Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S5KL-TP are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 800 V
• Current - Average Rectified (Io): Equal to or greater than 5 A
• Package / Case: DO-214AB, SMC (mechanical compatibility)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Current - Reverse Leakage @ Vr: Consistent with standard rectifier specifications
• Operating Temperature - Junction: Suitable for intended application environment
• Product Status: Active

Substitute parts are grouped into two categories based on voltage rating alignment:

Category 1 - Direct Voltage Match (800 V): Parts with 800 V DC reverse voltage rating provide direct electrical equivalence to the S5KL-TP.

Category 2 - Higher Voltage Rating (1000 V): Parts with 1000 V DC reverse voltage rating exceed the minimum requirement and are suitable for applications where the S5KL-TP is specified, provided circuit design accommodates the higher voltage capability.

Parameter Comparison

Engineering Selection Recommendations

S5KC-13-F (Diodes Incorporated)

The S5KC-13-F is a direct electrical equivalent to the S5KL-TP, matching the 800 V DC reverse voltage and 5 A current rating. Both components share identical package specifications (DO-214AB, SMC), mounting type (Surface Mount), and compliance certifications (ROHS3, MSL 1). The S5KC-13-F exhibits a lower forward voltage drop (1.15 V versus 1.2 V at 5 A), which may provide marginal efficiency benefits in power conversion applications. Operating temperature range extends to -65°C, providing enhanced low-temperature performance compared to the S5KL-TP. This part is suitable for direct substitution in applications where the S5KL-TP is specified.

S5M_R1_00001 (Panjit International Inc.)

The S5M_R1_00001 is rated for 1000 V DC reverse voltage with 5 A average rectified current, exceeding the S5KL-TP voltage specification by 200 V. This higher voltage rating accommodates applications requiring additional voltage margin or where circuit design incorporates higher transient voltages. The forward voltage drop is lower (1.1 V at 5 A), and the package remains compatible (DO-214AB, SMC). All compliance certifications align with the S5KL-TP. This part is suitable for substitution in applications where the higher voltage rating does not create design constraints.

STTH310S (STMicroelectronics)

The STTH310S is rated for 1000 V DC reverse voltage but with a reduced current rating of 3 A, which is below the S5KL-TP specification of 5 A. This part exhibits fast recovery characteristics (≤500 ns) compared to the standard recovery speed of the S5KL-TP (>500 ns). The forward voltage drop is significantly higher (1.7 V at 3 A). The STTH310S is not suitable for direct substitution in applications requiring 5 A continuous current. This part is applicable only in circuits where the maximum current requirement does not exceed 3 A and where fast recovery characteristics provide circuit performance benefits.

Frequently Asked Questions (FAQ)

Q: Can the S5KC-13-F replace the S5KL-TP in all applications?

A: Yes. The S5KC-13-F meets or exceeds all critical electrical parameters of the S5KL-TP: 800 V reverse voltage rating, 5 A current rating, identical package (DO-214AB, SMC), and equivalent compliance certifications. The lower forward voltage drop (1.15 V versus 1.2 V) and extended low-temperature operating range (-65°C versus -55°C) represent performance improvements.

Q: Is the S5M_R1_00001 suitable for the S5KL-TP application?

A: The S5M_R1_00001 is suitable for substitution provided the circuit design accommodates the higher 1000 V voltage rating. The part meets the 5 A current requirement and maintains package compatibility. The lower forward voltage drop (1.1 V) may improve efficiency. Verify that the higher voltage rating does not create design conflicts or introduce unintended circuit behavior.

Q: Why is the STTH310S listed as a substitute if it has lower current rating?

A: The STTH310S is listed as a substitute part but is not recommended for direct replacement in applications requiring 5 A continuous current. This part is applicable only in circuits where maximum current does not exceed 3 A. The fast recovery characteristic (≤500 ns) may provide benefits in specific switching applications where recovery speed is critical.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in DO-214AB, SMC package format with Surface Mount mounting type. All parts are available in Tape & Reel (TR) or Cut Tape (CT) packaging options suitable for automated assembly processes.

Q: What compliance certifications apply to all parts in this comparison?

A: All parts listed (S5KL-TP, S5KC-13-F, S5M_R1_00001, and STTH310S) are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All parts are classified as Active product status.

Q: How do forward voltage drops affect circuit performance?

A: Forward voltage drop (Vf) directly impacts power dissipation and efficiency in rectifier circuits. The S5KL-TP specifies 1.2 V at 5 A, while the S5KC-13-F and S5M_R1_00001 specify lower values (1.15 V and 1.1 V respectively). Lower forward voltage reduces heat generation and improves overall power conversion efficiency. The STTH310S specifies 1.7 V at 3 A, which is higher and results in greater power dissipation.

Q: What is the significance of recovery speed classification?

A: Recovery speed indicates the time required for the diode to transition from forward conduction to reverse blocking state. Standard recovery (>500 ns) is suitable for general-purpose rectification and power supply applications. Fast recovery (≤500 ns) is beneficial in high-frequency switching circuits where reduced recovery time minimizes switching losses and improves efficiency. The S5KL-TP, S5KC-13-F, and S5M_R1_00001 are standard recovery devices, while the STTH310S is fast recovery.
