P6SMBJ11 Equivalent & Substitute Parts

Part Overview

The P6SMBJ11 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 9.4V reverse standoff voltage and 600W peak pulse power rating in a DO-214AA (SMB) package. The P6SMBJ11 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage clamping, peak pulse current, and thermal operating ranges while supporting the same surface-mount package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMBJ11 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 9.4V (exact match required)
• Current - Peak Pulse (10/1000µs): 39.1A (exact match required)
• Power - Peak Pulse: 600W (exact match required)
• Unidirectional Channels: 1 (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variations:

• Voltage - Clamping (Max) @ Ipp: Substitute parts may vary within the range of 15.6V to 16.38V, provided the clamping voltage does not exceed the maximum specified for the application circuit
• Voltage - Breakdown (Min): Substitute parts may vary from 9.95V to 10.5V, maintaining the 9.4V standoff specification
• Operating Temperature Range: Substitute parts may extend the upper temperature limit beyond 150°C, provided the minimum remains at -55°C or lower
• Product Status: Active substitute parts are preferred over obsolete originals for long-term availability

Two substitute parts meet these criteria: SMBJP6KE11A-TP (Micro Commercial Co) and P6SMB11A (Eaton - Electronics Division).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as Active products, ensuring long-term availability and supply chain continuity compared to the obsolete P6SMBJ11. Both SMBJP6KE11A-TP and P6SMB11A maintain full electrical equivalence across all critical parameters: 9.4V reverse standoff voltage, 39.1A peak pulse current, and 600W peak pulse power.

SMBJP6KE11A-TP offers an extended operating temperature range to 175°C and is supplied in Tape & Reel packaging, suitable for high-volume automated assembly. P6SMB11A is recommended by the original manufacturer (Eaton - Electronics Division) and maintains the same -55 to 150°C operating range as the original P6SMBJ11, with RoHS compliance certification.

Both parts are ECCN EAR99 classified and carry HTSUS code 8541.10.0080, matching the regulatory profile of the original component. Selection between the two substitutes should be based on packaging requirements (Tape & Reel vs. standard SMB), temperature operating envelope, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can SMBJP6KE11A-TP and P6SMB11A be used interchangeably with P6SMBJ11?

A: Yes. Both substitute parts maintain the critical electrical parameters: 9.4V reverse standoff voltage, 39.1A peak pulse current, 600W peak pulse power, and identical DO-214AA (SMB) surface-mount package configuration. The lower clamping voltage (15.6V vs. 16.38V) in both substitutes provides improved protection margins in most applications.

Q: What is the difference between the two substitute parts?

A: SMBJP6KE11A-TP extends the operating temperature range to 175°C and is supplied in Tape & Reel packaging for automated assembly. P6SMB11A maintains the original -55 to 150°C temperature range and is available in standard SMB packaging. Both are electrically equivalent.

Q: Are there any compliance or certification differences?

A: SMBJP6KE11A-TP carries ROHS3 compliance and REACH Unaffected status. P6SMB11A carries RoHS compliance. Both meet ECCN EAR99 and HTSUS 8541.10.0080 classifications. Verify specific compliance requirements for your application region.

Q: Does the lower clamping voltage in the substitutes affect circuit performance?

A: The substitute parts clamp at 15.6V maximum versus 16.38V for the original P6SMBJ11. This lower clamping voltage provides tighter voltage regulation and is compatible with circuits designed for the original part, as it represents improved overvoltage suppression.

Q: What packaging options are available?

A: SMBJP6KE11A-TP is supplied in Tape & Reel (TR) format for high-volume production. P6SMB11A is available in standard SMB packaging. Both use the DO-214AA surface-mount package footprint.
