P6SMB130 Equivalent & Substitute Parts

Part Overview

The P6SMB130 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 111V reverse standoff voltage with a 187.95V maximum clamping voltage at peak pulse current of 3.4A, packaged in the DO-214AA (SMB) surface mount configuration. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this voltage protection specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB130 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Reverse standoff voltage: 111V (±tolerance acceptable within standard TVS specifications)
• Peak pulse current capability: 3.4A minimum
• Maximum clamping voltage: 179V to 187.95V range
• Package type: DO-214AA (SMB) surface mount configuration
• Unidirectional topology: Single channel Zener diode

Secondary Compatibility Factors:

• Operating temperature range: -55°C to -65°C minimum; 150°C maximum
• Power dissipation: 600W peak pulse rating
• RoHS and REACH compliance status
• Moisture sensitivity level: MSL 1 (Unlimited)

Substitute parts must maintain electrical equivalence within the specified voltage and current parameters while preserving mechanical compatibility with the original DO-214AA footprint. Variations in clamping voltage within the 179V to 187.95V range are acceptable as they remain within the functional protection envelope for the intended application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

P6SMB130A (Eaton - Electronics Division) and P6SMB130A-E3/52 (Vishay General Semiconductor) are the preferred direct substitutes. Both maintain the 111V reverse standoff voltage specification, 3.4A peak pulse current, and 179V clamping voltage. These parts are in active production status with ROHS3 compliance and MSL 1 moisture sensitivity rating. Vishay's variant offers extended operating temperature range (-65°C minimum) compared to the original specification.

Secondary Substitutes (Functional Equivalence):

SMBJP6KE130A-TP (Micro Commercial Co) and TVP06B131A-G (Comchip Technology) provide functional equivalence with 111V standoff voltage and comparable clamping characteristics. Both are active production parts with adequate current handling (3.35A to 3.4A). These options are suitable where primary substitutes are unavailable.

Limited Compatibility Substitute:

SMBJ100E3/TR13 (Microchip Technology) operates at 100V reverse standoff voltage, representing a 11V reduction from the original specification. This part is suitable only for applications where the lower standoff voltage does not compromise circuit protection requirements. Use is conditional on circuit design review.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings consistent with the original part. Eaton and Micro Commercial Co variants do not specify explicit RoHS status but are functionally equivalent. Vishay and Comchip variants provide documented REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can I use SMBJ100E3/TR13 as a direct replacement for P6SMB130?

A: SMBJ100E3/TR13 operates at 100V reverse standoff voltage compared to the P6SMB130's 111V specification. This 11V difference may affect circuit protection margins. Use only after confirming that the lower standoff voltage is acceptable for your specific application requirements.

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

A: Both parts share identical electrical specifications (111V standoff, 3.4A peak pulse, 179V clamping). The primary difference is manufacturer: P6SMB130A is supplied by Eaton, while P6SMB130A-E3/52 is supplied by Vishay. Vishay's variant offers an extended minimum operating temperature of -65°C versus -55°C for Eaton's version.

Q: Are all substitute parts in the same DO-214AA package?

A: Yes. All listed substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility with the original P6SMB130 design.

Q: What is the significance of the clamping voltage difference between 187.95V and 179V?

A: The original P6SMB130 specifies a maximum clamping voltage of 187.95V, while most active substitutes clamp at 179V. This 8.95V difference represents improved clamping performance in the substitute parts. Both values remain within acceptable protection parameters for general-purpose transient suppression applications.

Q: Which substitute offers the best temperature performance?

A: P6SMB130A-E3/52 (Vishay) and SMBJ100E3/TR13 (Microchip) both support -65°C to 150°C operating range, extending the minimum temperature specification by 10°C compared to the original -55°C to 150°C rating.

Q: Are there any compliance differences between substitutes?

A: All substitutes maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings. Vishay and Comchip variants provide explicit REACH compliance documentation. Eaton and Micro Commercial Co variants do not specify REACH status but are functionally equivalent for general-purpose applications.
