SMBG16A-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG16A-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 16V reverse standoff voltage with a 26V maximum clamping voltage and 23.1A peak pulse current capability. The part is currently active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent substitute parts are identified to provide design flexibility, alternative sourcing options, and inventory availability across different manufacturers and packaging formats.

Substitute Part Grouping Explanation

Substitute parts for the SMBG16A-E3/52 are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Voltage - Reverse Standoff: 16V (identical)
• Voltage - Clamping (Max) @ Ipp: 26V (identical)
• Current - Peak Pulse (10/1000µs): 23.1A (identical)
• Power - Peak Pulse: 600W (identical)
• Operating Temperature Range: -55°C to 150°C (identical)
• Unidirectional Channels: 1 (identical)
• Type: Zener (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 1 (Unlimited) (identical)

The SMBJ16A-TR manufactured by STMicroelectronics meets all critical electrical performance parameters. The primary difference is the package designation: the substitute uses DO-214AA (SMB) versus the original DO-215AA (SMB Gull Wing). Both packages are surface mount SMB form factors with compatible footprints for standard PCB assembly processes. The substitute is available in Cut Tape (CT) and Digi-Reel® packaging formats.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ16A-TR from STMicroelectronics is electrically and functionally equivalent to the SMBG16A-E3/52. Both devices maintain identical electrical performance across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation. Both parts are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity), meeting the same regulatory and environmental requirements.

The package difference between DO-215AA (SMB Gull Wing) and DO-214AA (SMB) represents a minor mechanical variation within the SMB form factor family. Both packages are surface mount compatible and suitable for standard PCB assembly processes. The substitute part is available in higher inventory quantity (1389 pcs versus 777 pcs) and offers alternative packaging formats (Cut Tape and Digi-Reel®) compared to the original Tape & Reel format.

Selection between these parts should be based on availability, packaging preference, and supply chain requirements rather than electrical performance, as all critical specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Are the SMBG16A-E3/52 and SMBJ16A-TR electrically interchangeable?

A: Yes. Both devices share identical electrical specifications including 16V reverse standoff voltage, 26V clamping voltage, 23.1A peak pulse current, and 600W peak pulse power. They are functionally equivalent for transient voltage suppression applications.

Q: What is the difference between DO-215AA and DO-214AA packages?

A: Both are surface mount SMB form factors. DO-215AA (SMB Gull Wing) and DO-214AA (SMB) are mechanically compatible variants within the SMB package family. The footprint and lead spacing are compatible for standard PCB assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG16A-E3/52 and SMBJ16A-TR are ROHS3 compliant with MSL rating 1 (unlimited). They meet identical regulatory and environmental requirements.

Q: What packaging formats are available for the substitute part?

A: The SMBJ16A-TR is available in Cut Tape (CT) and Digi-Reel® packaging formats, offering flexibility compared to the original Tape & Reel format.

Q: Can I use the SMBJ16A-TR as a direct replacement on existing PCBs designed for SMBG16A-E3/52?

A: Yes. The SMB package variants are mechanically compatible. PCB footprints designed for DO-215AA (SMB Gull Wing) accommodate DO-214AA (SMB) components without modification.

Q: Are there any temperature or operating condition differences?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) and are rated for the same general-purpose applications.
