Substitute Part Grouping Explanation

Substitution logic for the SS36LHM2G is based on the following critical parameters: voltage rating (60 V DC reverse), current rating (3 A average rectified), forward voltage characteristics, fast recovery speed, Schottky technology, DO-219AB package, surface mount configuration, and automotive-grade qualification with AEC-Q101 certification.

Substitute parts are grouped into two categories:

Parametric Equivalent: Parts that match all critical electrical parameters and maintain identical current and voltage ratings.

Similar Parts: Parts that share the same voltage rating (60 V) and package (DO-219AB) but differ in current rating (1 A or 2 A) or other secondary parameters. These parts are suitable for applications with lower current requirements or where design flexibility permits current derating.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 3 A (parametric equivalent) or lower (similar)
Package / Case: DO-219AB
Technology: Schottky
Mounting Type: Surface Mount
Operating Temperature Range compatibility

Engineering Selection Recommendations

SS36L RVG (Parametric Equivalent): This part is a direct parametric equivalent to the SS36LHM2G, manufactured by Taiwan Semiconductor Corporation. Both parts share identical electrical specifications: 60 V reverse voltage, 3 A average rectified current, 750 mV forward voltage at 3 A, and fast recovery speed. Both are ROHS3 compliant. The primary difference is packaging format: SS36L RVG is supplied in Tape & Reel (TR) configuration, while SS36LHM2G packaging is not specified. Selection of SS36L RVG is appropriate for applications requiring the same electrical performance with alternative packaging logistics. Note that SS36L RVG does not list automotive grade or AEC-Q101 qualification in the provided data.

SS1FH6HM3/H (Similar Part - Automotive Qualified): This Vishay part maintains 60 V reverse voltage and DO-219AB package compatibility but is rated for 1 A average rectified current. It carries automotive grade designation and AEC-Q101 qualification, matching the compliance profile of the SS36LHM2G. Operating temperature range extends to 175°C. Selection is appropriate for applications with current requirements of 1 A or lower, or where design permits current derating. Reverse leakage is significantly lower (3 µA vs. 500 µA).

SS2FH6HM3/H (Similar Part - Automotive Qualified): This Vishay part maintains 60 V reverse voltage and DO-219AB package compatibility with 2 A average rectified current rating. It carries automotive grade designation and AEC-Q101 qualification. Operating temperature range extends to 175°C. Selection is appropriate for applications with current requirements between 1 A and 2 A, or where design permits current derating from the 3 A specification. Reverse leakage is significantly lower (3 µA vs. 500 µA).

SS1FH6-M3/H (Similar Part - Non-Automotive): This Vishay part maintains 60 V reverse voltage and DO-219AB package compatibility with 1 A average rectified current rating. It does not carry automotive grade or AEC-Q101 qualification. Operating temperature range extends to 175°C. Selection is appropriate only for non-automotive applications with 1 A or lower current requirements.

Frequently Asked Questions (FAQ)

Q: Can SS36L RVG be used as a direct replacement for SS36LHM2G?

A: SS36L RVG is a parametric equivalent with identical electrical specifications (60 V, 3 A, 750 mV forward voltage, fast recovery). Both use DO-219AB package and are ROHS3 compliant. The primary difference is packaging format (Tape & Reel vs. unspecified). Direct substitution is supported from an electrical standpoint. However, SS36L RVG does not list automotive grade or AEC-Q101 qualification in the provided data, which may be a consideration for automotive applications.

Q: Can I use SS1FH6HM3/H or SS2FH6HM3/H instead of SS36LHM2G?

A: These Vishay parts share the same 60 V voltage rating and DO-219AB package. However, they have lower current ratings (1 A and 2 A respectively, compared to 3 A). Substitution is possible only if your application current requirement is within the lower rating. Both parts carry automotive grade and AEC-Q101 qualification, matching the compliance profile of the SS36LHM2G. Operating temperature range extends to 175°C, providing additional thermal margin.

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

A: Taiwan Semiconductor Corporation manufactures the SS36LHM2G and SS36L RVG. Vishay General Semiconductor - Diodes Division manufactures the SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H series. All parts use Schottky technology and DO-219AB package. Vishay parts feature lower reverse leakage current (3 µA vs. 500 µA) and extended operating temperature range to 175°C. Vishay automotive-qualified variants (SS1FH6HM3/H and SS2FH6HM3/H) carry AEC-Q101 certification.

Q: Are all these parts in the same package?

A: Yes, all listed parts use the DO-219AB package (Sub SMA / SMF form factor) for surface mount applications. Packaging format differs: SS36LHM2G packaging is unspecified, SS36L RVG is supplied in Tape & Reel (TR), and Vishay parts are supplied in Tape & Reel (TR). The physical component package is identical; only the supply format differs.

Q: Which part should I select for an automotive application?

A: For automotive applications requiring 3 A at 60 V, SS36LHM2G is the primary selection with automotive grade and AEC-Q101 qualification. SS36L RVG is a parametric equivalent but does not list automotive qualification in the provided data. For applications with lower current requirements (1 A or 2 A), SS1FH6HM3/H and SS2FH6HM3/H are automotive-qualified alternatives with AEC-Q101 certification.

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

A: SS36LHM2G and SS36L RVG specify 500 µA reverse leakage at 60 V, while Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA. Lower reverse leakage reduces standby power dissipation and improves circuit efficiency. Selection depends on application requirements for leakage current performance.

Q: Can I use SS1FH6-M3/H in an automotive application?

A: SS1FH6-M3/H does not carry automotive grade or AEC-Q101 qualification. It is suitable only for non-automotive applications. For automotive use, select SS1FH6HM3/H or SS2FH6HM3/H, which carry AEC-Q101 qualification, or use SS36LHM2G as the primary specification.

Q: What is the operating temperature range difference?

A: SS36LHM2G and SS36L RVG specify -55°C to 150°C junction temperature range. Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify -55°C to 175°C, providing 25°C additional thermal margin. Selection depends on application thermal requirements.
