulk. Selection between these two depends on procurement and assembly requirements rather than functional performance.

Current-Reduced Substitutes (Vishay General Semiconductor): SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are similar substitutes suitable for applications where the full 3 A current capacity of the SS36L RHG is not required. These parts maintain the 60 V reverse voltage rating and DO-219AB package but operate at 1 A or 2 A respectively. The SS1FH6HM3/H and SS2FH6HM3/H variants include automotive-grade qualification (AEC-Q101) and extended junction temperature range (-55°C to 175°C), making them suitable for automotive and high-temperature applications. All Vishay substitutes exhibit lower reverse leakage current (3 µA versus 500 µA) and are ROHS3 compliant.

Compliance and Certification: All listed parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity classification (MSL 1). Automotive-qualified variants (SS1FH6HM3/H and SS2FH6HM3/H) carry AEC-Q101 certification.

Frequently Asked Questions (FAQ)

Q: Can SS36L RVG be used as a direct replacement for SS36L RHG? A: Yes. SS36L RVG is a parametric equivalent with identical electrical specifications, thermal range, and package. The only difference is packaging format (tape and reel versus bulk). Functional performance is equivalent.

Q: What is the primary difference between SS36L RHG and the Vishay substitutes? A: The Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) are rated for lower average rectified currents (1 A or 2 A) compared to the SS36L RHG (3 A). All maintain the same 60 V reverse voltage rating and DO-219AB package. Selection depends on application current requirements.

Q: Can I use SS1FH6-M3/H in place of SS36L RHG in a 3 A application? A: No. SS1FH6-M3/H is rated for maximum 1 A average rectified current. Using it in a 3 A application exceeds its current rating and will result in device failure or degraded performance.

Q: What is the difference between SS1FH6HM3/H and SS1FH6-M3/H? A: Both parts are rated for 1 A at 60 V with identical electrical characteristics. SS1FH6HM3/H includes automotive-grade qualification (AEC-Q101) and extended junction temperature range (-55°C to 175°C), while SS1FH6-M3/H operates to 175°C but lacks automotive certification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts, including SS36L RHG, SS36L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H, are ROHS3 compliant.

Q: What does the packaging format difference (bulk versus tape and reel) mean? A: Bulk packaging (SS36L RHG) is supplied in standard quantities for manual or small-scale assembly. Tape and reel format (SS36L RVG and Vishay parts) is supplied on continuous tape for automated pick-and-place assembly equipment. Electrical performance is identical; selection depends on assembly process requirements.

Q: Can I substitute SS2FH6HM3/H for SS36L RHG in a 2 A application? A: SS2FH6HM3/H is rated for 2 A and maintains the 60 V reverse voltage rating and DO-219AB package. However, forward voltage differs (780 mV @ 2 A versus 750 mV @ 3 A for the SS36L RHG). Substitution is possible if the application tolerates this forward voltage difference and does not require the full 3 A capacity.

Q: What is the significance of reverse leakage current differences? A: SS36L RHG exhibits 500 µA reverse leakage at 60 V, while Vishay substitutes exhibit 3 µA. Lower leakage current reduces power dissipation in reverse bias conditions. Applications sensitive to leakage current performance should account for this difference.

Q: Are automotive-qualified parts (AEC-Q101) required for all applications? A: No. AEC-Q101 qualification is required only for automotive applications. SS1FH6HM3/H and SS2FH6HM3/H include this certification; SS36L RHG, SS36L RVG, and SS1FH6-M3/H do not. Selection depends on application requirements.
