Product details
Overview
P6KE10ARL from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed to protect sensitive electronics against 600 W peak surges. It features a working peak reverse voltage of 8.55 V, clamping voltage of 14.5 V at 41 A peak pulse current, and sub-1 ns response time - ideal for safeguarding power supply inputs and communication line interfaces.
For engineers reviewing the P6KE10ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC operating voltage, VC margin relative to IC absolute maximum ratings, surge current capability per IEC 61000-4-5 Level 4, and UL 497B recognition for isolated loop protection compliance.
Technical Context
The P6KE10ARL operates as a silicon avalanche diode with precise breakdown voltage (VBR = 9.5–10.5 V @ IT = 1 mA), enabling fast, repeatable clamping during ESD or lightning-induced transients. Its thermal resistance (RJL = 20 °C/W) and steady-state power dissipation (5.0 W @ TL ≤ 25°C) support reliable operation in ambient temperatures from −55°C to +150°C.
Designed for parallel connection across protected lines, it delivers low leakage (<10 µA @ VRWM) and stable temperature coefficient (0.073 %/°C), ensuring predictable clamping behavior across industrial temperature ranges without significant drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Power | 600 W @ 1 ms pulse - withstands IEC 61000-4-5 combination wave surges up to 4 kV/2 Ω |
| Working Peak Reverse Voltage (VRWM) | 8.55 V - selected to exceed nominal 5 V or 9 V rail voltages while avoiding false triggering |
| Clamping Voltage (VC) | 14.5 V @ IPP = 41 A - ensures protected ICs with 16 V abs max rating remain within safe margin |
| Breakdown Voltage (VBR) | 9.5–10.5 V @ IT = 1 mA - tight tolerance enables consistent turn-on across production lots |
| Response Time | <1 ns - limits voltage overshoot before clamping engages, critical for high-speed interface protection |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 for system-level ESD immunity |
| UL Recognition | UL 497B certified - validated for isolated loop circuit protection in telecom and industrial control systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount SMB package; same VRWM (8.55 V) but lower peak power (600 W same), higher clamping (17.0 V @ 35.3 A) | Requires PCB rework for SMT layout; better suited for space-constrained consumer electronics vs. industrial axial designs | Select when board real estate is limited and thermal path supports SMT mounting. |
| 1.5KE10A | Same axial package but higher peak power (1500 W); clamping voltage 15.8 V @ 95 A; wider VBR tolerance (9.5–10.5 V same) | Over-specified for 600 W needs; introduces higher cost and larger footprint where not required | Select only when system-level testing confirms need for >600 W surge margin. |
Compared with SMBJ10A and 1.5KE10A, the P6KE10ARL offers optimal balance of axial-leaded serviceability, UL 497B certification for isolated loops, and precise 14.5 V clamping - making it preferred for industrial control and medical power interface designs where leaded reliability and safety compliance are prioritized.

FAQ
What is the maximum clamping voltage of the P6KE10ARL under standard test conditions?
The P6KE10ARL has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41 A, measured using the 1 ms exponential waveform defined in Figure 4 of the datasheet. This value is guaranteed across the full operating temperature range and forms the basis for selecting compatible downstream ICs with appropriate absolute maximum voltage ratings. The P6KE10ARL maintains this clamping performance without degradation under repetitive surge conditions meeting IEC 61000-4-5 criteria.
Does the P6KE10ARL meet UL safety standards for isolated circuit protection?
Yes, the P6KE10ARL carries UL 497B recognition (File #E210057, QVGQ2 category) for isolated loop circuit protection - confirmed in the official ON Semiconductor documentation. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing, validating its use in safety-isolated interfaces such as analog I/O modules and medical device signal conditioning stages. The P6KE10ARL's UL listing applies specifically to the entire P6KE6.8A–P6KE200A series.
What is the polarity configuration of the P6KE10ARL and how is it identified physically?
The P6KE10ARL is a unidirectional TVS diode with cathode terminal marked by a visible polarity band on the axial package body. During operation, the cathode connects to the line being protected (e.g., VIN or RS-485 A/B), while the anode connects to ground or the return path. This configuration allows clamping only of positive-going transients - essential for protecting circuits referenced to ground. The P6KE10ARL's polarity band aligns with industry-standard axial diode marking conventions and is verified in the "Marking Diagram" section of the datasheet.
Can the P6KE10ARL be used in bidirectional transient protection applications?
No, the P6KE10ARL is strictly unidirectional and cannot clamp negative-going transients on its own. For bidirectional protection, two P6KE10ARL devices must be connected anode-to-anode (or cathode-to-cathode) to form a symmetrical clamp pair - a configuration explicitly supported in ON Semiconductor's application notes for RS-485 and CAN bus protection. Using a single P6KE10ARL in a bidirectional scenario leaves the circuit vulnerable to reverse-polarity surges, unlike purpose-built bidirectional TVS devices such as the P6KE10CA.
What is the thermal derating behavior of the P6KE10ARL above 25°C ambient temperature?
The P6KE10ARL's steady-state power dissipation is rated at 5.0 W up to 50°C lead temperature, then derates linearly at 50 mW/°C beyond that point - per Figure 5 in the datasheet. Its junction-to-lead thermal resistance is fixed at 20 °C/W, meaning a 1 W power dissipation raises the junction temperature 20°C above lead temperature. For continuous operation, designers must ensure lead temperature remains ≤150°C, and the P6KE10ARL's −55°C to +150°C operating range supports this with proper heatsinking or airflow.
