Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ110CA-M3/5B is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V or higher
• Voltage - Clamping (Max) @ Ipp: 177V or lower
• Current - Peak Pulse (10/1000µs): 3.4A or higher
• Power - Peak Pulse: 600W or higher
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -55°C to 150°C (TJ)

Identified Substitute Parts:

1. SMBJ110CA-E3/52 (Vishay General Semiconductor - Diodes Division): Identical electrical specifications with alternative packaging designation (Tape & Reel variant).

2. SMBJ110CD-M3/I (Vishay General Semiconductor - Diodes Division): Meets substitution criteria with minor parameter variations within acceptable tolerance (Voltage - Clamping Max @ Ipp: 174V; Current - Peak Pulse: 3.45A; Voltage - Breakdown Min: 124V).

3. SMBJ110CA (Fairchild Semiconductor): Identical electrical specifications with alternative packaging format (Bulk packaging instead of Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

SMBJ110CA-E3/52 (Vishay): This substitute provides identical electrical performance to the main part number with full compliance documentation (RoHS3, REACH Unaffected, MSL 1). The difference lies in packaging designation (E3/52 variant versus M3/5B variant), both supplied in Tape & Reel format. Selection is appropriate for applications requiring Vishay sourcing continuity and certified compliance status.

SMBJ110CD-M3/I (Vishay): This substitute operates within acceptable parameter tolerances. Voltage - Clamping (Max) @ Ipp is 174V (3V lower than main part), Voltage - Breakdown (Min) is 124V (2V higher), and Current - Peak Pulse is 3.45A (0.05A higher). All parameters remain within functional equivalence for general-purpose TVS applications. Full compliance documentation is provided (RoHS3, REACH Unaffected, MSL 1). Selection is appropriate when this variant offers superior inventory availability.

SMBJ110CA (Fairchild Semiconductor): This substitute provides identical electrical specifications to the main part. The primary distinction is packaging format (Bulk versus Tape & Reel). Compliance documentation (RoHS, REACH, MSL) is not specified in available data. Selection requires verification of compliance requirements for the target application and confirmation of Fairchild sourcing acceptability in procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110CA-E3/52 be used as a direct replacement for SMBJ110CA-M3/5B?

A: Yes. Both parts are manufactured by Vishay General Semiconductor - Diodes Division with identical electrical specifications (110V standoff, 177V clamping, 3.4A peak pulse, 600W peak power). The designation difference (E3/52 versus M3/5B) reflects packaging tape configuration variants, both supplied in Tape & Reel format. Both maintain identical compliance status (RoHS3, REACH Unaffected, MSL 1).

Q: What are the electrical differences between SMBJ110CD-M3/I and SMBJ110CA-M3/5B?

A: SMBJ110CD-M3/I exhibits three parameter variations: Voltage - Clamping (Max) @ Ipp is 174V versus 177V (3V lower), Voltage - Breakdown (Min) is 124V versus 122V (2V higher), and Current - Peak Pulse is 3.45A versus 3.4A (0.05A higher). These variations remain within functional equivalence for general-purpose transient voltage suppression. All other parameters are identical.

Q: Is the Fairchild SMBJ110CA suitable for applications requiring RoHS3 compliance?

A: Compliance documentation for the Fairchild SMBJ110CA is not specified in available technical data. Confirmation of RoHS3 compliance status must be obtained directly from Fairchild Semiconductor or the component supplier before selection for applications with mandatory compliance requirements.

Q: What is the difference between Tape & Reel and Bulk packaging for these TVS diodes?

A: Tape & Reel packaging (SMBJ110CA-M3/5B, SMBJ110CA-E3/52, SMBJ110CD-M3/I) supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Bulk packaging (SMBJ110CA from Fairchild) supplies components in loose form, typically in trays or bags. Electrical performance is identical; packaging selection depends on assembly process requirements and procurement volume.

Q: Can these TVS diodes be used interchangeably in high-temperature applications?

A: Yes. All listed parts (main and substitutes) maintain identical operating temperature range specifications: -55°C to 150°C (TJ). Selection among these parts does not affect thermal performance capability.

Q: What inventory considerations apply when selecting among these substitutes?

A: Current inventory levels are: SMBJ110CA-M3/5B (1,109 pcs), SMBJ110CA-E3/52 (3,825 pcs), SMBJ110CD-M3/I (12,652 pcs), and SMBJ110CA Fairchild (44,300 pcs). Substitute selection may be driven by inventory availability and lead time requirements while maintaining electrical and mechanical compatibility.
