TV02W110-G Equivalent & Substitute Parts

Part Overview

The TV02W110-G is an 11V Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose transient protection applications. This unidirectional Zener-type TVS diode features an 18.2V maximum clamping voltage and 10.99A peak pulse current capability in a surface-mount SOD-123 package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TV02W110-G are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 11V
• Voltage - Breakdown (Min): 12.2V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Current - Peak Pulse: Equal to or greater than 10.99A
• Power - Peak Pulse: Equal to or greater than 200W
• Package / Case: SOD-123 family variants (SOD-123, SOD-123W, SOD-123F/SMF)
• Operating Temperature Range: Equal to or greater than -55°C to 150°C minimum

All identified substitutes maintain identical voltage specifications while offering equal or enhanced current and power handling capabilities. Package variants within the SOD-123 family are mechanically compatible for surface-mount applications.

Parameter Comparison

Engineering Selection Recommendations

PTVS11VS1UR,115 (Nexperia USA Inc.): This substitute offers doubled peak pulse current (22A) and power dissipation (400W) compared to the TV02W110-G, with identical voltage specifications. The part carries automotive-grade qualification (AEC-Q101) and maintains the -55°C to 150°C operating range. The SOD-123W package is mechanically compatible with standard SOD-123 footprints in most applications. This option is suitable for designs requiring enhanced transient protection margin or automotive-grade reliability.

PTVS11VS1UTR,115 (Nexperia USA Inc.): This variant provides the same electrical enhancements as PTVS11VS1UR,115 with an extended operating temperature range to 185°C (TA). Automotive-grade qualification (AEC-Q101) and doubled current/power ratings apply. Selection of this part is appropriate for high-temperature environments or applications requiring extended thermal performance beyond standard specifications.

SMF11A (MDD): This substitute maintains the original 200W power dissipation and 11A peak pulse current, providing near-identical electrical performance to the TV02W110-G. The SMF/SOD-123FL package variant is mechanically compatible with standard SOD-123 footprints. This option is suitable for direct replacement in applications where current and power ratings are not limiting factors and package footprint compatibility is the primary consideration.

Frequently Asked Questions (FAQ)

Q: Can PTVS11VS1UR,115 or PTVS11VS1UTR,115 be used as direct replacements for TV02W110-G?

A: Yes. Both Nexperia parts maintain identical voltage specifications (11V standoff, 12.2V breakdown, 18.2V clamping) and unidirectional Zener topology. The SOD-123W package is mechanically compatible with SOD-123 footprints. The doubled current and power ratings provide enhanced protection margin without compromising circuit performance.

Q: What is the difference between PTVS11VS1UR,115 and PTVS11VS1UTR,115?

A: Both parts are electrically identical with 22A peak pulse current and 400W power dissipation. The primary difference is operating temperature range: PTVS11VS1UR,115 operates to 150°C (TA), while PTVS11VS1UTR,115 extends to 185°C (TA). Selection depends on thermal environment requirements.

Q: Is SMF11A a suitable substitute for TV02W110-G?

A: Yes. SMF11A provides equivalent electrical performance with 11A peak pulse current and 200W power dissipation, matching the original part's ratings. The SMF/SOD-123FL package is mechanically compatible with standard SOD-123 footprints. This substitute is appropriate when current and power handling are not limiting design factors.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TV02W110-G and all identified substitutes (PTVS11VS1UR,115, PTVS11VS1UTR,115, SMF11A) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Do the Nexperia substitutes require design re-qualification?

A: The Nexperia parts carry automotive-grade qualification (AEC-Q101), which may require evaluation based on your application's qualification requirements. Electrical compatibility is confirmed through identical voltage specifications and enhanced current/power ratings. Mechanical compatibility is confirmed through SOD-123 family package compatibility.

Q: What are the inventory considerations for these substitutes?

A: TV02W110-G has 910 pcs in stock. PTVS11VS1UR,115 has 18,860 pcs available. PTVS11VS1UTR,115 has 2,054 pcs available. SMF11A has 17,300 pcs available. Substitute selection may be influenced by inventory availability and lead time requirements.
