Product details
Overview
P6KE100H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 100V nominal breakdown voltage (90–110V VBR), 81.0V stand-off voltage (VWM), 144V maximum clamping voltage at 4.3A peak surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE100H datasheet, P6KE100H pinout, P6KE100H application, or P6KE100H equivalent, key selection criteria include clamping performance under 10/1000µs transients, junction temperature derating above 25°C, unidirectional polarity marking, DO-204AC (DO-15) package compatibility with through-hole PCB layouts, and compliance with IEC 61249-2-21 halogen-free requirements.
Technical Context
The P6KE100H operates as a silicon avalanche diode that enters controlled breakdown when reverse voltage exceeds its VBR range (90–110V at 1mA test current), limiting transient energy by shunting surge current to ground. Its low dynamic impedance ensures rapid voltage clamping during fast-rising ESD or lightning-induced surges.
It is rated for non-repetitive 600W peak pulse power per 10/1000µs waveform, with thermal derating above 25°C ambient and a maximum junction temperature of 175°C. The device exhibits <1μA reverse leakage at 81V and a VBR temperature coefficient of 0.106%/°C - critical for stable clamping across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 81.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin. |
| VBR (min/max) | 90.0 / 110.0 V at 1 mA - Breakdown onset range; determines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 144 V at 4.3 A - Clamped voltage during full 600W surge; directly limits stress on downstream ICs. |
| PPK | 600 W - Peak pulse power handling per 10/1000µs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| TJMAX | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with proper PCB copper thermal relief. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage at rated stand-off voltage; prevents power loss in battery-backed or low-quiescent systems. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with tin-plated leads compliant with J-STD-002 solderability. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, RoHS-compliant, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-biased operation | Connected to protected line (e.g., +12V rail); current flows anode-to-cathode during clamping. |
| Cathode (banded end) | Clamp return path | Connected to ground or low-impedance return; establishes polarity-sensitive clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM/MM - supports Tier-1 supply chain compliance. |
| 600W 10/1000µs surge rating | Withstands IEC 61000-4-5 Combination Wave (1.2/50µs voltage + 8/20µs current) up to Level 4 without degradation. |
| Fast response time | <1.0 ps rise time from 0V to VBR - ensures clamping initiates before transient edges damage sensitive logic or analog inputs. |
| Low dynamic impedance | Enables tight clamping window (VC − VBR = 44 V max) - minimizes voltage overshoot seen by protected ICs. |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - required for automotive and industrial end-equipment environmental certifications. |
Applications

IC Role / Device Role / Timing Role: Front-end TVS on differential bus lines or analog input channels before signal conditioning amplifiers. Use Value: Clamps fast transients (<1ns rise) before they couple into precision ADC front-ends or op-amp stages. |
| LED Driver Input Protection | DC-DC Converter Input Stage |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same 100V nominal, but 600W rating in SMB (DO-214AA) surface-mount package; slightly higher VC (156V) and lower IPP (3.8A). | Requires SMT reflow process and board space optimization; not drop-in compatible with through-hole layouts. | Select SMBJ100A only when migrating to surface-mount design or needing tighter footprint control. |
| 1.5KE100A | Same DO-204AC package and 100V rating, but 1500W peak power (1.5kW), higher VC (156V), and larger physical size (DO-201AD). | Over-specified for 600W use cases; introduces unnecessary cost and board area unless legacy 1.5kW surge margin is mandated. | Choose 1.5KE100A only if system-level surge testing requires >600W headroom or existing 1.5KE footprint reuse is mandatory. |
Compared with SMBJ100A and 1.5KE100A, P6KE100H delivers optimal balance of AEC-Q101 qualification, through-hole manufacturability, and precise 600W clamping performance - making it the preferred choice for cost-sensitive, high-volume automotive and industrial power rail protection where DO-15 compatibility and automotive reliability are jointly required.

FAQ
What is the clamping voltage of P6KE100H at its rated peak surge current?
The P6KE100H has a maximum clamping voltage (VC) of 144 V at 4.3 A peak pulse current (IPP), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 600W transient event, ensuring downstream components remain within safe operating voltage margins. The P6KE100H maintains this clamping performance across its specified junction temperature range.
Is P6KE100H suitable for bidirectional transient suppression?
No, P6KE100H is a unidirectional TVS diode, indicated by its "H" suffix and absence of "CA" or "C" designation. It conducts only in reverse bias (cathode-to-anode) and must be installed with correct polarity - cathode tied to ground or reference plane. For bidirectional protection, select P6KE100CA or equivalent bipolar variants, which provide symmetrical clamping in both directions.
Does P6KE100H meet automotive qualification standards?
Yes, P6KE100H is explicitly AEC-Q101 qualified per the manufacturer's ordering information and datasheet notes. This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and electrostatic discharge (HBM/MM), confirming suitability for automotive powertrain, body electronics, and infotainment systems where reliability under extended temperature and vibration conditions is mandatory.
What is the maximum steady-state power dissipation for P6KE100H at 75°C ambient?
The P6KE100H has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This derated value reflects thermal limitations in continuous operation and is distinct from its 600W non-repetitive pulse rating. Designers must ensure PCB layout provides adequate copper area and airflow to maintain junction temperature below 175°C under sustained leakage or low-duty-cycle surge conditions.
How does the temperature coefficient affect P6KE100H's breakdown voltage stability?
P6KE100H has a maximum VBR temperature coefficient of 0.106 %/°C, meaning its breakdown voltage increases by up to 0.106% per degree Celsius rise in junction temperature. Over the full −55°C to +175°C range, this results in approximately ±12% VBR shift relative to 25°C - a critical factor in designs requiring tight clamping tolerance across wide ambient conditions, such as under-hood automotive modules.
