Product details
Overview
P6KE11AG 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 sensitive electronics. It features a 9.4 V working peak reverse voltage (VRWM), 15.6 V maximum clamping voltage at 38 A peak pulse current (IPP), and <1 ns response time-ideal for safeguarding power supply inputs and communication line interfaces against ESD and lightning-induced surges.
For engineers reviewing the P6KE11AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating DC voltage, VC/IPP trade-off for system-level surge immunity, UL 497B certification for isolated loop protection, and Pb-free axial-lead compatibility with through-hole reflow or hand-soldering processes.
Technical Context
The P6KE11AG operates as a silicon avalanche diode, entering breakdown conduction when transient voltage exceeds its specified VBR range (10.5–11.6 V @ 1 mA). Its clamping action limits downstream voltage to ≤15.6 V during 1 ms 38 A pulses, with thermal resistance of 20 °C/W enabling reliable power dissipation under repetitive surge conditions.
Designed for unidirectional protection only, it exhibits low leakage (<5 µA @ 9.4 V), a temperature coefficient of 0.075 %/°C for VBR drift control, and meets Class 3 ESD immunity (>16 kV HBM)-critical for industrial equipment and medical device front-end circuits where polarity-sensitive DC rails require robust overvoltage suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 9.4 V - Maximum continuous reverse voltage before clamping begins; must exceed circuit's peak operating voltage by ≥10%. |
| VBR (min/typ/max) | 10.5 / 11.05 / 11.6 V @ 1 mA - Tight breakdown tolerance ensures predictable turn-on across temperature and unit variation. |
| VC @ IPP | 15.6 V @ 38 A - Clamped voltage during worst-case 1 ms surge; defines maximum stress on protected ICs or regulators. |
| PPK | 600 W @ 1 ms - Peak pulse power rating determines survivability against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω). |
| Response Time | <1 ns - Enables suppression before transient energy couples into downstream logic or analog circuitry. |
| Leakage Current | <5 µA @ VRWM - Negligible standby power loss in battery-powered or high-impedance sensing nodes. |
| UL Recognition | UL 497B (QVGV2) - Certified for isolated loop circuit protection, validating reliability in telecom and process control safety systems. |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), cathode indicated by band; leads are solderable at 230 °C for 10 s at 1/16″ from case. Mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during positive transients. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., +12 V rail); polarity band identifies this terminal for correct orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV without degradation. |
| UL 497B recognition | Validated for use in certified isolated loop protection circuits-reduces safety certification effort in industrial controllers. |
| ESD rating >16 kV HBM | Eliminates need for additional ESD diodes in front-panel or connector interfaces exposed to human handling. |
| Pb-free axial package | Complies with RoHS Directive 2011/65/EU and supports lead-free reflow profiles without lead melting risk. |
| Temperature coefficient 0.075 %/°C | Ensures VBR shift remains within ±5% over −55 °C to +175 °C junction range-critical for automotive under-hood designs. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment Signal Line Guarding |

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; same VRWM (9.4 V) and VC (15.6 V), but lower PPK (600 W vs. 600 W), higher IPP (38 A vs. 38 A), identical VBR range. | Requires PCB redesign for SMT placement; better high-frequency response due to lower parasitic inductance. | Select SMBJ11A when board space is constrained and automated assembly is preferred over through-hole mounting. |
| 1.5KE11A | Same axial package and electrical specs, but rated for 1.5 kW peak power (1 ms); larger case size (DO-201AD vs. DO-15/Surmetic−40). | Higher surge margin for utility-grade equipment; incompatible footprint-requires mechanical redesign. | Choose 1.5KE11A only when legacy 1.5 kW surge standards apply and board layout allows larger body dimensions. |
Compared with SMBJ11A and 1.5KE11A, the P6KE11AG delivers identical clamping performance in a compact, UL-recognized axial package optimized for manual assembly, cost-sensitive industrial power supplies, and applications requiring proven field reliability over 20+ years of deployment.

FAQ
What is the maximum clamping voltage of the P6KE11AG under surge conditions?
The P6KE11AG has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current (IPP) of 38 A with a 1 ms waveform. This value is guaranteed across manufacturing lots and validated per Figure 4 in the official datasheet. The P6KE11AG maintains this clamping performance up to +175 °C junction temperature, making it suitable for under-hood automotive applications where thermal derating must be minimized.
Does the P6KE11AG meet UL safety standards for isolated circuit protection?
Yes, the P6KE11AG carries UL 497B recognition (File #E116110, Category QVGV2) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown tests-validating its use in telecom, industrial control, and medical isolation barriers. The P6KE11AG's UL listing applies specifically to the "G" suffix Pb-free variant and is documented in the September 2005 Rev. 7 datasheet.
Can the P6KE11AG be used in bidirectional surge protection circuits?
No, the P6KE11AG is a unidirectional TVS diode and must not be used for bidirectional protection. It conducts only during positive transients applied to its cathode relative to anode. For AC or dual-polarity lines, a bidirectional variant such as P6KE11CA-or two P6KE11AG devices in series opposition-is required. Using the P6KE11AG in reverse-biased configuration risks permanent failure due to lack of symmetric breakdown capability.
What is the thermal resistance from junction to lead for the P6KE11AG?
The P6KE11AG has a thermal resistance (RJL) of 20 °C/W from junction to lead, measured with 3/8″ lead length at TL ≤ 75 °C. This value enables direct thermal coupling to copper pour or heatsinking leads in high-surge applications. When mounted with shorter leads or on thermally enhanced PCBs, the effective RθJA improves, allowing higher average surge repetition rates without exceeding the +175 °C maximum junction temperature limit.
Is the P6KE11AG compatible with lead-free soldering processes?
Yes, the "G" suffix in P6KE11AG explicitly denotes compliance with Pb-free packaging requirements. Its leads are solderable at 230 °C for 10 seconds at 1/16″ from the case, aligning with J-STD-020 moisture sensitivity level (MSL) 1 handling and standard lead-free reflow profiles. The P6KE11AG's Surmetic−40 epoxy body is qualified for repeated thermal cycling without delamination, ensuring long-term reliability in RoHS-compliant manufacturing.
