Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ8.0CE3/TR13 are qualified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.89V
• Bidirectional Channels: 1
• Mounting Type: Surface Mount
• Package / Case: DO-214AA or SMB equivalent
• Power - Peak Pulse: 600W
• Applications: General Purpose
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Voltage - Clamping (Max) @ Ipp: 13.6V to 15V (acceptable range for general-purpose TVS applications)
• Current - Peak Pulse (10/1000µs): 40A to 44.2A (within acceptable performance envelope)
• Operating Temperature Range: -55°C to 175°C (encompasses or overlaps primary part range)

All substitute parts listed maintain identical reverse standoff and breakdown voltage specifications, ensuring functional equivalence in circuit protection applications. Variations in clamping voltage and peak pulse current remain within acceptable tolerances for the TVS diode category and do not compromise circuit protection performance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full compliance with RoHS3 and REACH regulations, ensuring regulatory continuity and long-term availability. Selection among equivalent parts should be based on the following factors:

Voltage Clamping Consideration: The SMBJ8.0CE3/TR13 specifies a maximum clamping voltage of 15V, while all substitute parts specify 13.6V. This 1.4V difference represents improved clamping performance in the substitute options and does not compromise circuit protection. Applications requiring the higher 15V clamping specification of the original part should retain the SMBJ8.0CE3/TR13.

Temperature Range Consideration: The SMBJ8.0CA-TP (Micro Commercial Co) offers the widest operating temperature range (-55 to 175°C), providing extended thermal performance for high-temperature applications. The SMBJ8.0CA (MDD) operates within a narrower range (-50 to 150°C) and should be avoided in applications requiring operation below -50°C.

Peak Pulse Current: All substitute parts deliver peak pulse current ratings between 44.1A and 44.2A, exceeding the original part's 40A specification. This enhanced current handling provides additional design margin without introducing compatibility issues.

Inventory and Availability: Substitute parts demonstrate higher inventory levels across multiple manufacturers, supporting supply chain resilience. SMBJ8V0CA (Taiwan Semiconductor Corporation) and SMBJ8.0CA-13-F (Diodes Incorporated) each maintain inventory exceeding 4,000 units.

Frequently Asked Questions (FAQ)

Q: Can SMBJ8.0CA substitute for SMBJ8.0CE3/TR13 in all applications?

A: SMBJ8.0CA is electrically equivalent for general-purpose TVS applications. Both parts share identical reverse standoff voltage (8V) and breakdown voltage (8.89V). The substitute provides lower clamping voltage (13.6V vs. 15V) and higher peak pulse current (44.2A vs. 40A). Applications with strict clamping voltage requirements at 15V should retain the original part. The substitute is suitable for standard overvoltage protection circuits.

Q: What is the difference between SMBJ8.0CA-TP and SMBJ8V0CA?

A: Both parts are electrically identical with 8V reverse standoff, 8.89V breakdown voltage, and 13.6V clamping voltage. The primary difference is operating temperature range: SMBJ8.0CA-TP operates from -55 to 175°C, while SMBJ8V0CA operates from -55 to 150°C. SMBJ8.0CA-TP is preferred for high-temperature applications exceeding 150°C junction temperature.

Q: Are all substitute parts in the same package?

A: All substitute parts use DO-214AA (SMB) surface-mount packaging, ensuring mechanical and footprint compatibility with the original SMBJ8.0CE3/TR13. No PCB layout modifications are required when substituting between listed parts.

Q: Do substitute parts meet the same compliance standards?

A: All substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original part. Moisture sensitivity level is 1 (Unlimited) across all options, indicating no special handling requirements during storage or assembly.

Q: Which substitute part offers the best overall performance?

A: SMBJ8.0CA-TP (Micro Commercial Co) provides the widest operating temperature range (-55 to 175°C) and maintains all electrical specifications. SMBJ8V0CA (Taiwan Semiconductor Corporation) and SMBJ8.0CA-13-F (Diodes Incorporated) offer high inventory availability and standard temperature ranges suitable for most applications.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: All substitute parts are mechanically and electrically interchangeable on the same PCB without design modifications. Electrical performance differences (clamping voltage and peak pulse current) fall within acceptable tolerances for TVS diode applications and do not require circuit redesign.

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

A: The original part clamps at 15V maximum, while substitutes clamp at 13.6V. Lower clamping voltage provides better protection by limiting transient peaks to lower levels. Applications sensitive to voltage spikes above 13.6V should retain the original SMBJ8.0CE3/TR13. Most general-purpose protection circuits benefit from the improved clamping performance of substitute parts.
