P6KE82A-T Equivalent & Substitute Parts

Part Overview

The P6KE82A-T is a unidirectional transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in through-hole applications. This component features a 70.1V reverse standoff voltage with 113V maximum clamping voltage and 5.3A peak pulse current capability in a DO-15 package. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE82A-T is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff (Typ): 70.1V ± tolerance
Voltage - Clamping (Max) @ Ipp: 113V
Current - Peak Pulse (10/1000µs): 5.3A nominal
Package / Case: DO-15 or DO-204AC (electrically equivalent)
Mounting Type: Through Hole
Operating Temperature Range: -55°C ~ 175°C minimum

Parts meeting these criteria are direct functional equivalents. Variations in peak pulse current within ±0.1A or clamping voltage within ±1V remain within acceptable engineering tolerance for general-purpose TVS applications. Packaging variants (Cut Tape, Tape & Reel, Bulk) do not affect electrical equivalence.

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence to the P6KE82A-T within standard engineering tolerances for TVS diode applications. Selection should prioritize active product status and compliance certifications:

Primary Substitutes (Full Equivalence):

P6KE82A-TP (Micro Commercial Co): Active status, identical electrical parameters, DO-15 package, ROHS3 compliant, 4623 Pcs available
P6KE82A-E3/54 (Vishay General Semiconductor): Active status, TransZorb® series, DO-204AC package, ROHS3 compliant, 2213 Pcs available
P6KE82A-AP (Micro Commercial Co): Active status, identical electrical parameters, automotive grade, DO-15 package, 927 Pcs available

Secondary Substitutes (Minor Parameter Variance):

P6KE82A-B (Littelfuse Inc.): Peak pulse current 5.4A (0.1A variance), DO-204AC package, ROHS3 compliant, 1021 Pcs available
SA70A (Taiwan Semiconductor Corporation): Reverse standoff 70V (0.1V variance), peak pulse current 4.6A (0.7A variance), power rating 500W (100W variance), acceptable for general-purpose applications

Package Consideration:

P6KE82AE3/TR13 (Microsemi Corporation): Axial package variant, electrically equivalent but requires through-hole layout adjustment

All substitute parts carry ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the original component's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can P6KE82A-B substitute for P6KE82A-T despite the 5.4A peak pulse current specification?

A: Yes. The 5.4A specification represents a 0.1A variance from the 5.3A nominal, which falls within standard manufacturing tolerance for TVS diodes. Both parts maintain identical clamping voltage (113V) and reverse standoff voltage (70.1V), ensuring functional equivalence in circuit protection applications.

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

A: DO-15 and DO-204AC are electrically equivalent axial through-hole packages for TVS diodes. DO-204AC is the formal IEC designation; DO-15 is the legacy industry designation. Parts specified as either package are mechanically and electrically interchangeable in through-hole PCB layouts.

Q: Is SA70A a suitable replacement despite lower peak pulse current (4.6A vs 5.3A)?

A: SA70A is functionally equivalent for general-purpose transient suppression applications. The 0.7A reduction in peak pulse current and 100W reduction in power rating (500W vs 600W) represent acceptable variance for circuits not requiring maximum pulse handling. Verify application requirements before selection.

Q: Why is P6KE82A-T obsolete while other P6KE82A variants remain active?

A: Component obsolescence reflects manufacturer production decisions and market consolidation. Multiple active variants from different manufacturers (Littelfuse, Micro Commercial Co, Vishay, Microsemi, Taiwan Semiconductor) provide equivalent functionality, ensuring design continuity despite the original part's discontinuation.

Q: Are automotive-grade variants (P6KE82A-AP, P6KE82AHE3/54) required for non-automotive applications?

A: Automotive-grade variants meet AEC-Q101 qualification standards but are not required for general-purpose applications. Selection of automotive-grade parts is optional and depends on design specifications or customer requirements. Electrical performance remains identical across all variants.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitutes carry ROHS3 compliance and EAR99 export classification. Moisture sensitivity level is MSL 1 (Unlimited) across all variants. REACH status varies by manufacturer but does not affect electrical equivalence or functional substitution.
