Product details
Overview
P6KE6.8A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection at DC power rails and signal lines. It features a nominal breakdown voltage of 6.8V, clamps transients to ≤10.5V at 60A peak surge current, and exhibits <1μA reverse leakage at 5.8V standoff voltage - enabling robust ESD and lightning surge protection in automotive body electronics and industrial control I/O circuits.
For engineers reviewing the P6KE6.8A datasheet, P6KE6.8A pinout, P6KE6.8A application, or P6KE6.8A equivalent, key selection criteria include its DO-15 package compatibility, 600W 10/1000μs surge rating, low 10.5V clamping voltage at rated IPP, and AEC-Q101 qualification for automotive-grade reliability - all critical for front-end protection in 5V/12V embedded systems.
Technical Context
The P6KE6.8A operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its minimum breakdown threshold of 6.46V at 10mA test current. Its low dynamic impedance ensures rapid clamping response (<1.0ps rise time from 0V to VBR), minimizing voltage overshoot during fast transients such as EFT or ISO 7637-2 pulses.
Thermal performance is defined by a 175°C maximum junction temperature and derating curves supporting operation up to 75°C ambient with 5W steady-state dissipation on specified copper pads. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards, confirming suitability for high-reliability soldered assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.46V / 7.14V at 10mA - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 5.80V - maximum continuous reverse operating voltage before leakage exceeds 1μA |
| VC @ IPP | 10.5V at 60A - peak clamped voltage during 600W 10/1000μs surge, limiting downstream stress |
| PPK | 600W - non-repetitive surge power handling per standard 10/1000μs waveform |
| IR @ VWM | <1μA - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| TJ max | 175°C - enables operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Dimensions conform to JEDEC DO-15 outline; terminals are pure tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or lower-potential rail in unidirectional configuration |

Key Features
| Feature | Design Value |
|---|---|
| 600W surge capability | Withstands 10/1000μs transients without degradation - sufficient for ISO 16750-2 Pulse 5a/b and IEC 61000-4-5 Level 3 |

Applications
| Automotive Body Electronics | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers and LED driver ICs from load dump and alternator ripple in door modules and lighting systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12V supply rail upstream of LDO regulators and communication ICs. Use Value: Prevents latch-up and permanent damage during ISO 16750-2 Pulse 5a (12V system, +75V/100ms) events. |

IC Role / Device Role / Timing Role: Fast-acting shunt protector placed directly at connector entry point before signal conditioning circuitry. Use Value: Limits transient voltage to <10.5V, preserving ADC reference stability and preventing op-amp saturation. |
| Consumer Power Adapter Input | USB-C Port Protection |
Use Scenario: Secondary-side surge suppression on 5V DC output rails of wall adapters subjected to mains-borne transients. IC Role / Device Role / Timing Role: Standoff-rated TVS across VBUS and GND to absorb residual surges escaping primary-side MOVs. Use Value: Maintains 5.8V working voltage margin while clamping to 10.5V - compatible with USB PD 2.0 specifications. |
Use Scenario: Bidirectional-capable variant not applicable; P6KE6.8A used in unidirectional 5V rail protection for legacy USB-A ports or VBUS filtering in USB-C receptacles. IC Role / Device Role / Timing Role: Low-leakage clamping element on VBUS line to prevent overvoltage damage to USB controller and power delivery ICs. Use Value: Sub-1μA leakage at 5.8V avoids standby current penalties; 10.5V clamping prevents USB 2.0 PHY reset thresholds from being exceeded. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | Same 6.8V nominal, 10.5V clamping, but SMB package (surface-mount); 600W rating identical | Requires PCB rework for SMT assembly; better thermal performance in compact layouts | Select when automated assembly and space constraints favor SMD over through-hole DO-15 |
| 1.5KE6.8A | Same DO-15 package and 6.8V rating, but 1500W peak power (10/1000μs); higher VC = 11.2V | Higher clamping voltage reduces protection margin for 5V logic; suited for higher-energy threats | Choose only if system-level testing confirms 11.2V clamping is acceptable and 1500W surge immunity is required |
Compared with SMBJ6.8A and 1.5KE6.8A, the P6KE6.8A offers optimal balance of through-hole manufacturability, 10.5V clamping headroom for 5V systems, and AEC-Q101 qualification - making it preferred for automotive and industrial designs where reliability and legacy assembly compatibility are prioritized.

FAQ
What is the maximum clamping voltage of the P6KE6.8A under rated surge conditions?
The P6KE6.8A has a maximum clamping voltage (VC) of 10.5V at 60A peak pulse current (IPP), measured using the standardized 10/1000μs waveform. This value ensures that protected 5V logic circuits remain within safe operating limits during transient events, and is confirmed in the Electrical Specifications table on page 2 of the official TSC P2203 datasheet.
Is the P6KE6.8A suitable for automotive applications?
Yes, the P6KE6.8A is AEC-Q101 qualified (as indicated by the "H" suffix option in ordering codes), making it suitable for automotive applications including body control modules, lighting drivers, and infotainment power rails. Its 175°C junction temperature rating and robust surge performance align with ISO 16750-2 and ISO 7637-2 requirements for vehicle electrical systems.
What does the "A" suffix signify in P6KE6.8A compared to P6KE6.8?
The "A" suffix in P6KE6.8A denotes tighter parameter tolerances: VBR is specified as 6.46–7.14V (vs. 6.12–7.48V for P6KE6.8), VWM is 5.80V (vs. 5.50V), and VC is 10.5V (vs. 10.8V). These tighter specs improve design margin consistency in precision 5V protection applications where clamping predictability is critical.
Can the P6KE6.8A be used in bidirectional configurations?
No - the P6KE6.8A is a unidirectional TVS diode, intended for DC rail protection with defined anode/cathode polarity. For bidirectional protection (e.g., AC lines or data buses), TSC offers the P6KE6.8CA variant. Using P6KE6.8A in reverse-biased mode beyond its VWM risks premature conduction and unreliable clamping behavior.
What is the packaging format for standard orders of P6KE6.8A?
Standard packaging for P6KE6.8A is 3,500 units per tape-and-reel (ordering code P6KE6.8AH), compliant with EIA-481 standards. Ammo box packaging (1,500 units) is also available under code P6KE6.8A0G. Both formats use DO-204AC (DO-15) axial leads with cathode band marking and RoHS-compliant green molding compound.
