This part is ROHS3 compliant and active. The operating temperature range is -55°C to 150°C, which is narrower at the lower end compared to the S5JC-13 (-65°C to 150°C). This part is suitable for applications where the lower temperature limit of -55°C is acceptable. Inventory availability is 15,400 pcs.

Tertiary Recommendation - Equivalent with Slightly Higher Forward Voltage:

S5JL-TP (Micro Commercial Co) provides 600 V, 5 A rating with forward voltage of 1.2 V at 5 A (compared to 1.15 V for the S5JC-13). This represents a 0.05 V increase in forward voltage drop. The part is ROHS3 compliant and active. Operating temperature range is -55°C to 150°C. This substitution is suitable for applications where the slightly higher forward voltage drop is acceptable. Inventory availability is 2,553 pcs.

Uprated Alternative - Higher Current Capacity:

SMLJ60S6-TP (Micro Commercial Co) provides 600 V, 6 A rating with forward voltage of 1.0 V at 6 A. This part offers enhanced current capacity and lower forward voltage compared to the S5JC-13. The part is ROHS3 compliant and active. Operating temperature range is -55°C to 150°C. This substitution is suitable for applications requiring additional current margin or where lower forward voltage drop is beneficial. Inventory availability is 1,907 pcs.

Lower Current Alternatives - Downrated Substitutes:

MURS360T3G (onsemi), STTH2R06S (STMicroelectronics), STTH3L06S (STMicroelectronics), and STTH3R06S (STMicroelectronics) are lower-rated alternatives with 2 A or 3 A current capacity. These parts are suitable only for applications where circuit current requirements do not exceed their respective ratings. All are ROHS3 compliant and active. These substitutes are not recommended for direct replacement of the 5 A S5JC-13 in circuits designed for 5 A operation.

Compliance Consideration:

The S5JC-13 is RoHS non-compliant. All recommended substitute parts (S5JC-13-F, S5J-E3/57T, S5JL-TP, SMLJ60S6-TP) are ROHS3 compliant, making them suitable for new designs subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can S5JC-13-F be used as a direct replacement for S5JC-13?

A: Yes. The S5JC-13-F is a direct equivalent with identical electrical specifications: 600 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage at 5 A, and standard recovery characteristics. The primary difference is that S5JC-13-F is ROHS3 compliant and currently in active production, whereas the S5JC-13 is discontinued. No circuit modification is required.

Q: What is the difference between standard recovery and fast recovery diodes?

A: Recovery speed refers to the reverse recovery time (trr), which is the time required for a diode to transition from forward conduction to reverse blocking when the applied voltage reverses. Standard recovery diodes have trr >500 ns, while fast recovery diodes have trr ≤500 ns. The S5JC-13 uses standard recovery. Fast recovery diodes (such as STTH series) reduce switching losses in high-frequency applications but may exhibit higher forward voltage. Selection depends on circuit operating frequency and loss requirements.

Q: Can I use SMLJ60S6-TP (6 A) instead of S5JC-13 (5 A)?

A: Yes. The SMLJ60S6-TP is rated for 6 A, which exceeds the 5 A requirement of the S5JC-13. This uprated substitute provides additional current capacity margin. The SMLJ60S6-TP also exhibits lower forward voltage (1.0 V at 6 A versus 1.15 V at 5 A), which reduces power dissipation. This substitution is suitable for applications where additional current headroom is beneficial.

Q: Can I use STTH3R06S (3 A) instead of S5JC-13 (5 A)?

A: No. The STTH3R06S is rated for 3 A average rectified current, which is below the 5 A requirement of the S5JC-13. Using a downrated diode in a circuit designed for 5 A operation will result in excessive current density, leading to thermal stress and potential device failure. Downrated substitutes are suitable only for applications where the actual circuit current requirement does not exceed the substitute part's rating.

Q: What is the significance of the operating temperature range difference between S5JC-13 (-65°C to 150°C) and S5J-E3/57T (-55°C to 150°C)?

A: The S5JC-13 operates at lower junction temperatures down to -65°C, while the S5J-E3/57T minimum is -55°C. If the application requires operation below -55°C, the S5J-E3/57T is not suitable. For applications with minimum operating temperature above -55°C, the S5J-E3/57T is acceptable. The upper temperature limit (150°C) is identical for both parts.

Q: Are all substitute parts available in the same packaging format as S5JC-13?

A: All substitute parts use the DO-214AB SMC surface mount package, which is mechanically and electrically compatible with the S5JC-13. However, packaging formats (Cut Tape, Digi-Reel, Tape & Reel) may differ. S5JC-13-F is available in Cut Tape and Digi-Reel formats. S5J-E3/57T is available in Cut Tape. S5JL-TP and SMLJ60S6-TP are available in Tape & Reel format. Verify packaging format compatibility with your procurement and assembly requirements.

Q: What does RoHS compliance mean for component selection?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of specific hazardous materials in electrical and electronic equipment. The S5JC-13 is RoHS non-compliant, while all recommended substitutes are ROHS3 compliant. For new designs subject to RoHS regulations (particularly in EU markets), ROHS3 compliant parts are required. For legacy designs or applications without RoHS requirements, either compliant or non-compliant parts may be used.

Q: How does forward voltage affect circuit performance?

A: Forward voltage (Vf) is the voltage drop across the diode during forward conduction. Higher forward voltage results in greater power dissipation and heat generation. The S5JC-13 exhibits 1.15 V at 5 A. Substitutes with lower Vf (such as SMLJ60S6-TP at 1.0 V) reduce power loss, while substitutes with higher Vf (such as STTH2R06S at 1.7 V) increase power loss. For high-current or high-frequency applications, forward voltage differences become significant in thermal and efficiency calculations.

Q: What is reverse leakage current and why does it matter?

A: Reverse leakage current (Ir) is the small current that flows through a reverse-biased diode. The S5JC-13 exhibits 10 µA at 600 V. Lower leakage current (such as STTH2R06S at 2 µA) reduces standby power consumption and heat generation. Higher leakage current increases power loss. For most applications, reverse leakage differences are negligible unless the circuit operates in high-temperature environments or requires extremely low standby power consumption.
