Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ14CD-M3/I and SMBJ14CA-E3/5B are Active status components manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent environmental handling and storage requirements.

The electrical parameters of the substitute part fall within acceptable tolerance ranges for TVS diode applications. The clamping voltage differential (22.9V vs. 23.2V) and peak pulse current variation (26.2A vs. 25.9A) are within typical manufacturing tolerances for this component category. Both parts share identical package specifications (DO-214AA, SMB) and mounting characteristics, ensuring direct mechanical compatibility on printed circuit boards.

Selection between these parts may be based on packaging format availability (Tape & Reel vs. Cut Tape & Digi-Reel®) and inventory considerations, as both meet the functional and compliance requirements for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ14CA-E3/5B be used as a direct replacement for SMBJ14CD-M3/I?

A: Yes. Both parts are manufactured by Vishay within the TransZorb® series, share identical reverse standoff voltage (14V), operate within the same temperature range (-55°C to 150°C), and use the same DO-214AA (SMB) surface mount package. Electrical parameters are within acceptable tolerance ranges for TVS diode applications.

Q: What is the difference in clamping voltage between these parts?

A: The SMBJ14CD-M3/I has a maximum clamping voltage of 22.9V at Ipp, while the SMBJ14CA-E3/5B is rated at 23.2V. This 0.3V difference is within typical manufacturing tolerances for TVS diodes and does not affect functional compatibility in general-purpose protection applications.

Q: Are there packaging differences between these parts?

A: The main part (SMBJ14CD-M3/I) is supplied in Tape & Reel (TR) format. The substitute (SMBJ14CA-E3/5B) is available in Cut Tape (CT) & Digi-Reel® format. Both use the same DO-214AA (SMB) component package, so mechanical compatibility on PCBs is identical. Packaging format selection depends on assembly process requirements and order quantity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBJ14CD-M3/I and SMBJ14CA-E3/5B are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified as Active status products.

Q: What is the peak pulse power rating for both parts?

A: Both parts are rated for 600W peak pulse power, ensuring equivalent transient energy dissipation capability in protection circuits.
