Product details
Overview
P6KE68ARLG 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 58.1 V working peak reverse voltage (VRWM), 68 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤92 V at 6.5 A peak pulse current - ideal for protecting power supply inputs and communication line interfaces against ESD and lightning-induced surges.
For engineers reviewing the P6KE68ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. system operating voltage, surge current capability under 1 ms pulses, UL 497B recognition for isolated loop protection, and Pb-free tape-and-reel packaging compliance for automated assembly.
Technical Context
The P6KE68ARLG operates as a silicon avalanche diode with fast turn-on response (<1 ns) and low dynamic impedance during transient events. Its unidirectional polarity enables DC-biased protection paths without reverse conduction during normal operation.
It delivers 600 W nonrepetitive peak pulse power per 1 ms waveform (Figure 4), with thermal derating above 75°C lead temperature and steady-state dissipation limited to 5.0 W. The device meets Class 3 ESD immunity (>16 kV HBM) and is UL 497B recognized for isolated loop circuit protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 58.1 V - maximum continuous reverse voltage before clamping begins; must exceed system DC/peak operating voltage |
| VBR @ IT=1 mA | 68 V (min–max: 64.6–71.4 V) - precise avalanche onset threshold enabling predictable overvoltage triggering |
| VC @ IPP=6.5 A | ≤92 V - clamped voltage during 1 ms surge; defines worst-case stress on protected downstream components |
| IPP | 6.5 A - peak pulse current supported at rated clamping voltage; determines surge energy handling (600 W) |
| IR @ VRWM | ≤5 µA - ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Response Time | <1 ns - enables suppression before transient energy couples into sensitive ICs or analog front-ends |
| UL Recognition | UL 497B (File #E210057) - certified for use in isolated loop protection systems including telecom and industrial I/O |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), cathode indicated by band; leads are solderable at 230°C for 10 seconds 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 in unidirectional clamp configuration |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., VIN, RS-485 bus); polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles high-energy transients (e.g., lightning-induced surges on AC mains or telecom lines) without failure |
| Clamp voltage ≤92 V at 6.5 A | Provides safe margin below typical 100 V absolute maximum ratings of industrial power controllers and interface ICs |
| UL 497B certification | Validates suitability for safety-critical isolated loop applications including medical equipment and process control I/O |
| ESD rating >16 kV HBM | Protects against human-body-model electrostatic discharge events common in manufacturing and field service environments |
| Pb-free tape-and-reel (RLG) | Enables RoHS-compliant automated SMT placement with 4000-unit reels for high-volume production |
Applications
| Industrial Power Supply Input Protection | RS-485/422 Communication Line Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Surface-mount SMB package; 64 V VRWM; 100 W peak power; lower surge capacity than P6KE68ARLG | Better suited for space-constrained PCBs but requires layout redesign; lacks UL 497B recognition | Select when board area is critical and surge levels are ≤100 W; verify clamping margin against system voltage |
| 1.5KE68A | Same axial package; identical 68 V VBR; 1500 W peak power; higher VC (118 V) and larger physical size | Higher energy handling for severe industrial environments; less precise clamping due to higher VC | Choose for legacy designs needing higher surge robustness where 118 V clamping is acceptable |
Compared with SMBJ64A and 1.5KE68A, the P6KE68ARLG offers optimal balance of UL-certified reliability, 600 W surge capability, and tight 92 V clamping - making it preferred for cost-sensitive, safety-compliant industrial and medical power interface protection.

FAQ
What is the clamping voltage of the P6KE68ARLG and how does it relate to system protection?
The P6KE68ARLG has a maximum clamping voltage (VC) of 92 V at 6.5 A peak pulse current. This value defines the highest voltage imposed on protected circuitry during a transient event. For reliable protection, the system's absolute maximum voltage rating must exceed 92 V - for example, selecting a 100 V-rated regulator ensures margin. The P6KE68ARLG's tight VBR tolerance (64.6–71.4 V) and low dynamic impedance ensure consistent clamping behavior across units and temperatures.
Is the P6KE68ARLG RoHS compliant and what does the 'RLG' suffix indicate?
Yes, the P6KE68ARLG is RoHS compliant and Pb-free. The 'RLG' suffix specifically denotes an axial-leaded Surmetic−40 package supplied in tape-and-reel format (4000 units per reel) with lead finish meeting JEDEC J-STD-020 moisture sensitivity level 1 requirements. This configuration supports automated pick-and-place assembly while maintaining full electrical and thermal specifications of the standard P6KE68A variant.
Does the P6KE68ARLG require a series impedance for proper operation?
Yes - a current-limiting impedance (e.g., fuse, PTC, or resistor) must be placed in series with the P6KE68ARLG to prevent destructive follow-on current during sustained overvoltage conditions. Without such impedance, the device may enter thermal runaway if exposed to voltages exceeding VRWM for extended periods. Typical designs use a 1–10 Ω resistor or polyfuse upstream to limit fault current while preserving fast transient response.
How does the UL 497B recognition benefit designs using the P6KE68ARLG?
The UL 497B recognition confirms that the P6KE68ARLG meets rigorous safety requirements for protectors used in isolated loop circuits - including dielectric withstand, endurance conditioning, and strike voltage breakdown tests. This eliminates the need for additional third-party certification testing when used in medical, industrial, or telecom equipment requiring compliance with IEC 62368-1 or UL 62368-1, accelerating time-to-market for safety-critical applications.
Can the P6KE68ARLG be used in bidirectional protection configurations?
No - the P6KE68ARLG is strictly unidirectional and must not be used for bidirectional surge suppression. For AC or dual-polarity signal lines, ON Semiconductor offers the P6KE68CA series (bidirectional variant). Using the P6KE68ARLG in reverse-biased mode risks premature breakdown and unreliable clamping; its design assumes cathode-to-line, anode-to-ground orientation only.
