Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ90CA-M3/9AT are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V
• Voltage - Clamping (Max) @ Ipp: 146V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (1500W Peak Pulse) Parts with identical peak pulse power rating (1500W) and peak pulse current (10.3A). These provide direct functional replacement with no derating considerations.

Category 2: Higher Power Rated Alternatives (3000W - 5000W Peak Pulse) Parts with elevated peak pulse power ratings (3000W or 5000W) and correspondingly higher peak pulse currents (20.6A or 34.3A). These provide enhanced transient protection capability while maintaining voltage specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (1500W Category): SMCJ90CA-13-F (Diodes Incorporated) and SMCJ90CA-TP (Micro Commercial Co) provide direct functional equivalence to SMCJ90CA-M3/9AT with identical electrical specifications and 1500W peak pulse power rating. Both are RoHS3 compliant and available in Tape & Reel packaging. SMCJ90CA-TP offers extended operating temperature range (-55°C to 175°C) compared to the primary part (-55°C to 150°C).

Enhanced Protection (3000W Category): SMDJ90CA (Alpha & Omega Semiconductor Inc.) and SMLJ90CA-TP (Micro Commercial Co) provide doubled peak pulse current (20.6A) and power dissipation (3000W) while maintaining identical voltage specifications. These are suitable for applications requiring higher transient energy absorption. SMLJ90CA-TP offers extended temperature range (-55°C to 175°C).

Maximum Protection (5000W Category): 5.0SMLJ90CA-TP (Micro Commercial Co) provides the highest peak pulse current (34.3A) and power dissipation (5000W) with extended operating temperature range (-55°C to 175°C). This part is specified for applications with severe transient stress requirements.

All substitute parts maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity level. Selection should be based on application transient energy requirements and thermal management capabilities.

Frequently Asked Questions (FAQ)

Q: Can SMCJ90CA-TP be used as a direct replacement for SMCJ90CA-M3/9AT? A: Yes. Both parts share identical voltage specifications (90V reverse standoff, 100V breakdown, 146V clamping) and peak pulse power rating (1500W). The primary difference is packaging format (Tape & Reel vs. Tape & Reel) and extended operating temperature range on SMCJ90CA-TP (-55°C to 175°C vs. -55°C to 150°C).

Q: What is the difference between 1500W, 3000W, and 5000W rated parts? A: These ratings reflect peak pulse power dissipation capability. The 1500W parts (SMCJ90CA series) handle 10.3A peak pulse current. The 3000W parts (SMDJ90CA, SMLJ90CA series) handle 20.6A. The 5000W parts (5.0SMLJ90CA-TP) handle 34.3A. All maintain identical voltage clamping characteristics. Higher power ratings provide greater transient energy absorption for demanding applications.

Q: Are all substitute parts in the same package? A: Yes. All listed substitute parts use the DO-214AB (SMC) surface mount package, ensuring mechanical and footprint compatibility with SMCJ90CA-M3/9AT.

Q: What compliance certifications apply to these parts? A: All substitute parts listed are RoHS3 compliant. SMLJ90CA (Bourns Inc.) is REACH Affected; all other parts are REACH Unaffected. All parts carry ECCN EAR99 classification and HTSUS code 8541.10.0080.

Q: Can higher power rated parts be used in place of the original 1500W part? A: Yes. Higher power rated parts (3000W or 5000W) provide equivalent or superior voltage protection with enhanced transient energy handling. They are electrically compatible and mechanically interchangeable. Selection depends on application transient stress levels and thermal design margins.

Q: What is the difference between Tape & Reel and Bulk packaging? A: Tape & Reel packaging is suitable for automated assembly processes. Bulk packaging is typically used for manual assembly or lower-volume applications. Electrical specifications remain identical regardless of packaging format.
