SMF9.0A-TP Equivalent & Substitute Parts

Part Overview

The SMF9.0A-TP is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 9V reverse standoff voltage with a 15.4V maximum clamping voltage and 13A peak pulse current capability in a compact SOD-123FL package. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Equivalent and substitute parts are identified to provide procurement flexibility and supply chain alternatives while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF9.0A-TP are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is equivalence across all critical electrical specifications: reverse standoff voltage (9V), breakdown voltage (10V minimum), clamping voltage (15.4V maximum at Ipp), and peak pulse current (13A). Mechanical compatibility is ensured through identical package designation (SOD-123F) and surface-mount mounting type. All substitute parts must maintain the same unidirectional Zener diode topology with single channel configuration. Compliance certifications, including ROHS3 and REACH status, must be equivalent or superior. Operating temperature range variations are acceptable provided the substitute part covers the application's required operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the SMF9.0A-TP and SMF9.0A meet identical electrical specifications for transient voltage suppression applications. Selection between these parts is based on supply availability, lead time, and procurement cost. The SMF9.0A-TP offers an extended operating temperature range (-65°C to 175°C) compared to the SMF9.0A (-55°C to 150°C), making it preferable for applications requiring operation at temperature extremes. Both parts maintain active production status and full ROHS3 and REACH compliance, ensuring long-term availability and regulatory conformance. The SMF9.0A provides significantly higher inventory availability (35,100 pieces) relative to the SMF9.0A-TP (2,240 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can SMF9.0A be used as a direct replacement for SMF9.0A-TP?

A: Yes. Both parts share identical electrical specifications including 9V reverse standoff voltage, 15.4V clamping voltage, and 13A peak pulse current. Both use SOD-123F packaging and surface-mount technology. The primary difference is operating temperature range; verify your application's temperature requirements before substitution.

Q: What is the difference between SOD-123FL and SMF/SOD-123FL package designations?

A: Both designations refer to the same physical SOD-123F package form factor. The supplier device package notation reflects manufacturer-specific naming conventions. Mechanical and electrical compatibility is identical.

Q: Are there any compliance differences between these parts?

A: No. Both SMF9.0A-TP and SMF9.0A are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for modern electronics manufacturing.

Q: Which part should I select for high-temperature applications?

A: The SMF9.0A-TP supports operation up to 175°C (TA), compared to 150°C (TJ) for the SMF9.0A. For applications requiring extended high-temperature performance, the SMF9.0A-TP is the appropriate selection.

Q: Is packaging format (Tape & Reel) identical between these parts?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
