SMBJ6.5A-M3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ6.5A-M3/5B 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 Active status and ROHS3 compliant, making it suitable for modern electronic designs requiring surge suppression across a 6.5V nominal operating range. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ6.5A-M3/5B are qualified based on the following electrical and mechanical 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)
Mounting Type: Surface Mount
Package / Case: DO-214AA or SMB
Type: Zener
Unidirectional Channels: 1
RoHS Status: ROHS3 Compliant

All substitute parts maintain identical voltage specifications and thermal operating range. Packaging variations (Tape & Reel, Cut Tape, Digi-Reel) do not affect electrical performance and represent alternative supply formats. Peak pulse current specifications of 56A or 53.6A both satisfy the protection requirements within the 600W power dissipation envelope.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring compatibility with current manufacturing standards and environmental regulations. The SMBJ6.5A-E3/52 from Vishay provides direct electrical equivalence with identical specifications and represents the closest substitute from the original manufacturer. The SMBJ6.5A from Taiwan Semiconductor Corporation offers a 56A peak pulse current specification, which exceeds the minimum requirement and provides additional margin within the 600W power envelope. The SMBJ6.5A-13-F from Diodes Incorporated delivers equivalent performance in Tape & Reel packaging. The SMBJ6V5A from Taiwan Semiconductor Corporation provides identical electrical performance in Cut Tape format with Digi-Reel® supply option.

Selection between these substitutes depends on packaging format availability, supply chain requirements, and inventory status rather than electrical performance differences. All parts are qualified for the same thermal operating range and voltage protection specifications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A-M3/5B be replaced with SMBJ6.5A from Taiwan Semiconductor Corporation?

A: Yes. Both parts maintain identical voltage specifications (6.5V reverse standoff, 7.22V breakdown, 11.2V clamping) and thermal operating range (-55°C to 150°C). The Taiwan Semiconductor version provides 56A peak pulse current compared to 53.6A, which represents additional performance margin within the 600W power dissipation limit. Both are ROHS3 compliant and surface mount in DO-214AA/SMB package.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel and Cut Tape are supply format variations that do not affect electrical performance or mechanical compatibility. Tape & Reel provides continuous reel packaging for automated assembly lines. Cut Tape and Digi-Reel® formats offer alternative supply options for different manufacturing processes. All formats are compatible with standard surface mount assembly equipment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can packaging format be mixed in a single design?

A: Yes. Since packaging format does not affect electrical performance or mechanical fit in the DO-214AA/SMB footprint, different packaging formats can be used interchangeably within the same circuit design. Assembly process compatibility should be verified with manufacturing equipment specifications.

Q: What determines substitution eligibility for SMBJ6.5A-M3/5B?

A: Substitution eligibility is determined by matching voltage specifications (6.5V reverse standoff, 7.22V breakdown minimum, 11.2V clamping maximum), peak pulse current rating of 53.6A or higher, 600W power dissipation capability, surface mount DO-214AA/SMB package compatibility, and -55°C to 150°C operating temperature range. All listed parts meet these criteria.
