Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Minimal Parameter Variance):

The SMCJ7.0CA and SMCJ7.0CA-TP parts from Taiwan Semiconductor Corporation and Micro Commercial Co respectively provide the closest electrical equivalence to the SMCJ7.0CE3/TR13. Both maintain identical reverse standoff voltage (7V), matching breakdown voltage (7.78V to 7.8V), and equivalent clamping voltage (12V). Peak pulse current ratings of 131A and 125A respectively exceed the original 112.8A specification. Both are RoHS3 compliant and carry active product status. The SMCJ7.0CA-TP variant offers extended operating temperature range to 175°C.

Higher Power Capability Alternatives:

The SMDJ7.0CA (Alpha & Omega Semiconductor Inc.) and SMLJ7.0CA (Bourns Inc.) provide doubled peak pulse power dissipation (3000W versus 1500W) while maintaining identical voltage parameters and DO-214AB packaging. These components accommodate higher transient energy levels with peak pulse currents of 250A. Both maintain RoHS3 compliance and active product status. The SMLJ7.0CA carries REACH Affected status, whereas other substitutes are REACH Unaffected.

Marginal Voltage Deviation:

The 1.5SMC8.2CA from Taiwan Semiconductor Corporation exhibits slightly lower clamping voltage (12.1V versus 13.3V) and marginally higher reverse standoff voltage (7.02V versus 7V). This part delivers 130A peak pulse current at 1500W power dissipation. RoHS3 compliance and active product status are confirmed.

All substitute parts maintain DO-214AB (SMC) surface-mount packaging, enabling direct mechanical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ7.0CA be used as a direct replacement for SMCJ7.0CE3/TR13?

A: Yes. Both parts share identical reverse standoff voltage (7V), matching breakdown voltage specifications (7.78V), and equivalent clamping voltage (12V). The SMCJ7.0CA delivers 131A peak pulse current, exceeding the original 112.8A requirement. Both are RoHS3 compliant, active products in DO-214AB packaging. The primary difference is the operating temperature range: SMCJ7.0CE3/TR13 operates to -65°C, while SMCJ7.0CA operates to -55°C.

Q: What is the difference between 1500W and 3000W power-rated TVS diodes?

A: Power rating indicates peak pulse power dissipation capacity during transient events. The SMDJ7.0CA and SMLJ7.0CA rated at 3000W accommodate twice the transient energy compared to 1500W-rated parts. Selection depends on circuit transient energy levels. Both maintain identical voltage parameters and DO-214AB packaging.

Q: Are all substitute parts compatible with existing PCB layouts?

A: Yes. All substitute parts use DO-214AB (SMC) surface-mount packaging with identical mechanical dimensions and pin configurations. Direct PCB footprint compatibility is confirmed across all listed substitutes.

Q: What does RoHS3 compliance indicate?

A: RoHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting specified hazardous materials including lead, cadmium, and mercury. All listed parts maintain RoHS3 compliance.

Q: How does operating temperature range affect part selection?

A: Operating temperature range specifies the junction temperature limits for reliable device operation. The SMCJ7.0CE3/TR13 operates from -65°C to 150°C, providing extended low-temperature capability. The SMCJ7.0CA-TP extends the upper limit to 175°C. Selection depends on application thermal requirements.

Q: What is the significance of reverse standoff voltage matching?

A: Reverse standoff voltage (7V) defines the maximum voltage the TVS diode sustains without conducting. Matching this parameter ensures the device remains inactive during normal circuit operation and activates only during overvoltage transients. All listed substitutes maintain 7V reverse standoff voltage.

Q: Can SMDJ7.0CA replace SMCJ7.0CE3/TR13 in all applications?

A: SMDJ7.0CA provides equivalent voltage protection with doubled power dissipation capacity (3000W versus 1500W). It is suitable for applications requiring higher transient energy handling. Electrical parameters match the original part. Mechanical compatibility is confirmed through identical DO-214AB packaging.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. Components with this rating do not require special moisture-control storage or handling procedures, simplifying inventory management and supply chain logistics.
