SMBJ7.0A-M3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ7.0A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 7V reverse standoff category with a 12V maximum clamping voltage and 50A peak pulse current rating. The device is designed for general-purpose transient voltage suppression applications and maintains Active product status. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the DO-214AA (SMB) package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ7.0A-M3/5B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 50A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical electrical performance specifications and package compatibility. Variations in operating temperature range and manufacturer do not affect functional substitution within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection among equivalent options may be based on inventory availability and operating temperature requirements. The SMBJ7.0A-TP variant supports an extended upper operating temperature of 175°C compared to the standard 150°C maximum. The SMBJ7.0A variant from MDD supports a minimum operating temperature of -50°C versus -55°C for other options. All parts are certified for unlimited moisture sensitivity handling (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.0A-E3/52 be used as a direct replacement for SMBJ7.0A-M3/5B?

A: Yes. Both parts share identical electrical specifications (7V reverse standoff, 7.78V breakdown minimum, 12V clamping maximum, 50A peak pulse current, 600W peak power) and are packaged in DO-214AA (SMB) surface mount configuration. Both are manufactured by Vishay and maintain ROHS3 compliance.

Q: What is the difference between SMBJ7.0A-TP and SMBJ7.0A-M3/5B?

A: The primary difference is the maximum operating temperature. SMBJ7.0A-TP supports -55°C to 175°C, while SMBJ7.0A-M3/5B supports -55°C to 150°C. All electrical parameters and package specifications are identical. Selection depends on application temperature requirements.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed parts use the DO-214AA (SMB) package and surface mount configuration, ensuring mechanical and footprint compatibility across all substitutes.

Q: Does manufacturer selection affect performance?

A: No. All substitute parts meet identical electrical specifications for voltage, current, and power ratings. Manufacturer differences do not impact functional performance within the specified parameter set.

Q: What is the significance of the part number suffixes (M3/5B, E3/52, 13-F, TP)?

A: These suffixes denote packaging variants, tape specifications, or manufacturer-specific designations. They do not alter the core electrical characteristics or functional performance of the TVS diode.
