SMLJ11A-TP Equivalent & Substitute Parts

Part Overview

The SMLJ11A-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 an 11V 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 1013 units available in bulk packaging. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the SMLJ11A-TP is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff: 11V
• Voltage - Breakdown (Min): 12.2V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 164.8A ± tolerance
• Power - Peak Pulse: 3000W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

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

Operational Parameters (Must Be Compatible):

• Operating Temperature Range: Substitute must support the application's required temperature window within -55°C to 175°C

The SMDJ11A from Alpha & Omega Semiconductor Inc. meets all substitution criteria with equivalent electrical specifications and identical package configuration, differing only in packaging format (Tape & Reel versus Bulk) and maximum operating temperature (150°C versus 175°C).

Parameter Comparison

*Compatible: SMDJ11A supports -55°C to 150°C. Applications requiring operation above 150°C require SMLJ11A-TP.

Engineering Selection Recommendations

SMLJ11A-TP Selection Criteria:

• Applications requiring maximum operating temperature up to 175°C (TJ)
• Bulk packaging requirements for prototype or low-volume assembly
• REACH Unaffected compliance status required
• EAR99 export classification acceptable

SMDJ11A Selection Criteria:

• Applications with maximum operating temperature requirement of 150°C or below
• Tape & Reel packaging for automated assembly and high-volume production
• RoHS3 Compliance requirement
• REACH Unaffected compliance status required
• EAR99 export classification acceptable

Both parts maintain Active product status and are suitable for general-purpose interface protection. Selection between these parts is determined by packaging format preference, production volume, and maximum operating temperature requirement of the end application.

Frequently Asked Questions (FAQ)

Q: Can SMDJ11A replace SMLJ11A-TP in all applications?

A: SMDJ11A is electrically equivalent to SMLJ11A-TP for all specified parameters. However, substitution is conditional on application operating temperature. If the circuit operates above 150°C (TJ), SMLJ11A-TP is required. For applications with maximum operating temperature of 150°C or below, SMDJ11A is a direct substitute.

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

A: Bulk packaging (SMLJ11A-TP) supplies loose components suitable for manual assembly, prototyping, and low-volume production. Tape & Reel packaging (SMDJ11A) provides components on continuous tape for automated pick-and-place assembly equipment, optimized for high-volume manufacturing.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts specify 11V reverse standoff voltage, 12.2V minimum breakdown voltage, 18.2V maximum clamping voltage, and 3000W peak pulse power. Peak pulse current differs by 0.1A (164.8A versus 164.9A), which is within normal manufacturing tolerance and does not affect substitution eligibility.

Q: Do both parts use the same package?

A: Yes. Both SMLJ11A-TP and SMDJ11A use the DO-214AB (SMC) surface-mount package with identical mechanical dimensions and PCB footprint.

Q: What compliance certifications apply to both parts?

A: Both parts carry REACH Unaffected status and EAR99 export classification. SMDJ11A additionally carries RoHS3 Compliance certification. SMLJ11A-TP REACH status is listed as REACH Unaffected.

Q: How do I determine which part to order?

A: Evaluate three factors: (1) Required packaging format (Bulk for manual assembly, Tape & Reel for automated assembly); (2) Maximum operating temperature requirement (select SMLJ11A-TP if above 150°C); (3) Compliance requirements (RoHS3 available with SMDJ11A). Both parts are electrically interchangeable within their respective temperature ratings.
