Substitute Part Grouping Explanation

Substitute parts for the SMBJ90CA-M3/52 are identified based on electrical parameter equivalence within the allowed tolerance range for TVS diode applications. The substitution criteria are strictly limited to the following parameters:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V
• Voltage - Clamping (Max) @ Ipp: 146V
• Current - Peak Pulse (10/1000µs): 4.1A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part SMBJ90CA (MDD manufacturer) meets all electrical and mechanical parameters required for direct substitution in the same application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ90CA-M3/52 (Vishay) and SMBJ90CA (MDD) are active production parts with ROHS3 compliance and MSL Level 1 rating. The electrical specifications are identical across all critical parameters: 90V reverse standoff voltage, 100V minimum breakdown voltage, 146V maximum clamping voltage, and 4.1A peak pulse current. Both components are packaged in DO-214AA/SMB surface mount format suitable for automated assembly.

The operating temperature range differs slightly: the Vishay part operates from -55°C to 150°C, while the MDD part operates from -50°C to 150°C. This difference is not a limiting factor for general-purpose applications operating within the -50°C to 150°C range. Selection between these parts should be based on availability, lead time, and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90CA (MDD) be used as a direct replacement for SMBJ90CA-M3/52 (Vishay)?

A: Yes. Both parts share identical electrical specifications for voltage suppression (90V standoff, 146V clamping), current handling (4.1A peak pulse), and package format (DO-214AA/SMB surface mount). Both are ROHS3 compliant with MSL Level 1 rating.

Q: What is the difference in operating temperature range between these parts?

A: The Vishay SMBJ90CA-M3/52 operates from -55°C to 150°C, while the MDD SMBJ90CA operates from -50°C to 150°C. For applications requiring operation below -50°C, the Vishay part is required. For applications within -50°C to 150°C, both parts are equivalent.

Q: Are the package dimensions identical?

A: Both parts use the DO-214AA/SMB surface mount package format, ensuring identical PCB footprint and automated assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBJ90CA-M3/52 and SMBJ90CA are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080.

Q: What applications are these TVS diodes suitable for?

A: Both parts are rated for general-purpose transient voltage suppression applications requiring 90V reverse standoff protection with 600W peak pulse power handling capability.
