SMBJ6.5A-E3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ6.5A-E3/5B 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 is designed for general-purpose transient voltage protection applications. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ6.5A-E3/5B are classified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS3 Compliance

Direct Equivalents maintain identical electrical specifications and package configuration. These parts are interchangeable without circuit redesign.

Functional Equivalents maintain the same reverse standoff voltage and clamping voltage but may vary in peak pulse current rating within acceptable operational margins. These parts are suitable for applications where the specified current rating provides adequate margin above actual circuit requirements.

Alternative Manufacturer Variants are produced by different manufacturers but meet the same electrical and mechanical specifications, offering supply chain flexibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical & Mechanical Specifications):

• SMBJ6.5A-E3/52 (Vishay): Identical specifications, alternative packaging format (Cut Tape vs. Tape & Reel)
• SMBJ6.5A-13-F (Diodes Incorporated): Identical electrical performance and package
• SMBJ6V5A (Taiwan Semiconductor Corporation): Identical electrical performance and package

Functional Equivalents (Matching Voltage Parameters, Current Variation):

• SMBJ6.5A (Taiwan Semiconductor Corporation): Peak pulse current 56A vs. 53.6A; maintains voltage specifications
• SMBJ6.5A-TR (STMicroelectronics): Peak pulse current 56A vs. 53.6A; maintains voltage specifications

Alternative Performance Profile:

• SM6T7V5A (STMicroelectronics): Reverse standoff voltage 6.4V (vs. 6.5V), clamping voltage 14.5V (vs. 11.2V), peak pulse current 276A (8/20µs). This part operates at higher clamping voltage and current rating; selection requires circuit-level evaluation.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and -55°C to 150°C operating temperature range. Selection among direct substitutes is based on packaging format availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A-E3/52 replace SMBJ6.5A-E3/5B directly? A: Yes. Both parts are manufactured by Vishay with identical electrical specifications (6.5V reverse standoff, 11.2V clamping, 53.6A peak pulse). The difference is packaging format: SMBJ6.5A-E3/5B is supplied in Tape & Reel (TR), while SMBJ6.5A-E3/52 is supplied in Cut Tape (CT) & Digi-Reel®. Electrical performance is identical.

Q: What is the difference between SMBJ6.5A from Taiwan Semiconductor and the Vishay part? A: The Taiwan Semiconductor SMBJ6.5A maintains the same voltage specifications (6.5V reverse standoff, 11.2V clamping) but specifies 56A peak pulse current versus 53.6A for the Vishay part. Both are rated for 600W peak pulse power and operate across -55°C to 150°C. The higher current rating provides additional margin.

Q: Is SM6T7V5A a suitable substitute? A: SM6T7V5A differs in electrical performance: 6.4V reverse standoff (vs. 6.5V), 14.5V clamping (vs. 11.2V), and 276A peak pulse current (vs. 53.6A). This part operates at higher clamping voltage and significantly higher current capacity. Substitution requires circuit-level analysis to confirm compatibility with the intended application.

Q: Do all substitute parts have the same package footprint? A: Yes. All listed substitute parts use DO-214AA (SMB) package with identical mechanical dimensions and surface mount compatibility. PCB layout and reflow profiles remain unchanged.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed carry RoHS3 compliance certification and MSL 1 (unlimited) moisture sensitivity rating, meeting the same environmental and regulatory requirements as the primary part.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Both are surface mount packaging formats. Tape & Reel (TR) is supplied on continuous reel for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® is supplied in tape segments on a reel. Electrical specifications and component performance are identical; packaging choice depends on assembly equipment and volume requirements.
