SMLJ9.0CA-TP Equivalent & Substitute Parts

Part Overview

The SMLJ9.0CA-TP is a bidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose interface protection applications. This surface-mount component operates with a 9V 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 744 units 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 SMLJ9.0CA-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Breakdown (Min): 10V
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Current - Peak Pulse (10/1000µs): ≥194.8A
• Power - Peak Pulse: 3000W (3kW)
• Bidirectional Channels: 1
• Type: Zener

Mechanical Equivalence Requirements:

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

The SMDJ9.0CA manufactured by Alpha & Omega Semiconductor Inc. meets all electrical and mechanical equivalence criteria. Differences in packaging format (Tape & Reel vs. Bulk) and operating temperature maximum (150°C vs. 175°C) do not affect functional substitution for general-purpose interface protection applications.

Engineering Selection Recommendations

SMDJ9.0CA Selection Criteria:

The SMDJ9.0CA is a direct electrical equivalent to the SMLJ9.0CA-TP with identical clamping voltage, breakdown voltage, and peak pulse current specifications. Both components are active products with REACH Unaffected status and EAR99 export classification.

Packaging Consideration: The SMDJ9.0CA is supplied in Tape & Reel (TR) format, whereas the SMLJ9.0CA-TP is supplied in Bulk packaging. Selection between these formats depends on assembly process requirements and volume handling procedures.

Temperature Operating Range: The SMDJ9.0CA specifies a maximum junction temperature of 150°C compared to 175°C for the SMLJ9.0CA-TP. For applications operating continuously near or above 150°C junction temperature, the SMLJ9.0CA-TP is the appropriate selection. For general-purpose interface protection within standard operating ranges, this difference does not impact functional performance.

Compliance Status: Both parts maintain equivalent regulatory compliance with REACH Unaffected designation and EAR99 classification, supporting identical supply chain and export requirements.

Frequently Asked Questions (FAQ)

Q: Can SMDJ9.0CA replace SMLJ9.0CA-TP in existing designs?

A: Yes. The SMDJ9.0CA meets all electrical equivalence criteria: 9V reverse standoff voltage, 10V minimum breakdown voltage, 15.4V clamping voltage, 194.9A peak pulse current, and 3000W peak pulse power. Both use identical DO-214AB (SMC) surface-mount packages. Substitution is valid for general-purpose interface protection applications.

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging supplies loose components suitable for manual handling or small-volume assembly. Tape & Reel (TR) packaging supplies components on continuous carrier tape for automated pick-and-place assembly equipment. Selection depends on manufacturing process capabilities and volume requirements.

Q: Does the 25°C difference in maximum operating temperature affect substitution?

A: The SMDJ9.0CA maximum junction temperature of 150°C versus 175°C for SMLJ9.0CA-TP does not affect substitution for applications operating within standard temperature ranges. Applications requiring sustained operation above 150°C junction temperature require the SMLJ9.0CA-TP.

Q: Are both parts currently available?

A: Both parts maintain active product status. SMLJ9.0CA-TP has 744 units in bulk inventory. SMDJ9.0CA has 30,300 units in Tape & Reel inventory. Availability should be confirmed with the supplier for current requirements.

Q: Do both parts have identical regulatory compliance?

A: Yes. Both SMLJ9.0CA-TP and SMDJ9.0CA are REACH Unaffected and classified as EAR99 for export purposes, supporting identical regulatory and supply chain requirements.
