SMLJ130A-TP Equivalent & Substitute Parts

Part Overview

The SMLJ130A-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 130V 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 884 pieces available in bulk packaging.

Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize procurement across multiple manufacturers while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ130A-TP are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Breakdown (Min): 144V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): 14.4A
• Power - Peak Pulse: 3000W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

The SMDJ130A from Alpha & Omega Semiconductor Inc. meets all critical electrical parameters and mechanical specifications. Both parts are classified as Transient Voltage Suppressors with identical voltage ratings, peak pulse current, and power dissipation capabilities. The primary difference is packaging format (bulk versus tape & reel) and operating temperature range, which does not affect functional substitution in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMLJ130A-TP and SMDJ130A are active production components with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on the following factors:

SMLJ130A-TP (Micro Commercial Co) is suitable when:

• Operating temperature requirements extend to 175°C junction temperature
• Bulk packaging format aligns with procurement and inventory management practices
• Direct replacement for existing designs using this manufacturer's part number

SMDJ130A (Alpha & Omega Semiconductor) is suitable when:

• Operating temperature range of -55°C to 150°C satisfies application requirements
• Tape & Reel packaging format is required for automated assembly processes
• Higher inventory availability (30,400 pieces) supports production volume requirements
• RoHS3 compliance certification is a procurement requirement

Both parts carry REACH Unaffected and EAR99 ECCN classifications, indicating equivalent regulatory compliance status. The choice between manufacturers does not introduce compliance risk in general-purpose interface protection applications.

Frequently Asked Questions (FAQ)

Q: Can SMDJ130A directly replace SMLJ130A-TP in existing circuit designs?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters: 130V reverse standoff voltage, 144V minimum breakdown voltage, 209V maximum clamping voltage, 14.4A peak pulse current, and 3000W peak pulse power. Both use the DO-214AB (SMC) surface-mount package. The substitution is valid for general-purpose interface protection applications operating within the SMDJ130A temperature range of -55°C to 150°C.

Q: What is the difference in operating temperature range between these parts?

A: The SMLJ130A-TP operates from -55°C to 175°C junction temperature, while the SMDJ130A operates from -55°C to 150°C. If your application requires sustained operation above 150°C junction temperature, the SMLJ130A-TP is the appropriate choice. For applications within the 150°C limit, both parts are functionally equivalent.

Q: Are there packaging differences that affect PCB assembly?

A: Yes. The SMLJ130A-TP is supplied in bulk packaging, while the SMDJ130A is supplied in Tape & Reel (TR) format. Both use the same DO-214AB (SMC) surface-mount package footprint and are compatible with standard pick-and-place assembly equipment. The packaging difference affects supply chain logistics and inventory management, not circuit performance or PCB layout.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts carry identical regulatory classifications: REACH Unaffected status and EAR99 ECCN designation. The SMDJ130A additionally carries RoHS3 compliance certification. Both are suitable for applications requiring standard industrial compliance documentation.

Q: What is the basis for substitution between these two part numbers?

A: Substitution is based on matching all critical electrical parameters (voltage ratings, current ratings, power dissipation), mechanical specifications (package type, mounting method), and functional classification (unidirectional Zener TVS diode). Both parts are manufactured to identical specifications within their respective operating temperature ranges and are classified as active production components.
