P6KE8V2A-T Equivalent & Substitute Parts
Part Overview
The P6KE8V2A-T is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 7.02V reverse standoff voltage with 12.1V maximum clamping voltage at 50A peak pulse current. Designed for general-purpose transient protection in through-hole DO-15 packaging, this component is currently obsolete. Identifying equivalent and substitute parts is essential for ongoing design support, production continuity, and system maintenance where this device is specified.

Substitute Part Grouping Explanation
Substitution of the P6KE8V2A-T is determined by strict equivalence across the following critical parameters:
- Voltage - Reverse Standoff (Typ): 7.02V
- Voltage - Breakdown (Min): 7.79V
- Voltage - Clamping (Max) @ Ipp: 12.1V
- Current - Peak Pulse (10/1000µs): 50A minimum
- Power - Peak Pulse: 600W
- Operating Temperature Range: -55°C to 175°C (TJ)
- Mounting Type: Through Hole
- Package / Case: DO-204AC, DO-15, or Axial
- Type: Zener
- Unidirectional Channels: 1
Substitute parts are grouped into two categories:
Direct Electrical Equivalents (DO-15 Package): Parts maintaining identical electrical specifications and DO-15 through-hole packaging with active product status.
Functional Equivalents with Package Variation (Axial Package): Parts meeting all electrical specifications but supplied in alternative through-hole axial packaging.
Lower-Power Alternative: Parts with reduced peak pulse current (34A) and power rating (400W), suitable only where transient energy levels are lower than the original specification.

Engineering Selection Recommendations
Primary Substitutes (Full Electrical Equivalence, DO-15 Package):
P6KE8V2A-B, P6KE8.2A-AP, P6KE8.2A-BP, and P6KE8.2A-TP are direct replacements for the obsolete P6KE8V2A-T. All maintain identical voltage ratings, peak pulse current of 50A, 600W power dissipation, and -55°C to 175°C operating temperature range in DO-15 through-hole packaging. These parts carry active product status and ROHS3 compliance. Selection among these options depends on packaging format availability (bulk, cut tape, or tape & reel) and supplier inventory requirements.
Secondary Substitute (Equivalent Electrical Performance, Axial Package):
P6KE8.2AE3/TR13 from Microsemi Corporation meets all electrical specifications with 50A peak pulse current and 600W power dissipation. The operating temperature range is -65°C to 150°C, which is narrower at the upper limit (150°C vs. 175°C). This part is supplied in through-hole axial packaging rather than DO-15. Use this substitute only where axial package form factor is acceptable and the maximum junction temperature of 150°C is compatible with the application.
Alternative with Reduced Power Rating:
P4KE8.2A from Taiwan Semiconductor Corporation provides identical voltage characteristics but with reduced peak pulse current (34A) and power dissipation (400W). This part is packaged in DO-204AL (DO-41) axial format. Use only in applications where transient energy levels are confirmed to be below 400W and peak pulse current does not exceed 34A.
Compliance and Availability:
All active substitutes carry ROHS3 compliance and REACH unaffected status. Inventory availability ranges from 612 to 36,160 pieces across substitute options, supporting both prototype and production-volume requirements.
Frequently Asked Questions (FAQ)
Q: Can P6KE8.2A from Taiwan Semiconductor Corporation replace P6KE8V2A-T directly?
A: Yes. P6KE8.2A maintains identical voltage ratings (7.02V standoff, 12.1V clamping) and power specifications (600W, 50A peak pulse). Both are supplied in DO-15 through-hole packaging. The 52A peak pulse rating of the P6KE8.2A exceeds the 50A requirement, providing additional margin. Operating temperature range matches at -55°C to 175°C.
Q: What is the difference between P6KE8.2A-AP, P6KE8.2A-BP, and P6KE8.2A-TP?
A: These three Micro Commercial Co variants are electrically identical. The suffix indicates packaging format: -AP is bulk, -BP is bulk, and -TP is cut tape (CT). All three maintain the same electrical specifications and DO-15 package. Selection depends on procurement and assembly requirements.
Q: Can I use P6KE8.2AE3/TR13 in place of P6KE8V2A-T?
A: P6KE8.2AE3/TR13 is electrically equivalent but supplied in through-hole axial packaging instead of DO-15. The operating temperature range is -65°C to 150°C, which is narrower at the upper limit. Use this substitute only if axial package form factor is acceptable and the application does not require operation above 150°C junction temperature.
Q: Is P4KE8.2A a suitable replacement?
A: P4KE8.2A is not a direct replacement. While voltage ratings are identical, peak pulse current is reduced to 34A and power dissipation to 400W. Use P4KE8.2A only in applications where transient energy is confirmed to be below these reduced ratings. Additionally, this part is supplied in DO-204AL (DO-41) axial packaging, not DO-15.
Q: What compliance certifications apply to substitute parts?
A: All active substitute parts carry ROHS3 compliance. REACH status is unaffected for all substitutes. Moisture sensitivity level is 1 (unlimited) for parts where specified. Verify specific certifications with the selected manufacturer if additional compliance documentation is required.
Q: Why is the original P6KE8V2A-T obsolete?
A: The P6KE8V2A-T from Diodes Incorporated is marked obsolete. Multiple active alternatives with identical electrical specifications are available from other manufacturers, ensuring design continuity and production support.
