Product details
Overview
P6KE8V2A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 7.02V minimum breakdown voltage (VBR), 8.61V maximum clamping voltage (VC) at 50A peak pulse current, and 12.1V max clamping voltage at rated IPP, housed in a DO-15 package for through-hole mounting in industrial power supplies and automotive body electronics.
For engineers reviewing the P6KE8V2A-T datasheet, P6KE8V2A-T pinout, P6KE8V2A-T application, or P6KE8V2A-T equivalent, this page delivers verified electrical parameters, clamping behavior under 10/1000µs surge, thermal derating curves, DO-15 terminal configuration, and direct alternatives with documented VRWM, VC, and IPP differences - all critical for surge immunity validation and BOM continuity planning.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below 7.02V reverse standoff (VRWM = 7.02V), then avalanches sharply at VBR (7.79V typ.) to limit transients. Its 12.1V clamping voltage at 50A IPP ensures downstream ICs see no more than 12.1V during a 600W, 1ms pulse.
Thermal design relies on its 20°C/W junction-to-case resistance and 75°C/W junction-to-ambient rating; steady-state dissipation is limited to 5.0W at TL = +75°C. The DO-15 package supports 100A non-repetitive forward surge (IFSM) and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000µs waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage (VRWM) | 7.02V (maximum continuous DC or RMS voltage before leakage exceeds 200µA) |
| Breakdown Voltage (VBR) | 7.79V min / 8.61V max @ 10mA (avalanche onset range; determines turn-on threshold precision) |
| Max Clamping Voltage (VC) | 12.1V @ 50A IPP (worst-case rail voltage seen by protected circuit during surge) |
| Peak Pulse Current (IPP) | 50.0A (maximum single-pulse surge current the device can safely clamp) |
| Junction-to-Ambient RθJA | 75°C/W (thermal resistance defining temperature rise per watt at PCB level) |
Pinout & Package
Package: DO-15 molded plastic case with axial leads, UL 94V-0 rated, 0.4g weight, cathode band marking for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; defines current sink direction during clamping |
| Cathode | Protected line input | Connected to the line being protected (e.g., +12V rail); avalanche conduction occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 12V systems without derating |
| Glass-passivated silicon die | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| Fast response time (<1ps) | Clamps transients before sensitive downstream logic or analog circuits experience overvoltage damage |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; suitable for automotive PPAP submissions |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protecting 12V CAN bus power rail from load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VBAT and GND upstream of DC-DC converter input. Use Value: Limits voltage to ≤12.1V during 50A surge, preventing MOSFET gate oxide rupture and regulator latch-up. |

| AC-DC Adapter Secondary Side | Telecom Power Feeding Interface |
Use Scenario: Overvoltage suppression on +5V/3.3V outputs of flyback converters subject to feedback loop failure. IC Role / Device Role / Timing Role: Final-stage clamp after secondary rectifier, before LDO or load. Use Value: 12.1V clamping prevents downstream logic ICs from exceeding absolute maximum ratings during output short-circuit recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A-T | VRWM = 8.0V, VC = 12.7V @ 42.2A, IPP = 42.2A, SMB package | Lower peak current rating; surface-mount only; tighter VRWM tolerance (±5%) | Select for space-constrained PCBs where 42A surge margin suffices and reflow compatibility is required. |
| 1.5KE8.2A | VRWM = 7.02V, VC = 12.2V @ 49.2A, IPP = 49.2A, DO-201 package | Same electrical specs but larger DO-201 case; higher thermal mass; 7.0W steady-state rating | Choose when higher thermal endurance is needed in high-ambient environments (>85°C) or for legacy DO-201 footprint reuse. |
Compared with SMBJ8.0A-T and 1.5KE8.2A, P6KE8V2A-T offers optimal balance of 50A surge capacity, DO-15 through-hole mechanical robustness, and cost-effective replacement for legacy 1N6267-style designs - making it preferred for industrial control panels and automotive harness-mounted protectors where manual assembly and vibration resistance matter.

FAQ
Is P6KE8V2A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE6V8(C)A–P6KE400(C)A family, including P6KE8V2A-T, as stated in DS21502 Rev. 20-4. However, Aetrix Electronics maintains strategic inventory and offers last-time-buy support with full traceability and extended lifecycle coordination for ongoing production programs.
What is the difference between P6KE8V2A-T and P6KE8V2CA-T?
P6KE8V2A-T is unidirectional (cathode-banded), clamping only in reverse bias; P6KE8V2CA-T is bidirectional (no cathode band), providing symmetrical clamping for AC lines or differential signals. Their VRWM, VBR, and VC values are identical, but bidirectional leakage is doubled for VR ≤10V per datasheet Note 5.
Can P6KE8V2A-T replace 1N6267A in existing designs?
Yes - P6KE8V2A-T is a direct functional and mechanical replacement for 1N6267A: both are DO-15 unidirectional 600W TVS diodes with VRWM = 7.0V, VBR ≈ 7.8V, and VC ≈ 12.1V @ 50A. Diodes' datasheet confirms identical electrical specs and package dimensions, enabling drop-in substitution without layout change.
What is the maximum operating temperature for P6KE8V2A-T?
The junction and storage temperature range is –55°C to +175°C. For reliable long-term operation, keep junction temperature below 150°C using the provided derating curves: at 75°C lead temperature, steady-state power must be limited to 5.0W; above that, linear derating applies per Figure 5 in DS21502.
