Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ14A-M3/52 are qualified based on the following electrical and mechanical parameters:

Critical Matching 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
• Type: Zener, Unidirectional (1 channel)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts maintain compatibility within the specified electrical performance window and physical package constraints. Variations in Voltage - Breakdown (Min) within the range 15.5V to 15.8V and operating temperature ranges from -55°C to -50°C minimum are acceptable within the SMBJ14 series specifications.

Parameter Comparison

Engineering Selection Recommendations

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

Packaging Availability: SMBJ14A-E3/52 is supplied in Cut Tape (CT) & Digi-Reel® format, while SMBJ14A-M3/52, SMBJ14D-M3/H, SMBJ14A-13-F, and SMBJ14A-TP are supplied in Tape & Reel (TR) format. Choose based on procurement and assembly line requirements.

Electrical Performance Tolerance: SMBJ14D-M3/H exhibits a clamping voltage of 22.9V (0.3V lower than the main part) and peak pulse current of 26.2A (0.3A higher). This part remains within acceptable substitution parameters for general-purpose TVS applications.

Temperature Range: SMBJ14A-TP supports an extended operating temperature range to 175°C, compared to 150°C for the main part and most substitutes. SMBJ14A (MDD) operates to a minimum of -50°C versus -55°C for other options. Select based on thermal environment requirements.

Inventory Availability: Substitute parts demonstrate varying stock levels. SMBJ14A-13-F (Diodes Incorporated) and SMBJ14A-TP (Micro Commercial Co) offer the highest inventory quantities at 41,400 and 40,403 pieces respectively.

Frequently Asked Questions (FAQ)

Q: Can SMBJ14D-M3/H be used as a direct replacement for SMBJ14A-M3/52?

A: Yes. SMBJ14D-M3/H is electrically compatible. The clamping voltage is 22.9V versus 23.2V, and peak pulse current is 26.2A versus 25.9A. Both parameters fall within acceptable tolerance for the SMBJ14 series. Both parts are Vishay TransZorb® devices in DO-214AA packaging with identical operating temperature range (-55°C to 150°C).

Q: What is the difference between SMBJ14A-E3/52 and SMBJ14A-M3/52?

A: The primary difference is packaging format. SMBJ14A-E3/52 is supplied in Cut Tape (CT) & Digi-Reel® format, while SMBJ14A-M3/52 is supplied in Tape & Reel (TR) format. Electrical specifications are identical: 14V reverse standoff, 23.2V clamping voltage, 25.9A peak pulse current, and 600W peak pulse power. Both are Vishay parts with ROHS3 compliance.

Q: Are MDD and Diodes Incorporated SMBJ14A parts compatible with Vishay SMBJ14A-M3/52?

A: Yes. MDD SMBJ14A and Diodes Incorporated SMBJ14A-13-F maintain the same electrical specifications: 14V reverse standoff, 23.2V clamping voltage, 25.8 to 25.9A peak pulse current, and 600W peak pulse power. All are surface mount DO-214AA/SMB packages with ROHS3 compliance and MSL 1 rating. Operating temperature ranges are -55°C to 150°C for Diodes Incorporated and -50°C to 150°C for MDD.

Q: Does SMBJ14A-TP have any advantages over SMBJ14A-M3/52?

A: SMBJ14A-TP (Micro Commercial Co) supports an extended operating temperature range to 175°C, compared to 150°C for SMBJ14A-M3/52. Electrical performance is equivalent: 14V reverse standoff, 23.2V clamping voltage, 25.8A peak pulse current, and 600W peak pulse power. Both use DO-214AA packaging and are ROHS3 compliant.

Q: Can these TVS diodes be used interchangeably in production assembly?

A: All listed substitute parts are mechanically and electrically compatible for surface mount assembly in DO-214AA/SMB packages. They maintain identical pinout, footprint, and solder reflow requirements. Electrical performance variations are within acceptable tolerance for general-purpose transient voltage suppression applications.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
