Product details
Overview
P6KE11C from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 11 V, clamps transients to ≤16.2 V at 38 A peak surge current, and delivers sub-nanosecond response time (<1.0 ps from 0 V to VBR) - critical for safeguarding automotive ECUs against ISO 7637-2 pulse 1/2a/5a-induced surges.
For engineers reviewing the P6KE11C datasheet, P6KE11C pinout, P6KE11C application, or P6KE11C equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 8.92 V stand-off voltage, <1 μA reverse leakage at VWM, 175 °C maximum junction temperature, and AEC-Q101 qualification status - all essential for robust ESD and EFT immunity design in automotive and industrial control systems.
Technical Context
The P6KE11C operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled avalanche breakdown to clamp transient voltages above its 9.9–12.1 V VBR range. Its low dynamic impedance ensures stable clamping performance under 10/1000 µs surge waveforms up to 600 W, while its <1.0 ps response time enables effective suppression of fast-rising ESD events before downstream ICs are stressed.
Thermal derating follows a linear curve above 25 °C ambient, maintaining 600 W peak pulse power only at TA ≤ 25 °C and reducing to ~400 W at 75 °C. The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supporting inductive load switching protection in relay drivers and solenoid interfaces without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.92 V - Maximum continuous DC or RMS operating voltage before leakage exceeds 1 µA; defines safe working margin below breakdown. |
| VBR (min/max) | 9.90–12.1 V at 1 mA test current - Confirmed avalanche onset range; ensures reliable triggering across process and temperature variation. |
| VC @ IPP | 16.2 V at 38 A peak pulse - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge; determines minimum IC withstand rating. |
| PPK | 600 W - Peak pulse power handling per 10/1000 µs waveform; defines single-event surge energy absorption capability. |
| IR @ VWM | <1 µA - Reverse leakage current at stand-off voltage; ensures negligible standby power loss and minimal signal distortion. |
| TJMAX | 175 °C - Maximum junction temperature; supports operation in under-hood automotive environments and high-power industrial enclosures. |
| Package | DO-204AC (DO-15) - Axial-leaded, through-hole package with 0.400 g mass; compatible with standard wave soldering and manual rework. |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; forms return path during clamping conduction. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V rail); avalanche conduction initiates here when VAK exceeds VBR. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ11A | Same DO-214AC (SMA) package; 11 V nominal, 17.5 V clamping at 34.1 A; 400 W rating; no AEC-Q101 option. | Surface-mount only; lower surge rating limits use in high-energy automotive load-dump scenarios. | Select when board space is constrained and surge energy is ≤400 W; verify thermal pad layout for 175 °C operation. |
| ON Semiconductor 1.5KE11C | Same DO-204AC (DO-15) package; 11 V nominal, 17.5 V clamping at 34.1 A; 1500 W rating; AEC-Q101 qualified. | Higher clamping voltage increases stress on downstream ICs; higher power rating requires larger PCB copper for thermal dissipation. | Select when system-level surge threat exceeds 600 W (e.g., heavy-duty truck load dump); confirm layout supports 1.5 kW pulse thermal management. |
Compared with Littelfuse SMAJ11A and ON Semi 1.5KE11C, the P6KE11C offers optimal balance of AEC-Q101 compliance, axial through-hole mounting, 600 W surge capacity, and 16.2 V clamping - making it preferred for cost-sensitive, thermally constrained automotive and industrial control designs where 1.5 kW devices are over-specified.

FAQ
What is the exact breakdown voltage range for P6KE11C at 1 mA test current?
The P6KE11C has a guaranteed breakdown voltage range of 9.90 V to 12.1 V when measured at 1 mA DC test current per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures reliable triggering across temperature extremes from –55 °C to +175 °C. The P6KE11C datasheet specifies this as VBR(min)/VBR(max) and is validated during 100% production testing.
Is P6KE11C suitable for bidirectional transient protection?
No, P6KE11C is a unidirectional TVS diode intended only for DC rail or polarized signal line protection. Its cathode band marking indicates polarity, and it conducts only when anode-to-cathode voltage exceeds VBR. For bidirectional AC or differential line protection (e.g., RS-485), a CA-suffixed part like P6KE11CA must be used - the P6KE11C lacks symmetrical breakdown characteristics in reverse bias.
Does P6KE11C meet AEC-Q101 qualification requirements?
Yes, P6KE11C is AEC-Q101 qualified per the manufacturer's ordering code documentation. The "H" suffix (e.g., P6KE11CH) explicitly denotes AEC-Q101 compliance, and Taiwan Semiconductor confirms qualification for the entire P6KE series except P6KE6V8A through P6KE9V1A. The P6KE11C meets stress tests including HTGB, H3TRB, and mechanical shock per AEC-Q101 Rev D.
What is the maximum clamping voltage of P6KE11C under 10/1000 µs surge conditions?
The P6KE11C clamps to a maximum of 16.2 V when subjected to its rated 38 A peak pulse current (IPP) under the standardized 10/1000 µs double-exponential waveform. This value is measured at TA = 25 °C and represents the worst-case voltage imposed on the protected circuit during surge conduction - a critical parameter for verifying compatibility with downstream IC absolute maximum ratings.
Can P6KE11C be used in surface-mount designs?
No, P6KE11C uses the DO-204AC (DO-15) axial through-hole package and is not suitable for surface-mount assembly. Its leaded construction requires plated-through holes and wave or selective soldering. For SMT implementation, engineers should select functionally equivalent devices such as SMAJ11A (DO-214AC) or SMCJ11A (DO-214AB), which share similar electrical specs but differ in package, thermal profile, and mounting method.
