SMBJ6.5A-M3/52 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SMBJ6.5A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AA (SMB) package and provides transient overvoltage protection for general-purpose applications. The part is classified as Active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the SMBJ6.5 base product family.

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ6.5A-M3/52 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 53.6A or higher
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C (TJ)
• Type: Zener, Unidirectional (1 channel)

Mechanical Compatibility Criteria:

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

All identified substitute parts maintain identical electrical performance specifications and mechanical form factors. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) do not affect electrical or mechanical compatibility and represent logistics-level differences only.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical equivalence to the SMBJ6.5A-M3/52. Selection among these alternatives is based on the following factors:

Manufacturer Recommendation: SMBJ6.5A-E3/52 (Vishay) is the manufacturer-recommended equivalent, maintaining identical specifications and sourced from the same manufacturer as the primary part. This option provides continuity in supply chain qualification and design validation.

Peak Pulse Current Consideration: The SMBJ6.5A from Taiwan Semiconductor Corporation provides a marginally higher peak pulse current rating of 56A compared to 53.6A in other variants. This represents a 4.5% increase in transient current handling capacity while maintaining all other electrical parameters. This part is suitable for applications requiring maximum transient margin within the SMBJ6.5 family.

Packaging Format: All parts are available in surface mount DO-214AA (SMB) package. Packaging format differences (Tape & Reel, Cut Tape, Digi-Reel) are logistics considerations and do not affect electrical performance or mechanical compatibility.

Compliance & Certification: All substitute parts carry identical RoHS3 compliance, MSL 1 rating, and REACH Unaffected status. All parts are classified as Active products with no end-of-life concerns.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A-E3/52 be used as a direct replacement for SMBJ6.5A-M3/52?

A: Yes. SMBJ6.5A-E3/52 is electrically and mechanically equivalent to SMBJ6.5A-M3/52. Both are manufactured by Vishay and share identical electrical specifications. The difference is packaging format: M3/52 uses Tape & Reel, while E3/52 uses Cut Tape & Digi-Reel. This does not affect component performance.

Q: What is the difference between the Vishay SMBJ6.5A-M3/52 and the Taiwan Semiconductor SMBJ6.5A?

A: Both parts meet the same voltage and clamping specifications (6.5V standoff, 11.2V clamp). The Taiwan Semiconductor version provides a slightly higher peak pulse current rating of 56A versus 53.6A. All other electrical and mechanical parameters are identical. Both are RoHS3 compliant and Active status.

Q: Is the Diodes Incorporated SMBJ6.5A-13-F compatible with the original SMBJ6.5A-M3/52?

A: Yes. SMBJ6.5A-13-F from Diodes Incorporated is electrically and mechanically equivalent. It maintains the same 6.5V standoff voltage, 11.2V clamping voltage, 53.6A peak pulse current, and DO-214AA SMB package. All compliance certifications match.

Q: Does packaging format affect electrical performance?

A: No. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) are supply chain and handling considerations only. They do not affect electrical characteristics, thermal performance, or mechanical compatibility of the TVS diode.

Q: Are all substitute parts suitable for the same circuit applications?

A: Yes. All identified substitute parts are rated for general-purpose transient voltage suppression with identical electrical specifications. They are interchangeable in any circuit designed for the SMBJ6.5A-M3/52.

Q: What compliance certifications apply to all substitute parts?

A: All parts are RoHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. All parts maintain Active product status with no planned obsolescence.
