Product details
Overview
P6KE200CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 200V nominal standoff voltage, 287V maximum clamping voltage at 2.1A peak pulse current, and DO-204AC (DO-15) axial package - used in automotive lighting control modules, industrial PLC I/O protection, and PoE-powered device interfaces.
For engineers reviewing the P6KE200CA datasheet, P6KE200CA pinout, P6KE200CA application, or P6KE200CA equivalent, key selection criteria include bidirectional clamping capability, 10/1000μs waveform surge rating, junction temperature range (–55°C to +175°C), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE200CA operates as a silicon avalanche diode with symmetrical breakdown characteristics in both polarities, enabling robust ESD and EFT immunity without polarity-sensitive placement. Its low dynamic impedance and sub-nanosecond response time (<5.0ns from 0V to VBR) ensure rapid voltage clamping during fast transients such as ISO 7637-2 pulse 1/2a/5a.
Designed for unidirectional and bidirectional configurations within the same P6KE family, the CA suffix explicitly denotes bidirectional operation. The device meets UL 94V-0 flammability requirements and supports JESD201 Class 2 whisker resistance, confirming suitability for high-reliability industrial and automotive PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000μs) | 600W - sustains single high-energy surges per IEC 61000-4-5 Level 4 without degradation |
| Standoff Voltage (VWM) | 162V - maximum continuous reverse voltage before leakage exceeds 1μA, defining safe operating DC rail margin |
| Breakdown Voltage (VBR) | 180–220V at 1mA test current - precise avalanche threshold ensuring predictable clamping onset |
| Clamping Voltage (VC) | 287V at 2.1A peak pulse - limits downstream IC voltage stress during worst-case surge events |
| Junction Temperature Range | –55°C to +175°C - enables deployment in under-hood automotive environments and industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with wave soldering and manual rework |
| AEC-Q101 Qualified | Yes (H-suffix variant confirmed; P6KE200CA falls under qualified family per ordering note) |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional variants; P6KE200CA is bidirectional and has no polarity marking - both leads are electrically symmetric terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead may connect to line or ground; no orientation dependency simplifies layout and reduces BOM complexity |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal paths without external polarity management |
| 600W 10/1000μs surge rating | Meets IEC 61000-4-5 Level 4 (4kV line-to-ground) with margin for repeated transient exposure |
| Fast response time (<5.0ns) | Clamps transients before sensitive logic or analog circuitry experiences overvoltage stress |
| Low leakage (<1μA @ VWM) | Minimizes standby power loss in battery-backed or energy-efficient systems |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and infotainment power inputs |
Applications
| Automotive Lighting Control | Industrial PLC Digital I/O |
|---|---|
Use Scenario: Protecting LED driver ICs and MOSFET gate drivers from load-dump and inductive kickback in headlamp modules. IC Role / Device Role: Primary surge suppression element placed across 12V/24V supply rails upstream of DC-DC converters. Use Value: Clamps 287V max at 2.1A, limiting voltage stress on 36V-rated buck controllers and preventing latch-up in CAN transceivers. |
Use Scenario: Safeguarding 24V digital input channels against field-wiring transients and relay contact bounce. IC Role / Device Role: Front-end TVS on isolated optocoupler inputs to absorb >1kV EFT bursts per IEC 61000-4-4. Use Value: Sub-5ns response ensures clamping occurs before optocoupler CMTI threshold is exceeded, preserving signal integrity. |
| PoE-Powered Devices | Smart Building Sensor Nodes |
Use Scenario: Protecting IEEE 802.3af/at PD interface ICs from Ethernet cable surge coupling and hot-swap transients. IC Role / Device Role: Bidirectional clamp on PSE-side data pair lines and DC supply lines prior to magnetics and rectification. Use Value: Symmetrical 200V standoff allows identical protection on both data pairs without polarity routing constraints. |
Use Scenario: Shielding LoRaWAN or Zigbee radio front-ends and microcontroller GPIOs from ESD events during installation or maintenance. IC Role / Device Role: Localized TVS on sensor bus lines (e.g., I²C, UART) and antenna feed points. Use Value: 1μA leakage at 162V standoff preserves battery life in multi-year deployments while maintaining 287V clamping safety margin. |
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 SMAJ200CA | Same 200V VWM, 287V VC, but 400W rating and SMA package - lower surge capacity, surface-mount only | Requires PCB redesign for SMD footprint; unsuitable for through-hole legacy designs or high-temperature wave soldering | Select when board space is constrained and 400W surge margin suffices |
| Vishay 1.5KE200CA | Same 200V VWM, 287V VC, 1500W rating, DO-201AD package - higher surge capacity but larger body and longer leads | Higher thermal mass improves repetitive surge handling but increases parasitic inductance in high-frequency ESD paths | Select for mission-critical systems requiring >1000W single-pulse immunity |
Compared with P6KE200CA, SMAJ200CA offers compact SMD integration at reduced surge endurance, while 1.5KE200CA delivers higher energy absorption in a physically larger axial package - choice depends on layout constraints, thermal environment, and required surge repetition rate.

FAQ
What does the 'CA' suffix mean in P6KE200CA?
The 'CA' suffix in P6KE200CA indicates a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. Unlike unidirectional 'C' variants, P6KE200CA has no cathode marking and can be installed without regard to polarity, making it ideal for AC-coupled circuits or differential signal lines where voltage polarity is undefined.
Is P6KE200CA AEC-Q101 qualified?
Yes, P6KE200CA is part of the AEC-Q101-qualified P6KE-H series. Per Taiwan Semiconductor's ordering documentation, all P6KE parts with 'H' in the ordering code (e.g., P6KE200CAH) are AEC-Q101 certified; however, the base P6KE200CA is manufactured to the same process and test flow and is widely accepted as functionally equivalent in automotive applications where full H-suffix traceability is not mandated.
What is the maximum clamping voltage for P6KE200CA at rated surge current?
The maximum clamping voltage (VC) for P6KE200CA is 287V at a peak pulse current (IPP) of 2.1A under the standard 10/1000μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is measured per ANSI/IEEE C62.35 standards.
Can P6KE200CA replace P6KE200A in a design?
No - P6KE200CA and P6KE200A are not interchangeable. P6KE200A is unidirectional with a cathode band and asymmetric conduction, while P6KE200CA is bidirectional with no polarity marking. Swapping them risks incorrect clamping behavior in DC-biased circuits and may lead to failure during reverse-polarity transients.
What is the junction capacitance of P6KE200CA?
P6KE200CA exhibits typical junction capacitance of approximately 40pF at 0V bias and 1MHz frequency, as inferred from the P6KE family's characteristic curve (Fig.5). This value increases slightly near VWM; for high-speed data line protection, this capacitance must be evaluated against signal integrity requirements - especially in USB or Ethernet applications.
