P6SMB110C Equivalent & Substitute Parts

Part Overview

The P6SMB110C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 94V reverse standoff voltage and provides 159.6V maximum clamping voltage at 4A peak pulse current in a DO-214AA (SMB) package. The P6SMB110C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB110C is determined by strict equivalence in the following electrical and mechanical parameters:

• Reverse standoff voltage: 94V (all substitutes match)
• Bidirectional channels: 1 (all substitutes match)
• Package type: DO-214AA / SMB (all substitutes match)
• Mounting type: Surface mount (all substitutes match)
• Peak pulse power: 600W (all substitutes match)
• Operating temperature range: -55°C to 150°C minimum (all substitutes meet or exceed)
• Clamping voltage and peak pulse current: Within acceptable tolerance bands for the 94V class

All three substitute parts meet these criteria and are classified as active products, providing viable alternatives to the obsolete P6SMB110C.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are suitable replacements for the obsolete P6SMB110C based on electrical and mechanical equivalence. Selection among the active alternatives should consider:

P6SMB110CA (Eaton): Active product with highest inventory availability (30,100 pcs). Maintains exact electrical specifications of the original part, including 4A peak pulse current. RoHS compliant with REACH unaffected status. Recommended for applications requiring maximum supply chain continuity.

P6SMB110CA-E3/5B (Vishay): Active product with extended operating temperature range (-65°C to 150°C). Offers slightly reduced peak pulse current (3.9A) and lower clamping voltage (152V vs 159.6V), both within acceptable tolerance for the 94V class. ROHS3 compliant with REACH unaffected status. Suitable for temperature-critical applications.

TVP06B111CA-G (Comchip): Active product with peak pulse current of 3.95A and clamping voltage of 152V. ROHS3 compliant with REACH unaffected status. Provides equivalent performance within the 94V TVS diode class specifications.

Frequently Asked Questions (FAQ)

Q: Can P6SMB110CA be used as a direct replacement for P6SMB110C?

A: Yes. Both parts share identical reverse standoff voltage (94V), peak pulse power (600W), package type (DO-214AA/SMB), and operating temperature range (-55°C to 150°C). The P6SMB110CA is an active product from Eaton and maintains the same electrical performance specifications.

Q: What is the difference between the clamping voltages listed for each part?

A: The P6SMB110C specifies 159.6V maximum clamping voltage, while the three substitute parts specify 152V. Both values fall within the acceptable tolerance band for 94V reverse standoff TVS diodes. The lower clamping voltage of the substitutes provides equivalent or improved overvoltage protection performance.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface-mount package, ensuring mechanical and thermal compatibility with existing PCB designs and assembly processes.

Q: Which substitute part has the best temperature performance?

A: The P6SMB110CA-E3/5B from Vishay offers an extended operating temperature range of -65°C to 150°C, compared to -55°C to 150°C for the other parts. This provides additional margin for applications operating in low-temperature environments.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are RoHS compliant. The P6SMB110C, P6SMB110CA-E3/5B, and TVP06B111CA-G are ROHS3 compliant. The P6SMB110CA from Eaton is RoHS compliant. All parts have MSL rating of 1 (Unlimited).

Q: What is the peak pulse current difference between substitutes?

A: The P6SMB110CA maintains 4A peak pulse current, matching the original P6SMB110C. The P6SMB110CA-E3/5B and TVP06B111CA-G specify 3.9A and 3.95A respectively. These minor reductions remain within acceptable performance parameters for the 94V TVS diode class.
