Product details
Overview
P6KE9V1CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in power rails and signal lines. It features a nominal breakdown voltage of 9.1 V, clamps transients to ≤13.4 V at 50 A peak surge current, and delivers sub-5 ns response time. It is used in automotive lighting control modules to protect CAN transceiver inputs against load-dump-induced spikes.
For engineers reviewing the P6KE9V1CA datasheet, P6KE9V1CA pinout, P6KE9V1CA application, or P6KE9V1CA equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, 13.4 V clamping voltage at 50 A, and AEC-Q101 qualification status - critical for under-hood automotive designs requiring high-reliability transient immunity.
Technical Context
The P6KE9V1CA is a silicon avalanche diode operating in reverse-biased breakdown mode, with symmetrical bidirectional conduction enabling protection against both positive and negative transients without polarity sensitivity. Its low dynamic impedance (<0.3 Ω typical) ensures rapid voltage clamping during fast-rising EFT or lightning-induced surges.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive load dump) immunity standards when applied with proper PCB layout. The device's 175 °C maximum junction temperature and -55 °C to +175 °C operating range support deployment in engine control units and powertrain electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges common in automotive load-dump events |
| Breakdown Voltage VBR (min/max) | 8.65 V / 9.55 V at 1 mA - defines reliable turn-on threshold across temperature and unit variation |
| Stand-off Voltage VWM | 7.78 V - maximum continuous DC or RMS voltage before leakage exceeds 1 µA |
| Clamping Voltage VC @ IPP = 50 A | 13.4 V - peak voltage seen by protected IC during worst-case surge, limiting stress on downstream logic |
| Junction Temperature Range | -55 °C to +175 °C - enables operation in under-hood environments without derating |
| Response Time | <5.0 ns - ensures suppression activation before transient energy damages sensitive CMOS inputs |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking for unidirectional variants; P6KE9V1CA is bidirectional and marked without polarity band. Leads are pure tin-plated, solderable per J-STD-002, and pass JESD201 Class 2 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | No polarity dependency - either lead connects to protected line or ground; enables flexible PCB routing |
| Lead 1 / Lead 2 | Current conduction terminals | Both leads carry full surge current; no internal series resistance or integrated fuse - requires external coordination |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional TVS architecture | Protects AC-coupled or floating signal paths (e.g., RS-485, CAN bus) without polarity constraints |
| AEC-Q101 qualified (H-suffix variant only) | P6KE9V1CA is *not* AEC-Q101 qualified; H-suffix versions exist but P6KE9V1CA uses standard industrial qualification |
| Low clamping ratio (VC/VBR) | 13.4 V / 9.1 V ≈ 1.47 - tighter than typical 1.6+ ratio, reducing overvoltage margin for protected ICs |
| Sub-1 µA leakage @ VWM | ≤1 µA at 7.78 V - avoids parasitic loading on low-power sensor supply rails or battery-backed circuits |
| UL 94V-0 flammability rating | Molding compound self-extinguishes within 10 seconds after flame removal - meets safety requirements for enclosed automotive modules |
Applications
| Automotive Lighting Control | Industrial PLC I/O Protection |
|---|---|

IC Role / Device Role / Timing Role: Bidirectional clamp on isolated input optocoupler front-end, referenced to local ground. Use Value: Maintains signal integrity by suppressing >8 kV contact ESD (IEC 61000-4-2) without adding capacitance that degrades 10 kHz switching response. |
| USB-C Port ESD Protection | Smart Meter Communication Interface |
Use Scenario: Secondary-level ESD protection on USB-C CC and VCONN lines in automotive infotainment docking stations. IC Role / Device Role / Timing Role: Back-to-back TVS pair (using two P6KE9V1CA) across differential pairs to handle ±15 kV air discharge. Use Value: Achieves <1 pF junction capacitance (per diode) at 0 V bias, minimizing signal distortion on 10 Mbps USB 2.0 data paths. |
Use Scenario: Protecting RS-485 transceivers in utility smart meters exposed to lightning-induced surges on long outdoor communication lines. IC Role / Device Role / Timing Role: Line-to-line and line-to-ground TVS on twisted-pair bus, rated for 600 W unidirectional pulse handling. Use Value: Withstands 4 kV surge (IEC 61000-4-5, 10/700 µs) while maintaining common-mode rejection >60 dB up to 1 MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA (Bourns) | Same DO-214AA package; 600 W rating; VBR = 10.0–11.1 V; VC = 15.4 V @ 38.9 A | Higher clamping voltage reduces margin for 9 V rail systems; surface-mount footprint requires PCB redesign | Select when SMT assembly is mandatory and clamping voltage margin allows ≥15.4 V |
| 1.5KE9.1CA (ON Semiconductor) | Same DO-204AC package; 1500 W rating; VBR = 8.65–9.55 V; VC = 14.5 V @ 103 A | Higher surge capacity suits repeated surge exposure; larger thermal mass delays failure under sustained overstress | Select for industrial motor drives where multi-pulse surge immunity is prioritized over compact size |
Compared with P6KE9V1CA, SMBJ9.0CA trades lower clamping performance for SMT compatibility, while 1.5KE9.1CA offers higher surge endurance in the same through-hole form factor - making it suitable for applications with frequent transient exposure but identical board space constraints.

FAQ
What is the exact breakdown voltage range for P6KE9V1CA?
The P6KE9V1CA has a guaranteed breakdown voltage (VBR) range of 8.65 V to 9.55 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable turn-on behavior across production lots and temperature extremes, supporting robust design margins in 9 V nominal systems. The P6KE9V1CA maintains this specification across its full operating junction temperature range.
Is P6KE9V1CA AEC-Q101 qualified?
No, P6KE9V1CA is not AEC-Q101 qualified. Per Taiwan Semiconductor's ordering information, AEC-Q101 qualification applies only to "H" suffix variants (e.g., P6KE9V1CAH), and explicitly excludes P6KE6V8A through P6KE9V1A. The P6KE9V1CA carries industrial-grade qualification and meets RoHS, halogen-free (IEC 61249-2-21), and UL 94V-0 requirements, but lacks automotive stress-test validation.
What is the maximum clamping voltage of P6KE9V1CA under surge conditions?
The P6KE9V1CA clamps to a maximum of 13.4 V when subjected to a 50 A peak pulse current with a 10/1000 µs waveform. This value is specified in the Electrical Specifications table and represents the worst-case voltage seen by protected circuitry during standardized surge testing. It directly determines the overvoltage margin available for downstream ICs operating at 9 V or 12 V rails.
Can P6KE9V1CA be used in bidirectional signal line protection?
Yes, P6KE9V1CA is explicitly designed as a bidirectional TVS diode, with identical electrical characteristics in both polarities. Its symmetrical breakdown behavior makes it suitable for protecting AC-coupled interfaces such as RS-485, CAN, or audio lines - unlike unidirectional variants (e.g., P6KE9V1A) which require correct polarity orientation. The P6KE9V1CA datasheet confirms bidirectional use for types P6KE6.8 through P6KE440 with "C" or "CA" suffixes.
What package type does P6KE9V1CA use, and what are its mechanical highlights?
P6KE9V1CA uses the DO-204AC (DO-15) axial-leaded package, featuring pure tin-plated leads compliant with J-STD-002 solderability standards and passing JESD201 Class 2 whisker testing. Its molding compound meets UL 94V-0 flammability rating, and the device weighs approximately 0.400 g. Polarity marking is omitted due to its bidirectional functionality - a key mechanical distinction from unidirectional P6KE variants.
