Product details
Overview
P6KE180ARL from ON Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode in axial-leaded Surmetic−40 package, designed for parallel clamping of voltage-sensitive circuits. It features a 154 V working peak reverse voltage (VRWM), 180 V breakdown voltage (VBR) at 1 mA test current, 246 V maximum clamping voltage at 2.4 A peak pulse current, and sub-1 ns response time-ideal for protecting power supplies and industrial control inputs against ESD and lightning-induced surges.
For engineers reviewing the P6KE180ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC bus voltage, clamping voltage margin relative to protected IC absolute maximum ratings, UL 497B certification for isolated loop protection, and axial-leaded tape-and-reel packaging for automated assembly.
Technical Context
The P6KE180ARL operates as a silicon avalanche diode with precisely controlled reverse-biased breakdown behavior. Its clamping action begins at VBR = 171–189 V (min/typ/max), limiting transient overvoltage to ≤246 V at IPP = 2.4 A under 1 ms 10/1000 µs waveform conditions per Figure 4.
Thermal design relies on junction-to-lead thermal resistance (RJL = 20 °C/W) and steady-state power dissipation derating above 75 °C ambient. The device exhibits low leakage (<5 µA @ VRWM) and a temperature coefficient of 0.108 %/°C for VBR stability across −55 to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - withstands high-energy transients without failure |
| Working Peak Reverse Voltage | 154 V - sets minimum DC/continuous AC voltage threshold before conduction |
| Breakdown Voltage (VBR) | 171–189 V @ 1 mA - defines precise avalanche onset for predictable clamping |
| Maximum Clamping Voltage (VC) | 246 V @ 2.4 A - limits protected circuit voltage during surge event |
| Leakage Current | <5 µA @ 154 V - ensures minimal standby power loss and signal integrity |
| Response Time | <1 ns - enables suppression before sensitive components experience overvoltage |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 immunity requirements |

Applications
| Industrial Power Supply Input Protection | Medical Equipment Surge Suppression |
|---|---|
Use Scenario: 24–48 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between input rail and chassis ground to clamp positive-going surges. Use Value: Limits transient voltage to ≤246 V, preserving downstream DC-DC converter input rating (typically 36 V abs max) while surviving 600 W pulses. |
Use Scenario: Patient-connected sensor interface in diagnostic imaging equipment requiring IEC 60601-1 compliance and isolation barrier integrity. IC Role / Device Role / Timing Role: Secondary-side transient protector on isolated analog front-end supply rail. Use Value: UL 497B recognition validates use in isolated loop circuits; <1 ns response prevents overshoot from compromising galvanic isolation. |
| Telecom Line Card Protection | Automotive Body Control Module (BCM) Inputs |
Use Scenario: Ethernet PHY interface on telecom base station line card subjected to lightning-induced common-mode surges on twisted-pair lines. IC Role / Device Role / Timing Role: Primary-level unidirectional clamping device on DC bias rail feeding PoE injector circuitry. Use Value: 154 V VRWM matches typical 48 V PoE system operating voltage; 246 V VC ensures PHY ICs (e.g., MAX24106) remain within safe operating area. |
Use Scenario: 12 V battery-supplied input of BCM microcontroller GPIO monitoring door lock actuator status. IC Role / Device Role / Timing Role: Low-leakage (≤5 µA) TVS on switched 12 V sense line to prevent latch-up during load dump events. Use Value: Maintains signal fidelity during normal operation while clamping 100 V/100 ms load dump transients to <246 V - well below MCU IO absolute max rating. |
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 (vs. axial P6KE); same 180 V VBR but lower 600 W rating derated to 400 W at 25 °C ambient | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics vs. industrial through-hole assemblies | Select when board space is limited and automated pick-and-place is available; verify thermal pad layout for equivalent RJL performance |
| 1.5KE180A | Same axial package but higher 1500 W peak power rating; larger case size (Case 017AB) and higher clamping voltage (259 V @ 5.8 A) | Used where higher surge energy (e.g., outdoor telecom cabinets) demands greater single-pulse robustness | Choose only if system-level testing confirms need for >600 W capability; avoid if 246 V clamping margin is critical for downstream IC survival |
Compared with SMBJ180A and 1.5KE180A, the P6KE180ARL delivers optimal balance of axial-leaded manufacturability, UL 497B certification for isolated systems, and tight 246 V clamping-making it preferred for cost-sensitive industrial power supplies where leaded assembly and safety compliance are mandatory.

FAQ
What is the maximum clamping voltage of the P6KE180ARL under standard surge conditions?
The P6KE180ARL has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.4 A, measured using the 10/1000 µs waveform defined in Figure 4 of the datasheet. This value is guaranteed across the full operating temperature range and ensures protected circuitry remains within safe voltage limits during transient events.
Does the P6KE180ARL meet UL safety standards for isolated circuit protection?
Yes, the P6KE180ARL carries UL 497B recognition under File #E210057 for protector classification (QVGV2), validating its suitability in isolated loop circuits such as medical sensor interfaces and telecom power feeds. This certification covers strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing - exceeding basic flammability-only approvals.
What is the polarity marking convention for the P6KE180ARL?
The P6KE180ARL uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential side (e.g., protected line), while the unbanded end is the anode and connects to ground or return. This unidirectional configuration ensures conduction only during positive transients relative to ground.
Can the P6KE180ARL be used in surface-mount designs?
No - the P6KE180ARL is exclusively offered in axial-leaded Surmetic−40 package (Case 017AA) for through-hole mounting. For surface-mount alternatives, consider the SMBJ180A or SMCJ180A families, which share similar electrical characteristics but require different PCB footprints and thermal management strategies.
What is the leakage current specification for the P6KE180ARL at its working voltage?
The P6KE180ARL specifies a maximum reverse leakage current (IR) of 5 µA when biased at its working peak reverse voltage (VRWM) of 154 V. This low leakage ensures minimal power loss and signal interference in always-on monitoring circuits, such as those found in industrial process controllers and battery-backed systems.
