Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ64CA-M3/5B are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): 5.8A (±0.03A tolerance acceptable)
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1

All qualified substitutes maintain identical functional performance within the specified electrical envelope and are compatible with existing PCB layouts and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and MSL Level 1 certification. Selection among these substitutes should be based on:

1. Inventory availability and lead time requirements
2. Packaging format preference (Tape & Reel, Cut Tape, or Digi-Reel)
3. Manufacturer qualification requirements for your application
4. Voltage breakdown specification tolerance (71.7V vs. 71.1V minimum)

The SMBJ64CA (Meritek) offers the highest inventory availability at 35,400 pieces. The SMBJ64CA-E3/5B (Vishay) provides the largest stock among Vishay variants at 4,001 pieces. All parts maintain identical clamping voltage and peak pulse power ratings within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64CA-E3/5B replace SMBJ64CA-M3/5B directly?

A: Yes. Both are Vishay TransZorb® series components with identical electrical specifications (64V standoff, 103V clamping, 5.8A peak pulse), DO-214AA package, and operating temperature range. The difference is in packaging format (Tape & Reel variant designation).

Q: What is the difference between the Meritek SMBJ64CA and Vishay variants?

A: The Meritek part maintains all critical electrical parameters (64V standoff, 103V clamping, 5.83A peak pulse) and DO-214AA package compatibility. The primary difference is manufacturer origin and packaging designation. Voltage breakdown minimum is 71.1V versus 71.7V for the original part.

Q: Are all substitutes compatible with existing PCB layouts?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint. No PCB redesign is required.

Q: Do all parts meet the same compliance standards?

A: Yes. All four parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). All are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Which substitute offers the best availability?

A: The Meritek SMBJ64CA provides the highest inventory at 35,400 pieces. For Vishay-specific sourcing, the SMBJ64CA-E3/5B variant offers 4,001 pieces in stock.

Q: Can I mix manufacturers in the same design?

A: Yes. All parts meet identical electrical specifications and package requirements. Mixed sourcing is permissible provided your design documentation and procurement process account for multiple manufacturer sources.
