Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V or 9.1V (within 1.1% tolerance)
• Current - Peak Pulse: 65.2A or 65.3A or 65.9A (within 1% tolerance)
• Power - Peak Pulse: 600W (exact match)
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Mounting Type: Surface Mount (required)
• Type: Zener, Bidirectional (functional equivalence)

Secondary Compatibility Parameters:

• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling compatibility)
• Operating Temperature Range: -55°C minimum and 150°C maximum or broader (thermal compatibility)

Parts meeting all primary parameters and secondary compatibility requirements are classified as direct substitutes. Packaging format variations (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical or mechanical substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements for new designs and production environments. Selection among equivalent parts should be based on:

Inventory Availability: MDD SMBJ5.0CA offers the highest stock level (49305 Pcs), followed by Vishay SMBJ5.0CA-E3/52 (33086 Pcs). These options provide supply chain stability for high-volume applications.

Manufacturer Consistency: Vishay General Semiconductor - Diodes Division parts (SMBJ5.0CA-M3/5B, SMBJ5.0CA-E3/52, SMBJ5.0CD-M3/I, SMBJ5.0CA-E3/5B) maintain identical electrical specifications and are sourced from the original design manufacturer.

Temperature Range Consideration: Micro Commercial Co SMBJ5.0CA-TP supports extended operating temperature to 175°C, providing margin for high-temperature applications. Central Semiconductor Corp 1SMB5.0CA TR13 PBFREE and MDD SMBJ5.0CA support -65°C minimum, extending low-temperature capability.

Clamping Voltage Tolerance: Vishay SMBJ5.0CD-M3/I exhibits 9.1V clamping voltage (0.1V lower than primary specification) with proportionally higher peak pulse current (65.9A). This part remains functionally equivalent within standard TVS diode tolerance bands.

Frequently Asked Questions (FAQ)

Q: Can SMBJ5.0CD-M3/I be used as a direct replacement for SMBJ5.0CA-M3/5B?

A: Yes. The SMBJ5.0CD-M3/I maintains identical reverse standoff voltage (5V), power rating (600W), and package specification (DO-214AA, SMB). The clamping voltage differential of 0.1V (9.1V vs. 9.2V) and peak pulse current increase of 0.7A fall within standard component tolerance ranges for TVS diode applications.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape & Digi-Reel) significant for substitution?

A: No. Packaging format variations affect only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical. Both formats are compatible with standard surface mount assembly equipment.

Q: Which substitute part offers the best supply chain position?

A: MDD SMBJ5.0CA provides the highest inventory level at 49305 Pcs. For Vishay-sourced alternatives, SMBJ5.0CA-E3/52 maintains 33086 Pcs in stock.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8541.10.0080. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts.

Q: What is the temperature range consideration for substitute selection?

A: The original SMBJ5.0CA-M3/5B operates -55°C to 150°C. Substitute parts maintain this range or extend it. SMBJ5.0CA-TP extends to 175°C; MDD and Central Semiconductor variants extend to -65°C minimum. Selection depends on application thermal requirements.

Q: Are there any electrical performance differences between manufacturers?

A: All parts maintain 5V reverse standoff voltage, 600W peak pulse power, and 65.2A to 65.9A peak pulse current specifications. Variations within this range are within standard TVS diode manufacturing tolerances and do not affect circuit protection performance.
