Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ11CA-TP are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 11V
• Voltage - Breakdown (Min): 12.2V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 33A
• Power - Peak Pulse: 600W
• Type: Zener
• Bidirectional Channels: 1

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the SMBJ11CA-TP in circuit applications requiring 11V TVS protection.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are electrically and mechanically equivalent to the SMBJ11CA-TP and are suitable for direct replacement in circuit designs. Selection among these alternatives should be based on the following factors:

Compliance & Certification: The SMBJ11CA-TP, SMBJ11CA-13-F, and SMBJ11CA-E3/52 are explicitly RoHS3 compliant with MSL rating of 1 (Unlimited). The Fairchild SMBJ11CA does not specify RoHS or MSL status in the provided data.

Operating Temperature Range: The SMBJ11CA-TP supports -55°C to 175°C, providing a 25°C advantage over substitute parts rated to -55°C to 150°C. Applications requiring operation above 150°C should prioritize the SMBJ11CA-TP.

Packaging Format: The SMBJ11CA-TP, SMBJ11CA-13-F, and SMBJ11CA-E3/52 are supplied in Tape & Reel format suitable for automated assembly. The Fairchild SMBJ11CA is supplied in Bulk packaging.

Inventory Availability: The Fairchild SMBJ11CA offers the highest stock level at 68980 units, followed by Vishay SMBJ11CA-E3/52 at 22650 units.

Frequently Asked Questions (FAQ)

Q: Can SMBJ11CA-TP be replaced with SMBJ11CA from Fairchild Semiconductor?

A: Yes. Both parts share identical electrical specifications (11V standoff, 12.2V breakdown, 18.2V clamping, 33A peak pulse, 600W peak power) and the same DO-214AA SMB package. However, the Fairchild part does not specify RoHS3 compliance or MSL rating in the provided documentation. If RoHS3 compliance is a design requirement, use SMBJ11CA-13-F or SMBJ11CA-E3/52 instead.

Q: What is the difference between SMBJ11CA-TP and SMBJ11CA-13-F?

A: Both parts are electrically identical with matching voltage and current ratings. The primary differences are manufacturer (Micro Commercial Co vs. Diodes Incorporated) and operating temperature range. SMBJ11CA-TP operates to 175°C while SMBJ11CA-13-F operates to 150°C. Both are RoHS3 compliant with MSL 1 rating.

Q: Is SMBJ11CA-E3/52 from Vishay a direct substitute?

A: Yes. The Vishay SMBJ11CA-E3/52 meets all electrical and mechanical requirements for substitution. It is RoHS3 compliant, MSL 1 rated, and packaged in DO-214AA SMB format. The part operates to 150°C, which is 25°C below the SMBJ11CA-TP maximum.

Q: Does packaging format affect substitutability?

A: Packaging format does not affect electrical or mechanical substitutability. The SMBJ11CA-TP, SMBJ11CA-13-F, and SMBJ11CA-E3/52 are supplied in Tape & Reel format for automated assembly. The Fairchild SMBJ11CA is supplied in Bulk. Both formats contain the same component in the same package; selection depends on assembly process requirements.

Q: Are all substitute parts currently in production?

A: Yes. All listed substitute parts have Active product status, indicating current manufacturing availability from their respective manufacturers.
