Product details
Overview
P6KE6V8CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 6.8V reverse standoff voltage (VRWM), 6.45V minimum breakdown voltage (VBR), 10.5V maximum clamping voltage (VC) at 57A peak pulse current, and DO-15 axial package - used in automotive body control modules, industrial PLC I/O protection, and telecom power supply surge suppression.
For engineers reviewing the P6KE6V8CA-T datasheet, P6KE6V8CA-T pinout, P6KE6V8CA-T application, or P6KE6V8CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, 1.0ms 600W pulse handling capability, bidirectional polarity for AC-coupled or floating circuits, and DO-15 lead-form compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS operates as a voltage-clamped crowbar device triggered by transient overvoltage exceeding its breakdown threshold. Its glass-passivated silicon junction enables fast response (<1.0ns) and stable clamping under 8.3ms half-sine surges up to 100A IFSM.
The bidirectional variant (suffix 'C') provides symmetrical clamping for AC signals or ungrounded differential buses, with identical VRWM and VC specifications in both polarities - unlike unidirectional types that require explicit cathode orientation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive waveform - sustains IEEE C62.41 Category A/B surges without failure |
| Reverse Standoff Voltage | 6.8V - maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage |
| Breakdown Voltage | 6.45V min @ 10mA IT - ensures reliable triggering just above normal rail voltage |
| Clamping Voltage | 10.5V max @ 57A IPP - limits transient voltage seen by downstream ICs to safe level during surge |
| Package | DO-15 axial leaded - compatible with manual soldering, wave soldering, and automated through-hole insertion |
| Thermal Resistance | RθJA = 75°C/W - defines derating curve for ambient temperature operation up to +175°C junction |
| Leakage Current | 1000µA max @ 6.8V VR - low enough to avoid loading 5V/3.3V logic rails during normal operation |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), 0.4g weight, 9.5mm lead length for thermal dissipation. Cathode band not marked on bidirectional version per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during negative transients | Enables clamping of negative-going surges relative to reference node |
| Cathode | Current entry point during positive transients | Enables clamping of positive-going surges relative to reference node |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Provides symmetrical surge suppression for AC-coupled interfaces or floating grounds without polarity constraints |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage under thermal cycling and humidity stress |
| 600W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4kV line-to-line, 2kV line-to-earth) surge immunity requirements |
| RoHS-compliant lead finish | Enables compatibility with Pb-free reflow and wave soldering processes per JEDEC J-STD-020 |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects microcontroller GPIOs and CAN transceiver power pins from load dump and alternator ripple in 12V vehicle systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point before ESD diode array. Use Value: Limits transient voltage to ≤10.5V, preventing latch-up or oxide rupture in 5V-tolerant MCU I/O cells during ISO 7637-2 Pulse 5a events. | Use Scenario: Shields 24V digital input optocoupler front-end from field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: First-stage surge absorber upstream of series current-limiting resistor and Zener clamp. Use Value: Absorbs 600W energy within 1ms, reducing stress on downstream 1W Zener and enabling use of lower-cost optocouplers rated only for 12V transients. |
| Telecom Power Supply Output | AC-DC Adapter Secondary Side |
Use Scenario: Safeguards PoE-powered device DC-DC converter inputs against induced lightning surges on Ethernet cables. IC Role / Device Role / Timing Role: Bidirectional clamp across +48V and return, referenced to isolated secondary ground. Use Value: Clamps both positive and negative surges to ≤10.5V, maintaining isolation barrier integrity while protecting synchronous rectifier MOSFET gate drivers. | Use Scenario: Suppresses switching noise and line-induced spikes on 5V/12V outputs of wall-mount adapters. IC Role / Device Role / Timing Role: Final-stage transient filter between output capacitor and USB/DC barrel jack terminals. Use Value: Prevents >10.5V spikes from reaching connected devices, satisfying UL 62368-1 transient immunity requirements for end-user ports. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | Same VRWM and VC, but SMB surface-mount package (vs. DO-15 through-hole); 600W rating retained | Requires PCB redesign for SMT placement; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated assembly is used |
| 1.5KE6.8CA | Same electrical specs but higher 1500W peak power rating; larger DO-201AE package | Overqualified for 600W needs; adds mechanical bulk and cost without functional benefit | Select only if future surge test requirements may exceed 600W or if legacy DO-201AE footprint exists |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6V8CA-T offers optimal balance of proven reliability in through-hole designs, cost efficiency for medium-volume production, and direct drop-in replacement for legacy P6KE-series layouts - making it preferred for industrial control panels and automotive aftermarket ECUs where manual repairability and thermal mass matter.

FAQ
Is P6KE6V8CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE6V8CA-T and marked it as obsolete per DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for last-time buy planning and migration paths to SMBJ6.8CA or SMF6.8CA.
What is the difference between P6KE6V8A-T and P6KE6V8CA-T?
P6KE6V8A-T is unidirectional (cathode-banded), clamping only positive transients relative to ground; P6KE6V8CA-T is bidirectional, clamping both polarities symmetrically. Their VRWM, VBR, and VC values are identical, but the 'C' suffix indicates dual-junction construction enabling AC or floating-rail protection without polarity concerns.
Can P6KE6V8CA-T be used in place of a 5.0V TVS?
No - its 6.8V VRWM exceeds typical 5V system rails; using it risks insufficient clamping margin. For 5V circuits, select P6KE5.0CA-T (VRWM = 5.0V, VC = 9.2V @ 43.5A) or SMF5.0CA (SOD-123, same electrical specs). Exceeding VRWM by >10% may cause excessive leakage or premature conduction.
Does P6KE6V8CA-T meet AEC-Q101 qualification?
No - the P6KE6V8CA-T is not AEC-Q101 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to this standard commercial-grade part. For AEC-Q101 compliance, specify Automotive Qualified variants such as D3V3M1UQ-7.
