Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ17CA-M3/9AT are qualified based on the following critical parameters that must remain constant or within acceptable operating ranges:

Mandatory Matching Parameters:

• Voltage - Reverse Standoff (Typ): 17V
• Voltage - Breakdown (Min): 18.9V
• Voltage - Clamping (Max) @ Ipp: 27.6V
• Type: Zener, Bidirectional
• Bidirectional Channels: 1
• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): Substitutes may exceed the 54.3A specification, as higher current ratings provide equivalent or enhanced performance
• Power - Peak Pulse: Substitutes may exceed the 1500W specification, as higher power ratings provide equivalent or enhanced performance
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) are interchangeable for component procurement

Substitute parts meeting these criteria maintain electrical compatibility and mechanical interchangeability with the original SMCJ17CA-M3/9AT specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): SMCJ17CA-E3/57T from Vishay General Semiconductor - Diodes Division is the direct equivalent to SMCJ17CA-M3/9AT. Both parts share identical electrical specifications and differ only in packaging format (Cut Tape versus Tape & Reel). This part maintains Active product status and ROHS3 compliance.

Compatible Substitutes (Higher Performance): SMDJ17CA (Alpha & Omega Semiconductor Inc.) and 5.0SMDJ17CA (MDE Semiconductor Inc) are compatible substitutes that exceed the original specification in current and power handling capacity. Both maintain the required voltage parameters, operating temperature range, and RoHS3 compliance. These parts provide enhanced transient suppression capability within the same package footprint.

SMCJ17CA-13-F (Diodes Incorporated) is a compatible substitute with equivalent current and power specifications. This part maintains Active product status and ROHS3 compliance.

Limited Information: SMCJ17CA from Fairchild Semiconductor is listed as a substitute but lacks detailed electrical parameter specifications in the provided data. Verification of electrical characteristics against the original specification is required before selection.

All substitute parts maintain Active product status, ROHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can SMCJ17CA-E3/57T be used as a direct replacement for SMCJ17CA-M3/9AT? A: Yes. SMCJ17CA-E3/57T is a direct equivalent with identical electrical specifications. The difference is packaging format: SMCJ17CA-E3/57T is supplied in Cut Tape (CT) format while SMCJ17CA-M3/9AT is supplied in Tape & Reel (TR) format. Both formats are compatible for component placement and soldering.

Q: What is the difference between SMDJ17CA and SMCJ17CA-M3/9AT? A: Both parts share identical voltage specifications (17V reverse standoff, 27.6V clamping) and operating temperature range. SMDJ17CA provides higher peak pulse current (108.7A versus 54.3A) and higher peak pulse power (3000W versus 1500W). This makes SMDJ17CA suitable for applications requiring enhanced transient suppression capability within the same voltage class.

Q: Can 5.0SMDJ17CA replace SMCJ17CA-M3/9AT in my circuit? A: Yes, provided your circuit design permits the higher performance specifications. 5.0SMDJ17CA maintains the same voltage parameters and operating temperature range but provides significantly higher peak pulse current (181A) and power (5000W). The component is mechanically and electrically compatible in the DO-214AB SMC package.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Q: What packaging formats are available for these TVS diodes? A: The SMCJ17CA-M3/9AT is supplied in Tape & Reel (TR) format. SMCJ17CA-E3/57T is available in Cut Tape (CT) format. Other substitutes are available in Tape & Reel (TR) format. All formats are compatible for automated component placement and soldering operations.

Q: Can I use SMCJ17CA from Fairchild Semiconductor as a substitute? A: SMCJ17CA from Fairchild Semiconductor is listed as a substitute but detailed electrical parameter specifications are not provided in the available data. Verification of electrical characteristics against the original SMCJ17CA-M3/9AT specification is required before selection for critical applications.
