Product details
Overview
P6KE47ARLG 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 40.2 V working peak reverse voltage (VRWM), 47.05 V nominal breakdown voltage (VBR) at 1 mA test current, 64.8 V maximum clamping voltage (VC) at 9.3 A peak pulse current (IPP), and <1 ns response time - deployed in power supply input protection, industrial control I/O lines, and medical equipment surge interfaces.
For engineers reviewing the P6KE47ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC bus voltage, VC margin relative to protected IC absolute maximum ratings, UL 497B certification for isolated loop compliance, and Pb-free tape-and-reel packaging for automated SMT assembly.
Technical Context
The P6KE47ARLG operates as a silicon avalanche diode with sharp reverse-breakdown knee and low dynamic impedance during transient events. Its clamping action begins at VBR = 44.7–49.4 V (min–max), sustains 600 W nonrepetitive peak power for 1 ms pulses, and exhibits <5 µA leakage at VRWM with temperature coefficient of 0.101 %/°C.
It is rated for −55 °C to +175 °C operating junction temperature, has 20 °C/W junction-to-lead thermal resistance, and supports forward surge current up to 100 A (8.3 ms half-sine). The device meets UL 497B for isolated loop circuit protection and carries ESD rating >16 kV per Human Body Model.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Power Dissipation | 600 W @ 1 ms pulse - handles high-energy surges without failure in AC line or DC bus protection |
| Working Peak Reverse Voltage (VRWM) | 40.2 V - sets minimum continuous operating voltage threshold before conduction begins |
| Breakdown Voltage (VBR) | 44.7–49.4 V @ 1 mA - defines precise avalanche onset range for predictable clamping initiation |
| Clamping Voltage (VC) | 64.8 V @ 9.3 A IPP - limits transient voltage seen by downstream components during surge |
| Response Time | <1 ns - ensures suppression activates before sensitive logic or analog circuitry is overstressed |
| Leakage Current | <5 µA @ VRWM - minimizes standby power loss and avoids false triggering in high-impedance nodes |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust handling immunity during board assembly and field service |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), void-free thermosetting epoxy body with corrosion-resistant, solderable leads. Cathode indicated by polarity band; mounting position unrestricted. Lead temperature limit: 230 °C at 1/16″ from case for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during reverse-biased clamping | Connected to ground or low-impedance return path to complete surge current loop |
| Cathode | High-voltage node connection point | Connected to protected line (e.g., DC input, signal trace) - polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - enables use in telecom, medical, and industrial safety-critical interfaces |
| Pb-Free Tape & Reel Packaging | RoHS-compliant P6KE47ARLG variant supplied in 4000-unit reels - optimized for automated pick-and-place assembly |
| Low Clamping Ratio | VC / VBR ≈ 1.38 - tight voltage margin between breakdown and clamping improves system-level overvoltage headroom |
| High Surge Robustness | Withstands 100 A forward surge (8.3 ms) - supports repeated lightning-induced transients in outdoor or industrial environments |
| Negligible Inductance Layout | Designed for minimal lead inductance - reduces overshoot when mounted close to protected ICs with short traces |
Applications
| AC/DC Power Supply Input Protection | Industrial PLC Digital I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45A | Surface-mount SMB package; 45 V VRWM; 600 W rating; lower clamping (70 V @ 8.6 A) | Requires PCB re-layout; better suited for space-constrained consumer electronics | Select when automated SMT assembly and board density outweigh axial-lead serviceability needs |
| 1.5KE47A | Same axial package but 1.5 kW peak power; higher IPP (32.4 A); larger case (DO-201AE) | Over-spec for most 600 W applications; higher cost and footprint | Choose only when legacy 1.5KE footprint compatibility or extreme surge margin is required |
Compared with SMBJ45A and 1.5KE47A, the P6KE47ARLG delivers optimal balance of proven axial reliability, UL 497B certification, Pb-free tape-and-reel readiness, and precise 40.2 V VRWM alignment with common 48 V DC systems - making it ideal for industrial and medical OEM production.

FAQ
What is the clamping voltage of the P6KE47ARLG under maximum surge conditions?
The P6KE47ARLG has a maximum clamping voltage (VC) of 64.8 V at 9.3 A peak pulse current (IPP), measured per the 1 ms exponential waveform defined in Figure 4 of the datasheet. This value ensures protected circuits remain below critical overvoltage thresholds during standardized surge events. The P6KE47ARLG maintains this performance across its full operating temperature range and after repeated stress cycles when applied within derating guidelines.
Is the P6KE47ARLG certified for safety-critical applications like medical equipment?
Yes, the P6KE47ARLG carries UL 497B recognition (File #E210057) for isolated loop circuit protection, validating its use in patient-connected and other safety-critical medical systems. This certification covers endurance, dielectric withstand, and discharge testing - exceeding basic flammability requirements. The P6KE47ARLG's UL listing applies directly to its construction and electrical behavior, not just packaging, supporting compliance in IEC 60601-1–aligned designs.
How does the P6KE47ARLG differ from the P6KE47A variant?
The P6KE47ARLG is the Pb-free, tape-and-reel packaged version of the P6KE47A, sharing identical electrical specifications, thermal ratings, and mechanical dimensions. The "RLG" suffix denotes RoHS-compliant plating and 4000-unit reel packaging optimized for automated assembly. The P6KE47A is supplied in 1000-unit boxes with standard SnPb leads. Both share the same Surmetic−40 axial package (Case 017AA) and UL 497B recognition.
Can the P6KE47ARLG be used in bidirectional signal lines?
No - the P6KE47ARLG is a unidirectional TVS diode, intended only for DC-biased or ground-referenced lines. For bidirectional protection (e.g., AC signal lines, RS-485), ON Semiconductor offers the P6KE47CA series. Using the P6KE47ARLG on an AC-coupled or floating line risks forward conduction during negative half-cycles, leading to overheating or failure. Always match device polarity to system bias architecture.
What is the maximum steady-state power dissipation for the P6KE47ARLG at 75°C lead temperature?
The P6KE47ARLG has a steady-state power dissipation (PD) rating of 5.0 W at TL ≤ 75°C with 3/8″ lead length, derating linearly above that temperature at 50 mW/°C. This rating applies only to continuous DC or low-frequency reverse-bias conditions - not transient suppression duty. Exceeding this limit risks thermal runaway; the P6KE47ARLG must be used within its specified thermal envelope, especially in enclosed or high-ambient environments.
