SMF8.0A-T13 Equivalent & Substitute Parts

Part Overview

The SMF8.0A-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 an 8V reverse standoff voltage and provides 13.6V maximum clamping voltage at peak pulse current. The part is Active in product status and widely used in circuit protection where transient voltage events require rapid suppression.

Substitute parts become necessary due to inventory availability, supply chain constraints, or procurement preferences while maintaining equivalent electrical and mechanical performance within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMF8.0A-T13 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 8V (typical)
• Voltage - Breakdown: 8.89V (minimum)
• Voltage - Clamping: 13.6V (maximum at Ipp)
• Current - Peak Pulse: 14.7A (10/1000µs)
• Power - Peak Pulse: 200W
• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)

The substitute part SMF8.0A-TP, manufactured by Micro Commercial Co, meets all electrical specifications and mechanical requirements. Both parts share the same base product number (SMF8.0) and are classified as Active products with equivalent RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both the SMF8.0A-T13 and SMF8.0A-TP are suitable for direct substitution based on electrical and mechanical equivalence. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Procurement source preferences
• Operating temperature range requirements (SMF8.0A-T13: -55°C to 150°C TJ; SMF8.0A-TP: -65°C to 175°C TA)
• Compliance certifications (both are ROHS3 Compliant and REACH Unaffected)
• Packaging format (both use Tape & Reel)

Both parts maintain Active product status and are suitable for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SMF8.0A-TP replace SMF8.0A-T13 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 8V reverse standoff voltage, 13.6V clamping voltage, 14.7A peak pulse current, and 200W peak pulse power. Both use SOD-123F surface-mount packaging.

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

A: The primary differences are manufacturer (Littelfuse vs. Micro Commercial Co) and operating temperature range. SMF8.0A-T13 operates from -55°C to 150°C (junction temperature), while SMF8.0A-TP operates from -65°C to 175°C (ambient temperature). Both meet ROHS3 and REACH compliance requirements.

Q: Are there any package compatibility concerns?

A: No. Both parts use identical SOD-123F surface-mount packaging and are supplied in Tape & Reel format, ensuring compatibility with standard pick-and-place assembly equipment.

Q: What electrical parameters determine substitution eligibility?

A: Substitution is based on matching voltage ratings (8V standoff, 8.89V breakdown minimum, 13.6V clamping maximum), peak pulse current (14.7A), and peak pulse power (200W). Both parts meet these specifications identically.

Q: Are both parts currently available?

A: Both parts maintain Active product status. SMF8.0A-T13 has 713 pieces in stock, while SMF8.0A-TP has 2262 pieces in stock, providing flexibility for procurement decisions.
