P6SMB16C Equivalent & Substitute Parts

Part Overview

The P6SMB16C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection in surface mount applications. This component features a 13.6V reverse standoff voltage with a 23.63V maximum clamping voltage and 27.1A peak pulse current capability in a DO-214AA (SMB) package. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB16C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Clamping (Max) @ Ipp: Maximum 23.63V
• Current - Peak Pulse (10/1000µs): Minimum 26.67A
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C minimum to 150°C maximum
• RoHS Compliance: ROHS3 Compliant

The identified substitute parts maintain electrical compatibility within these parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain compliance with ROHS3 requirements and are actively manufactured, addressing the obsolescence status of the P6SMB16C.

P6SMB16CA (Meritek): This part meets all critical electrical parameters with a clamping voltage of 22.5V, which is lower than the original 23.63V specification. Peak pulse current is 26.67A, marginally below the original 27.1A. Operating temperature range matches the original specification at -55°C to 150°C. This part is available in Tape & Reel packaging with 68,100 units in stock.

SMBJP6KE16CA-TP (Micro Commercial Co): This part matches the original peak pulse current specification at 27.1A and maintains the same clamping voltage of 22.5V as the Meritek alternative. The operating temperature range extends to 175°C, providing additional thermal margin beyond the original -55°C to 150°C specification. This part is supplied in Tape & Reel packaging with 1,025 units in stock.

Both alternatives are electrically compatible within the allowed parameter tolerances for this TVS diode category and maintain identical package and mounting specifications.

Frequently Asked Questions (FAQ)

Q: Why is the P6SMB16C listed as obsolete? A: The P6SMB16C is no longer in active production by Littelfuse. Substitute parts from active manufacturers provide equivalent functionality and ensure long-term design support.

Q: Can P6SMB16CA and SMBJP6KE16CA-TP be used interchangeably with P6SMB16C? A: Both substitute parts maintain the same reverse standoff voltage (13.6V), package type (DO-214AA SMB), and mounting configuration. The clamping voltage and peak pulse current specifications fall within acceptable tolerances for TVS diode substitution in this voltage class.

Q: What is the difference between the two substitute options? A: The primary differences are manufacturer, peak pulse current specification (26.67A for Meritek versus 27.1A for Micro Commercial Co), and operating temperature range (150°C maximum for Meritek versus 175°C for Micro Commercial Co). Both meet the electrical requirements of the original part.

Q: Does packaging affect substitution compatibility? A: Both substitute parts use the same DO-214AA (SMB) surface mount package as the original P6SMB16C. Tape & Reel packaging is a supply format and does not affect electrical or mechanical compatibility on the PCB.

Q: Are all three parts RoHS compliant? A: Yes. The P6SMB16C, P6SMB16CA, and SMBJP6KE16CA-TP are all ROHS3 compliant.
