Substitute Part Grouping Explanation
Substitute parts for the SS36HM3_A/H are grouped into two categories based on electrical and mechanical compatibility:
Category 1: Vishay Parametric Equivalents (Same Manufacturer) These parts share identical electrical specifications and automotive qualification. Substitution is based on matching:
- Voltage - DC Reverse (Vr) (Max): 60 V
- Current - Average Rectified (Io): 3 A
- Voltage - Forward (Vf) (Max) @ If: 750 mV @ 3 A
- Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
- Current - Reverse Leakage @ Vr: 500 µA @ 60 V
- Package / Case: DO-214AB, SMC
- Operating Temperature - Junction: -55°C to 150°C
- Grade: Automotive
- Qualification: AEC-Q101
- RoHS Status: ROHS3 Compliant
Differences exist only in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and inventory levels.
Category 2: Cross-Manufacturer Parametric Equivalents These parts from Panjit International Inc. and Micro Commercial Co. meet the same electrical ratings and package specifications. Substitution is based on matching:
- Voltage - DC Reverse (Vr) (Max): 60 V
- Current - Average Rectified (Io): 3 A
- Voltage - Forward (Vf) (Max) @ If: 750 mV @ 3 A
- Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
- Package / Case: DO-214AB, SMC
- Operating Temperature - Junction: -55°C to 150°C
- RoHS Status: ROHS3 Compliant
Minor variations in reverse leakage current and capacitance are noted but do not preclude substitution within the same electrical class.
Category 3: Package Variant (SMA) The SS36 from MDD uses a different surface mount package (DO-214AC, SMA) while maintaining identical electrical specifications. This part is suitable for designs that accommodate the SMA package footprint.

Engineering Selection Recommendations
Primary Substitutes (Recommended for Automotive Applications)
SS36HE3_B/H and SS36HE3_B/I are the preferred substitutes for the SS36HM3_A/H. Both parts are manufactured by Vishay, carry AEC-Q101 automotive qualification, maintain Automotive grade designation, and are classified as Active products. These parts provide direct electrical and mechanical compatibility with identical reverse voltage, forward current, and operating temperature specifications.
Secondary Substitutes (Vishay Packaging Variants)
SS36-E3/57T and SS36-E3/9AT are Vishay products with identical electrical specifications and DO-214AB (SMC) package compatibility. These parts differ only in packaging format (Cut Tape & Digi-Reel® and Tape & Reel, respectively) and do not carry explicit automotive grade or AEC-Q101 designation in the provided data. Selection of these parts is appropriate when packaging format requirements align with application needs and automotive qualification is not mandated.
Cross-Manufacturer Substitutes (Active Status)
SK36-AU_R1_000A1 and SK36_R1_00001 from Panjit International Inc. are Active products with AEC-Q101 automotive qualification and identical electrical ratings. These parts feature lower reverse leakage current (100 µA @ 60 V versus 500 µA @ 60 V), which may provide performance benefits in low-leakage applications. Both parts are suitable for automotive designs requiring cross-manufacturer sourcing.
Obsolete Part (Not Recommended)
SK36-TP from Micro Commercial Co. is classified as Obsolete and should not be selected for new designs or long-term production applications.
Package Variant (SMA)
SS36 from MDD provides identical electrical specifications in a DO-214AC (SMA) surface mount package. This part is suitable only for designs with SMA package footprint compatibility and should not be used as a direct replacement for DO-214AB (SMC) packaged designs without PCB layout modification.
Frequently Asked Questions (FAQ)
Q: Can SS36-E3/57T be used as a direct replacement for SS36HM3_A/H?
A: Yes. Both parts share identical electrical specifications: 60 V reverse voltage, 3 A average rectified current, 750 mV forward voltage at 3 A, and DO-214AB (SMC) package. The difference is packaging format: SS36-E3/57T is supplied in Cut Tape & Digi-Reel® format, while SS36HM3_A/H is supplied in Tape & Reel format. Electrical performance and PCB compatibility are equivalent.
Q: What is the difference between SK36-AU_R1_000A1 and SS36HM3_A/H?
A: Both parts meet the same voltage (60 V), current (3 A), and package (DO-214AB, SMC) specifications. The primary difference is reverse leakage current: SK36-AU_R1_000A1 specifies 100 µA @ 60 V, while SS36HM3_A/H specifies 500 µA @ 60 V. SK36-AU_R1_000A1 is manufactured by Panjit International Inc. and carries AEC-Q101 qualification. The lower leakage current may be advantageous in applications sensitive to reverse current.
Q: Is SK36-TP suitable for new designs?
A: No. SK36-TP is classified as Obsolete and should not be selected for new designs or production applications requiring long-term component availability.
Q: Can SS36 (SMA package) replace SS36HM3_A/H (SMC package)?
A: No, not without PCB redesign. SS36 uses a DO-214AC (SMA) package, while SS36HM3_A/H uses a DO-214AB (SMC) package. These packages have different footprints and are not mechanically interchangeable on the same PCB. Electrical specifications are identical, but package compatibility must be verified before substitution.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the compliance profile of SS36HM3_A/H.
Q: Which substitute parts carry AEC-Q101 automotive qualification?
A: SS36HE3_B/H, SS36HE3_B/I, SK36-AU_R1_000A1, and SK36_R1_00001 all carry AEC-Q101 qualification. SS36-E3/57T, SS36-E3/9AT, SK36-TP, and SS36 do not have AEC-Q101 designation in the provided data. For automotive applications requiring AEC-Q101 compliance, select from the qualified parts.
Q: What is the difference between SS36HE3_B/H and SS36HE3_B/I?
A: Both parts are Vishay products with identical electrical specifications, automotive grade designation, and AEC-Q101 qualification. The difference is packaging format: SS36HE3_B/H is supplied in Cut Tape & Digi-Reel® format, while SS36HE3_B/I is supplied in Tape & Reel format. Electrical performance and PCB compatibility are equivalent.
Q: Can I use Panjit SK36 parts in place of Vishay SS36 parts?
A: Yes, provided electrical specifications match. SK36-AU_R1_000A1 and SK36_R1_00001 both meet the 60 V, 3 A, and DO-214AB (SMC) package requirements. Both carry AEC-Q101 qualification. The lower reverse leakage current (100 µA) in Panjit parts may provide performance benefits in specific applications. Verify supplier qualification and quality agreements before cross-manufacturer substitution in production designs.
