Substitute Part Grouping Explanation

Substitution of the SK36-7-F is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V (exact match required)
Current - Average Rectified (Io): 3 A (exact match required)
Technology: Schottky (exact match required)
Mounting Type: Surface Mount (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (exact match required)

Secondary Compatibility Parameters:

Voltage - Forward (Vf) (Max) @ If: 750 mV @ 3 A or lower (lower values indicate improved performance)
Current - Reverse Leakage @ Vr: 500 µA @ 60 V or lower (lower values indicate improved performance)
Operating Temperature - Junction: Must support application requirements
RoHS Status: ROHS3 Compliant preferred for regulatory alignment

Substitute parts meeting all primary criteria are considered direct functional equivalents. Parts with improved secondary parameters (lower forward voltage, lower reverse leakage) provide enhanced performance characteristics while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

Primary Recommendation: B360-13-F (Diodes Incorporated)

The B360-13-F is the manufacturer-recommended direct substitute for the SK36-7-F. Both components are manufactured by Diodes Incorporated, ensuring design continuity and supply chain consistency. The B360-13-F is classified as Active, providing reliable long-term availability. It meets all primary substitution criteria with identical voltage and current ratings, maintains the same SMC package configuration, and is ROHS3 Compliant. The forward voltage is improved at 700 mV versus 750 mV, providing enhanced efficiency. Inventory availability is substantial at 50,200 pieces.

Secondary Recommendation: STPS3L60S (STMicroelectronics)

The STPS3L60S meets all primary substitution criteria and offers superior performance characteristics. Forward voltage is reduced to 700 mV, and reverse leakage current is significantly lower at 55 µA compared to 500 µA. The component is Active with strong inventory availability (25,050 pieces) and is ROHS3 Compliant. Operating temperature range is -55°C to 150°C, suitable for most applications.

Alternative Recommendation: HSM360JE3/TR13 (Microchip Technology)

The HSM360JE3/TR13 provides the most enhanced performance profile among available substitutes. Forward voltage is reduced to 620 mV, and reverse leakage current is minimized at 100 µA. Operating temperature range extends to 175°C maximum, supporting high-temperature applications. The component is Active and ROHS3 Compliant. Inventory is limited at 850 pieces, requiring lead time consideration.

Obsolete Alternative: SK36-TP (Micro Commercial Co)

The SK36-TP is functionally equivalent to the SK36-7-F with identical electrical specifications. However, it is classified as Obsolete, limiting its suitability for new designs or long-term supply assurance. This part is listed only for reference in legacy system maintenance scenarios where existing inventory exists.

Non-Recommended: STPS2L60, HSM560JE3/TR13, SS36

The STPS2L60 is rated for 2 A current, below the 3 A requirement. The HSM560JE3/TR13 is rated for 5 A current, exceeding the 3 A specification. The SS36 uses a different package (DO-214AC, SMA) incompatible with SMC footprints. These parts do not meet primary substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can the B360-13-F be used as a direct replacement for SK36-7-F in existing designs?

A: Yes. The B360-13-F meets all primary substitution criteria: 60 V reverse voltage, 3 A current rating, Schottky technology, surface mount configuration, and DO-214AB SMC package. Both components are manufactured by Diodes Incorporated. The B360-13-F is the manufacturer-recommended substitute and is classified as Active, ensuring supply continuity.

Q: What is the difference between STPS3L60S and STPS3L60SY?

A: Both parts are manufactured by STMicroelectronics and meet all primary substitution criteria with identical electrical specifications. The STPS3L60SY includes automotive-grade qualification (Grade: Automotive) and operates across a wider temperature range (-40°C to 150°C) compared to the STPS3L60S (-55°C to 150°C). Selection depends on application requirements and automotive compliance needs.

Q: Why is HSM360JE3/TR13 recommended despite lower inventory availability?

A: The HSM360JE3/TR13 offers superior electrical performance with forward voltage reduced to 620 mV (versus 750 mV) and reverse leakage current minimized to 100 µA (versus 500 µA). These improvements reduce power dissipation and enhance circuit efficiency. The extended operating temperature range to 175°C supports high-temperature applications. Limited inventory (850 pieces) requires advance procurement planning but does not preclude its use in applications where performance optimization is prioritized.

Q: Can STPS2L60 be used if the application requires only 2 A current?

A: No. The STPS2L60 is a through-hole component (DO-204AL, DO-41 package) incompatible with surface mount SMC footprints. Additionally, it uses a different package type, requiring PCB redesign. If the application truly requires only 2 A, the STPS2L60 would necessitate complete circuit board modification and is not a direct substitute.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode's reverse recovery time is less than or equal to 500 nanoseconds when switching from forward conduction to reverse blocking at currents exceeding 200 mA. This fast recovery characteristic is essential for high-frequency switching applications and reduces switching losses. All recommended substitutes meet this specification.

Q: Is RoHS3 compliance important for part selection?

A: RoHS3 compliance is mandatory for products sold into European markets and increasingly required by global OEMs. All recommended active substitutes (B360-13-F, STPS3L60S, STPS3L60SY, HSM360JE3/TR13) are ROHS3 Compliant. The SK36/TR13 is RoHS non-compliant and should be avoided for new designs unless legacy system maintenance is the sole requirement.

Q: What is the significance of the operating temperature range difference between SK36-7-F (-65°C to 150°C) and B360-13-F (-55°C to 150°C)?

A: The SK36-7-F supports operation down to -65°C, while the B360-13-F minimum is -55°C. For applications operating below -55°C, the B360-13-F is not suitable. However, most commercial and industrial applications operate within the -55°C to 150°C range. If the application requires -65°C operation, alternative substitutes must be evaluated or the original SK36-7-F must be sourced from remaining inventory.

Q: Can multiple substitute parts be used interchangeably on the same PCB?

A: Yes, provided all parts meet the primary substitution criteria and the PCB footprint accommodates the DO-214AB SMC package. All recommended substitutes use identical package geometry. However, mixed part numbers on a single PCB may complicate inventory management and traceability. Standardizing on a single substitute part number is recommended for production consistency.
