SMF10A-TP Equivalent & Substitute Parts

Part Overview

The SMF10A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This surface-mount component operates with a 10V reverse standoff voltage and provides 200W peak pulse power dissipation in a compact SOD-123FL package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF10A-TP are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V minimum
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): ≥11.76A
• Power - Peak Pulse: 200W
• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• Product Status: Active
• RoHS3 Compliance: Required

The SMF10A manufactured by Diotec Semiconductor meets all specified electrical parameters and maintains identical package and mounting characteristics, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SMF10A-TP (Micro Commercial Co) and SMF10A (Diotec Semiconductor) are active production components with full RoHS3 compliance. The electrical parameters are equivalent across all critical specifications: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation. Both components utilize identical SOD-123F surface-mount packaging, ensuring mechanical and thermal compatibility in PCB layouts.

The Diotec Semiconductor SMF10A variant operates within a narrower junction temperature range (-50°C to 150°C) compared to the Micro Commercial Co version (-65°C to 175°C). Design applications requiring operation at the temperature extremes should verify that the Diotec part's operating range satisfies system requirements.

Selection between these parts should be based on procurement availability, supply chain logistics, and specific temperature operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the Diotec Semiconductor SMF10A directly replace the Micro Commercial Co SMF10A-TP in existing designs?

A: Yes. Both parts share identical electrical specifications for reverse standoff voltage (10V), breakdown voltage (11.1V minimum), clamping voltage (17V), peak pulse current (11.76-11.8A), and power dissipation (200W). The SOD-123F package and surface-mount configuration are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the different operating temperature ranges?

A: The Micro Commercial Co SMF10A-TP operates from -65°C to 175°C (TA), while the Diotec Semiconductor SMF10A operates from -50°C to 150°C (TJ). Applications requiring operation below -50°C or above 150°C must use the Micro Commercial Co variant. For standard industrial and commercial temperature ranges, both parts are functionally equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SMF10A-TP and SMF10A are RoHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Does packaging differ between these parts?

A: No. Both components are supplied in SOD-123F surface-mount packages. The Micro Commercial Co part is available in Tape & Reel (TR) packaging, while the Diotec part is supplied in SOD-123F (SMF) format. Both are compatible with standard pick-and-place assembly equipment and PCB footprints.

Q: What is the peak pulse current specification, and why is it important?

A: The peak pulse current (10/1000µs) is 11.8A for the Micro Commercial Co part and 11.76A for the Diotec part. This specification defines the maximum transient current the TVS diode can safely suppress during a 10µs pulse with 1000µs recovery time. Both values are equivalent for practical circuit protection applications.
