Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB130A-M3/52 are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 111V
• Voltage - Breakdown (Min): 124V
• Voltage - Clamping (Max) @ Ipp: 179V
• Current - Peak Pulse (10/1000µs): 3.4A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB

Substitutes are grouped into two categories:

Category 1: Direct Manufacturer Equivalents (Vishay) Parts P6SMB130A-E3/52 share identical electrical specifications and differ only in packaging format (Tape & Reel vs. Tape & Box).

Category 2: Cross-Manufacturer Equivalents Parts P6SMB130A (Eaton) and SZP6SMB130AT3G (Littelfuse) meet all critical electrical parameters and package requirements, with minor variations in operating temperature range and certifications.

Parameter Comparison

Engineering Selection Recommendations

P6SMB130A-E3/52 (Vishay) This part is a direct equivalent to the P6SMB130A-M3/52, differing only in packaging format (Tape & Reel instead of Tape & Box). Both are ROHS3 compliant and manufactured by Vishay. Selection is appropriate when Tape & Reel packaging is acceptable for assembly processes. Inventory availability is higher (3864 units).

P6SMB130A (Eaton) This part meets all critical electrical specifications and is RoHS compliant. The operating temperature range is -55°C ~ 150°C (TJ), which is narrower than the Vishay variant by 10°C at the lower bound. Selection is appropriate for applications where the minimum operating temperature requirement does not exceed -55°C. Inventory availability is highest (6400 units).

SZP6SMB130AT3G (Littelfuse) This part is manufacturer-recommended and meets all critical electrical specifications with ROHS3 compliance. Peak pulse current is specified as 3.3A, which is 0.1A lower than the primary part. The device carries AEC-Q101 automotive qualification and operates across -65°C ~ 150°C (TJ). Selection is appropriate for automotive applications or when automotive-grade qualification is required. Inventory availability is 3263 units.

Frequently Asked Questions (FAQ)

Q: Can P6SMB130A-E3/52 be used as a direct replacement for P6SMB130A-M3/52? A: Yes. Both parts are manufactured by Vishay with identical electrical specifications, RoHS3 compliance, and MSL rating. The only difference is packaging format (Tape & Reel vs. Tape & Box). Compatibility depends on assembly equipment capability to handle the respective packaging format.

Q: What is the difference between the Eaton P6SMB130A and the Vishay P6SMB130A-M3/52? A: The Eaton part has an operating temperature range of -55°C ~ 150°C (TJ) compared to -65°C ~ 150°C (TJ) for the Vishay part. All other electrical parameters are identical. Use the Eaton part only if your application does not require operation below -55°C.

Q: Is the Littelfuse SZP6SMB130AT3G suitable for non-automotive applications? A: Yes. The Littelfuse part meets all electrical specifications for the P6SMB130A-M3/52 and is ROHS3 compliant. Automotive qualification (AEC-Q101) is an additional feature that does not restrict use in general-purpose applications. The 0.1A difference in peak pulse current (3.3A vs. 3.4A) is within acceptable tolerance for most applications.

Q: Are all substitute parts available in DO-214AA (SMB) package? A: Yes. All substitute parts listed are available in DO-214AA (SMB) surface mount package, ensuring mechanical and electrical compatibility with the original design.

Q: What compliance certifications apply to all substitute parts? A: All substitute parts are RoHS compliant (ROHS3 or RoHS). All carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The Littelfuse part additionally carries AEC-Q101 automotive qualification.
