SMLJ5.0CA-TP Equivalent & Substitute Parts

Part Overview

The SMLJ5.0CA-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose interface protection applications. This surface-mount component operates with a 5V reverse standoff voltage and provides 9.2V clamping at peak pulse current, delivering 3000W peak pulse power dissipation. The part is currently in active production status with 811 pieces available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified components that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The SMLJ5.0CA-TP qualifies for substitution with parts that maintain identical specifications in the following critical areas:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 326A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 3000W

Mechanical Compatibility Criteria:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

The SMDJ5.0CA manufactured by Alpha & Omega Semiconductor Inc. meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the SMLJ5.0CA-TP.

Parameter Comparison

Engineering Selection Recommendations

SMDJ5.0CA Substitution Suitability:

The SMDJ5.0CA is electrically and mechanically equivalent to the SMLJ5.0CA-TP across all critical performance parameters. Both components are in active production status, ensuring long-term availability and supply chain stability.

Temperature Range Consideration:

The SMDJ5.0CA operates across a maximum junction temperature range of -55°C to 150°C, compared to the SMLJ5.0CA-TP range of -55°C to 175°C. Applications requiring sustained operation above 150°C junction temperature must retain the SMLJ5.0CA-TP. For applications with maximum junction temperatures at or below 150°C, the SMDJ5.0CA provides full functional equivalence.

Compliance Status:

The SMDJ5.0CA carries RoHS3 compliance certification. Both parts maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, supporting regulatory and trade documentation requirements.

Inventory Availability:

The SMDJ5.0CA maintains significantly higher inventory levels (17,300 pieces) compared to the SMLJ5.0CA-TP (811 pieces), supporting supply chain continuity and lead-time reduction when substitution is permissible.

Frequently Asked Questions (FAQ)

Q: Can SMDJ5.0CA replace SMLJ5.0CA-TP in all applications?

A: The SMDJ5.0CA provides electrical and mechanical equivalence for applications where the maximum junction temperature does not exceed 150°C. Applications requiring operation above 150°C junction temperature must use the SMLJ5.0CA-TP.

Q: Are the DO-214AB and SMC packages identical?

A: DO-214AB and SMC refer to the same surface-mount package designation. Both the SMLJ5.0CA-TP and SMDJ5.0CA use this identical package, ensuring PCB footprint and reflow process compatibility.

Q: What is the significance of the 0.1A difference in peak pulse current?

A: The SMDJ5.0CA specifies 326.1A peak pulse current versus 326A for the SMLJ5.0CA-TP. This 0.1A variance falls within normal manufacturing tolerance for TVS diodes and does not affect functional equivalence or circuit protection performance.

Q: Do both parts require identical PCB layout and thermal management?

A: Yes. Both components share identical electrical ratings, package geometry, and thermal characteristics. PCB layout, thermal vias, and heat dissipation design remain unchanged when substituting SMDJ5.0CA for SMLJ5.0CA-TP.

Q: What compliance certifications apply to substitution?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The SMDJ5.0CA additionally carries RoHS3 compliance, which does not restrict its use as a substitute in applications already qualified for the SMLJ5.0CA-TP.
