SMBJ110CA Equivalent & Substitute Parts

Part Overview

The SMBJ110CA is an active-status transient voltage suppressor (TVS) diode designed for general-purpose overvoltage protection applications. This surface-mount component operates across a temperature range of -55°C to 150°C and is housed in a DO-214AA (SMB) package. The part is manufactured by Taiwan Semiconductor Corporation and is RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility, enabling component selection flexibility across multiple manufacturers while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ110CA is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 3.4A
• Power - Peak Pulse: 600W

Mechanical Equivalence Criteria:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Compliance Equivalence Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts match these parameters across all three equivalence categories. Packaging format (Tape & Reel versus Bulk) does not affect electrical or mechanical compatibility and represents a supply-chain variable only.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed in this reference are active-status components suitable for direct substitution in applications requiring 110V reverse standoff TVS protection with 3.4A peak pulse current handling.

Compliance Considerations:

The SMBJ110CA from Taiwan Semiconductor Corporation, SMBJ110CA-13-F from Diodes Incorporated, and SMBJ110CA-E3/52 from Vishay all carry explicit RoHS3 compliance certification and REACH Unaffected status with MSL 1 (Unlimited) moisture sensitivity rating. These three parts are fully equivalent for applications with regulatory compliance requirements.

The SMBJ110CA from Fairchild Semiconductor matches all electrical and mechanical parameters but does not include explicit compliance documentation in the provided specifications. Selection of this variant should be based on supply availability and cost considerations when compliance documentation is not a circuit requirement.

Packaging Format:

Taiwan Semiconductor Corporation and Diodes Incorporated supply their variants in Tape & Reel (TR) format, suitable for automated assembly processes. Fairchild Semiconductor supplies in Bulk format, appropriate for manual assembly or alternative handling methods. This distinction affects procurement and assembly workflow but does not impact electrical performance.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110CA-E3/52 from Vishay be used as a direct replacement for SMBJ110CA from Taiwan Semiconductor Corporation?

A: Yes. Both parts share identical electrical specifications (110V reverse standoff, 122V minimum breakdown, 177V maximum clamping voltage, 3.4A peak pulse current, 600W peak pulse power), identical mechanical packaging (DO-214AA SMB surface mount), and equivalent compliance certifications (RoHS3, REACH Unaffected, MSL 1). The part number suffix "-E3/52" indicates Vishay's internal coding and does not affect compatibility.

Q: What is the difference between Tape & Reel and Bulk packaging for the SMBJ110CA?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Bulk packaging supplies loose components. Both formats contain electrically and mechanically identical parts. Packaging selection depends on assembly process requirements and does not affect circuit performance.

Q: Are all substitute parts rated for the same temperature range?

A: Yes. All four parts operate across the identical temperature range of -55°C to 150°C (junction temperature). Temperature performance is equivalent across all variants.

Q: Does the SMBJ110CA-13-F designation from Diodes Incorporated indicate a different electrical specification?

A: No. The "-13-F" suffix is a Diodes Incorporated internal part number designation. The electrical specifications (110V reverse standoff, 122V breakdown, 177V clamping, 3.4A peak pulse current, 600W peak power) are identical to the base SMBJ110CA specification. This part is a direct electrical equivalent.

Q: Which substitute part should be selected for applications requiring RoHS3 compliance?

A: SMBJ110CA-13-F from Diodes Incorporated, SMBJ110CA-E3/52 from Vishay General Semiconductor, and SMBJ110CA from Taiwan Semiconductor Corporation all carry explicit RoHS3 compliance certification. Any of these three parts meets RoHS3 requirements. The Fairchild Semiconductor variant does not include explicit compliance documentation.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. All parts use the DO-214AA (SMB) surface-mount package with identical pin configuration and footprint. PCB layout and reflow soldering parameters remain unchanged across all variants.
