Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ7.0CD-M3/H is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Clamping (Max) @ Ipp: Maximum 12V (allows tolerance variation from 11.8V)
• Current - Peak Pulse (10/1000µs): 50A or higher
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Product Status: Active
• RoHS3 Compliance: Required

All identified substitute parts meet these criteria and are classified as Active products with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active products with full RoHS3 compliance and REACH unaffected status, matching the regulatory posture of the SMBJ7.0CD-M3/H. Selection among substitutes should be based on:

• Packaging format availability: SMBJ7.0CA-E3/52 is supplied in Cut Tape (CT); SMBJ7.0CA and SMBJ7.0CA-13-F are supplied in Tape & Reel (TR)
• Manufacturer preference and supply chain considerations
• Operating temperature minimum requirement: SMBJ7.0CA specifies -50°C minimum versus -55°C for other options
• Inventory availability and lead time requirements

All parts maintain equivalent electrical performance within the SMBJ7.0 series specification envelope.

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.0CA-E3/52 be used as a direct replacement for SMBJ7.0CD-M3/H?

A: Yes. Both parts share identical reverse standoff voltage (7V), equivalent clamping voltage (12V vs 11.8V), matching peak pulse current (50A vs 50.8A), and identical power dissipation (600W). The primary difference is packaging format: SMBJ7.0CA-E3/52 is supplied in Cut Tape while SMBJ7.0CD-M3/H is supplied in Tape & Reel.

Q: What is the difference between SMBJ7.0CA and SMBJ7.0CA-13-F?

A: Both parts are electrically equivalent with 7V reverse standoff, 12V clamping voltage, and 50A peak pulse current. The primary differences are manufacturer (MDD versus Diodes Incorporated) and operating temperature minimum specification (SMBJ7.0CA: -50°C; SMBJ7.0CA-13-F: -55°C). For applications requiring operation below -50°C, SMBJ7.0CA-13-F is the appropriate selection.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the DO-214AA (SMB) package with identical mechanical dimensions and pin configuration, ensuring direct PCB footprint compatibility.

Q: What regulatory certifications apply to all listed parts?

A: All parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080.

Q: Can SMBJ7.0CA be used in applications requiring -55°C operation?

A: No. SMBJ7.0CA specifies a minimum operating temperature of -50°C. For applications requiring -55°C operation, use SMBJ7.0CD-M3/H, SMBJ7.0CA-E3/52, or SMBJ7.0CA-13-F.
