Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the SMB10J28A-M3/5B are determined by strict alignment of the following critical electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 28V
• Voltage - Breakdown (Min): 31.1V
• Voltage - Clamping (Max) @ Ipp: 45.4V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

Acceptable Variation Parameters:

• Current - Peak Pulse (10/1000µs): 13.2A to 22A (all substitute parts operate within acceptable pulse current specifications)
• Power - Peak Pulse: 600W to 1000W (all substitute parts meet or exceed minimum power dissipation requirements)
• Operating Temperature Range: -65°C to -50°C minimum; 150°C to 175°C maximum (all substitute parts cover the primary operating range)

All identified substitute parts maintain identical voltage specifications and package form factor, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence with the SMB10J28A-M3/5B across critical voltage parameters and package specifications. Selection among these alternatives should be based on the following factors:

Supply Chain Availability: The SZ1SMB28AT3G (Littelfuse) offers the highest inventory level at 143,959 units. The SMBJ28A (MDD) provides 86,300 units. The SMBJ28A-13-F (Diodes Incorporated) and SMBJ28A-TP (Micro Commercial Co) offer 20,100 and 30,400 units respectively.

Compliance and Certification: The SZ1SMB28AT3G carries AEC-Q101 automotive qualification and operates across an extended temperature range (-65°C to 150°C), making it suitable for automotive and high-reliability applications. All parts maintain ROHS3 compliance and MSL 1 rating.

Temperature Performance: The SMBJ28A-TP (Micro Commercial Co) supports the highest maximum operating temperature at 175°C. The SZ1SMB28AT3G (Littelfuse) supports the lowest minimum operating temperature at -65°C.

Power Dissipation: The SMB10J28A-M3/5B provides 1000W peak pulse power. Substitute parts provide 600W peak pulse power, which remains adequate for general purpose transient suppression applications where the original 22A peak pulse current specification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can SMBJ28A-13-F replace SMB10J28A-M3/5B directly in my circuit?

A: Yes. The SMBJ28A-13-F maintains identical voltage specifications (28V standoff, 31.1V breakdown, 45.4V clamping) and uses the same DO-214AA SMB package. The primary difference is peak pulse current (13.2A versus 22A) and power dissipation (600W versus 1000W). Direct substitution is valid if your circuit does not require the higher current or power specifications of the original part.

Q: What is the difference between the packaging formats listed?

A: Tape & Reel (TR) packaging is standard for automated assembly processes. Cut Tape (CT) and Digi-Reel® formats provide alternative packaging options. All formats contain the same component in the DO-214AA SMB package and are functionally equivalent.

Q: Is the SZ1SMB28AT3G suitable for automotive applications?

A: Yes. The SZ1SMB28AT3G carries AEC-Q101 automotive qualification, making it appropriate for automotive-grade applications. Other substitute parts are not explicitly qualified for automotive use.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the SMB10J28A-M3/5B.

Q: What is the impact of lower peak pulse current in substitute parts?

A: Substitute parts rated at 13.2A to 13.3A peak pulse current (versus 22A in the original) are suitable for applications where transient energy levels do not exceed the 600W power dissipation limit. If your design requires the full 22A capability, the SMB10J28A-M3/5B should be retained.
