Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ130CA-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
• Bidirectional Channels: 1
• Type: Zener
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

The SMDJ130CA manufactured by Alpha & Omega Semiconductor Inc. meets all critical electrical parameters and package specifications. Both components share identical voltage ratings, peak pulse current capacity, and power dissipation characteristics. The primary difference is packaging format (Tape & Reel versus Bulk) and operating temperature range maximum specification.

Parameter Comparison

Engineering Selection Recommendations

SMDJ130CA Substitution Criteria:

The SMDJ130CA is a direct electrical equivalent to the SMLJ130CA-TP for applications operating within the temperature range of -55°C to 150°C (TJ). Both components are active products with identical REACH and ECCN compliance status, ensuring regulatory consistency.

Temperature Consideration:

The SMLJ130CA-TP supports operation up to 175°C (TJ), while the SMDJ130CA is rated to 150°C (TJ). Applications requiring sustained operation above 150°C junction temperature must use the SMLJ130CA-TP or identify alternative parts with higher temperature ratings.

Packaging Format:

The SMLJ130CA-TP is supplied in Bulk packaging, while the SMDJ130CA is supplied in Tape & Reel (TR) format. Selection between these formats depends on manufacturing process requirements and inventory management practices. Both formats contain identical components with matching electrical specifications.

Supply Chain Availability:

The SMDJ130CA maintains significantly higher inventory availability (59,495 pieces) compared to the SMLJ130CA-TP (868 pieces), making it suitable for high-volume production requirements or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can SMDJ130CA replace SMLJ130CA-TP in all applications?

A: The SMDJ130CA is electrically equivalent for applications operating within -55°C to 150°C junction temperature range. Applications requiring operation above 150°C must use the SMLJ130CA-TP or identify alternative components with higher temperature ratings.

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

A: Bulk packaging contains loose components suitable for manual assembly or small-batch operations. Tape & Reel (TR) packaging provides components on continuous tape for automated pick-and-place assembly systems. Both packaging formats contain identical electrical components.

Q: Are there compliance differences between these parts?

A: Both the SMLJ130CA-TP and SMDJ130CA share identical REACH, ECCN (EAR99), and HTSUS code classifications. No compliance differentiation exists between these components.

Q: How do the electrical specifications compare?

A: All critical electrical parameters are identical: 130V reverse standoff voltage, 144V minimum breakdown voltage, 209V maximum clamping voltage, 14.4A peak pulse current, and 3000W peak pulse power. Both components are unidirectional Zener TVS diodes in DO-214AB (SMC) packages.

Q: Which part should be selected for new designs?

A: For applications operating within -55°C to 150°C, either part is suitable. The SMDJ130CA offers higher inventory availability. For applications requiring operation above 150°C or bulk packaging format, the SMLJ130CA-TP is required.

Q: Are there any performance differences in transient suppression?

A: No. Both components provide identical transient voltage suppression performance with matching clamping characteristics and peak pulse ratings across the specified operating temperature ranges.
