SZP6SMB130AT3G Equivalent & Substitute Parts

Part Overview

The SZP6SMB130AT3G is an active Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for surface mount applications in the SMB package. This unidirectional Zener diode provides transient voltage protection with a reverse standoff voltage of 111V and clamping voltage of 179V at peak pulse current. The component is AEC-Q101 qualified for automotive applications and RoHS3 compliant. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SZP6SMB130AT3G is determined by equivalence in the following critical parameters:

• Voltage - Reverse Standoff: 111V (Typ)
• Voltage - Breakdown: 124V (Min)
• Voltage - Clamping: 179V (Max) @ Ipp
• Current - Peak Pulse: 3.3A minimum (10/1000µs)
• Power - Peak Pulse: 600W
• Package: DO-214AA / SMB surface mount
• Unidirectional Zener type configuration

The identified substitute parts P6SMB130A (Eaton) and P6SMB130A-E3/52 (Vishay) meet these electrical specifications and mechanical requirements. Both maintain the same voltage protection characteristics, peak pulse power rating, and surface mount package compatibility. Peak pulse current specifications for substitutes are 3.4A, which exceeds the minimum 3.3A requirement of the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet the core electrical and mechanical requirements for TVS diode substitution in the 111V reverse standoff category.

The SZP6SMB130AT3G (Littelfuse) carries AEC-Q101 automotive qualification and ROHS3 compliance, making it suitable for automotive-grade applications requiring formal qualification documentation.

The P6SMB130A (Eaton) is RoHS compliant with a minimum operating temperature of -55°C, which is 10°C higher than the main part. This part is suitable for applications where the lower temperature bound is not critical.

The P6SMB130A-E3/52 (Vishay) is ROHS3 compliant with an operating temperature range of -65°C to 150°C, matching the main part specification. This part carries the TransZorb® series designation and maintains full temperature range equivalence.

Selection should be based on supply availability, procurement lead times, and specific application temperature requirements. All parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can P6SMB130A be used as a direct replacement for SZP6SMB130AT3G?

A: Yes, the P6SMB130A meets all critical electrical parameters: 111V reverse standoff, 124V breakdown minimum, and 179V clamping voltage. The 3.4A peak pulse current exceeds the 3.3A requirement. The primary consideration is the operating temperature minimum of -55°C versus -65°C for the original part. Verify application temperature requirements before selection.

Q: What is the difference between P6SMB130A and P6SMB130A-E3/52?

A: Both parts are electrically equivalent with identical voltage and current ratings. The P6SMB130A-E3/52 is manufactured by Vishay and carries the TransZorb® series designation. The P6SMB130A-E3/52 maintains the full -65°C to 150°C operating temperature range, while the Eaton P6SMB130A operates from -55°C to 150°C. Package and mounting type are identical (DO-214AA, SMB).

Q: Are all substitute parts RoHS compliant?

A: Yes. The SZP6SMB130AT3G and P6SMB130A-E3/52 are ROHS3 compliant. The P6SMB130A is RoHS compliant. All three parts meet RoHS requirements for lead-free construction.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in automotive applications?

A: The SZP6SMB130AT3G carries AEC-Q101 automotive qualification. The substitute parts do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring formal qualification documentation, verify that the selected substitute meets your specific qualification requirements.

Q: What is the peak pulse power rating for all parts?

A: All three parts have a peak pulse power rating of 600W at the specified 10/1000µs pulse duration, ensuring equivalent transient energy absorption capability.
