S15JC Equivalent & Substitute Parts Reference

Part Overview

The S15JC is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 15 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when design requirements permit operation at different current ratings, alternative manufacturing sources, or enhanced qualification levels while maintaining core electrical and mechanical compatibility within the DO-214AB package family.

Substitute Part Grouping Explanation

Substitute parts for the S15JC are classified based on the following substitution criteria:

Parametric Equivalent Classification: Parts that maintain identical electrical specifications across voltage rating, current rating, forward voltage, recovery speed, and reverse leakage characteristics, with identical package and temperature range. These parts are direct functional replacements.

Similar Classification: Parts that share the same voltage rating and package but differ in one or more of the following parameters: average rectified current, forward voltage characteristics, recovery speed, reverse leakage current, or operating temperature range. Similar parts require design verification to confirm suitability for the intended application.

The key parameters determining substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): 600 V (required match)
• Package / Case: DO-214AB, SMC (required match)
• Current - Average Rectified (Io): application-dependent tolerance
• Voltage - Forward (Vf) (Max) @ If: thermal and efficiency considerations
• Speed characteristics: circuit timing and EMI performance
• Operating Temperature - Junction: thermal environment compatibility

Parameter Comparison

Engineering Selection Recommendations

S15JCH (Parametric Equivalent): The S15JCH is a direct parametric equivalent to the S15JC with identical electrical specifications and operating temperature range. The S15JCH carries AEC-Q101 automotive qualification, making it suitable for applications requiring automotive-grade component certification. Both parts are manufactured by Taiwan Semiconductor Corporation and are RoHS3 compliant. Selection between S15JC and S15JCH depends on qualification requirements; S15JCH is specified when automotive-grade reliability is mandated.

S8CJ-M3/I (Similar - Reduced Current Rating): The S8CJ-M3/I is a 8 A rated diode from Vishay General Semiconductor - Diodes Division, sharing the 600 V voltage rating and DO-214AB package. This part is suitable only for applications where the maximum average rectified current requirement does not exceed 8 A. The forward voltage at rated current is lower (985 mV @ 8 A versus 1.1 V @ 15 A), resulting in reduced power dissipation in current-limited applications. Operating temperature range and recovery speed characteristics are identical to the S15JC. Selection of S8CJ-M3/I requires confirmation that circuit current demands remain within the 8 A maximum rating.

MURS360T3G (Similar - Reduced Current Rating, Fast Recovery): The MURS360T3G is a 3 A rated diode from onsemi with 600 V voltage rating and DO-214AB package. This part features fast recovery characteristics (≤500 ns) compared to the standard recovery (>500 ns) of the S15JC, and operates across an extended temperature range (-65 to 175 °C). The MURS360T3G is applicable only to designs where average rectified current does not exceed 3 A. The fast recovery characteristic and extended temperature range may provide advantages in high-frequency switching or extreme thermal environments, provided current requirements are satisfied. Selection requires verification that circuit current demands remain within the 3 A maximum rating.

Frequently Asked Questions (FAQ)

Q: Can the S15JCH be used as a direct replacement for the S15JC?

A: Yes. The S15JCH is a parametric equivalent with identical voltage rating (600 V), current rating (15 A), forward voltage (1.1 V @ 15 A), recovery speed, reverse leakage (1 µA @ 600 V), and operating temperature range (-55 to 150 °C). The primary difference is AEC-Q101 automotive qualification on the S15JCH. Both parts are pin-compatible in the DO-214AB package and are RoHS3 compliant.

Q: Can the S8CJ-M3/I replace the S15JC in all applications?

A: No. The S8CJ-M3/I has a maximum average rectified current rating of 8 A, compared to 15 A for the S15JC. This part is suitable only for applications where the circuit current requirement does not exceed 8 A. The 600 V voltage rating and DO-214AB package are identical. Forward voltage is lower at rated current (985 mV @ 8 A), which may reduce power dissipation in current-limited designs.

Q: What is the primary limitation of the MURS360T3G as a substitute?

A: The MURS360T3G has a maximum average rectified current rating of 3 A, significantly lower than the S15JC's 15 A rating. This part is suitable only for low-current applications. The 600 V voltage rating and DO-214AB package match the S15JC. The MURS360T3G offers fast recovery characteristics (≤500 ns) and an extended operating temperature range (-65 to 175 °C), which may be beneficial in specific high-frequency or thermal applications, provided current requirements are satisfied.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The S15JCH, S8CJ-M3/I, and MURS360T3G are all RoHS3 compliant, matching the compliance status of the S15JC. All parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited) and are REACH Unaffected.

Q: Do all substitute parts use the same package?

A: Yes. All substitute parts use the DO-214AB (SMC) package, ensuring mechanical and electrical pin compatibility. Packaging format differs: S15JC, S15JCH, and S8CJ-M3/I are supplied in Tape & Reel (TR) format, while MURS360T3G is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging format compatibility with assembly equipment before procurement.

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

A: Recovery speed refers to the time required for the diode to transition from forward conduction to reverse blocking when the applied voltage reverses. The S15JC, S15JCH, and S8CJ-M3/I have standard recovery characteristics (>500 ns), while the MURS360T3G has fast recovery characteristics (≤500 ns). Fast recovery diodes reduce switching losses and EMI in high-frequency applications but may exhibit higher reverse leakage current. Selection depends on circuit operating frequency and thermal management requirements.

Q: Can I use the S15JCH in non-automotive applications?

A: Yes. The S15JCH is a parametric equivalent to the S15JC and is suitable for any application where the S15JC is specified. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in non-automotive designs. The S15JCH provides equivalent performance with enhanced reliability qualification.
