Substitute Part Grouping Explanation

Substitution of the SS36L R3G is determined by the following critical parameters: voltage rating (60 V DC reverse), current rating (3 A average rectified), forward voltage characteristics, package type (DO-219AB / Sub SMA), mounting method (surface mount), and operating temperature range. Parts are grouped into two categories:

Parametric Equivalent: Parts with identical electrical specifications and packaging, differing only in supplier packaging format (Tape & Reel versus individual packaging).

Similar Parts with Reduced Current Rating: Parts with matching voltage ratings and package types but lower current ratings (1 A or 2 A). These parts operate within the same voltage envelope and package footprint but are suitable only for applications requiring lower current capacity.

Engineering Selection Recommendations

SS36L RVG (Parametric Equivalent): This part is a direct parametric equivalent to the SS36L R3G, manufactured by the same supplier with identical electrical specifications and operating temperature range. The only difference is the packaging format (Tape & Reel versus individual packaging). Selection of SS36L RVG is appropriate when bulk procurement or automated assembly processes require tape and reel packaging. Both parts maintain Active product status and ROHS3 compliance.

SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H (Similar Parts with Reduced Current Rating): These Vishay parts share the same 60 V voltage rating and DO-219AB package footprint but are rated for lower average rectified currents (1 A or 2 A). These parts are suitable only for circuit designs where the maximum current requirement does not exceed their respective ratings. The SS1FH6HM3/H and SS2FH6HM3/H carry automotive-grade qualification (AEC-Q101) and extended operating temperature range (-55°C ~ 175°C), providing additional thermal margin compared to the SS36L R3G. All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can SS36L RVG be used as a direct replacement for SS36L R3G?

A: Yes. SS36L RVG is a parametric equivalent with identical electrical specifications, voltage rating (60 V), current rating (3 A), forward voltage characteristics, and operating temperature range (-55°C ~ 150°C). The difference is packaging format: SS36L RVG is supplied in Tape & Reel format while SS36L R3G is supplied individually. Both are manufactured by Taiwan Semiconductor Corporation and are ROHS3 compliant.

Q: Can the Vishay SS1FH6-M3/H or SS1FH6HM3/H be used in place of SS36L R3G?

A: These parts are suitable only if the circuit design requires a maximum current of 1 A or less. Both parts share the 60 V voltage rating and DO-219AB package, but their 1 A current rating is lower than the SS36L R3G's 3 A rating. Using these parts in a circuit designed for 3 A operation will result in component overstress and failure.

Q: Can the Vishay SS2FH6HM3/H be used in place of SS36L R3G?

A: This part is suitable only if the circuit design requires a maximum current of 2 A or less. The SS2FH6HM3/H shares the 60 V voltage rating and DO-219AB package but is rated for 2 A average rectified current, which is lower than the SS36L R3G's 3 A rating. Using this part in a circuit designed for 3 A operation will result in component overstress and failure.

Q: What is the difference between the SS36L R3G and the Vishay alternatives in terms of reverse leakage current?

A: The SS36L R3G has a reverse leakage current of 500 µA @ 60 V, while the Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) have a reverse leakage current of 3 µA @ 60 V. The Vishay parts exhibit significantly lower leakage, which may be beneficial in low-power or high-impedance circuit applications.

Q: Are all substitute parts available in the same package footprint?

A: Yes. All listed substitute parts use the DO-219AB package, which is the same physical footprint as the Sub SMA package of the SS36L R3G. This ensures mechanical compatibility on printed circuit boards without layout modifications.

Q: Do the Vishay automotive-grade parts (SS1FH6HM3/H and SS2FH6HM3/H) offer any advantages over the standard parts?

A: The Vishay automotive-grade parts carry AEC-Q101 qualification and support an extended operating temperature range of -55°C ~ 175°C compared to the SS36L R3G's -55°C ~ 150°C range. These parts are suitable for applications requiring automotive-grade reliability or operation at elevated junction temperatures. However, their lower current ratings (1 A and 2 A respectively) limit their use to circuits designed for those current levels.

Q: What is the significance of the "Fast Recovery ≤ 500ns, > 200mA (Io)" specification?

A: This specification indicates that all listed parts have fast recovery time characteristics, with recovery time not exceeding 500 nanoseconds for reverse recovery currents greater than 200 mA. This fast recovery behavior is essential for high-frequency switching applications and reduces switching losses in power conversion circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including SS36L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H, are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component procurement.
