SMBJ110C-E3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ110C-E3/5B is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 110V reverse standoff voltage and provides 196V maximum clamping voltage at peak pulse current. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ110C-E3/5B is determined by the following critical parameters:

• Voltage - Reverse Standoff: 110V (must match)
• Voltage - Breakdown (Min): 122V (must match)
• Package / Case: DO-214AA, SMB (must match for mechanical compatibility)
• Mounting Type: Surface Mount (must match)
• Bidirectional Channels: 1 (must match)
• Type: Zener (must match)

Substitute parts may vary in:

• Voltage - Clamping (Max) @ Ipp: within acceptable range for the application
• Current - Peak Pulse (10/1000µs): equal or greater capacity
• Manufacturer and product status (active alternatives preferred over obsolete)
• Packaging format (Bulk vs. Tape & Reel)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the SMBJ110C-E3/5B. Selection should prioritize active product status and compliance certifications:

SMBJ110CA-E3/5B (Vishay) is the direct Vishay equivalent with active product status and ROHS3 compliance. This part maintains the same manufacturer lineage and is available in Tape & Reel packaging.

SMBJ110CA (Fairchild) offers the highest inventory availability (44,300 pcs) and active status. This part is supplied in Bulk packaging and is suitable for high-volume applications.

SMBJ110CAE3/TR13 (Microchip) provides extended operating temperature range (-65°C to 150°C) compared to the main part (-55°C to 150°C), with ROHS3 compliance and Tape & Reel packaging.

TV06B111JB-HF (Comchip) is an alternative source with active status, ROHS3 compliance, and Tape & Reel packaging. Peak pulse current is 3.39A, functionally equivalent to other substitutes.

All substitute parts feature lower clamping voltage (177V vs. 196V) and higher peak pulse current (3.34-3.4A vs. 3.1A), representing improved performance characteristics within the same voltage class.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110CA-E3/5B directly replace SMBJ110C-E3/5B?

A: Yes. Both parts share identical reverse standoff voltage (110V), breakdown voltage (122V), and package specifications (DO-214AA, SMB). The clamping voltage difference (177V vs. 196V) and increased peak pulse current (3.4A vs. 3.1A) represent improved suppression characteristics. SMBJ110CA-E3/5B is the active equivalent from Vishay.

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

A: Bulk packaging is suitable for manual assembly or small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly and high-volume production. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: SMBJ110CA-E3/5B, SMBJ110CAE3/TR13, and TV06B111JB-HF are confirmed ROHS3 compliant. SMBJ110CA (Fairchild) compliance status is not specified in available documentation.

Q: Does the lower clamping voltage of substitute parts affect circuit protection?

A: No. Lower clamping voltage (177V vs. 196V) provides superior transient suppression by limiting voltage rise to a lower threshold. This represents an improvement over the original part for overvoltage protection applications.

Q: Which substitute part has the widest operating temperature range?

A: SMBJ110CAE3/TR13 (Microchip) operates from -65°C to 150°C, extending the lower temperature limit by 10°C compared to the main part and SMBJ110CA-E3/5B (-55°C to 150°C).

Q: Can I use these parts interchangeably in existing designs?

A: Yes. All substitute parts are mechanically and electrically compatible with the SMBJ110C-E3/5B in DO-214AA, SMB package format. No circuit modifications are required for substitution.
