Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ9.0CA-M3/5B are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Breakdown (Min): 10V
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Current - Peak Pulse (10/1000µs): 39A or 40A
• Power - Peak Pulse: 600W
• Type: Zener, Bidirectional

Mechanical Parameters (Required for Compatibility):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Supplier Device Package: DO-214AA (SMBJ) or equivalent SMB variant

Compliance Parameters:

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

All substitute parts listed maintain these core specifications and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the SMBJ9.0CA-M3/5B. Selection among substitutes should be based on:

Availability: SMBJ9.0CA-13-F (Diodes Incorporated) offers the highest inventory at 98,300 pieces. SMBJ9.0CA-E3/52 (Vishay) provides 33,900 pieces with identical specifications to the main part.

Manufacturer Consistency: If maintaining the original Vishay manufacturer is preferred, SMBJ9.0CA-E3/52 and SMBJ9.0CA-E3/5B are direct equivalents with full specification alignment.

Temperature Range: SMBJ9.0CA-TP (Micro Commercial Co) extends the operating temperature range to -55°C to 175°C, providing additional thermal margin for high-temperature applications.

Peak Pulse Current: SMBJ9.0CA (Taiwan Semiconductor Corporation) specifies 40A peak pulse current compared to 39A in the main part, representing a 2.6% increase in transient handling capability while maintaining all other electrical parameters.

All substitute parts are Active status, RoHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compliance with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ9.0CA-E3/52 be used as a direct replacement for SMBJ9.0CA-M3/5B?

A: Yes. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications: 9V reverse standoff, 15.4V clamping voltage, 39A peak pulse current, and 600W peak pulse power. Both are packaged in DO-214AA (SMB) and operate across -55°C to 150°C. The difference in part number suffix reflects packaging or tape configuration variants, not electrical performance.

Q: What is the difference between SMBJ9.0CA (Taiwan Semiconductor Corporation) and the Vishay equivalent?

A: The Taiwan Semiconductor Corporation version specifies 40A peak pulse current versus 39A in the Vishay variant. This represents a 2.6% increase in transient current handling. All other electrical parameters, including voltage ratings, power dissipation, and operating temperature range, are identical. Both use the DO-214AA (SMB) package.

Q: Is SMBJ9.0CA-TP suitable for high-temperature environments?

A: SMBJ9.0CA-TP (Micro Commercial Co) extends the operating temperature range to -55°C to 175°C, compared to -55°C to 150°C for the main part. This 25°C additional upper temperature margin makes it suitable for applications requiring higher thermal tolerance. All other electrical specifications remain equivalent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and manufacturing requirements.

Q: Can I mix different manufacturers in the same circuit board assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 9V reverse standoff TVS diode category. They are electrically and mechanically interchangeable within the DO-214AA (SMB) package footprint. Mixing manufacturers is acceptable from a functional standpoint.

Q: What does the part number suffix indicate (e.g., -M3/5B, -E3/52, -TP)?

A: Part number suffixes typically indicate packaging configuration, tape reel specifications, or supplier-specific variants. These do not affect electrical performance or mechanical compatibility. All variants listed maintain the same core SMBJ9.0 base designation and are functionally equivalent.
