Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ16CD-M3/I is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 18.1V minimum
• Voltage - Clamping (Max) @ Ipp: within acceptable range for 16V protection class
• Current - Peak Pulse (10/1000µs): 23.4A nominal
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The SMBJ16CA-E3/5B qualifies as a manufacturer-recommended substitute because it maintains identical reverse standoff voltage (16V), equivalent breakdown voltage (17.8V), comparable clamping voltage (26V), equivalent peak pulse current (23.1A), identical power rating (600W), same package configuration (DO-214AA, SMB), identical operating temperature range, and matching RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ16CD-M3/I and SMBJ16CA-E3/5B are Active product status components from Vishay General Semiconductor - Diodes Division, ensuring ongoing manufacturer support and supply chain stability. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The SMBJ16CA-E3/5B is designated as the manufacturer-recommended substitute and demonstrates equivalent electrical performance across all critical protection parameters. Selection between these parts may be based on inventory availability, supply chain logistics, or specific procurement requirements, as both components satisfy the functional and compliance requirements for 16V TVS diode applications in the DO-214AA package.

Frequently Asked Questions (FAQ)

Q: Can SMBJ16CA-E3/5B be used as a direct replacement for SMBJ16CD-M3/I?

A: Yes. Both components share identical reverse standoff voltage (16V), equivalent breakdown voltage specifications, comparable clamping voltage performance, equivalent peak pulse current ratings, identical power dissipation capability (600W), and the same DO-214AA surface mount package. Both are ROHS3 compliant and operate across the same temperature range (-55°C to 150°C TJ).

Q: What are the key differences between these two parts?

A: The primary differences are minor variations in breakdown voltage (SMBJ16CD-M3/I: 18.1V min vs. SMBJ16CA-E3/5B: 17.8V min) and clamping voltage (SMBJ16CD-M3/I: 25.6V max vs. SMBJ16CA-E3/5B: 26V max). Peak pulse current differs slightly (SMBJ16CD-M3/I: 23.4A vs. SMBJ16CA-E3/5B: 23.1A). These variations remain within the acceptable tolerance band for 16V protection class TVS diodes.

Q: Are both parts suitable for general-purpose transient voltage suppression?

A: Yes. Both components are classified for general-purpose applications and provide equivalent transient voltage protection in the 16V protection class.

Q: What is the package compatibility between these parts?

A: Both parts use the DO-214AA (SMB) surface mount package with identical pinout and footprint, ensuring direct PCB compatibility without layout modifications.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both SMBJ16CD-M3/I and SMBJ16CA-E3/5B are ROHS3 compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement and use.
