Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ36CD-M3/I is determined by strict alignment of the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V or higher
• Voltage - Clamping (Max) @ Ipp: Within 57.3V ± tolerance
• Current - Peak Pulse (10/1000µs): 10.3A or higher
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The SMBJ36CA-E3/5B meets all substitution criteria as a manufacturer-recommended equivalent within the same TransZorb® series, maintaining identical standoff voltage, package configuration, and thermal operating range while delivering comparable clamping performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ36CD-M3/I and SMBJ36CA-E3/5B are active production components from Vishay General Semiconductor - Diodes Division with ROHS3 compliance and unlimited moisture sensitivity classification. Selection between these parts is based on supply chain availability and procurement channel preference, as both meet identical electrical specifications for 36V standoff voltage applications with 600W peak pulse power handling in DO-214AA surface mount packaging.

The SMBJ36CA-E3/5B is designated as the manufacturer-recommended substitute, with 5643 units currently in stock compared to 3915 units of the SMBJ36CD-M3/I. Both components operate across the full -55°C to 150°C temperature range and maintain equivalent performance characteristics for general-purpose transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can SMBJ36CA-E3/5B replace SMBJ36CD-M3/I in existing designs?

A: Yes. Both components share identical reverse standoff voltage (36V), package configuration (DO-214AA, SMB), mounting type (surface mount), and operating temperature range (-55°C ~ 150°C). The clamping voltage differential (57.3V vs. 58.1V) and peak pulse current variation (10.5A vs. 10.3A) fall within acceptable substitution parameters for general-purpose TVS applications.

Q: Are there package compatibility concerns?

A: No. Both parts use the DO-214AA (SMB) surface mount package. PCB footprints, solder pad configurations, and mounting procedures are identical.

Q: What is the significance of the voltage clamping difference?

A: The SMBJ36CA-E3/5B exhibits a maximum clamping voltage of 58.1V compared to 57.3V for the SMBJ36CD-M3/I. This 0.8V variation remains within typical design margins for transient suppression circuits and does not affect functional compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBJ36CD-M3/I and SMBJ36CA-E3/5B are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity classification. REACH status is unaffected for both components.

Q: Which part should be selected for new designs?

A: Selection is based on supply availability and procurement preference. The SMBJ36CA-E3/5B is the manufacturer-recommended equivalent with higher current inventory levels. Both parts are active production components suitable for new design implementation.
