Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ5.0CA-13 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 65.2A ± tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications. Variations in operating temperature range, packaging format (tape & reel vs. cut tape), and manufacturer compliance certifications do not affect electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the SMBJ5.0CA-13 and are suitable for direct replacement in circuit applications. Selection among available substitutes should be based on the following factors:

Product Availability & Status: SMBJ5.0CA-13-F (Diodes Incorporated) is the direct equivalent from the original manufacturer and maintains active product status with high inventory availability (7493 pcs). This part is recommended as the primary substitute when sourcing from the original manufacturer is required.

Compliance & Certification: All substitute parts listed are RoHS3 compliant except the original SMBJ5.0CA-13 (RoHS non-compliant). SMBJ5.0CA-HR carries REACH Affected status, while all other parts are REACH Unaffected. For applications requiring specific compliance certifications, verify requirements against the selected substitute.

Operating Temperature Range: SMBJ5.0CA-TP offers an extended upper operating temperature limit of 175°C compared to the standard 150°C, providing additional thermal margin for high-temperature applications. SMBJ5.0CA and SMBJ5.0CA-HR support extended lower temperature operation to -65°C.

Packaging Format: SMBJ5.0CA-13-F, SMBJ5.0CA-E3/52, SMBJ5.0CA-TP, and SMBJ5.0CA-HR are supplied in tape & reel format suitable for automated assembly. SMBJ5.0CA and SMBJ5V0CA are available in cut tape format. Select based on production assembly requirements.

Inventory & Lead Time: MDD SMBJ5.0CA offers the highest inventory level (49305 pcs), followed by Vishay SMBJ5.0CA-E3/52 (33086 pcs), providing optimal availability for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can SMBJ5.0CA-13-F be used as a direct replacement for SMBJ5.0CA-13?

A: Yes. SMBJ5.0CA-13-F is manufactured by Diodes Incorporated and maintains identical electrical specifications (5V standoff, 9.2V clamping, 65.2A peak pulse current) and mechanical package (DO-214AA, SMB). The primary difference is packaging format (tape & reel) and active product status. This is the recommended substitute from the original manufacturer.

Q: Are there any electrical differences between the Diodes Incorporated and MDD versions?

A: The MDD SMBJ5.0CA exhibits a peak pulse current specification of 65.3A compared to 65.2A for the Diodes version. This 0.1A difference is within normal manufacturing tolerance and does not affect functional equivalence. Both parts maintain the same 5V standoff voltage, 9.2V clamping voltage, and 600W peak pulse power rating.

Q: Which substitute offers the widest operating temperature range?

A: SMBJ5.0CA-TP (Micro Commercial Co) supports -55°C to 175°C, providing the highest upper temperature limit. SMBJ5.0CA (MDD) and SMBJ5.0CA-HR (Littelfuse) support -65°C to 150°C, offering the lowest lower temperature limit.

Q: What is the difference between tape & reel and cut tape packaging?

A: Tape & reel packaging is supplied on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Cut tape is supplied in shorter tape segments, suitable for manual assembly or lower-volume production. Both formats contain identical components; selection depends on assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are RoHS3 compliant. The original SMBJ5.0CA-13 is RoHS non-compliant. SMBJ5.0CA-HR carries REACH Affected status; all other substitutes are REACH Unaffected. Verify compliance requirements for your specific application before selection.

Q: Can I use SMBJ5V0CA as a substitute?

A: Yes. SMBJ5V0CA (Taiwan Semiconductor Corporation) maintains all critical electrical specifications: 5V standoff voltage, 6.4V breakdown voltage, 9.2V clamping voltage, 65.2A peak pulse current, and 600W peak pulse power. The part number variant reflects manufacturer nomenclature but does not indicate functional differences.
