S15GC Equivalent & Substitute Parts

Part Overview

The S15GC is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 15 A average rectified current. The device is packaged in DO-214AB (SMC) surface mount configuration and is classified as Active product status. This diode is suitable for standard recovery applications requiring moderate voltage and current ratings in compact surface mount form factors. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate specific application requirements such as automotive qualification or alternative sourcing options.

Substitute Part Grouping Explanation

Substitute parts for the S15GC are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 15 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 15 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 µA @ 400 V
• Capacitance @ Vr, F: 93 pF @ 4V, 1MHz

Mechanical Parameters:

• Package / Case: DO-214AB, SMC
• Operating Temperature - Junction: -55°C to 150°C
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Additional qualifications such as automotive certification (AEC-Q101) represent enhanced product variants suitable for specific application domains.

Engineering Selection Recommendations

S15GC Selection Criteria: The S15GC is suitable for general-purpose rectification applications requiring 400 V, 15 A performance in surface mount DO-214AB packaging. The device maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and assembly processes.

S15GCH Selection Criteria: The S15GCH is a parametric equivalent to the S15GC with identical electrical and mechanical specifications. The S15GCH carries AEC-Q101 automotive qualification, designating it for automotive-grade applications. Selection of S15GCH is appropriate when automotive reliability standards, enhanced qualification documentation, or automotive supply chain requirements are specified. Both parts share identical core performance parameters and package configuration, enabling direct substitution based on application requirements and qualification mandates.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with lead-free soldering processes and standard storage conditions without desiccant requirements.

Frequently Asked Questions (FAQ)

Q: Can S15GCH be used as a direct replacement for S15GC? A: Yes. The S15GCH is a parametric equivalent with identical electrical ratings (400 V, 15 A), forward voltage characteristics (1.1 V @ 15 A), recovery speed, reverse leakage current, and capacitance specifications. Both devices use the same DO-214AB (SMC) surface mount package and operate across the identical temperature range (-55°C to 150°C). Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the primary difference between S15GC and S15GCH? A: The S15GCH includes AEC-Q101 automotive qualification, while the S15GC does not carry this designation. All electrical parameters, mechanical specifications, and compliance ratings (ROHS3, MSL Level 1) are identical. The qualification difference reflects the intended application domain and supply chain requirements rather than performance characteristics.

Q: Are both parts suitable for automotive applications? A: The S15GCH carries AEC-Q101 automotive qualification and is designated for automotive-grade applications. The S15GC is classified as a general-purpose device without automotive qualification. Selection between the two depends on whether automotive qualification documentation and reliability standards are required by the application specification.

Q: Do both parts require special storage or handling? A: No. Both S15GC and S15GCH carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage conditions are sufficient without desiccant packaging or controlled humidity requirements.

Q: Are the parts compatible with lead-free soldering processes? A: Yes. Both S15GC and S15GCH are ROHS3 compliant, confirming compatibility with lead-free soldering processes and RoHS-regulated manufacturing environments.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Both parts use identical DO-214AB (SMC) surface mount packaging with the same footprint, pin configuration, and thermal characteristics. PCB layouts and assembly processes require no modification when substituting between S15GC and S15GCH.
