Substitute Part Grouping Explanation

Substitute parts for the SS36L RUG are classified into two categories based on electrical parameter compatibility:

Parametric Equivalent: Parts that match all critical electrical specifications including voltage rating, current rating, forward voltage, and reverse leakage characteristics. These parts are direct functional replacements with identical performance parameters.

Similar Parts: Parts that share the same voltage rating (60 V) and package type (DO-219AB) but differ in current rating or other secondary parameters. These parts are suitable for applications where the lower current rating is acceptable or where design margins permit downrating.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 60 V (required match)
Package / Case: DO-219AB or Sub SMA (required match)
Technology: Schottky (required match)

Engineering Selection Recommendations

SS36L RVG (Parametric Equivalent): This part is a direct parametric equivalent to the SS36L RUG, manufactured by Taiwan Semiconductor Corporation. Both parts share identical electrical specifications including 60 V reverse voltage, 3 A average rectified current, 750 mV forward voltage at 3 A, and 500 µA reverse leakage current. Both are ROHS3 compliant with MSL 1 rating and Active product status. The SS36L RVG is suitable for direct substitution in all applications where the SS36L RUG is specified.

SS1FH6-M3/H (Similar Part - Current Downrating): This Vishay part is rated for 1 A average rectified current compared to the 3 A rating of the SS36L RUG. It shares the 60 V reverse voltage rating, DO-219AB package, and fast recovery speed characteristics. The forward voltage is 700 mV at 1 A, and reverse leakage is significantly lower at 3 µA. This part is suitable for applications where the circuit current requirement does not exceed 1 A. The extended operating temperature range (-55°C ~ 175°C) provides additional thermal margin compared to the SS36L RUG.

SS1FH6HM3/H (Similar Part - Automotive Grade, Current Downrating): This Vishay part is rated for 1 A average rectified current and carries automotive grade designation with AEC-Q101 qualification. It is suitable for automotive applications where the circuit current requirement does not exceed 1 A and automotive qualification is required. The extended operating temperature range and lower reverse leakage current provide enhanced reliability for automotive environments.

SS2FH6HM3/H (Similar Part - Automotive Grade, Partial Current Rating): This Vishay part is rated for 2 A average rectified current, providing closer current matching to the SS36L RUG while maintaining automotive grade designation and AEC-Q101 qualification. It is suitable for applications requiring 2 A or less and automotive qualification. The forward voltage is 780 mV at 2 A, and reverse leakage is 3 µA.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status. Selection between similar parts depends on application current requirements and whether automotive qualification is necessary.

Frequently Asked Questions (FAQ)

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

A: Yes. The SS36L RVG is a parametric equivalent with identical electrical specifications. Both parts are manufactured by Taiwan Semiconductor Corporation, rated for 60 V and 3 A, and share the same DO-219AB package and operating temperature range. Direct substitution is supported.

Q: What is the difference between the SS36L RUG and the Vishay SS1FH6-M3/H?

A: The primary difference is the current rating. The SS36L RUG is rated for 3 A average rectified current, while the SS1FH6-M3/H is rated for 1 A. Both share the 60 V reverse voltage rating and DO-219AB package. The SS1FH6-M3/H has lower reverse leakage current (3 µA versus 500 µA) and an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C). The SS1FH6-M3/H is suitable only for applications where the circuit current does not exceed 1 A.

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

A: Yes. Automotive-grade parts with AEC-Q101 qualification meet or exceed the requirements for standard industrial applications. These parts can be used in non-automotive circuits. The automotive qualification indicates enhanced reliability and stricter manufacturing controls.

Q: What does the DO-219AB package designation mean?

A: DO-219AB is the standardized package designation for surface mount Schottky diodes in the Sub SMA form factor. All listed parts use this package, ensuring mechanical and electrical compatibility in PCB layouts designed for this package type.

Q: Why does the SS36L RUG have higher reverse leakage current (500 µA) compared to the Vishay parts (3 µA)?

A: Reverse leakage current is a characteristic of the specific diode design and manufacturing process. The Taiwan Semiconductor Corporation SS36L RUG and SS36L RVG are specified with 500 µA reverse leakage at 60 V, while the Vishay parts are specified with 3 µA. Both values are within acceptable ranges for Schottky diode applications. Selection should be based on application requirements for leakage current performance.

Q: Can I use the SS2FH6HM3/H (2 A rated) in place of the SS36L RUG (3 A rated)?

A: The SS2FH6HM3/H can be used if the application circuit current does not exceed 2 A. If the circuit requires the full 3 A capability of the SS36L RUG, the SS2FH6HM3/H is not suitable. For applications requiring 3 A operation, use the SS36L RVG parametric equivalent or the original SS36L RUG.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All parts listed—SS36L RUG, SS36L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the significance of the AEC-Q101 qualification on the Vishay automotive parts?

A: AEC-Q101 is the automotive electronics council qualification standard for discrete semiconductors. Parts carrying this qualification have undergone rigorous testing for reliability, temperature cycling, and performance stability under automotive operating conditions. This qualification is required for automotive applications but is not necessary for standard industrial use.
