Product details
Overview
P6KE350CA 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 350V nominal standoff voltage (VWM = 284V), 315–385V breakdown range (VBR), 504V maximum clamping voltage at 1.2A peak surge current, and 600W peak pulse power rating per 10/1000μs waveform - deployed in automotive lighting control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE350CA datasheet, P6KE350CA pinout, P6KE350CA application, or P6KE350CA equivalent, key selection criteria include bidirectional clamping capability, low dynamic impedance under fast transients (<5ns response), AEC-Q101 qualification status, and DO-204AC (DO-15) package compatibility with legacy through-hole PCB layouts.
Technical Context
The P6KE350CA operates as a silicon avalanche diode with symmetrical bidirectional breakdown behavior - enabling identical clamping performance in both polarities without external polarity management. Its junction structure delivers low dynamic impedance (<1Ω typical) and sub-5ns response time from 0V to VBR, critical for suppressing EFT bursts and inductive switching spikes.
Thermal design is governed by a 175°C maximum junction temperature and derated power dissipation above 25°C ambient, with steady-state power handling of 5W at 75°C on 5×5 mm copper pads. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 284 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin for 350V nominal systems |
| VBR (min/max) | 315 / 385 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on during overvoltage events |
| VC @ IPP | 504 V @ 1.2 A - Clamped voltage during 10/1000μs surge; limits downstream IC stress to <504 V under worst-case 600W transient |
| PPK | 600 W - Peak pulse power handling per standard 10/1000μs waveform; supports IEC 61000-4-5 Level 4 surge immunity |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with 0.400 g mass; compatible with wave soldering and manual rework |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional variants; P6KE350CA is bidirectional and marked without polarity band - terminals are non-polarized and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output terminal; no polarity dependency - simplifies layout and eliminates orientation errors |
| Lead 1 | Terminal A | Plated with pure tin per J-STD-002; supports automated and hand soldering with 9.5 mm lead length thermal relief |
| Lead 2 | Terminal B | Identical to Lead 1; symmetric construction allows direct series/parallel TVS stacking without polarity matching |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without external diode pairing |
| 5 ns response time | Guarantees suppression of fast EFT transients (IEC 61000-4-4) before sensitive logic inputs are exposed |
| UL 94V-0 molding compound | Prevents flame propagation in enclosed industrial and automotive housings during fault conditions |
| JESD201 Class 2 whisker resistance | Eliminates tin whisker growth risk in long-life applications such as transportation and energy infrastructure |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained deployments |

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 SMAJ350CA | Same DO-214AC (SMA) package; 350V VWM, 504V VC @ 1.2A, but rated for 400W not 600W peak power | Lower surge rating limits use to Level 3 IEC 61000-4-5; unsuitable for automotive load-dump scenarios requiring 600W | Select P6KE350CA when 600W 10/1000μs surge headroom is mandatory and DO-15 through-hole mounting is required |
| Vishay 1.5KE350CA | Same DO-204AC (DO-15) package and 600W rating; identical VWM/VBR/VC specs but lacks AEC-Q101 qualification | Not validated for automotive temperature cycling or HTRB; requires additional qualification effort for vehicle programs | Choose P6KE350CA for AEC-Q101-compliant designs where zero additional reliability validation is needed |
Compared with SMAJ350CA and 1.5KE350CA, P6KE350CA uniquely combines 600W surge capability, DO-15 through-hole compatibility, and factory-certified AEC-Q101 qualification - eliminating trade-offs between power rating, package fit, and automotive compliance.

FAQ
What is the maximum clamping voltage of the P6KE350CA under a 10/1000μs surge?
The P6KE350CA has a maximum clamping voltage (VC) of 504 V when subjected to its rated peak pulse current of 1.2 A under the standard 10/1000μs waveform. This value is measured at the device's specified test condition and ensures downstream circuitry remains below critical voltage thresholds during surge events. The P6KE350CA maintains this clamping performance bidirectionally, making it suitable for both AC and DC transient suppression applications.
Is the P6KE350CA qualified to AEC-Q101 standards?
Yes, the P6KE350CA is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - validating its suitability for automotive under-hood and cabin applications. The "H" suffix in ordering codes (e.g., P6KE350CAH) denotes AEC-Q101 compliance, and P6KE350CA falls within the qualified voltage range excluding only the lowest-voltage variants.
What is the standoff voltage (VWM) and breakdown voltage range for the P6KE350CA?
The P6KE350CA has a maximum working peak reverse voltage (VWM) of 284 V and a breakdown voltage (VBR) range of 315 V to 385 V at 1 mA test current. This VBR window ensures reliable turn-on during overvoltage events while maintaining low leakage (<1 μA) at rated operating voltage. These parameters are strictly defined in the Electrical Specifications table of the P6KE350CA datasheet and apply identically in both directions due to its bidirectional construction.
Can the P6KE350CA be used in place of unidirectional TVS diodes like P6KE350A?
No - the P6KE350CA is specifically a bidirectional device, whereas P6KE350A is unidirectional. Substituting P6KE350CA for P6KE350A introduces symmetrical clamping that may interfere with DC-biased signal paths or rectifier-based circuits relying on polarity-dependent conduction. The P6KE350CA must only replace other CA-suffixed parts; its cathode band is omitted per marking diagram, confirming its non-polarized design. Always verify circuit topology before interchange.
What package type does the P6KE350CA use, and what are its mechanical characteristics?
The P6KE350CA uses the DO-204AC (DO-15) axial-leaded package, with dimensions conforming to JEDEC standards and a typical weight of 0.400 g. Its molding compound meets UL 94V-0 flammability rating, leads are pure tin-plated per J-STD-002, and it passes JESD201 Class 2 whisker testing. The device is supplied in tape-and-reel (3,500 pcs) or ammo box (1,500 pcs) formats, supporting both automated and manual assembly processes.
