SMLJ110CA-TP Equivalent & Substitute Parts

Part Overview

The SMLJ110CA-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 110V reverse standoff voltage and provides 3000W peak pulse power dissipation in a compact DO-214AB (SMC) package. The part is currently in active production status with 826 pieces available in bulk packaging. Substitute parts are identified to address inventory availability, packaging format preferences, or supply chain requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLJ110CA-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Power - Peak Pulse: 3000W
• Bidirectional Channels: 1
• Type: Zener

Mechanical Equivalence Requirements:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Acceptable Variation:

• Current - Peak Pulse (10/1000µs): ±0.2A tolerance permitted (16.8A nominal)
• Operating Temperature Range: Minimum -55°C required; maximum temperature may vary
• Packaging Format: Bulk or Tape & Reel (TR) both acceptable for substitution purposes

The SMDJ110CA substitute part meets all electrical and mechanical equivalence criteria and is therefore a valid substitute for the SMLJ110CA-TP.

Parameter Comparison

Engineering Selection Recommendations

SMDJ110CA as Substitute for SMLJ110CA-TP:

The SMDJ110CA is electrically and mechanically equivalent to the SMLJ110CA-TP across all critical transient voltage suppression parameters. Both components are active-status products manufactured to identical electrical specifications for the 110V protection class.

Considerations for Selection:

1. Operating Temperature Range: The SMLJ110CA-TP supports operation to 175°C junction temperature, while the SMDJ110CA is rated to 150°C. Applications requiring sustained operation above 150°C junction temperature must use the SMLJ110CA-TP.

2. Packaging Format: The SMLJ110CA-TP is supplied in bulk packaging, while the SMDJ110CA is supplied in Tape & Reel format. Selection depends on assembly process requirements and volume handling procedures.

3. Inventory and Supply: The SMDJ110CA offers significantly higher inventory availability (30200 pieces versus 826 pieces), which may influence lead time and supply chain continuity.

4. Compliance: Both parts carry REACH Unaffected status and EAR99 ECCN classification. The SMDJ110CA additionally carries RoHS3 Compliant certification.

Frequently Asked Questions (FAQ)

Q: Can SMDJ110CA replace SMLJ110CA-TP in all applications?

A: The SMDJ110CA is electrically and mechanically equivalent for general-purpose interface protection applications. However, if your application requires sustained junction temperatures above 150°C, the SMLJ110CA-TP must be used due to its 175°C maximum rating.

Q: What is the difference in peak pulse current between these parts?

A: The SMLJ110CA-TP is rated at 16.8A peak pulse current, while the SMDJ110CA is rated at 17A. This 0.2A difference is within normal manufacturing tolerance and does not affect substitution eligibility for the 3000W power class.

Q: Are the packages physically identical?

A: Yes. Both the SMLJ110CA-TP and SMDJ110CA use the DO-214AB (SMC) surface-mount package with identical footprint and pinout. They are mechanically interchangeable on PCB assemblies.

Q: Does packaging format (Bulk vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly process compatibility. Electrical and thermal performance are identical regardless of packaging format.

Q: What compliance certifications apply to both parts?

A: Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The SMDJ110CA additionally carries RoHS3 Compliant certification.

Q: Can I mix SMLJ110CA-TP and SMDJ110CA in the same production batch?

A: Yes, from an electrical and mechanical standpoint. However, assembly process procedures may require separate handling due to different packaging formats (bulk versus tape & reel).
