Product details
Overview
P6KE180H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in power supply input stages and automotive ECU protection circuits. It features a 180V nominal breakdown voltage (VBR min/max = 162V/198V), 146V standoff voltage (VWM), 2.4A peak surge current (IPP), 258V maximum clamping voltage (VC) at IPP, and AEC-Q101 qualification for automotive under-hood applications.
For engineers reviewing the P6KE180H datasheet, P6KE180H pinout, P6KE180H application, or P6KE180H equivalent, key selection criteria include clamping voltage margin relative to system rail, surge current capability under 10/1000μs waveform, junction temperature derating above 25°C, and AEC-Q101 compliance status for automotive deployment.
Technical Context
The P6KE180H operates as a silicon avalanche diode with unidirectional polarity, activated only during reverse-biased overvoltage events. Its low dynamic impedance ensures rapid voltage clamping within <1.0ps response time from 0V to VBR, while maintaining <1μA reverse leakage at 10V above VWM.
It is rated for non-repetitive 600W peak pulse power at 10/1000μs waveform, with thermal derating above 25°C per Fig.2 and maximum junction temperature of +175°C. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 146 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 162 V / 198 V - Breakdown initiates within this range at 1 mA test current; defines clamping onset threshold |
| VC @ IPP | 258 V - Clamped voltage seen by protected circuit when subjected to 2.4 A 10/1000μs surge |
| PPK | 600 W - Peak pulse power handling capability under standard 10/1000μs transient waveform |

Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking on one end; anode and cathode terminals are non-polarized in layout but functionally asymmetric-cathode is marked side, anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential node (e.g., ground or return); conducts during forward surge (IFSM = 100 A) |
| Cathode | Clamping reference node | Connected to protected line (e.g., 12V/24V rail); avalanche breakdown occurs between cathode and anode during overvoltage |

| 600W surge rating | Withstands ISO 7637-2 Pulse 1, 2a, 3a/b transients and IEC 61000-4-5 Level 3 surges without degradation |
| 258V clamping at 2.4A | Provides ≥15% margin above 220V DC bus in 24V automotive systems, preventing downstream IC latch-up or damage |
| <1.0ps response time | Clamps faster than most microcontroller I/O pin ESD structures, enabling effective pre-IC protection |
| UL 94V-0 flammability | Molding compound resists ignition and flame propagation during sustained overvoltage fault conditions |
Applications
| Automotive Power Rail Protection | Industrial SMPS Input Stage |
|---|---|
Use Scenario: 12V/24V battery-connected ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping device placed directly across input rail before DC-DC converter or LDO regulator. Use Value: Limits transient voltage to ≤258V, protecting downstream 36V-rated MOSFETs and 32V-input PMICs from destructive overvoltage. | Use Scenario: AC-DC front-end rectifier output in industrial 24V/48V power supplies subject to lightning-induced surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor to clamp differential-mode transients before filtering stage. Use Value: Absorbs 600W pulses without failure, preserving capacitor lifetime and preventing secondary failures in downstream regulators. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
Use Scenario: Constant-current LED drivers in street lighting exposed to induced surges from nearby switching loads. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LED string anode and chassis ground to suppress positive-going transients. Use Value: Clamps 10/1000μs surges to 258V, ensuring LED driver ICs with 300V absolute max ratings remain within safe operating area. | Use Scenario: Low-voltage DC power feed lines (e.g., PoE midspan) entering telecom cabinets with poor grounding. IC Role / Device Role / Timing Role: Standoff protection device on 48V DC input rail upstream of DC-DC isolation stage. Use Value: Provides robust 600W surge immunity while maintaining <1μA leakage at 146V, minimizing standby power loss. |
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 SMAJ180A | Same 180V nominal, 600W rating, DO-214AC (SMA) surface-mount package; 255V VC @ 2.4A | Requires PCB rework for SMT vs. through-hole; better thermal performance in high-density layouts | Select for space-constrained designs where automated assembly and thermal management outweigh manual soldering needs |
| ON Semiconductor 1.5KE180A | Same 180V rating, 1500W peak power, DO-201AD package; 260V VC @ 5.8A; no AEC-Q101 qualification | Higher surge capacity but larger footprint; not validated for automotive temperature cycling or humidity testing | Select for industrial power supplies requiring higher single-pulse energy absorption without automotive qualification |
Compared with SMAJ180A and 1.5KE180A, the P6KE180H offers AEC-Q101 validation and DO-15 through-hole compatibility for legacy automotive harness interfaces, while delivering tighter clamping (258V) than the 1.5KE180A (260V) at lower surge current-making it optimal for cost-sensitive, high-reliability 24V rail protection.

FAQ
What is the clamping voltage of P6KE180H at its rated surge current?
The P6KE180H has a maximum clamping voltage (VC) of 258 V when subjected to its rated peak pulse current (IPP) of 2.4 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry sees no more than 258 V during a defined surge event, providing critical margin for 200–240 V-rated components downstream of the P6KE180H.
Is P6KE180H suitable for bidirectional transient protection?
No, the P6KE180H is a unidirectional TVS diode intended for DC circuits with defined polarity. It clamps only reverse-biased overvoltages and conducts forward current up to 100 A (IFSM). For bidirectional protection-such as AC lines or data buses-P6KE180CA or P6KE180A variants must be used, as explicitly stated in the "Devices for Bipolar Applications" section of the datasheet.
Does P6KE180H meet RoHS and halogen-free requirements?
Yes, the P6KE180H is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its pure tin-plated leads satisfy J-STD-002 solderability standards. These material qualifications are confirmed in the Mechanical Data and Features sections of the official Taiwan Semiconductor P6KE series datasheet (Version P2203).
What is the maximum operating junction temperature for P6KE180H?
The P6KE180H has a maximum junction temperature (TJ max) of +175°C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating of peak pulse power begins above TA = 25°C per the Pulse Derating Curve (Fig.2), requiring thermal design consideration for sustained high-ambient applications.
How does the AEC-Q101 qualification of P6KE180H impact its use in automotive designs?
The AEC-Q101 qualification of P6KE180H validates its reliability for automotive electronics, including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock testing. Unlike standard industrial TVS diodes, the P6KE180H is approved for use in engine control modules, body control units, and ADAS power domains where failure could compromise functional safety-making it a drop-in replacement for legacy AEC-Q101-compliant protection schemes without additional qualification effort.
