SMLJ100A-TP Equivalent & Substitute Parts

Part Overview

The SMLJ100A-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 100V 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 801 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 SMLJ100A-TP is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 100V
• Voltage - Breakdown (Min): 111V
• Voltage - Clamping (Max) @ Ipp: 162V
• Current - Peak Pulse (10/1000µs): 18.6A
• 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: Must support minimum -55°C to 150°C (substitute may have higher upper limit)

The SMDJ100A from Alpha & Omega Semiconductor Inc. meets all electrical and mechanical equivalence criteria. The primary difference is packaging format (Tape & Reel versus Bulk) and operating temperature upper limit (150°C versus 175°C), which does not preclude substitution in applications operating within the lower temperature ceiling.

Parameter Comparison

*Compatible: SMDJ100A supports the full operating range of SMLJ100A-TP applications up to 150°C. Applications requiring operation above 150°C require SMLJ100A-TP.

Engineering Selection Recommendations

SMLJ100A-TP Selection Criteria:

• Applications requiring operating temperatures above 150°C (up to 175°C)
• Bulk packaging format preference for manufacturing processes
• Micro Commercial Co supply chain integration

SMDJ100A Selection Criteria:

• Standard production environments with operating temperatures up to 150°C
• Tape & Reel packaging format for automated assembly lines
• Alpha & Omega Semiconductor Inc. supply chain availability
• High inventory availability (23,200 pieces in stock)
• RoHS3 compliance requirement

Both parts carry REACH Unaffected and EAR99 ECCN classifications. Selection between these parts should be based on temperature operating range requirements, packaging format compatibility with assembly equipment, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can SMDJ100A replace SMLJ100A-TP in all applications?

A: SMDJ100A is electrically and mechanically equivalent to SMLJ100A-TP for applications operating at junction temperatures up to 150°C. Applications requiring operation above 150°C must use SMLJ100A-TP, which is rated to 175°C.

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

A: Bulk packaging (SMLJ100A-TP) is supplied loose in containers, suitable for manual assembly or small-volume production. Tape & Reel packaging (SMDJ100A) is wound on continuous tape for automated pick-and-place assembly equipment, standard in high-volume manufacturing.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts have identical voltage ratings (100V standoff, 111V breakdown minimum, 162V clamping maximum), peak pulse current (18.6A), and power dissipation (3000W). They are electrically interchangeable within their respective temperature operating ranges.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the DO-214AB (SMC) surface-mount package, which has identical physical dimensions and land pattern requirements. No PCB redesign is necessary when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both SMLJ100A-TP and SMDJ100A are REACH Unaffected and classified as EAR99 for export control purposes. SMDJ100A additionally carries RoHS3 compliance certification.

Q: Which part should be selected for new designs?

A: For new designs with standard operating temperature requirements (up to 150°C), SMDJ100A is recommended due to higher inventory availability and RoHS3 compliance. For designs requiring extended temperature operation or bulk packaging, SMLJ100A-TP is the appropriate selection.
