Product details
Overview
P6KE160CA 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 160V nominal standoff voltage, 176V maximum breakdown voltage at 1mA test current, 136V maximum stand-off voltage, clamps to ≤219V at 2.8A peak surge current, and uses DO-204AC (DO-15) axial package - deployed in automotive lighting control modules to absorb load-dump transients.
For engineers reviewing the P6KE160CA datasheet, P6KE160CA pinout, P6KE160CA application, or P6KE160CA 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 P6KE160CA operates as a silicon avalanche diode with symmetrical bidirectional breakdown behavior, enabling protection against both positive and negative polarity transients without external polarity management. Its low dynamic impedance ensures rapid voltage clamping during fast-rising ESD or EFT events, while its <1.0ps response time (unidirectional reference) and 5.0ns response (bidirectional) support compliance with IEC 61000-4-2 and IEC 61000-4-4 standards.
Thermal design is enabled by a 175°C maximum junction temperature and derating curves supporting operation up to 125°C ambient. The device meets UL 94V-0 flammability requirements, RoHS Directive 2011/65/EU, and IEC 61249-2-21 halogen-free specifications - confirming suitability for surface-mount-compatible through-hole assembly in industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; defines safe operating DC bias margin. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed symmetric avalanche threshold in both directions; ensures predictable clamping onset. |
| VC @ IPPM (Clamping Voltage) | 219 V at 2.8 A - Peak voltage seen by protected circuit during 10/1000μs surge; determines downstream component stress. |
| PPK (Peak Pulse Power) | 600 W - Energy-handling capacity per single non-repetitive 10/1000μs transient; validates robustness against ISO 7637-2 pulse 5a. |
| TJ Max | +175 °C - Maximum junction temperature; enables use in under-hood automotive locations with minimal thermal derating. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off; minimizes standby power loss in always-on systems. |
| Package | DO-204AC (DO-15) - Axial-leaded, JEDEC-standard package with tin-plated leads compliant to J-STD-002 solderability. |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional variants; P6KE160CA is bidirectional and marked without polarity indicator - terminals are functionally interchangeable. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No fixed anode/cathode assignment; either lead connects to protected line or ground - enables flexible PCB layout. |
| Lead 1 / Lead 2 | Current path for surge conduction | Both leads conduct equally during ± transient events; no PCB polarity orientation required for mounting. |

|---|---|
|
Use Scenario: Protecting LED driver ICs and MOSFET gate drivers in headlamp modules subjected to battery load-dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Bidirectional TVS placed across power rail and ground to clamp surges before they reach sensitive driver ICs. Use Value: Limits voltage to ≤219V during 600W transients, preventing overvoltage failure of 200V-rated MOSFETs and maintaining functional safety integrity. |
Use Scenario: Shielding digital input channels on programmable logic controllers exposed to inductive switching noise from solenoid valves. IC Role / Device Role / Timing Role: TVS connected between field input line and common reference to shunt fast-rising transients induced by relay coil de-energization. Use Value: Clamps 10/1000μs spikes within 5.0ns, reducing false triggering of optocoupler inputs and eliminating need for additional RC filtering. |
| USB Port ESD Protection | DC Power Rail Surge Suppression |
|
Use Scenario: Safeguarding USB 2.0 data lines (D+/D−) in automotive infotainment head units against human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed differentially across D+ and D− to divert ESD current away from USB transceiver. Use Value: Sub-1μA leakage at 136V stand-off avoids signal integrity degradation while providing ≥±15kV HBM protection per IEC 61000-4-2. |
Use Scenario: Protecting 24V DC power distribution networks in factory automation equipment from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: TVS installed between VIN and GND at power entry point to absorb multi-kA surge energy before reaching DC-DC converters. Use Value: Handles 2.8A peak surge current at 219V clamping level, preserving downstream regulator input ratings and avoiding brownout resets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA (Bourns) | Same 160V nominal, 600W rating, but SMB package (surface-mount); lower thermal resistance (30°C/W vs. DO-15's ~50°C/W). | Requires rework of PCB footprint; better suited for space-constrained designs with automated SMT assembly. | Select SMBJ160CA when board area is limited and thermal performance must be maximized via copper pour. |
| 1.5KE160CA (ON Semiconductor) | Identical DO-204AC package and 160V rating, but 1.5kW peak power rating (10/1000μs); higher clamping voltage (234V @ 6.4A). | Over-spec'd for 600W needs; introduces higher voltage stress on protected ICs during clamping. | Choose 1.5KE160CA only if future system-level surge testing requires headroom beyond 600W baseline. |
Compared with SMBJ160CA and 1.5KE160CA, the P6KE160CA offers optimal balance of proven automotive qualification (AEC-Q101), axial through-hole manufacturability, and precise 600W clamping performance - making it ideal for cost-sensitive, high-reliability DC power line protection where layout flexibility and legacy assembly compatibility matter.

FAQ
What is the clamping voltage of P6KE160CA at its rated peak surge current?
The P6KE160CA clamps to a maximum of 219 V at its specified peak pulse current of 2.8 A under the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the manufacturer's electrical specifications table for the P6KE160A variant, which shares identical clamping characteristics with P6KE160CA due to shared die and packaging construction.
Is P6KE160CA AEC-Q101 qualified?
Yes, P6KE160CA is AEC-Q101 qualified. Per the ordering information section of the Taiwan Semiconductor datasheet, the "H" suffix denotes AEC-Q101 qualification, and P6KE160CA falls within the voltage range (P6KE6.8 to P6KE440) explicitly covered under this qualification - excluding only the lowest-voltage variants (P6KE6V8A–P6KE9V1A). Certification applies to the full DO-204AC packaged device.
What is the difference between P6KE160CA and P6KE160A?
P6KE160CA is the bidirectional version, while P6KE160A is unidirectional. Both share identical breakdown (152–168 V), stand-off (136 V), and clamping (219 V) specifications, but P6KE160CA conducts surge current symmetrically in both polarities - critical for AC-coupled or differential signal protection - whereas P6KE160A requires correct cathode orientation and only protects against one polarity unless paired.
What package type does P6KE160CA use and what are its mechanical features?
P6KE160CA uses the DO-204AC (DO-15) axial package with 0.400 g mass, pure tin-plated leads compliant to J-STD-002, and UL 94V-0 molding compound. Polarity is not marked because it is bidirectional; the device meets JESD 201 Class 2 whisker resistance and is rated for manual or wave-solder assembly with 9.5 mm lead length thermal derating conditions.
Can P6KE160CA be used in place of P6KE150CA for higher-voltage margin?
Yes, P6KE160CA can replace P6KE150CA where higher stand-off voltage is needed - its 136 V VWM exceeds P6KE150CA's 128 V, reducing leakage and improving noise immunity in 150 V nominal systems. However, clamping rises to 219 V (vs. 207 V), so verify protected ICs tolerate the 12 V increase; no PCB changes are required as both share DO-204AC package and bidirectional functionality.
