Product details
Overview
P6KE180CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 180 V, clamps transients to ≤246 V at 2.5 A peak pulse current, and delivers fast response (<5 ns) with low dynamic impedance. It is used in automotive lighting control modules to protect CAN transceiver inputs against ISO 7637-2 load dump and EFT bursts.
For engineers reviewing the P6KE180CA datasheet, P6KE180CA pinout, P6KE180CA application, or P6KE180CA equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, 154 V standoff voltage, and AEC-Q101 qualification for automotive-grade reliability under thermal cycling and mechanical shock.
Technical Context
The P6KE180CA operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior-identical electrical characteristics in both polarities. Its junction structure enables sub-5 ns response to 10/1000 µs transients while maintaining <1 µA reverse leakage above 154 V at 25°C.
Thermal performance is defined by a 175°C maximum junction temperature and derating curves per Fig.2; power dissipation drops linearly above 25°C ambient, reaching ~50% at 100°C. The device uses pure tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000µs) | 600 W - sustains single high-energy surges without failure, e.g., ISO 7637-2 Pulse 5a |
| Standoff Voltage VWM | 154 V - maximum continuous DC voltage before significant leakage; sets operating margin below 180 V nominal |
| Breakdown Voltage VBR (min/max) | 171 V / 189 V - guaranteed avalanche onset range at 1 mA test current; ensures consistent clamping threshold |
| Clamping Voltage VC @ IPP=2.5A | 246 V - maximum voltage seen by protected circuit during surge; defines worst-case stress on downstream ICs |
| Reverse Leakage ID @ VWM | <1 µA - negligible standby power loss and minimal loading on high-impedance sensor or bus lines |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive placement and industrial environments with wide thermal swings |
| AEC-Q101 Qualified | Yes - validated for automotive use including temperature cycling, mechanical shock, and humidity bias life testing |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case meeting UL 94V-0 flammability rating. Cathode band marking omitted due to bidirectional symmetry; polarity is non-directional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity; no orientation required during PCB placement |
| Lead 1 | Terminal connection | Pure tin-plated copper lead, solderable per J-STD-002; supports wave and reflow processes |
| Lead 2 | Terminal connection | Identical to Lead 1; symmetric construction eliminates assembly errors in bidirectional applications |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN) without polarity concerns |
| 600 W surge rating (10/1000 µs) | Withstands automotive load dump events per ISO 7637-2 Level III (Pulse 5a) without degradation |
| Fast response time <5 ns | Clamps ESD and EFT transients before sensitive logic or analog circuits experience overstress |
| AEC-Q101 qualification | Validated for automotive electronics including engine control units, body controllers, and lighting systems |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained supply chains |
Applications
| Automotive Lighting Control | Industrial CAN Bus Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA (Bourns) | Same 180 V nominal, 600 W rating, but SMB package (surface-mount); lower parasitic inductance (~0.5 nH vs. ~2 nH for DO-15) | Preferred for high-frequency ESD protection on dense PCBs; not drop-in compatible with through-hole layouts | Select SMBJ180CA when board space is constrained and reflow assembly is used; verify pad thermal relief for 175°C operation. |
| 1.5KE180CA (ON Semiconductor) | Identical DO-204AC package and 180 V rating, but rated for 1500 W (10/1000 µs); higher clamping voltage (258 V vs. 246 V) | Better suited for extreme surge environments (e.g., telecom central office); overkill for standard automotive load dump | Choose 1.5KE180CA only if system-level testing requires >600 W margin; otherwise P6KE180CA offers tighter clamping and lower cost. |
Compared with SMBJ180CA and 1.5KE180CA, the P6KE180CA provides optimal balance of clamping performance, AEC-Q101 compliance, and through-hole manufacturability for cost-sensitive automotive and industrial power rail protection.

FAQ
What does the "CA" suffix indicate in P6KE180CA?
The "CA" suffix in P6KE180CA denotes a bidirectional configuration-meaning the device provides symmetrical clamping in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity. This makes P6KE180CA ideal for protecting AC-coupled interfaces like CAN, RS-485, or transformer-isolated power supplies where polarity reversal occurs.
Is P6KE180CA qualified for automotive applications?
Yes, P6KE180CA is AEC-Q101 qualified, having passed stress tests including temperature cycling, mechanical shock, and humidity bias life. It is explicitly listed in TSC's ordering matrix with "H" suffix variants (e.g., P6KE180CAH) for automotive-grade traceability-confirming its suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of P6KE180CA at rated surge current?
The maximum clamping voltage (VC) of P6KE180CA is 246 V at a peak pulse current (IPP) of 2.5 A, measured using the standardized 10/1000 µs waveform. This value ensures downstream components rated for ≤250 V absolute maximum will remain within safe operating limits during transient events.
Can P6KE180CA replace unidirectional TVS diodes like P6KE180A?
No-P6KE180CA is bidirectional and cannot directly replace unidirectional P6KE180A in circuits requiring polarity-specific clamping (e.g., DC power rail protection with explicit anode/cathode orientation). Substitution would require layout review to confirm symmetry and absence of DC bias that could forward-bias one junction unintentionally.
What packaging options are available for P6KE180CA?
P6KE180CA is supplied in DO-204AC (DO-15) axial package, available in 3,500-piece tape-and-reel (P6KE180CA) and 1,500-piece ammo box (P6KE180CA0G) formats. Tape-and-reel is optimized for automated through-hole insertion; ammo box supports manual or semi-automated prototyping and low-volume production.
