SMF7.5A-T13 Equivalent & Substitute Parts

Part Overview

The SMF7.5A-T13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 7.5V reverse standoff voltage with a 12.9V maximum clamping voltage and 15.5A peak pulse current capability in a compact SOD-123F package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical parameters, mechanical packaging, and compliance certifications remain equivalent across manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the SMF7.5A-T13 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 7.5V (typical)
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 15.5A
• Power - Peak Pulse: 200W
• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• RoHS3 Compliance: Required
• Product Status: Active

The substitute part SMF7.5A-TP from Micro Commercial Co meets all electrical and mechanical requirements for direct substitution. Both parts share identical voltage ratings, peak pulse specifications, and packaging, enabling interchangeable use in circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

Both the SMF7.5A-T13 and SMF7.5A-TP are suitable for direct substitution based on electrical parameter equivalence and active product status. Selection between these parts should consider:

• Availability and lead time from respective manufacturers
• Supply chain continuity and inventory levels
• Operating temperature requirements: The SMF7.5A-TP supports an extended temperature range (-65°C to 175°C) compared to the SMF7.5A-T13 (-55°C to 150°C), making it preferable for applications requiring operation at temperature extremes
• RoHS3 and REACH compliance are maintained across both options
• Both parts carry ECCN EAR99 classification and identical HTSUS codes

Frequently Asked Questions (FAQ)

Q: Can SMF7.5A-TP replace SMF7.5A-T13 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical voltage ratings (7.5V standoff, 12.9V clamping), peak pulse current (15.5A), power dissipation (200W), and SOD-123F packaging. No circuit modifications are required.

Q: What are the key differences between these substitute parts?

A: The primary difference is operating temperature range. The SMF7.5A-TP operates from -65°C to 175°C, while the SMF7.5A-T13 operates from -55°C to 150°C. For applications within the SMF7.5A-T13 temperature range, both parts perform identically.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SMF7.5A-T13 and SMF7.5A-TP are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Does packaging differ between these parts?

A: No. Both parts use SOD-123F surface-mount packaging in tape and reel format, ensuring identical PCB footprint and assembly compatibility.

Q: Which part should be selected for high-temperature applications?

A: The SMF7.5A-TP is recommended for applications requiring operation above 150°C, as it supports temperatures up to 175°C. For applications within -55°C to 150°C, either part is suitable.
