Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPSMB13CA 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): 34.6A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Type: Zener
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

All identified substitute parts match these core electrical and mechanical specifications, ensuring direct functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and are manufactured by established component suppliers. The TPSMB13CA and SMBJP6KE13CA-TP both carry ROHS3 compliance and support the full automotive temperature range of -65°C to 175°C. The P6SMB13CA from Eaton operates within a narrower temperature range (-55°C to 150°C) and carries standard RoHS compliance rather than ROHS3.

For applications requiring the full automotive temperature specification and AEC-Q101 qualification, the TPSMB13CA (primary part) and SMBJP6KE13CA-TP are functionally equivalent. The P6SMB13CA serves as an alternative where the reduced temperature range and standard RoHS compliance are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can P6SMB13CA be used as a direct replacement for TPSMB13CA in automotive applications?

A: P6SMB13CA matches all critical electrical parameters and package specifications. However, it operates within a narrower temperature range (-55°C to 150°C versus -65°C to 175°C) and does not carry AEC-Q101 automotive qualification. Use in automotive applications should be evaluated against specific temperature and qualification requirements.

Q: What are the key differences between SMBJP6KE13CA-TP and TPSMB13CA?

A: Both parts are electrically and mechanically equivalent with identical voltage, current, and power ratings. Both support the full temperature range and carry ROHS3 compliance. The primary difference is manufacturer: Littelfuse (TPSMB13CA) versus Micro Commercial Co (SMBJP6KE13CA-TP).

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the DO-214AA (SMB) surface mount package, ensuring identical PCB footprint and mounting compatibility.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Which part should be selected for cost optimization?

A: Selection should be based on availability, lead time, and application requirements. The P6SMB13CA from Eaton shows higher inventory availability (27,200 pcs). However, temperature range and qualification requirements must be verified against application specifications before substitution.
