Substitute Part Grouping Explanation

Substitution of the SS36L RFG is determined by the following critical parameters:

Parametric Equivalents share identical electrical specifications: 60 V reverse voltage rating, 3 A average rectified current, 750 mV forward voltage drop at 3 A, fast recovery characteristics, and DO-219AB package format. These parts are functionally interchangeable with no derating required.

Similar Substitutes maintain the same 60 V reverse voltage rating and DO-219AB package but differ in current rating (1 A or 2 A) and forward voltage characteristics. These parts are suitable only for applications where the lower current rating meets circuit requirements. Current rating is the primary limiting factor for substitution.

The following parameters establish substitution boundaries:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60 V
Package / Case: Must be DO-219AB or Sub SMA equivalent
Mounting Type: Must be Surface Mount
Technology: Must be Schottky
Operating Temperature Range: Must support -55°C to 150°C minimum

Engineering Selection Recommendations

SS36L RVG is a direct parametric equivalent manufactured by Taiwan Semiconductor Corporation. This part maintains identical electrical specifications and package format. The primary distinction is packaging format: SS36L RVG is supplied in Tape & Reel format with significantly higher inventory availability (13,603 pcs) compared to SS36L RFG. Selection of SS36L RVG is appropriate when Tape & Reel packaging accommodates assembly processes and inventory requirements.

SS1FH6-M3/H and SS1FH6HM3/H are 1 A rated Schottky diodes from Vishay General Semiconductor - Diodes Division. These parts are suitable substitutes only for applications where circuit current requirements do not exceed 1 A. Both maintain 60 V reverse voltage rating and DO-219AB package compatibility. SS1FH6HM3/H includes AEC-Q101 automotive qualification, making it appropriate for automotive applications requiring this certification.

SS2FH6HM3/H is a 2 A rated Schottky diode from Vishay General Semiconductor - Diodes Division. This part is suitable for applications requiring current ratings between 1 A and 3 A, provided circuit design accommodates the 780 mV forward voltage drop at 2 A. This part includes AEC-Q101 automotive qualification and extended operating temperature range to 175°C.

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and fast recovery characteristics. Selection among similar substitutes depends on application current requirements and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can SS36L RVG directly replace SS36L RFG?

A: Yes. SS36L RVG is a parametric equivalent with identical electrical specifications (60 V, 3 A, 750 mV forward voltage) and package format (DO-219AB). The difference is packaging format: SS36L RVG is supplied in Tape & Reel format.

Q: What is the primary limitation when substituting with SS1FH6-M3/H or SS1FH6HM3/H?

A: Current rating is the limiting factor. These parts are rated for 1 A average rectified current, compared to 3 A for the SS36L RFG. Substitution is valid only when circuit current requirements do not exceed 1 A.

Q: Can SS2FH6HM3/H replace SS36L RFG in all applications?

A: SS2FH6HM3/H is rated for 2 A, which is below the 3 A rating of SS36L RFG. This part is suitable only for applications where maximum circuit current does not exceed 2 A. Forward voltage drop is 780 mV at 2 A, compared to 750 mV at 3 A for the original part.

Q: Are all substitute parts compatible with the DO-219AB package footprint?

A: Yes. All listed substitute parts use DO-219AB package format, ensuring mechanical and electrical compatibility with existing PCB layouts designed for SS36L RFG.

Q: What is the difference between SS1FH6HM3/H and SS1FH6-M3/H?

A: Both parts are 1 A rated Schottky diodes with identical electrical specifications. SS1FH6HM3/H includes AEC-Q101 automotive qualification and is designated for automotive applications. SS1FH6-M3/H is the standard industrial version without automotive qualification.

Q: Do substitute parts support the same operating temperature range?

A: SS36L RVG supports -55°C to 150°C, matching the original part. Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) support extended range of -55°C to 175°C, providing additional thermal margin.

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

A: SS36L RFG and SS36L RVG specify 500 µA reverse leakage at 60 V. Vishay substitutes specify 3 µA at 60 V, representing significantly lower leakage. Lower leakage current reduces power dissipation in reverse bias conditions and may improve circuit efficiency.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts maintain RoHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements.
