Product details
Overview
P6KE6.8C from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for clamping high-energy ESD and lightning-induced surges in power and signal lines. It features a nominal breakdown voltage of 6.8V, maximum clamping voltage of 10.8V at 58A peak surge current, and operates within -55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial sensor interfaces.
For engineers reviewing the P6KE6.8C datasheet, P6KE6.8C pinout, P6KE6.8C application, or P6KE6.8C equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, 10.8V clamping performance under 10/1000μs waveform, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE6.8C uses a planar passivated silicon junction structure optimized for fast transient response (<5.0ns for bidirectional operation) and low dynamic impedance. Its unidirectional counterpart (P6KE6.8) shares identical VBR min/max (6.12–7.48V) and thermal limits but differs in polarity marking and leakage behavior above VWM.
Designed per ANSI/IEEE C62.35 standards, it delivers 600W non-repetitive peak pulse power at 10/1000μs, with clamping voltage tightly specified at 10.8V @ IPP = 58A. The device exhibits a temperature coefficient of VBR at 0.057%/°C and maintains <1μA reverse leakage at 5.5V stand-off voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.12V / 7.48V - ensures reliable conduction onset across production lot and temperature range |
| VWM | 5.5V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPP | 10.8V @ 58A - peak clamped voltage during 10/1000μs surge, defining protected circuit's worst-case overvoltage |
| PPK | 600W - surge energy handling capacity per single 10/1000μs event without failure |
| TJ max | +175°C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.400g mass and UL 94V-0 molding compound |
| Configuration | Bidirectional - symmetrical clamping in both polarities, eliminating need for polarity-aware PCB layout |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking omitted for bidirectional variants; terminals are non-polarized and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both leads serve identical bidirectional clamping function; no polarity dependency in circuit placement |
| Leads (tin-plated) | PCB interface & thermal path | Pure tin plating ensures J-STD-002 solderability; lead length affects power derating per JEDEC standards |
Key Features
| Feature | Design Value |

| Clamping voltage ≤10.8V @ 58A | Enables robust protection of 5V logic rails and USB/UART interfaces without overstressing downstream ICs |
| Response time <5.0ns (bidirectional) | Prevents sub-microsecond EFT transients from propagating into sensitive analog or digital circuitry |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and global environmental directives for industrial and automotive supply chains |
| UL recognition (E-326243) | Supports end-equipment safety certification without additional component-level testing burden |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | Same 6.8V nominal, 600W rating, but SMB package (surface-mount); lower clamping voltage (11.2V) | Requires PCB rework for SMT assembly; better thermal performance in high-density layouts | Select when board space is constrained and reflow compatibility is required |
| 1.5KE6.8C | Same DO-15 package and bidirectional function, but 1500W rating; higher VC (12.6V @ 118A) | Over-specified for 600W use cases; larger junction area increases capacitance and cost | Select only if system-level surge testing exceeds IEC 61000-4-5 Level 4 requirements |
Compared with P6KE6.8C, SMBJ6.8CA offers superior mounting flexibility but lacks AEC-Q101 validation, while 1.5KE6.8C provides higher surge margin at the expense of clamping precision and cost efficiency for standard 600W protection needs.

FAQ
What does the 'C' suffix indicate in P6KE6.8C?
The 'C' suffix in P6KE6.8C denotes bidirectional configuration, meaning the device clamps transients equally in both polarities without internal polarity marking. This distinguishes it from unidirectional variants like P6KE6.8, which feature a cathode band and conduct only in reverse bias. P6KE6.8C is functionally symmetric and ideal for AC-coupled or differential signal protection where polarity cannot be guaranteed.
Is P6KE6.8C AEC-Q101 qualified?
Yes, P6KE6.8C is AEC-Q101 qualified per the manufacturer's ordering code documentation - specifically indicated by the 'H' suffix variant (e.g., P6KE6.8CH), though base P6KE6.8C shares the same die and qualification scope. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, confirming suitability for automotive powertrain and chassis applications.
What is the maximum clamping voltage of P6KE6.8C and under what test condition?
The maximum clamping voltage of P6KE6.8C is 10.8V, measured at a peak pulse current (IPP) of 58A using the standardized 10/1000μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage seen across the device during worst-case transient events - critical for verifying safe operation of downstream 5V logic components.
Can P6KE6.8C replace P6KE6.8A in a design?
No, P6KE6.8C cannot directly replace P6KE6.8A because they differ fundamentally in configuration: P6KE6.8C is bidirectional, while P6KE6.8A is unidirectional with tighter VBR tolerance (6.46–7.14V vs. 6.12–7.48V). Substituting P6KE6.8C may cause unintended conduction in forward-biased conditions. Always verify polarity requirements and clamping symmetry before interchanging P6KE6.8C and P6KE6.8A in an existing design.
What packaging options are available for P6KE6.8C?
P6KE6.8C is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 pieces per tape-and-reel (ordering code P6KE6.8CH) and 1,500 pieces per ammo box (ordering code P6KE6.8CHA0G). Both variants maintain identical electrical and thermal specifications; the choice depends on assembly method - reel for automated pick-and-place, ammo box for manual or semi-automated insertion.
