SMBJ64CA-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ64CA-M3/52 is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AA (SMB) package and is designed for general-purpose transient voltage suppression applications. The part is Active status and RoHS3 compliant, making it suitable for modern electronic designs requiring ESD and surge protection.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple manufacturers is needed to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ64CA-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Clamping (Max) @ Ipp: 103V ± 1V tolerance
• Current - Peak Pulse (10/1000µs): 5.8A ± 0.08A tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Type: Zener, Bidirectional, 1 Channel

Substitute parts must maintain identical electrical performance within the specified tolerances and be compatible with the same PCB footprint and reflow soldering process. Packaging format (Tape & Reel, Cut Tape, or bulk) does not affect electrical equivalence but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance for new designs.

SMBJ64CA-E3/52 (Vishay) is the manufacturer-recommended primary substitute, offering identical electrical specifications to the main part with significantly higher inventory availability (45,300 units). This part is suitable for direct replacement in all applications.

SMBJ64CA-M3/52 and SMBJ64CA-E3/52 are functionally equivalent Vishay variants differing only in packaging format (Tape & Reel designation). Selection between these should be based on procurement and assembly requirements rather than electrical performance.

SMBJ64CD-M3/H (Vishay) presents a minor electrical variation with clamping voltage of 102V (versus 103V) and peak pulse current of 5.88A (versus 5.8A). This part remains within acceptable substitution parameters for general-purpose transient suppression applications.

SMBJ64CA (Meritek) and SMBJ64CA-13-F (Diodes Incorporated) are cross-manufacturer equivalents with identical 103V clamping voltage and 5.8A peak pulse current specifications. These parts are suitable for applications requiring multi-source qualification or when Vishay parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64CD-M3/H be used as a direct replacement for SMBJ64CA-M3/52?

A: Yes. The SMBJ64CD-M3/H operates within acceptable substitution parameters. The clamping voltage is 102V (compared to 103V) and peak pulse current is 5.88A (compared to 5.8A). Both values remain within the functional tolerance band for general-purpose TVS diode applications. Both parts share identical reverse standoff voltage (64V), power rating (600W), package (DO-214AA, SMB), and operating temperature range (-55°C ~ 150°C).

Q: What is the difference between SMBJ64CA-M3/52 and SMBJ64CA-E3/52?

A: These are Vishay variants with identical electrical specifications. The difference lies in packaging format: SMBJ64CA-M3/52 is supplied in Tape & Reel (TR) format, while SMBJ64CA-E3/52 is also supplied in Tape & Reel format. Selection should be based on procurement availability and assembly line requirements. SMBJ64CA-E3/52 has significantly higher inventory availability.

Q: Are cross-manufacturer substitutes (Meritek, Diodes Incorporated) electrically equivalent?

A: Yes. SMBJ64CA (Meritek) and SMBJ64CA-13-F (Diodes Incorporated) meet the electrical specifications of the main part: 64V reverse standoff voltage, 103V clamping voltage, 5.8A peak pulse current, and 600W power rating. All parts are RoHS3 compliant with MSL 1 rating. Cross-manufacturer substitution is valid when Vishay parts are unavailable or when multi-source qualification is required.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only procurement, storage, and assembly workflow. Electrical performance, reliability, and functional characteristics remain identical regardless of whether the part is supplied in Tape & Reel (TR) or Cut Tape (CT) format. Selection should be based on assembly equipment compatibility and inventory management requirements.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use the identical DO-214AA (SMB) package and surface mount footprint. No PCB layout modifications are required. Reflow soldering parameters remain unchanged. Direct substitution is possible without design revision.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are RoHS3 compliant and REACH unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage or handling. All parts carry ECCN EAR99 classification and HTSUS 8541.10.0080 tariff code.
