Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB13CA-M3/5B are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 11.1V
• Voltage - Breakdown (Min): 12.4V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 33A or 33.5A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

All identified substitute parts maintain these electrical specifications and mechanical compatibility. Packaging variations (Tape & Box vs. Tape & Reel) and manufacturer differences do not affect functional performance in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the P6SMB13CA-M3/5B. Selection among equivalent parts should be based on the following factors:

Packaging Format: The P6SMB13CA-M3/5B is supplied in Tape & Box (TB) format. Direct equivalents in Tape & Reel (TR) format include P6SMB13CA-E3/52 (Vishay), P6SMB13CA TR13 PBFREE (Central Semiconductor), P6SMB13CA (Eaton), and SMBJP6KE13CA-TP (Micro Commercial). Tape & Reel packaging is standard for high-volume production environments.

Manufacturer Availability: Vishay, Central Semiconductor, Eaton, and Micro Commercial Co all maintain Active product status for their respective P6SMB13CA variants. Inventory levels vary by supplier and packaging format.

Compliance Certifications: All parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. REACH and ECCN classifications are consistent across all variants.

Operating Temperature Range: The Eaton P6SMB13CA and Micro Commercial SMBJP6KE13CA-TP variants specify a minimum operating temperature of -55°C (versus -65°C for Vishay and Central Semiconductor variants). For applications requiring operation below -55°C, Vishay or Central Semiconductor parts are required.

Peak Pulse Current: Eaton and Micro Commercial variants specify 33.5A peak pulse current, compared to 33A for Vishay and Central Semiconductor. This minor difference does not affect circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute P6SMB13CA-E3/52 for P6SMB13CA-M3/5B?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (11.1V standoff, 18.2V clamping, 33A peak pulse, 600W peak power). The primary difference is packaging format: P6SMB13CA-M3/5B uses Tape & Box, while P6SMB13CA-E3/52 uses Tape & Reel. Both are surface mount DO-214AA (SMB) packages with identical footprints and pinouts.

Q: What is the difference between Vishay P6SMB13CA and Eaton P6SMB13CA?

A: Both parts meet the core electrical requirements (11.1V standoff, 18.2V clamping, 600W peak power). The Eaton variant specifies 33.5A peak pulse current versus 33A for Vishay, and operates from -55°C to 150°C versus -65°C to 150°C for Vishay. For applications requiring the full -65°C lower temperature limit, the Vishay part is required.

Q: Is SMBJP6KE13CA-TP (Micro Commercial) compatible with P6SMB13CA-M3/5B?

A: Yes. SMBJP6KE13CA-TP maintains all critical electrical parameters: 11.1V standoff, 18.2V clamping, 33.5A peak pulse, and 600W peak power. The part uses the same DO-214AA (SMB) surface mount package. The extended operating temperature range (-55°C to 175°C) provides additional thermal margin for high-temperature applications.

Q: Can I use P6SMB13CA TR13 PBFREE (Central Semiconductor) as a direct replacement?

A: Yes. This part is electrically and mechanically equivalent to P6SMB13CA-M3/5B. It maintains 11.1V standoff, 18.2V clamping, 33A peak pulse, and 600W peak power in the same DO-214AA (SMB) package. The primary difference is the Tape & Reel packaging format and Central Semiconductor as the manufacturer.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts carry RoHS compliance certifications (ROHS3 or RoHS Compliant). All parts also maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements.

Q: What packaging formats are available for P6SMB13CA equivalents?

A: The P6SMB13CA-M3/5B is supplied in Tape & Box (TB) format. Equivalent parts are available in Tape & Reel (TR) format from Vishay (P6SMB13CA-E3/52), Central Semiconductor (P6SMB13CA TR13 PBFREE), Eaton (P6SMB13CA), and Micro Commercial (SMBJP6KE13CA-TP). All use the same DO-214AA (SMB) surface mount package with identical PCB footprints.
