Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ22CA-M3/5B are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 22V
• Voltage - Clamping (Max) @ Ipp: 35.5V or equivalent (35.1V acceptable within tolerance)
• Current - Peak Pulse (10/1000µs): 16.9A or higher
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Compliance Requirements:

• RoHS3 Compliant
• MSL: 1 (Unlimited)
• Product Status: Active

Substitute parts meeting these criteria are electrically and mechanically interchangeable with the main part number in general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the SMBJ22CA-M3/5B in general-purpose transient voltage suppression applications. Selection among substitutes should be based on:

Compliance & Certification: All substitute parts are RoHS3 compliant and carry MSL 1 (Unlimited) rating, matching the main part's compliance profile.

Product Status: All parts maintain Active status, ensuring ongoing manufacturer support and availability.

Temperature Range Considerations: The SMBJ22CA-TP variant extends the upper operating temperature to 175°C, compared to 150°C for the main part and most substitutes. The 1SMB22CA TR13 PBFREE extends the lower temperature to -65°C. The MDD SMBJ22CA variant operates from -50°C. Selection should align with application temperature requirements.

Peak Pulse Current: The SMBJ22CD-M3/I and SMBJ22CA-TR variants provide slightly higher peak pulse current (17.1A and 17.7A respectively) compared to the main part's 16.9A, offering enhanced transient suppression capability within the same voltage and power specifications.

Clamping Voltage: The SMBJ22CD-M3/I variant specifies 35.1V clamping voltage, marginally lower than the main part's 35.5V, remaining within acceptable tolerance for the 22V reverse standoff category.

Frequently Asked Questions (FAQ)

Q: Can SMBJ22CD-M3/I be used as a direct replacement for SMBJ22CA-M3/5B?

A: Yes. Both parts share identical reverse standoff voltage (22V), power rating (600W), package (DO-214AA, SMB), and operating temperature range (-55°C ~ 150°C). The SMBJ22CD-M3/I provides marginally higher peak pulse current (17.1A vs. 16.9A) and slightly lower clamping voltage (35.1V vs. 35.5V), both within acceptable tolerance for the 22V category.

Q: What is the difference between SMBJ22CA-E3/5B and SMBJ22CA-M3/5B?

A: Both parts are manufactured by Vishay and share identical electrical specifications: 22V reverse standoff, 35.5V clamping voltage, 16.9A peak pulse current, and 600W power rating. The primary difference is packaging format: SMBJ22CA-E3/5B is supplied in Cut Tape (CT) & Digi-Reel®, while SMBJ22CA-M3/5B is supplied in Tape & Reel (TR). Electrical performance and compatibility are equivalent.

Q: Are all substitute parts in the same DO-214AA SMB package?

A: Yes. All listed substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility with the main part.

Q: Which substitute offers the widest operating temperature range?

A: The SMBJ22CA-TP variant extends the upper operating temperature to 175°C, compared to 150°C for the main part. The 1SMB22CA TR13 PBFREE extends the lower temperature to -65°C. Selection depends on application temperature requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL 1 (Unlimited) rating, matching the main part's compliance profile.

Q: Can I use SMBJ22CA-TR from STMicroelectronics as a substitute?

A: Yes. The SMBJ22CA-TR meets all electrical and mechanical requirements. It provides 17.7A peak pulse current, slightly higher than the main part's 16.9A, while maintaining the same 22V reverse standoff, 35.5V clamping voltage, and 600W power rating.
