Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ100A-M3/52 are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 100V
• Voltage - Breakdown (Min): 111V minimum
• Voltage - Clamping (Max) @ Ipp: 162V maximum
• Current - Peak Pulse (10/1000µs): 3.7A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitutes maintain these core electrical specifications and physical package requirements, ensuring functional equivalence in general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, meeting regulatory requirements for current applications. Selection among these equivalents should be based on:

• Packaging format availability (Tape & Reel vs. Cut Tape & Digi-Reel®)
• Operating temperature range requirements (note that SMBJ100A-TP extends to 175°C)
• Inventory availability and lead time
• Supplier qualification and procurement agreements

The SMBJ100D-M3/H variant exhibits slightly different clamping voltage (159V vs. 162V) and breakdown voltage (113V vs. 111V), with marginally higher peak pulse current (3.77A vs. 3.7A). These variations remain within acceptable tolerance for general-purpose transient suppression but should be verified against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ100D-M3/H be used as a direct replacement for SMBJ100A-M3/52?

A: SMBJ100D-M3/H is electrically compatible for general-purpose applications. The clamping voltage is 159V versus 162V, and breakdown voltage is 113V versus 111V. Both maintain the same reverse standoff voltage (100V) and peak pulse current (3.7A minimum). Verify circuit tolerance for the 3V clamping voltage difference before substitution.

Q: What is the difference between packaging designations TR, CT, and Digi-Reel®?

A: TR (Tape & Reel) and CT (Cut Tape) & Digi-Reel® refer to supply format. TR provides continuous reel packaging for automated assembly. CT & Digi-Reel® offers cut tape format with reel availability. Both formats contain identical components; selection depends on assembly equipment and order quantity requirements.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original SMBJ100A-M3/52 specifications.

Q: Does operating temperature range affect substitution suitability?

A: The SMBJ100A-M3/52 operates from -55°C to 150°C. The MDD variant operates from -50°C to 150°C, and SMBJ100A-TP extends to 175°C. For applications requiring the full -55°C lower limit, use Vishay, Diodes Incorporated, or Micro Commercial Co variants. For applications requiring extended upper temperature operation, SMBJ100A-TP is suitable.

Q: Can I mix manufacturers in the same design?

A: All listed parts maintain identical electrical specifications for the core parameters (100V standoff, 111V minimum breakdown, 162V clamping, 3.7A peak pulse, 600W peak power). Mixing manufacturers is acceptable provided procurement, qualification, and traceability procedures are followed per your organization's standards.
