Substitute Part Grouping Explanation

Substitution of the SS36-M3/9AT is determined by the following critical parameters: Voltage - DC Reverse (Vr) maximum rating of 60 V, Current - Average Rectified (Io) of 3 A, forward voltage characteristics, fast recovery speed classification, package format DO-214AB (SMC), and surface mount mounting type. Parts are grouped into three categories based on substitution relationship:

Parametric Equivalents (Vishay SS36 Series): Parts SS36-E3/57T, SS36-E3/9AT, SS36HE3_B/H, and SS36HE3_B/I share identical electrical specifications with the main part. Differences exist only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and automotive qualification status. These parts are direct functional replacements.

Parametric Equivalents (Alternative Manufacturers): Parts SK36-TP, SK36-AU_R1_000A1, and SK36_R1_00001 from Micro Commercial Co and Panjit International Inc. meet the same 60 V / 3 A electrical requirements and DO-214AB package specification. Minor variations in reverse leakage current and capacitance are within acceptable tolerance ranges for this device category.

Manufacturer-Recommended Alternatives (STMicroelectronics): Parts STPS3L60S, STPS5L60S, and STPS5L60SY represent higher-current-rated alternatives from STMicroelectronics. STPS3L60S maintains the 3 A rating with improved forward voltage characteristics. STPS5L60S and STPS5L60SY are rated for 5 A operation, providing design margin for applications requiring higher current capacity while maintaining 60 V reverse voltage rating and SMC package compatibility.

Engineering Selection Recommendations

Direct Replacement (Identical Specifications): SS36-E3/57T, SS36-E3/9AT, SS36HE3_B/H, and SS36HE3_B/I are functionally equivalent to SS36-M3/9AT. Selection among these parts depends on packaging format requirements and supply chain availability. SS36HE3_B/H and SS36HE3_B/I carry AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. All Vishay SS36 variants maintain Active product status and RoHS3 compliance.

Alternative Manufacturer Equivalents: SK36-AU_R1_000A1 and SK36_R1_00001 from Panjit International Inc. provide equivalent electrical performance with lower reverse leakage current (100 µA versus 500 µA). SK36-AU_R1_000A1 includes AEC-Q101 automotive qualification. SK36-TP from Micro Commercial Co is electrically equivalent but carries Obsolete product status, limiting suitability for new designs.

Higher Current Capacity Alternatives: STPS5L60S and STPS5L60SY from STMicroelectronics are rated for 5 A operation, providing 67% additional current capacity over the 3 A SS36-M3/9AT rating. These parts maintain 60 V reverse voltage rating and DO-214AB package compatibility. STPS5L60SY includes automotive-grade qualification. Forward voltage is reduced to 520 mV at 5 A, indicating improved thermal performance. These parts are suitable for applications where design margin or future current scaling is required.

Improved Performance Alternative: STPS3L60S from STMicroelectronics maintains the 3 A current rating with improved forward voltage (700 mV versus 750 mV) and significantly reduced reverse leakage current (55 µA versus 500 µA), resulting in lower power dissipation and improved efficiency.

Frequently Asked Questions (FAQ)

Q: Can SS36-E3/57T be used as a direct replacement for SS36-M3/9AT?

A: Yes. SS36-E3/57T is a parametric equivalent with identical electrical specifications (60 V, 3 A, 750 mV forward voltage). The only difference is packaging format: SS36-E3/57T is supplied in Cut Tape & Digi-Reel format while SS36-M3/9AT is Tape & Reel. Both are Active products with RoHS3 compliance. Compatibility depends on assembly equipment capability to handle the respective packaging format.

Q: What is the difference between SS36HE3_B/H and SS36HE3_B/I?

A: Both parts are electrically identical with 60 V / 3 A specifications and AEC-Q101 automotive qualification. SS36HE3_B/H is available in both Cut Tape & Digi-Reel and Tape & Reel formats, while SS36HE3_B/I is Tape & Reel only. Selection depends on packaging format requirements for assembly operations.

Q: Can STPS5L60S replace SS36-M3/9AT in a 3 A application?

A: Yes, with design considerations. STPS5L60S is rated for 5 A operation, providing design margin for the 3 A requirement. The 60 V reverse voltage rating is identical. Forward voltage is 520 mV at 5 A (compared to 750 mV at 3 A for SS36-M3/9AT), indicating lower power dissipation. Reverse leakage is 220 µA at 60 V (compared to 500 µA). The part is electrically compatible and suitable for applications where improved efficiency is beneficial.

Q: Why is SK36-TP listed as Obsolete?

A: SK36-TP from Micro Commercial Co carries Obsolete product status, indicating discontinued manufacturing. While electrically equivalent to SS36-M3/9AT, it is not recommended for new designs. Existing inventory may be available, but long-term supply cannot be assured. Active alternatives such as SS36-E3/9AT or SK36-AU_R1_000A1 are preferred for new applications.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard. Parts carrying this qualification (SS36HE3_B/H, SS36HE3_B/I, SK36-AU_R1_000A1, and STPS5L60SY) have undergone additional testing and validation for automotive applications. These parts are suitable for use in automotive circuits where component reliability and traceability are critical requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference—SS36-M3/9AT and all substitute parts—carry RoHS3 compliance status. All parts are also REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) and Cut Tape & Digi-Reel (CT) are different supply formats for surface mount components. Tape & Reel is a continuous reel suitable for high-speed automated assembly. Cut Tape & Digi-Reel is pre-cut tape on a reel, suitable for lower-volume assembly or manual handling. Both formats contain identical components; selection depends on assembly equipment and production volume requirements.

Q: Can SK36-AU_R1_000A1 be used instead of SS36-M3/9AT?

A: Yes. SK36-AU_R1_000A1 from Panjit International Inc. is a parametric equivalent with identical 60 V / 3 A electrical specifications and DO-214AB package. It includes AEC-Q101 automotive qualification and features lower reverse leakage current (100 µA versus 500 µA), resulting in improved performance. It is supplied in Tape & Reel format and carries Active product status.

Q: What is the operating temperature range for these parts?

A: The SS36-M3/9AT and most substitute parts operate over a junction temperature range of -55°C to 150°C. STPS3L60S and STPS5L60S specify a maximum junction temperature of 150°C without a minimum specification. STPS5L60SY specifies -40°C to 150°C. All parts are suitable for industrial and automotive temperature environments within these ranges.
