SMF6.0A-TP Equivalent & Substitute Parts

Part Overview

The SMF6.0A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient protection applications. This surface-mount component operates with a 6V reverse standoff voltage and provides peak pulse current handling of 19.4A with a maximum clamping voltage of 10.3V. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic designs requiring transient voltage suppression in compact form factors.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate regional availability variations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF6.0A-TP are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 6V
• Voltage - Clamping (Max) @ Ipp: 10.3V
• Current - Peak Pulse (10/1000µs): 19.4A (±0.02A tolerance acceptable)
• Power - Peak Pulse: 200W
• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)

Two substitute parts meet these electrical and mechanical criteria: SMF6.0A (Diotec Semiconductor) and SZSMF6.0AT1G (Littelfuse Inc.). Both maintain identical voltage ratings, clamping characteristics, and power dissipation specifications. Package compatibility is confirmed through SOD-123F form factor equivalence. Differences in operating temperature ranges and certifications do not affect core transient suppression functionality.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance, confirming suitability for current design requirements. The SMF6.0A-TP and SZSMF6.0AT1G share identical electrical specifications and operating temperature ranges, providing direct functional equivalence. The SMF6.0A (Diotec) operates within a narrower temperature range (-50°C to 150°C) compared to the primary part (-65°C to 175°C), which may require thermal analysis for applications at temperature extremes.

The SZSMF6.0AT1G carries AEC-Q101 automotive qualification, making it the preferred choice for automotive and high-reliability applications. Selection between SMF6.0A and SZSMF6.0AT1G should be based on application requirements and regional supply availability, as both provide equivalent electrical performance for general-purpose transient suppression.

Frequently Asked Questions (FAQ)

Q: Can SMF6.0A (Diotec) be used as a direct replacement for SMF6.0A-TP in all applications?

A: SMF6.0A provides equivalent electrical performance across all critical parameters. However, its operating temperature range (-50°C to 150°C) is narrower than the original part (-65°C to 175°C). Verify application temperature requirements before substitution.

Q: What is the difference between SMF6.0A-TP and SZSMF6.0AT1G?

A: Both parts share identical electrical specifications (6V standoff, 10.3V clamping, 19.4A peak pulse, 200W power). The primary difference is that SZSMF6.0AT1G includes AEC-Q101 automotive qualification and operates across -55°C to 150°C. Choose SZSMF6.0AT1G for automotive applications.

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

A: Yes. All three parts use the SOD-123F package with identical pin configuration and land pattern requirements for surface-mount assembly.

Q: Do substitute parts maintain the same moisture sensitivity level?

A: SMF6.0A-TP and SZSMF6.0AT1G both specify MSL 1 (Unlimited). SMF6.0A (Diotec) lists MSL as Not Applicable. Consult component datasheets for specific moisture handling requirements during storage and assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: SMF6.0A-TP supports operation to 175°C, while SMF6.0A and SZSMF6.0AT1G are rated to 150°C. For applications exceeding 150°C, use SMF6.0A-TP or verify thermal performance with substitute datasheets.
