Product details
Overview
P6KE6.8CA A0G from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for clamping high-energy ESD and surge transients across 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 stand-off voltage of 5.5V - enabling robust protection of 5V logic interfaces, USB ports, and automotive sensor inputs without false triggering.
For engineers reviewing the P6KE6.8CA A0G datasheet, P6KE6.8CA A0G pinout, P6KE6.8CA A0G application, or P6KE6.8CA A0G equivalent, key selection criteria include bidirectional clamping symmetry, low dynamic impedance (<0.2Ω typical), sub-5ns response time, and DO-204AC (DO-15) through-hole compatibility with legacy PCB layouts.
Technical Context
The P6KE6.8CA A0G implements a planar junction silicon avalanche structure optimized for fast transient suppression in both polarities. Its bidirectional configuration ensures identical VBR min/max (6.12–7.48V) and VC (10.8V @ 58A) in forward and reverse directions, eliminating polarity dependency during system-level EFT or lightning-induced surges.
Thermal design is supported by a 175°C maximum junction temperature and 0.400g package mass, while its 10/1000μs waveform rating aligns with IEC 61000-4-5 Level 4 immunity requirements. The device operates with <1μA leakage above 10V and exhibits a temperature coefficient of VBR at 0.057%/°C - critical for stable clamping across automotive under-hood temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.12V / 7.48V - Ensures reliable conduction onset within ±10% of nominal 6.8V across production lot and temperature |
| VWM | 5.5V - Safely isolates 5V digital circuits during normal operation with margin to logic-high thresholds |
| VC @ IPP | 10.8V @ 58A - Limits downstream voltage to safe levels for 5V-tolerant ICs during 600W transient events |
| PPK | 600W - Withstands IEC 61000-4-5 combination wave (1.2/50μs voltage + 8/20μs current) surges |
| IR @ VWM | <1μA - Prevents measurable standby current drain in battery-powered systems |
| Response Time | <5.0ns - Activates before most microcontroller I/O pins can be damaged by ESD (IEC 61000-4-2) |
| TJ max | 175°C - Supports operation in under-hood automotive environments and industrial motor drive enclosures |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.

| Lead 2 | Terminal B | Connects to reference plane (e.g., ground, chassis, or common return) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR and VC in both directions - eliminates need for orientation-aware placement on PCB |

| UL recognition | File #E-326243 - supports safety certification of end equipment without additional component-level testing |
Applications
| Automotive Sensor Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus sensors and analog temperature/pressure transducers from load dump and ISO 7637-2 pulse 5a/b transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed between sensor signal line and chassis ground to clamp surges before reaching ASIC input protection diodes. Use Value: Maintains signal integrity below 10.8V clamping threshold while surviving 600W pulses - prevents latch-up and parametric shift in automotive-grade op-amps. |
Use Scenario: Shielding D+ and D− lines of USB 2.0 host controllers from ESD events per IEC 61000-4-2 ±15kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance (≈100pF at 0V) bidirectional clamp placed adjacent to USB connector to shunt ESD current before it reaches PHY transceiver. Use Value: Sub-5ns response ensures clamping activation prior to PHY internal protection triggering - reduces bit error rate and port reset frequency. |
| Industrial PLC Digital Input Protection | DC Power Rail Surge Suppression |
Use Scenario: Safeguarding 24V digital input modules against induced surges from relay coil switching and nearby motor drives. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between field input terminal and module ground to absorb repetitive 10/1000μs transients up to 600W. Use Value: 5.5V VWM provides 1.5V margin above 4V logic-low threshold - avoids false triggering during brownout conditions. |
Use Scenario: Clamping 12V/24V DC power rails against lightning-induced surges entering via long cable runs in building automation systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp mounted at power entry point, upstream of DC-DC converters and LDO regulators. Use Value: 10.8V VC limits downstream voltage excursion to safe levels for 12V-rated components - prevents catastrophic failure of bulk capacitors and MOSFETs. |
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 6.8V nominal, but SMC package (DO-214AA); 600W rating; lower clamping voltage (11.2V @ 53.3A) | Surface-mount only; requires rework of footprint; better thermal dissipation in high-density layouts | Select SMBJ6.8CA when board space is constrained and automated assembly is preferred over through-hole insertion. |
| 1.5KE6.8CA | Same DO-204AC package; higher 1500W rating; higher clamping voltage (14.5V @ 103A); slower response (~10ns) | Overkill for 5V logic protection; suitable for 12–24V industrial power rails where higher energy handling is mandatory | Choose 1.5KE6.8CA only if system-level surge tests exceed 600W - otherwise P6KE6.8CA A0G offers optimal cost/performance balance. |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6.8CA A0G delivers the best trade-off of compact DO-204AC through-hole compatibility, precise 5.5V standoff for 5V systems, and verified 600W surge capability - making it ideal for legacy designs and prototyping where manual assembly or mechanical robustness is prioritized.

FAQ
What does the 'CA' suffix indicate in P6KE6.8CA A0G?
The 'CA' suffix denotes bidirectional configuration - meaning the P6KE6.8CA A0G functions identically in both polarities, with symmetric breakdown (6.12–7.48V) and clamping (10.8V) characteristics. This eliminates orientation concerns during placement and enables use on AC-coupled or differential signal lines like RS-485 or CAN, unlike unidirectional 'A' variants that require cathode alignment.
Is P6KE6.8CA A0G AEC-Q101 qualified?
P6KE6.8CA A0G itself is not AEC-Q101 qualified; qualification applies only to variants with the 'H' suffix (e.g., P6KE6.8CAH). However, the underlying P6KE6.8CA die construction and process are shared with AEC-Q101 versions, and the P6KE6.8CA A0G meets all electrical and mechanical specifications outlined in the same datasheet - making it suitable for non-automotive industrial and consumer applications requiring proven reliability.
How does P6KE6.8CA A0G compare to P6KE6.8A in terms of clamping performance?
P6KE6.8CA A0G has a maximum clamping voltage of 10.8V at 58A, while the unidirectional P6KE6.8A clamps at 10.5V at 60A. Though P6KE6.8A shows marginally lower VC, the P6KE6.8CA A0G maintains symmetrical clamping in both directions - critical for protecting bidirectional buses. Both share identical VBR range (6.12–7.48V) and 600W surge rating, but P6KE6.8CA A0G's bidirectional nature adds design flexibility at minimal VC trade-off.
What is the lead finish and solderability standard for P6KE6.8CA A0G?
P6KE6.8CA A0G features pure tin-plated leads compliant with J-STD-002 for solderability, ensuring reliable wetting during wave or hand soldering. The leads meet JEDEC JESD201 Class 2 whisker resistance requirements and are compatible with Pb-free and SnPb processes. The DO-204AC (DO-15) package uses UL 94V-0 rated epoxy molding compound, supporting reflow profiles up to 260°C peak temperature.
Can P6KE6.8CA A0G be used to protect a 3.3V logic line?
No - P6KE6.8CA A0G is not suitable for 3.3V logic protection because its 5.5V stand-off voltage (VWM) exceeds the 3.6V absolute maximum rating of most 3.3V ICs, risking premature conduction and increased leakage. For 3.3V systems, a TVS with VWM ≤3.0V (e.g., SMAJ3.3CA) is required. The P6KE6.8CA A0G is optimized for 5V interfaces where 5.5V VWM provides adequate margin without false triggering.
