Product details
Overview
P6KE100CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 100V nominal breakdown voltage, 600W peak pulse power rating at 10/1000μs waveform, clamping voltage of 144V at 4.3A peak surge current, and operates across –55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial PLC I/O protection circuits.
For engineers reviewing the P6KE100CA datasheet, P6KE100CA pinout, P6KE100CA application, or P6KE100CA equivalent, key selection criteria include bidirectional clamping capability, low dynamic impedance, AEC-Q101 qualification status, standoff voltage of 81V, and DO-204AC (DO-15) package compatibility with through-hole PCB layouts.
Technical Context
The P6KE100CA implements a silicon avalanche diode structure optimized for fast transient response (<5.0ns for bidirectional operation) and stable clamping under repetitive surge stress. Its bidirectional configuration enables symmetrical voltage limiting in AC-coupled or floating systems without polarity dependency.
It meets UL 94V-0 flammability requirements, supports JESD201 Class 2 whisker resistance, and delivers <1μA reverse leakage at 81V standoff - ensuring minimal standby power loss in always-on protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 10/1000μs waveform - sustains single high-energy surges common in automotive load dump or inductive switching events |
| Breakdown Voltage VBR | 90–110V at 1mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Clamping Voltage VC | 144V at 4.3A IPP - limits downstream circuit voltage during surge, protecting 100V-rated components |
| Standoff Voltage VWM | 81V maximum - ensures no conduction during normal 72–80V DC bus operation (e.g., 72V commercial vehicle systems) |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive placement and industrial high-temp environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded through-hole package with 0.400g mass and tin-plated leads |
| AEC-Q101 Qualified | Yes (H-suffix variant confirmed) - validated for automotive electronics per stress test requirements including temperature cycling and HTRB |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking on one end; no polarity distinction required for bidirectional operation - terminals are non-polarized and function identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Both ends serve as interchangeable terminals; clamping occurs equally in both directions above ±90V |
| Leads (Tin-plated) | PCB interconnect and thermal path | Solderable per J-STD-002; 5×5 mm copper pad mounting recommended for full 600W derating |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating DC busses without external polarity management |
| Low dynamic impedance | Ensures rapid voltage stabilization during surge, minimizing overshoot beyond clamping level |
| Fast response time | <5.0ns turn-on from 0V to VBR - critical for suppressing EFT bursts and lightning-induced transients |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units and body electronics |
| UL recognition (E-326243) | Confirms safety compliance for end-equipment certification in North American markets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA (Bourns) | Same 100V nominal, 600W rating, but SMB package (surface-mount); lower clamping voltage (137V @ 4.3A) | Requires SMT layout; better thermal performance in compact designs but lacks axial-leaded mechanical robustness | Select when board space is constrained and reflow assembly is used |
| 1.5KE100CA (ON Semiconductor) | Same DO-204AC package and 100V rating, but 1500W rating; higher clamping voltage (150V @ 12.3A) | Over-specified for 600W use cases; larger junction capacitance may affect high-speed signal lines | Select when legacy design uses 1.5KE series or higher surge margin is required |
Compared with SMBJ100CA and 1.5KE100CA, the P6KE100CA offers optimal balance of axial-leaded mechanical reliability, AEC-Q101 qualification, and precise 144V clamping - making it preferred for cost-sensitive, through-hole automotive and industrial power rail protection where 600W surge capacity suffices.

FAQ
What is the clamping voltage of the P6KE100CA and how is it measured?
The P6KE100CA has a maximum clamping voltage (VC) of 144V at 4.3A peak pulse current (IPP), measured using a 10/1000μs standard surge waveform. This value represents the upper voltage limit imposed on protected circuitry during a defined transient event - critical for ensuring downstream components rated at 100V or higher remain within safe operating limits. The P6KE100CA achieves this clamping performance consistently across its –55°C to +175°C operating range.
Is the P6KE100CA suitable for automotive applications?
Yes, the P6KE100CA is AEC-Q101 qualified when ordered with the "H" suffix (e.g., P6KE100CAH), confirming compliance with stress tests for automotive electronics including temperature cycling, highly accelerated life testing, and humidity bias. Its 175°C maximum junction temperature and DO-204AC mechanical robustness make the P6KE100CA appropriate for under-hood and body-control module deployments where reliability under thermal and vibration stress is essential.
How does the bidirectional configuration of the P6KE100CA affect circuit design?
The P6KE100CA's bidirectional architecture eliminates polarity sensitivity - both terminals function identically, enabling placement across floating nodes or AC-coupled signals without orientation constraints. This simplifies layout, reduces BOM complexity versus dual-unidirectional solutions, and ensures symmetrical clamping behavior during positive and negative transients. In practice, the P6KE100CA is installed directly across power rails or signal/ground pairs without regard to lead direction.
What is the standoff voltage rating of the P6KE100CA and why does it matter?
The P6KE100CA has a maximum standoff voltage (VWM) of 81V, meaning it remains non-conductive below this DC or RMS voltage level. This parameter ensures no leakage current or power loss during normal operation - for example, in a 72V battery-powered system, the P6KE100CA stays fully off while still responding instantly to surges exceeding 90V. Maintaining adequate margin between VWM and system operating voltage prevents false triggering and extends device service life.
Can the P6KE100CA be used in place of the P6KE100A?
No - the P6KE100CA and P6KE100A are not interchangeable. The "CA" suffix denotes bidirectional configuration, while "A" indicates unidirectional operation with cathode marking. Substituting P6KE100CA for P6KE100A would remove polarity control in circuits relying on directional clamping, potentially causing malfunction in DC-biased protection schemes. Always verify suffix meaning: P6KE100CA provides symmetrical clamping; P6KE100A clamps only in reverse bias and conducts forward like a rectifier.
