Product details
Overview
P6KE150CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 150V nominal standoff voltage, 215V maximum clamping voltage at 2.9A peak pulse current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive ECU power inputs and industrial sensor interface protection.
For engineers reviewing the P6KE150CA datasheet, P6KE150CA pinout, P6KE150CA application, or P6KE150CA equivalent, key selection criteria include bidirectional clamping symmetry, low dynamic impedance under surge, AEC-Q101 qualification status, junction temperature derating above 25°C, and compatibility with 10/1000μs waveform immunity testing per IEC 61000-4-5.
Technical Context
The P6KE150CA operates as a silicon avalanche diode with symmetrical breakdown in both polarities due to its CA suffix designation. Its 135–165V breakdown voltage range (measured at 1mA) ensures reliable triggering before downstream IC damage, while its <1.0ps response time enables suppression of fast transients such as ESD and EFT.
Thermal design relies on junction-to-ambient conduction through axial leads mounted on 5×5 mm copper pads; power derating follows a linear curve from 600W at 25°C to zero at 175°C TJ max. The device exhibits 0.108%/°C VBR temperature coefficient and <1μA reverse leakage above 128V standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 150 V - defines rated DC operating voltage threshold before clamping activation |
| Breakdown Voltage VBR | 135–165 V at 1 mA - ensures consistent avalanche initiation across production lot and temperature |
| Standoff Voltage VWM | 128 V - maximum continuous reverse voltage without significant leakage (<1 μA) |
| Clamping Voltage VC | 207 V at 3.0 A IPP - limits transient voltage seen by protected circuit during 10/1000μs surge |
| Peak Pulse Power PPK | 600 W - sustains single 10/1000μs surge without failure per JEDEC standards |
| Junction Temperature Range | −55°C to +175°C - supports operation in under-hood automotive and industrial ambient environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional variants; P6KE150CA is bidirectional and lacks polarity marking - terminals are non-polarized and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends function identically - no fixed anode/cathode; surge current flows bidirectionally through avalanche junction |
| Lead 1 / Lead 2 | Thermal and electrical interface | Sn-plated copper leads provide solderability per J-STD-002 and conduct heat to PCB copper pads for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC performance in both directions - eliminates need for orientation-aware layout |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control modules |
| Low clamping ratio | VC/VBR ≈ 1.45 - minimizes overvoltage stress on protected ICs compared to competing TVS devices |
| Fast transient response | <1.0 ps rise-time response - captures sub-nanosecond ESD events before propagation into sensitive analog front-ends |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets RoHS and automotive material compliance requirements |
Applications
| Automotive Power Input Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same 150V VWM and bidirectional configuration but in SMB surface-mount package (3.5×3.5mm); 600W rating at 10/1000μs; lower parasitic inductance | Preferred for space-constrained PCBs and automated SMT assembly; not suitable for through-hole or high-vibration mechanical mounting | Select SMBJ150CA when board real estate is limited and reflow compatibility is required |
| 1.5KE150CA | Same DO-15 package and 150V rating but higher 1500W peak power; larger junction area; higher clamping voltage (230V @ 6.5A) | Better suited for severe load-dump scenarios (e.g., ISO 7637-2 Pulse 5a) where higher energy absorption is mandatory | Select 1.5KE150CA only when system-level surge testing exceeds 600W requirements |
Compared with P6KE150CA, SMBJ150CA offers superior high-frequency surge handling in compact layouts, while 1.5KE150CA provides greater energy margin at the cost of higher clamping voltage and larger thermal mass - choice depends on PCB assembly method, mechanical robustness needs, and validated surge test profile.

FAQ
What is the clamping voltage of P6KE150CA at its rated peak pulse current?
The P6KE150CA has a maximum clamping voltage (VC) of 207 V at 3.0 A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during transient events, and is verified per ANSI/IEEE C62.35 test conditions.
Is P6KE150CA qualified for automotive applications?
Yes, P6KE150CA is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's documentation and UL recognition file #E-326243. It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD immunity, making it suitable for under-hood and body-control module deployments.
What does the "CA" suffix indicate in P6KE150CA?
The "CA" suffix in P6KE150CA denotes bidirectional configuration - meaning the device provides symmetrical avalanche breakdown and clamping in both forward and reverse directions. Unlike "A"-suffixed unidirectional parts, P6KE150CA has no cathode marking and can be installed without orientation constraints.
How does P6KE150CA compare to P6KE150A in terms of electrical performance?
P6KE150CA is bidirectional with matched VBR (135–165 V) and VC (207 V) in both polarities, whereas P6KE150A is unidirectional with cathode marking and slightly tighter VBR tolerance (143–158 V). Their standoff voltage (128 V), peak power (600 W), and thermal ratings are identical - selection depends solely on circuit polarity requirements.
What is the maximum junction temperature rating for P6KE150CA?
The P6KE150CA has a maximum junction temperature (TJ) rating of +175°C, with a storage temperature range of −55°C to +175°C. This allows reliable operation in high-ambient environments such as automotive engine compartments or industrial motor drives, provided PCB copper pad thermal relief meets the 5×5 mm specification.
