Engineering Selection Recommendations

All identified substitute parts maintain active production status and ROHS3 compliance, ensuring regulatory alignment with the original P6KE82A-B specification. Selection among equivalent parts should be based on:

Inventory Availability: Fairchild Semiconductor P6KE82A offers the highest stock level at 7200 units, followed by Micro Commercial Co P6KE82A-TP at 4623 units and Littelfuse TP6KE82A at 3824 units.

Automotive Grade Qualification: The Littelfuse TP6KE82A carries AEC-Q101 automotive qualification and is designated as automotive grade, making it suitable for applications requiring automotive-level reliability standards.

Packaging Variants: Vishay P6KE82A-E3/54 and Littelfuse TP6KE82A are supplied in DO-204AC packaging with cut tape (CT) format, while Micro Commercial Co P6KE82A-TP is supplied in DO-15 packaging with cut tape format. The original P6KE82A-B does not specify packaging format.

Peak Pulse Current: Littelfuse TP6KE82A specifies 5.4A peak pulse current, marginally exceeding the 5.3A specification of other equivalents, providing additional transient protection margin.

All parts are REACH unaffected and carry EAR99 export classification with identical HTSUS coding (8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can P6KE82A-B be directly replaced with P6KE82A from Fairchild Semiconductor?

A: Yes. Both parts share identical electrical specifications (70.1V standoff, 113V clamping, 5.3A peak pulse, 600W power rating) and through-hole mounting configuration. The Fairchild part is a direct functional equivalent with higher inventory availability.

Q: What is the difference between DO-15 and DO-204AC packaging?

A: DO-15 and DO-204AC are equivalent designations for the same axial through-hole package used in TVS diodes. Both refer to a two-lead cylindrical component with identical physical dimensions and pin spacing. Parts specified as DO-204AC (DO-15) or DO-15 are mechanically and electrically interchangeable.

Q: Is the Littelfuse TP6KE82A suitable for automotive applications?

A: Yes. The Littelfuse TP6KE82A carries AEC-Q101 qualification and automotive grade designation, making it appropriate for automotive circuit protection applications. Other substitutes are not specified with automotive qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes (P6KE82A from Fairchild, P6KE82A-E3/54 from Vishay, P6KE82A-TP from Micro Commercial Co, and TP6KE82A from Littelfuse) are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: What is the operating temperature range for these TVS diodes?

A: All parts operate across -55°C to 175°C junction temperature range, supporting applications in industrial, commercial, and automotive environments with wide thermal requirements.

Q: Can I mix manufacturers in the same circuit board assembly?

A: Yes. All substitute parts maintain identical electrical specifications and through-hole mounting compatibility, allowing mixed-manufacturer sourcing within the same design without circuit performance impact.
