Product details
Overview
P6KE180CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 180V nominal breakdown voltage (VBR min/max: 162V–198V), 146V standoff voltage (VWM), clamps to ≤258V at 2.4A peak surge current, and uses DO-204AC (DO-15) package with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE180CH datasheet, P6KE180CH pinout, P6KE180CH application, or P6KE180CH equivalent, key selection criteria include its 10/1000μs 600W surge rating, <1.0ps response time from 0V to VBR, low dynamic impedance, ≤1μA leakage above 10V, and AEC-Q101 qualification - all critical for robust ESD and load-dump protection in automotive ECUs and industrial power supplies.
Technical Context
The P6KE180CH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 162–198V breakdown range under 1mA test current. Its clamping action limits transient energy to ≤258V at 2.4A (10/1000μs waveform), enabling protection of downstream MOSFETs, controllers, and sensors against ISO 7637-2 load dump and IEC 61000-4-5 surges.
Thermal performance is defined by a 175°C maximum junction temperature and derating curve per Fig.2; mechanical construction uses UL 94V-0 molding compound, pure tin-plated leads compliant with J-STD-002, and meets JESD 201 Class 2 whisker resistance - confirming suitability for reflow and wave soldering in high-reliability assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 146 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12V/24V/48V systems. |
| VBR (min/max) | 162 V / 198 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 258 V @ 2.4 A - Clamped voltage during 10/1000μs surge; determines maximum stress on protected ICs or FETs. |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; supports automotive load-dump immunity up to ISO 7637-2 Pulse 5a. |
| IR @ VWM | <1 μA - Reverse leakage at 146 V; negligible power loss and no system bias error in high-impedance sensing circuits. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400 g mass; compatible with legacy through-hole assembly and automated taping. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance. Weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return; completes conduction path during transient clamp event. |
| Cathode | Protected line input | Connected to line being protected (e.g., battery rail, sensor supply); blocks normal operation, conducts during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS modules per stress test requirements. |
| 600W surge capability | Withstands 10/1000μs transients up to 2.4A without degradation - sufficient for ISO 7637-2 Pulse 5a (load dump) in 24V systems. |
| Fast response time | <1.0 ps from 0V to VBR - faster than most microsecond-scale transients, ensuring clamping initiates before protected ICs experience overstress. |
| Low dynamic impedance | Enables tight clamping voltage window (258V max) even at high surge currents, minimizing voltage overshoot on sensitive nodes. |
| UL recognition | UL File #E-326243 confirms flammability (UL 94V-0) and safety compliance for end-equipment certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Surface-mount SMB package; 180V VBR, 200W PPK rating (vs. 600W); lower clamping voltage (291V vs. 258V at rated current). | Designed for PCB space-constrained designs; not AEC-Q101 qualified; limited to lower-energy transients. | Select when board area is critical and surge threat level is below ISO 7637-2 Pulse 5a. |
| 1.5KE180A | Same DO-15 package; 180V VBR; 1500W PPK rating; higher clamping voltage (274V @ 5.5A); no AEC-Q101 qualification. | Higher-power industrial use cases only; lacks automotive qualification and tighter leakage spec (<1μA). | Select when higher single-pulse energy handling is required and AEC-Q101 is not mandated. |
Compared with SMBJ180A and 1.5KE180A, the P6KE180CH uniquely combines AEC-Q101 qualification, 600W surge rating in axial DO-15 form factor, and ultra-low leakage - making it the preferred choice for automotive and high-reliability 24V/48V power rail protection where qualification and proven field performance are mandatory.

FAQ
What is the maximum clamping voltage of the P6KE180CH under standard surge conditions?
The P6KE180CH clamps to a maximum of 258 V when subjected to a 10/1000 μs surge waveform at 2.4 A peak current (IPP), as specified in the Electrical Specifications table. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE180CH maintains this clamping performance across its full operating temperature range, supporting reliable protection in demanding environments.
Is the P6KE180CH suitable for automotive applications?
Yes, the P6KE180CH is AEC-Q101 qualified, explicitly certified for automotive use per the ordering code suffix "H". It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge endurance relevant to engine control units, body electronics, and ADAS subsystems. The P6KE180CH's 175°C TJ max rating and DO-204AC package with JESD 201 Class 2 whisker resistance further validate its suitability for under-hood and chassis-mounted automotive applications.
How does the P6KE180CH differ from the P6KE180A variant?
The P6KE180CH is the AEC-Q101 qualified version with "H" suffix, whereas P6KE180A is the commercial-grade variant without automotive qualification. Both share identical electrical parameters - 162–198V VBR, 146V VWM, 258V VC @ 2.4A - but only the P6KE180CH undergoes the full AEC-Q101 stress test suite. The P6KE180CH also carries green compound marking and is packed in tape-and-reel (3,500 pcs), distinguishing it from non-H variants in logistics and compliance documentation.
What is the standoff voltage (VWM) of the P6KE180CH and why does it matter?
The P6KE180CH has a standoff voltage (VWM) of 146 V, meaning it remains non-conductive up to this reverse voltage during normal operation. This parameter ensures no power loss or signal distortion occurs under steady-state conditions while still allowing rapid avalanche conduction when transients exceed the breakdown threshold. For a 24V automotive system with worst-case ripple and tolerance, the 146V VWM provides ample margin against false triggering while preserving protection integrity.
Can the P6KE180CH be used in bidirectional configurations?
No, the P6KE180CH is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its cathode-band marking and single-diode configuration. Bidirectional operation requires parts like P6KE180C or P6KE180CA, which contain two opposing diodes in series. Using the P6KE180CH in reverse-biased AC applications would result in forward conduction and failure; always verify polarity alignment in circuit layout for the P6KE180CH.
