P6SMB82C Equivalent & Substitute Parts

Part Overview

The P6SMB82C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This component features a 70.1V reverse standoff voltage with a maximum clamping voltage of 118.65V at peak pulse current. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB82C is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Clamping (Max) @ Ipp: Must remain within acceptable operating margins
• Current - Peak Pulse (10/1000µs): 5.4A
• Package / Case: DO-214AA, SMB (surface mount compatibility)
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Bidirectional Channels: 1

The P6SMB82CA qualifies as a direct substitute based on matching reverse standoff voltage (70.1V), identical peak pulse current rating (5.4A), equivalent power dissipation (600W), compatible SMB package configuration, and overlapping operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB82CA (Eaton - Electronics Division) is the qualified substitute for the obsolete P6SMB82C. Selection is based on the following factors:

• Both components maintain identical reverse standoff voltage (70.1V) and peak pulse current specifications (5.4A)
• The P6SMB82CA is currently in active production status, ensuring procurement availability
• Both parts are RoHS compliant and meet the same environmental and regulatory requirements
• Package and mounting configurations are identical (DO-214AA, SMB surface mount)
• Operating temperature ranges are equivalent (-55°C ~ 150°C)
• The P6SMB82CA clamping voltage (113V) is lower than the original part (118.65V), providing improved transient suppression performance within the same electrical class

Frequently Asked Questions (FAQ)

Q: Can the P6SMB82CA be used as a direct replacement for P6SMB82C in existing designs?

A: Yes. Both components share identical reverse standoff voltage (70.1V), peak pulse current (5.4A), power dissipation (600W), and package configuration (DO-214AA, SMB). The P6SMB82CA is electrically and mechanically compatible for direct substitution.

Q: What is the difference in clamping voltage between these parts?

A: The P6SMB82C has a maximum clamping voltage of 118.65V, while the P6SMB82CA is rated at 113V. The lower clamping voltage of the substitute part provides enhanced transient suppression performance.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The P6SMB82C carries ROHS3 certification, while the P6SMB82CA carries standard RoHS certification. Both meet regulatory requirements for electronic component use.

Q: Is the SMB package configuration identical between both parts?

A: Yes. Both the P6SMB82C and P6SMB82CA use the DO-214AA (SMB) surface mount package, ensuring identical PCB footprint and assembly compatibility.

Q: Why is the P6SMB82C listed as obsolete?

A: The P6SMB82C is no longer in active production by Littelfuse Inc. The P6SMB82CA from Eaton provides equivalent electrical performance and is currently available in production quantities.
