SMF5.0A-T13 Equivalent & Substitute Parts

Part Overview

The SMF5.0A-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 operates with a 5V reverse standoff voltage and provides 9.2V clamping at peak pulse current, delivering 200W peak pulse power dissipation in a compact SOD-123F package. The part is active in production and ROHS3 compliant, making it suitable for modern electronic designs requiring transient suppression without power line protection requirements.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required for assembly processes, or when sourcing from different distributors is needed to optimize supply chain logistics while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMF5.0A-T13 is determined by strict equivalence across the following critical electrical parameters: reverse standoff voltage (5V), breakdown voltage minimum (6.4V), clamping voltage maximum at peak pulse current (9.2V), peak pulse current rating (21.7A), and peak pulse power dissipation (200W). All substitute parts must maintain these exact electrical specifications to ensure functional interchangeability in the circuit.

Mechanical compatibility requires surface-mount mounting type and SOD-123F package classification. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) may vary between substitutes without affecting electrical performance, though assembly process compatibility should be verified with manufacturing specifications.

Compliance requirements include ROHS3 certification and MSL Level 1 rating. Operating temperature range may extend beyond the original specification without compromising substitution validity, provided the minimum range encompasses the original -55°C to 150°C (TJ) specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SMF5.0A-T13, SMF5.0A, and SMF5.0A-TP—are electrically equivalent and meet identical functional requirements for transient voltage suppression applications. Selection between these parts should be based on the following criteria:

Packaging Format Compatibility: The SMF5.0A-T13 and SMF5.0A-TP are supplied in Tape & Reel format, suitable for automated pick-and-place assembly. The SMF5.0A is available in Cut Tape and Digi-Reel formats, which may require different feeder configurations on assembly equipment.

Compliance and Certification: All three parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and storage requirements.

Temperature Operating Range: The SMF5.0A-TP offers an extended operating temperature range (-65°C to 175°C TA) compared to the original specification (-55°C to 150°C TJ), providing additional thermal margin for applications operating at temperature extremes.

Availability and Supply Chain: Part selection should prioritize current inventory levels and lead times from qualified distributors to optimize procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can SMF5.0A-TP be used as a direct replacement for SMF5.0A-T13?

A: Yes. Both parts maintain identical electrical specifications: 5V reverse standoff voltage, 6.4V minimum breakdown voltage, 9.2V clamping voltage at peak pulse current, 21.7A peak pulse current, and 200W peak pulse power dissipation. Both are surface-mount components in SOD-123F packages with ROHS3 compliance and MSL Level 1 rating.

Q: What is the difference between the packaging formats offered?

A: SMF5.0A-T13 and SMF5.0A-TP are supplied in Tape & Reel (TR) format for automated assembly. SMF5.0A is available in Cut Tape (CT) and Digi-Reel formats. Tape & Reel format is standard for high-volume pick-and-place assembly, while Cut Tape is used for lower-volume or manual assembly processes. Digi-Reel is a proprietary format optimized for specific feeder systems.

Q: Does the extended temperature range of SMF5.0A-TP affect circuit performance?

A: No. The extended operating temperature range (-65°C to 175°C TA) of SMF5.0A-TP does not alter electrical performance within the standard operating range. It provides additional thermal margin for applications exposed to extreme environmental conditions.

Q: Are all three parts ROHS3 compliant?

A: Yes. SMF5.0A-T13, SMF5.0A, and SMF5.0A-TP are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting modern environmental and manufacturing standards.

Q: What determines whether a part can substitute for SMF5.0A-T13?

A: Substitution is determined by electrical equivalence across reverse standoff voltage (5V), breakdown voltage (6.4V minimum), clamping voltage (9.2V maximum at peak pulse), peak pulse current (21.7A), and peak pulse power (200W). Mechanical compatibility requires surface-mount mounting and SOD-123F package classification. Compliance certifications must include ROHS3 and MSL Level 1.
