Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMBJ110C is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reverse standoff voltage: 94V (nominal)
• Breakdown voltage range: 99.45V minimum
• Clamping voltage: maximum 159.6V @ Ipp
• Peak pulse current: 4A nominal
• Peak pulse power: 600W
• Bidirectional operation: single channel
• Operating temperature range: -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type: DO-214AA (SMB)
• Mounting: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Both substitute parts maintain these core parameters within acceptable engineering tolerances, ensuring functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

P6SMB110CA (Eaton - Electronics Division): This substitute maintains identical reverse standoff voltage (94V) and peak pulse current (4A) specifications. The clamping voltage is reduced to 152V, representing improved performance margin. Product status is active with RoHS compliance certification, ensuring long-term availability and regulatory alignment. Packaging is specified as Tape & Reel (TR), suitable for automated assembly processes.

TVP06B111CA-G (Comchip Technology): This substitute maintains the 94V reverse standoff voltage with peak pulse current of 3.95A, functionally equivalent to the 4A specification. Clamping voltage is 152V, consistent with the Eaton alternative. Product status is active with ROHS3 compliance and REACH unaffected designation. Packaging is specified as Tape & Reel (TR). Inventory availability is lower than the Eaton option.

Both substitutes are suitable for applications requiring the electrical and thermal characteristics of the P6SMBJ110C. Selection between alternatives should be based on procurement availability, packaging requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can P6SMB110CA and TVP06B111CA-G be used interchangeably with P6SMBJ110C? A: Both substitutes maintain the critical electrical parameters: 94V reverse standoff voltage, 600W peak pulse power, and DO-214AA (SMB) surface-mount package. The clamping voltage is lower (152V vs. 159.6V), which represents improved protection performance. Peak pulse current is 4A (P6SMB110CA) or 3.95A (TVP06B111CA-G), both functionally equivalent to the original 4A specification.

Q: What is the primary reason for substitution? A: The P6SMBJ110C is classified as obsolete. The substitute parts P6SMB110CA and TVP06B111CA-G are active products with confirmed availability, ensuring design continuity and procurement reliability.

Q: Are there package compatibility concerns? A: All three parts use the DO-214AA (SMB) surface-mount package. PCB footprints and assembly processes are identical. Both substitutes are available in Tape & Reel (TR) packaging, standard for automated manufacturing.

Q: How do the clamping voltages compare? A: The P6SMBJ110C specifies 159.6V maximum clamping voltage. Both substitutes specify 152V maximum clamping voltage. The lower clamping voltage in substitutes provides tighter voltage regulation and improved transient suppression performance.

Q: Are there compliance differences? A: The P6SMBJ110C is ROHS3 compliant. P6SMB110CA is RoHS compliant. TVP06B111CA-G is ROHS3 compliant with REACH unaffected status. All three meet environmental and regulatory requirements for industrial applications.

Q: What is the operating temperature range? A: All three parts operate across -55°C to 150°C junction temperature, ensuring performance consistency across industrial and commercial temperature environments.
