SMBJ110CA-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ110CA-M3/52 is a bidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface mount component in DO-214AA (SMB) package is designed for general purpose transient voltage suppression applications. The part is Active status and widely used in circuit protection designs requiring 110V reverse standoff voltage with 177V maximum clamping voltage. Substitute parts are necessary to address inventory availability, packaging format requirements, or manufacturer sourcing preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ110CA-M3/52 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Clamping (Max) @ Ipp: 177V (±3V tolerance acceptable)
• Current - Peak Pulse (10/1000µs): 3.4A (±0.05A tolerance acceptable)
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Acceptable Variations:

• Voltage - Breakdown (Min): 122V–124V range
• Packaging format: Tape & Reel (TR) or Bulk
• Manufacturer: Vishay General Semiconductor - Diodes Division or Fairchild Semiconductor
• Series designation: TransZorb® or SMBJ

Parts meeting these criteria maintain functional equivalence for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

SMBJ110CA-E3/52 (Vishay - Manufacturer Recommended) This part is designated as the manufacturer-recommended substitute. It maintains identical electrical specifications to the main part (177V clamping, 3.4A peak pulse) with Tape & Reel packaging. ROHS3 compliance and MSL 1 rating match the original specification. Selection is appropriate for applications requiring manufacturer-validated equivalence.

SMBJ110CD-M3/H (Vishay - Direct Substitute) This part provides functional equivalence with minor clamping voltage variation (174V vs. 177V, within 1.7% tolerance) and slightly higher peak pulse current (3.45A vs. 3.4A). Breakdown voltage is 124V (vs. 122V minimum). ROHS3 compliance and MSL 1 rating are maintained. Tape & Reel packaging is provided. Selection is appropriate where inventory availability is prioritized.

SMBJ110CA (Fairchild - Bulk Packaging) This part matches electrical specifications (177V clamping, 3.4A peak pulse, 122V breakdown) but is supplied in Bulk packaging rather than Tape & Reel. RoHS and MSL compliance status are not specified. Selection is appropriate for applications where bulk packaging is acceptable and cost optimization is prioritized.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110CD-M3/H be used as a direct replacement for SMBJ110CA-M3/52? A: Yes. Both parts maintain 110V reverse standoff voltage, 600W peak pulse power, and identical operating temperature range. The clamping voltage difference (174V vs. 177V) represents a 1.7% variation within acceptable tolerance for general purpose transient suppression. Peak pulse current is slightly higher (3.45A vs. 3.4A), providing equivalent or improved performance.

Q: What is the difference between Tape & Reel and Bulk packaging? A: Tape & Reel (TR) packaging is used for automated assembly processes and provides components on continuous carrier tape. Bulk packaging supplies loose components. Selection depends on manufacturing process requirements. The SMBJ110CA from Fairchild uses Bulk packaging, while Vishay variants use Tape & Reel.

Q: Are all substitute parts ROHS3 compliant? A: The Vishay parts (SMBJ110CA-M3/52, SMBJ110CD-M3/H, SMBJ110CA-E3/52) are explicitly ROHS3 compliant. The Fairchild SMBJ110CA does not specify RoHS compliance status in the provided data.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. This applies to all Vishay variants provided.

Q: Can I substitute based on voltage ratings alone? A: No. Substitution requires matching multiple parameters: reverse standoff voltage (110V), clamping voltage (177V ±3V), peak pulse current (3.4A ±0.05A), power rating (600W), package type (DO-214AA, SMB), and operating temperature range (-55°C ~ 150°C). All substitute parts listed meet these combined criteria.

Q: Which substitute should I select for new designs? A: SMBJ110CA-E3/52 is the manufacturer-recommended substitute and provides identical electrical specifications with confirmed ROHS3 compliance and MSL 1 rating. This part is appropriate for new designs requiring validated manufacturer equivalence.
