Product details
Overview
P6KE11ARLG from ON Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode in axial-leaded Surmetic−40 package, designed for parallel clamping protection of DC power rails and signal lines. It features a 9.4 V working peak reverse voltage (VRWM), 15.6 V clamping voltage at 38 A peak pulse current (IPP), <1 ns response time, and UL 497B recognition for isolated loop circuit protection - deployed in industrial power supplies and medical equipment input stages.
For engineers reviewing the P6KE11ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating 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 SMT assembly.
Technical Context
The P6KE11ARLG operates as a silicon avalanche diode with controlled breakdown behavior, triggered when reverse voltage exceeds its 11.05 V nominal breakdown voltage (VBR) at 1 mA test current. Its low dynamic impedance ensures stable clamping during 600 W nonrepetitive transients per Figure 4 waveform (tp = 1 ms).
Thermal design relies on junction-to-lead resistance of 20 °C/W and steady-state power dissipation derated from 5.0 W at TL ≤ 75 °C. Polarity is marked by cathode band; mounting position is unrestricted, supporting through-hole placement in high-surge zones near connectors or AC/DC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.4 V - Maximum continuous reverse voltage before leakage exceeds 5 µA; sets minimum operating margin above system DC rail (e.g., 9 V supply). |
| VBR @ IT=1 mA | 10.5–11.6 V - Breakdown range defining turn-on threshold; ensures reliable conduction before downstream IC damage. |
| VC @ IPP=38 A | 15.6 V - Clamped voltage during full 600 W surge; must stay below protected device's absolute max rating (e.g., 16 V MCU I/O). |
| IPP | 38 A - Peak pulse current supported at 1 ms pulse width; validates immunity to IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges. |
| Response Time | <1 ns - Enables suppression before transient energy couples into sensitive analog or digital circuitry. |
| Leakage Current | <5 µA @ 9.4 V - Minimizes standby power loss in battery-backed or low-power systems. |
| UL Recognition | UL 497B (File E116110) - Certified for use in isolated telecom/data line protectors without additional safety certification burden. |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), 8.38–8.89 mm body length, 3.30–3.68 mm diameter, cathode indicated by colored band. Leads are solderable per 230 °C / 10 s specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during overvoltage events. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., +12 V rail); avalanche conduction initiates here when VRWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles IEC 61000-4-5 combination wave surges up to 1 kV open-circuit / 0.5 kA short-circuit without degradation. |
| ESD robustness Class 3 (>16 kV HBM) | Withstands handling and board-level ESD events without parameter shift or failure - critical for field-serviceable equipment. |
| Pb-free tape-and-reel (RLG suffix) | Complies with RoHS and JEDEC J-STD-020 reflow profiles; 4000 units per reel supports high-volume automated assembly. |
| Temperature coefficient of VBR | 0.075 %/°C - Predictable VBR drift over −55 to +175 °C operating range enables stable clamping in automotive under-hood environments. |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage stress on protected components while maintaining fast response - superior to generic Zener-based suppressors. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment EMI Filter Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Surface-mount SMB package (3.5 × 4.6 mm), 600 W rating, VRWM = 9.4 V, VC = 17.0 V @ 35.3 A | Higher clamping voltage (+1.4 V) and lower IPP (−2.7 A); requires PCB real estate optimization for SMT vs. axial leads | Select SMBJ11A when space-constrained designs demand SMT integration and thermal coupling to copper pour compensates for higher VC. |
| 1.5KE11A | Through-hole DO-201 package, 1500 W rating, VRWM = 9.4 V, VC = 16.5 V @ 91 A | Higher power handling but larger footprint (7.1 × 9.5 mm body); slower thermal recovery limits repetitive surge duty | Choose 1.5KE11A only for legacy designs requiring >600 W single-pulse immunity where board space permits larger axial package. |
Compared with SMBJ11A and 1.5KE11A, the P6KE11ARLG delivers optimal balance of compact axial form factor, UL 497B certification, and tight 15.6 V clamping - making it preferred for new industrial and medical designs prioritizing safety compliance and surge margin over raw power rating.

FAQ
What is the maximum clamping voltage of the P6KE11ARLG under standard surge conditions?
The P6KE11ARLG has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38 A with a 1 ms pulse width per Figure 4 in the datasheet. This value is measured under standardized nonrepetitive surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Does the P6KE11ARLG meet UL safety certification requirements?
Yes, the P6KE11ARLG carries UL 497B recognition (File E116110) for isolated loop circuit protection. This certification covers surge withstand, dielectric voltage-withstand, and endurance testing - confirming suitability for safety-critical applications such as medical equipment and telecom interfaces where regulatory approval is required.
How does the P6KE11ARLG differ from bidirectional TVS diodes like P6KE11CA?
The P6KE11ARLG is unidirectional and conducts only during negative transients relative to its cathode, making it ideal for DC rail protection. In contrast, P6KE11CA is bidirectional and clamps both polarities - used in AC lines or data lines with no defined polarity. Their VRWM, VBR, and VC values differ accordingly, and they are not interchangeable without circuit redesign.
What is the meaning of the 'RLG' suffix in P6KE11ARLG?
The 'RLG' suffix indicates that the P6KE11ARLG is supplied in Pb-free (RoHS-compliant) tape-and-reel packaging, with 4000 units per reel. The 'R' denotes tape-and-reel, 'L' specifies axial lead configuration, and 'G' confirms Pb-free construction - critical for automated assembly and environmental compliance programs.
Can the P6KE11ARLG be used in automotive under-hood applications?
The P6KE11ARLG supports an operating temperature range of −55 °C to +175 °C and has a VBR temperature coefficient of 0.075 %/°C, enabling stable clamping performance in under-hood environments. However, it is not AEC-Q200 qualified; for automotive safety-critical systems, AEC-qualified alternatives should be selected instead.
