SMF8.0A-TP Equivalent & Substitute Parts

Part Overview

The SMF8.0A-TP is an 8V unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient protection applications. This surface-mount component features a 13.6V maximum clamping voltage and 14.7A peak pulse current capability in a SOD-123FL package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF8.0A-TP are qualified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.8V to 8.89V range
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Current - Peak Pulse (10/1000µs): 14.7A minimum
• Power - Peak Pulse: 200W
• Type: Unidirectional Zener diode with single channel

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package compatibility: SOD-123F or equivalent footprint (SOD-123FL, DO-219AB)

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

SMF8.0A (Diotec Semiconductor): This direct equivalent shares identical electrical specifications with the main part. Both devices are active products with equivalent performance characteristics. The Diotec variant operates within a narrower temperature range (-50°C to 150°C) compared to the original part. RoHS compliance status differs; the Diotec part lists "Not applicable" while the original is ROHS3 compliant. Selection of this substitute should account for application temperature requirements and regulatory compliance needs.

SMF8V0A-E3-08 (Vishay): This substitute maintains all critical electrical parameters and extends the operating temperature range to match the original part (-65°C to 175°C). The Vishay device is packaged in DO-219AB (SMF) rather than SOD-123F, requiring PCB layout verification for footprint compatibility. Both the original and Vishay parts carry ROHS3 compliance and unlimited moisture sensitivity rating. This substitute is suitable for applications requiring extended temperature performance and equivalent regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can SMF8.0A from Diotec be used as a direct replacement for SMF8.0A-TP?

A: Yes, the Diotec SMF8.0A is electrically equivalent with matching voltage and current specifications. Verify that your application operates within the Diotec part's temperature range of -50°C to 150°C. Confirm RoHS compliance requirements for your end application.

Q: What is the difference between the SOD-123F and DO-219AB packages?

A: Both are surface-mount packages for TVS diodes with different physical footprints. SOD-123F and SOD-123FL are mechanically compatible. DO-219AB (SMF) has a different land pattern. PCB layout must be verified before substituting SMF8V0A-E3-08 (DO-219AB package) for the original SOD-123F package.

Q: Are all three parts RoHS compliant?

A: The SMF8.0A-TP and SMF8V0A-E3-08 are both ROHS3 compliant. The Diotec SMF8.0A lists RoHS status as "Not applicable." Confirm compliance requirements with your procurement and regulatory teams before selection.

Q: Which substitute should I choose for high-temperature applications?

A: Both the original SMF8.0A-TP and the Vishay SMF8V0A-E3-08 support the full -65°C to 175°C operating range. The Diotec SMF8.0A is limited to -50°C to 150°C and is not suitable for applications requiring the extended upper temperature limit.

Q: Can I use these parts interchangeably on the same PCB?

A: SMF8.0A-TP and Diotec SMF8.0A share the same SOD-123F footprint and are mechanically interchangeable. The Vishay SMF8V0A-E3-08 uses DO-219AB packaging and requires PCB layout verification before substitution.
