SMBG10A-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG10A-E3/52 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the TransZorb® series and is designed for general-purpose transient voltage suppression applications. The device features a 10V reverse standoff voltage with a 17V maximum clamping voltage and 35.3A peak pulse current capability. The part maintains active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified to address inventory availability, alternative sourcing requirements, or equivalent performance specifications across compatible package types.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG10A-E3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): ≥35.3A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C (TJ)
• Type: Zener, Unidirectional
• RoHS Status: ROHS3 Compliant

The SMBJ10A-TR qualifies as a manufacturer-recommended substitute because it maintains identical voltage specifications (10V standoff, 11.1V breakdown, 17V clamping), exceeds the peak pulse current requirement (37A vs. 35.3A), and preserves all thermal and compliance characteristics. Both devices operate within the same temperature range and meet ROHS3 compliance. The primary difference is the package variant (DO-215AA SMB Gull Wing vs. DO-214AA SMB) and supplier packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ10A-TR is qualified as a direct substitute for the SMBG10A-E3/52 based on electrical parameter equivalence and regulatory compliance alignment. Both devices maintain active product status and satisfy ROHS3 and REACH requirements. The SMBJ10A-TR demonstrates superior peak pulse current capability (37A vs. 35.3A), providing additional margin within the same thermal and power envelope. Package compatibility between DO-215AA and DO-214AA SMB variants is established through standard PCB footprint design practices for SMB surface mount devices. Selection between these parts should be based on availability, supplier lead time, and existing inventory management protocols rather than electrical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ10A-TR be used as a direct replacement for the SMBG10A-E3/52 on existing PCBs?

A: Yes. Both devices use compatible SMB surface mount packages (DO-215AA and DO-214AA variants). Standard SMB footprints accommodate both package geometries. Verify PCB layout against component datasheets to confirm pad dimensions and lead spacing compatibility.

Q: Are the voltage specifications identical between these two parts?

A: Yes. Both devices specify 10V reverse standoff voltage, 11.1V minimum breakdown voltage, and 17V maximum clamping voltage. They are electrically equivalent for transient voltage suppression applications within these parameters.

Q: What is the difference in peak pulse current between these parts?

A: The SMBJ10A-TR provides 37A peak pulse current compared to the SMBG10A-E3/52 at 35.3A. This represents a 1.7A increase, which remains within the same 600W power dissipation envelope and does not alter thermal performance characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG10A-E3/52 and SMBJ10A-TR are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: What is the primary reason to consider substitution?

A: Substitution is typically driven by inventory availability, supplier lead times, or sourcing optimization. The SMBJ10A-TR maintains equivalent electrical performance and compliance characteristics while potentially offering improved supply chain access through STMicroelectronics distribution channels.

Q: Are there any thermal performance differences?

A: No. Both devices operate across the identical temperature range (-55°C to 150°C junction temperature) and dissipate the same peak pulse power (600W). Thermal management requirements are equivalent.
