Product details
Overview
P6KE120ARLG 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 102 V working peak reverse voltage (VRWM), 120 V nominal breakdown voltage (VBR) at 1 mA test current, and clamps to ≤165 V at 3.6 A peak pulse current (IPP), making it suitable for overvoltage protection in industrial power supplies and communication interfaces.
For engineers reviewing the P6KE120ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin vs. operating DC voltage, clamping voltage headroom relative to protected IC absolute maximum ratings, surge current capability under 1 ms pulses, and Pb-free tape-and-reel packaging compliance for automated assembly.
Technical Context
The P6KE120ARLG operates as a silicon avalanche diode with fast <1 ns response time and low leakage (<5 µA at VRWM). Its clamping behavior is defined by a well-controlled breakdown knee at 120 V (±5%), with thermal resistance of 20 °C/W junction-to-lead enabling reliable 600 W nonrepetitive pulse handling at TL ≤ 25°C.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM). The device is rated for operation from −55°C to +150°C and exhibits a temperature coefficient of 0.107 %/°C for VBR, ensuring predictable voltage drift across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 102 V - Maximum continuous reverse voltage before significant leakage; must exceed system DC bus or signal swing. |
| VBR @ IT = 1 mA | 120 V (nominal), 114–126 V range - Avalanche onset voltage; defines minimum clamping threshold. |
| VC @ IPP = 3.6 A | ≤165 V - Maximum clamped voltage during 1 ms surge; determines protection margin for downstream ICs. |
| PPK | 600 W @ 1 ms - Peak pulse power rating; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IR @ VRWM | ≤5 µA - Low leakage ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| Response Time | <1 ns - Enables suppression before transient energy couples into sensitive analog/digital circuitry. |
| Package | Surmetic-40 axial lead (Case 017AA) - Standard through-hole mounting; Pb-free, RoHS-compliant, 4000/reel tape-and-reel format. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A | Surface-mount SMB package (vs. axial); same VRWM (102 V), VC = 165 V @ 3.6 A, but lower PPK = 600 W derated at TA. | Requires PCB redesign for SMT layout; better high-frequency performance due to lower parasitic inductance. | Select SMBJ120A when space-constrained designs or automated reflow assembly demand SMT form factor. |
| 1.5KE120A | Higher PPK = 1500 W, same VRWM/VBR/VC specs, but larger DO-201AD package and higher leakage (≤10 µA). | Used where higher surge margin is required (e.g., outdoor telecom cabinets), but consumes more board area. | Choose 1.5KE120A when system-level surge testing exceeds IEC 61000-4-5 Level 4 and axial footprint is acceptable. |
Compared with SMBJ120A, P6KE120ARLG offers proven axial-leaded reliability and UL 497B recognition in legacy through-hole designs; versus 1.5KE120A, it delivers identical clamping performance at half the peak power rating and smaller physical size-ideal for cost-optimized industrial power entry stages.

FAQ
What is the maximum clamping voltage of the P6KE120ARLG under surge conditions?
The P6KE120ARLG clamps to a maximum of 165 V when subjected to its rated peak pulse current of 3.6 A with a 1 ms waveform. This value is measured per Figure 4 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during transient events. Designers must ensure this clamping voltage remains below the absolute maximum ratings of downstream components. The P6KE120ARLG maintains this performance across its specified operating temperature range.
Does the P6KE120ARLG meet UL 497B certification for isolated loop protection?
Yes, the P6KE120ARLG is explicitly included in ON Semiconductor's UL 497B recognition under File #E210057 and Classification QVGQ2 for protector applications. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing-validating its suitability for telecom and industrial isolated interfaces. The P6KE120ARLG shares this qualification with the full P6KE6.8A–P6KE200A series as confirmed in the "UL RECOGNITION" section of the datasheet.
What is the temperature coefficient of VBR for the P6KE120ARLG?
The P6KE120ARLG has a maximum temperature coefficient of VBR of 0.107 %/°C, meaning its breakdown voltage increases by up to 0.107% per degree Celsius rise in junction temperature. This parameter is critical for predicting clamping behavior in high-temperature environments such as enclosed power supplies or motor drives. The coefficient is measured per standard test conditions and applies across the full −55°C to +150°C operating range of the P6KE120ARLG.
How does the P6KE120ARLG differ from the P6KE120A variant?
The P6KE120ARLG is the Pb-free, tape-and-reel packaged version of the P6KE120A, with identical electrical specifications including VRWM (102 V), VBR (120 V), VC (≤165 V), and PPK (600 W). The "RLG" suffix indicates RoHS-compliant construction and 4000-unit reel packaging optimized for automated assembly. The base P6KE120A uses standard SnPb leads and ships in 1000-unit boxes. Both share the same Surmetic-40 axial package and UL 497B recognition.
What is the steady-state power dissipation rating for the P6KE120ARLG?
The P6KE120ARLG has a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 25°C, derating linearly by 50 mW/°C above TL = 50°C. This rating applies only to continuous DC or low-frequency reverse bias conditions-not surge events. In normal operation, leakage current remains ≤5 µA at VRWM, resulting in negligible static power loss. The P6KE120ARLG relies on its 600 W peak pulse rating for transient energy absorption, not sustained power handling.
