Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ14CA-M3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 14V
• Voltage - Clamping (Max) @ Ipp: 23.2V ± tolerance
• Current - Peak Pulse (10/1000µs): 25.8A to 26.2A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to -50°C minimum; 150°C maximum
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain electrical equivalence within the specified parameter ranges and are compatible with the same PCB footprint and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and MSL 1 rating, meeting the same environmental and regulatory requirements as the primary part. Selection among these equivalents should be based on:

• Packaging format requirements: SMBJ14CA-E3/52 is supplied in Cut Tape (CT) & Digi-Reel® format; SMBJ14CA-M3/52 and SMBJ14CA-13-F are supplied in Tape & Reel (TR) format; SMBJ14CD-M3/H is supplied in Tape & Reel (TR) format; MDD SMBJ14CA has unspecified packaging.
• Inventory availability: MDD SMBJ14CA offers the highest stock level at 30,100 units; Vishay SMBJ14CA-E3/52 provides 11,550 units.
• Clamping voltage tolerance: SMBJ14CD-M3/H exhibits a slightly lower maximum clamping voltage of 22.9V compared to 23.2V for other equivalents.
• Operating temperature minimum: MDD SMBJ14CA operates from -50°C minimum, compared to -55°C for other options.

Frequently Asked Questions (FAQ)

Q: Can SMBJ14CD-M3/H be used as a direct replacement for SMBJ14CA-M3/52?

A: Yes. Both parts share identical reverse standoff voltage (14V), peak pulse power (600W), package format (DO-214AA, SMB), and operating temperature range (-55°C to 150°C). The clamping voltage difference of 0.3V (22.9V vs. 23.2V) falls within acceptable substitution tolerance for general-purpose TVS applications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) is standard reel packaging for automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume orders and mixed component picking. Both formats contain identical components; packaging selection depends on procurement volume and assembly line requirements.

Q: Is the MDD SMBJ14CA suitable for applications requiring -55°C operation?

A: The MDD SMBJ14CA operates from -50°C minimum, not -55°C. If your application requires -55°C operation, select SMBJ14CA-M3/52, SMBJ14CD-M3/H, SMBJ14CA-E3/52, or SMBJ14CA-13-F instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part's environmental qualifications.

Q: What determines electrical equivalence for TVS diode substitution?

A: Electrical equivalence is established by matching reverse standoff voltage (14V), clamping voltage range (23.2V ± tolerance), peak pulse current (25.8A to 26.2A), and peak pulse power (600W). All listed parts meet these criteria within specified tolerances.
