Substitute Part Grouping Explanation

Substitution of the SMBJ110AE3/TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 3.4A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1

Mechanical Equivalence Criteria:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts maintain identical electrical performance specifications and package compatibility. Variations in operating temperature range and packaging format (tape and reel versus cut tape) do not affect functional substitution within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—SMBJ110A (MDD), SMBJ110A-13-F (Diodes Incorporated), and SMBJ110A-E3/52 (Vishay General Semiconductor)—are functionally equivalent to the SMBJ110AE3/TR13 across all critical electrical and mechanical parameters. Each substitute maintains active product status and full compliance with RoHS3 and REACH regulations.

Selection Considerations Based on Provided Data:

The SMBJ110A-E3/52 (Vishay) offers the highest inventory availability at 45,300 pieces and is supplied on tape and reel, matching the original packaging format of the SMBJ110AE3/TR13. This part is designated as part of the TransZorb® series and maintains an operating temperature range of -55°C to 150°C.

The SMBJ110A-13-F (Diodes Incorporated) is supplied in cut tape and Digi-Reel® format with 4,700 pieces in stock and supports an operating temperature range of -55°C to 150°C.

The SMBJ110A (MDD) is available in the highest quantity at 47,400 pieces with an operating temperature range of -50°C to 150°C. Packaging format is not specified in the provided data.

All three substitutes are suitable for direct replacement in applications where the SMBJ110AE3/TR13 is currently specified, provided that the operating temperature requirements of the application fall within the stated ranges of the selected substitute.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110A (MDD) be used as a direct replacement for SMBJ110AE3/TR13?

A: Yes. The SMBJ110A (MDD) meets all critical electrical specifications: 110V reverse standoff voltage, 122V minimum breakdown voltage, 177V maximum clamping voltage, and 3.4A peak pulse current. Both parts are packaged in DO-214AA (SMB) format for surface mount applications and maintain RoHS3 compliance and MSL 1 rating. The operating temperature range of -50°C to 150°C is narrower than the original part's -65°C to 150°C range; verify application requirements before selection.

Q: What is the difference between SMBJ110A-13-F and SMBJ110A-E3/52?

A: Both parts are electrically identical with 110V standoff voltage, 177V clamping voltage, and 3.4A peak pulse current. The primary differences are manufacturer (Diodes Incorporated versus Vishay), packaging format (cut tape and Digi-Reel® versus tape and reel), and inventory availability (4,700 versus 45,300 pieces). Operating temperature ranges differ slightly: -55°C to 150°C for both. Select based on packaging requirements and supply chain availability.

Q: Are all substitute parts compatible with the original PCB layout?

A: Yes. All substitute parts use the DO-214AA (SMB) package format with identical mechanical dimensions and pin configuration. No PCB layout modifications are required for substitution.

Q: Does the operating temperature range difference affect substitution suitability?

A: Operating temperature range differences must be evaluated against application requirements. The SMBJ110AE3/TR13 operates from -65°C to 150°C. The SMBJ110A (MDD) operates from -50°C to 150°C, while SMBJ110A-13-F and SMBJ110A-E3/52 operate from -55°C to 150°C. If the application requires operation below -50°C, only the original part or the -55°C variants are suitable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts—SMBJ110A (MDD), SMBJ110A-13-F (Diodes Incorporated), and SMBJ110A-E3/52 (Vishay)—are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: Which substitute part offers the best supply availability?

A: The SMBJ110A (MDD) offers the highest inventory at 47,400 pieces. The SMBJ110A-E3/52 (Vishay) provides 45,300 pieces and maintains tape and reel packaging matching the original format. The SMBJ110A-13-F (Diodes Incorporated) has 4,700 pieces available in cut tape and Digi-Reel® format.
