Product details
Overview
P6KE100ARL 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 85.5 V working peak reverse voltage (VRWM), 100 V breakdown voltage (VBR) at 1 mA test current, 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPP), and sub-1 ns response time - deployed in industrial power supplies, medical equipment, and communication interfaces to absorb ESD and lightning-induced surges.
For engineers reviewing the P6KE100ARL datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, UL 497B-certified surge performance, thermal derating curves, axial lead mounting guidance, and direct alternative part comparisons - all grounded in ON Semiconductor's Rev. 8 datasheet and official ordering information.
Technical Context
The P6KE100ARL operates as a silicon avalanche diode with sharp reverse-breakdown knee and low dynamic impedance during transient events. Its clamping action begins at VRWM = 85.5 V and fully engages at VBR = 100 V (min) / 105 V (max), limiting voltage across protected circuitry to ≤137 V under 4.4 A 1 ms pulse. Thermal design relies on junction-to-lead resistance of 20 °C/W and steady-state power dissipation of 5.0 W at TL ≤ 75°C.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM). The device exhibits a temperature coefficient of 0.106 %/°C for VBR and maintains <5 µA leakage above 10 V - enabling stable operation across −55°C to +175°C junction temperature range without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms non-repetitive pulse - sustains single high-energy transients like lightning-induced surges in AC/DC front-ends |
| Working Peak Reverse Voltage (VRWM) | 85.5 V - sets minimum operating voltage threshold before clamping initiates; matches 72–85 V nominal DC bus systems |
| Breakdown Voltage (VBR) | 100 V (nominal) @ 1 mA - defines precise avalanche onset point for predictable overvoltage triggering |
| Clamping Voltage (VC) | 137 V @ IPP = 4.4 A - limits maximum voltage seen by downstream ICs during surge, enabling 15–20 V design margin |
| Leakage Current (IR) | <5 µA @ VRWM - ensures negligible standby power loss and no interference with high-impedance sensing circuits |
| Response Time | <1 ns - enables suppression before fast-edge transients (e.g., ESD, relay bounce) propagate into sensitive logic |
| ESD Rating | Class 3 (>16 kV HBM) - exceeds IEC 61000-4-2 Level 4 requirements for robust system-level ESD immunity |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), cathode indicated by polarity band; leads are solderable per 230°C/10 s specification at 1/16″ from case; void-free thermosetting epoxy body rated for −55°C to +175°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node in unidirectional clamp configuration; completes current path during reverse avalanche |
| Cathode | High-side input terminal | Connected to protected line (e.g., +12 V rail); polarity band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | QVGV2 file #E210057 - certified for isolated loop circuit protection, including strike voltage, endurance, and dielectric withstand testing |
| Surge Robustness | 600 W peak power with 4.4 A IPP - handles 10/1000 µs waveform surges common in industrial I/O and telecom line cards |
| Thermal Stability | 20 °C/W RJL and 0.106 %/°C VBR tempco - supports reliable operation in enclosed enclosures without forced airflow |
| Low Capacitance | ~100 pF @ VRWM - minimizes signal distortion on data lines up to ~10 MHz; confirmed via Figure 3 capacitance vs. VBR curve |
| Pb-Free Option | P6KE100ARLG variant available - RoHS-compliant lead finish compatible with standard SnPb and lead-free reflow profiles |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Shielding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Surface-mount SMB package (3.5 × 4.6 mm), 600 W rating, VRWM = 85.5 V, VC = 137 V @ 4.4 A - identical electrical specs but different footprint and thermal path | Requires PCB redesign for SMT placement; better suited for high-density layouts where axial leads are impractical | Select SMBJ100A when board space is constrained and reflow assembly is used; verify thermal relief pad design for 5.0 W steady-state dissipation |
| 1.5KE100A | Higher peak power (1500 W), same VRWM/VC/VBR, axial lead but larger DO-201AD package - physically longer (9.5 mm vs. 7.6 mm) and heavier | Used where multi-pulse or repeated surge exposure demands higher energy absorption margin beyond single-event 600 W | Choose 1.5KE100A for mission-critical infrastructure (e.g., base station power) needing extended surge endurance; accept larger board footprint and higher cost |
Compared with P6KE100ARL, SMBJ100A offers identical clamping performance in compact SMT form but requires layout change and has lower thermal mass, while 1.5KE100A provides 2.5× higher single-pulse energy capacity in a larger axial package - making P6KE100ARL optimal for cost-sensitive, through-hole industrial designs balancing size, reliability, and surge margin.

FAQ
What is the maximum clamping voltage of the P6KE100ARL under surge conditions?
The P6KE100ARL has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current (IPP) of 4.4 A with a 1 ms waveform. This value is guaranteed per ON Semiconductor's datasheet Rev. 8 and represents the highest voltage the device allows across protected circuitry during transient suppression - critical for ensuring downstream components remain within safe operating voltage limits.
Is the P6KE100ARL RoHS compliant and lead-free?
Yes, the P6KE100ARL is RoHS compliant. Its "RL" suffix denotes tape-and-reel packaging, and the Pb-free version is designated P6KE100ARLG. Both variants meet JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and are compatible with standard lead-free reflow profiles, as confirmed in ON Semiconductor's packaging documentation and Pb-Free Strategy Reference Manual.
How does the P6KE100ARL differ from bidirectional TVS diodes like P6KE100CA?
The P6KE100ARL is unidirectional and functions only during reverse-biased transients, making it ideal for DC power rail protection where polarity is fixed. In contrast, P6KE100CA is bidirectional and clamps both positive and negative surges - suitable for AC lines or floating signal paths. Using P6KE100ARL in AC applications risks forward conduction and failure; always match polarity configuration to system topology.
What is the thermal resistance and steady-state power rating of the P6KE100ARL?
The P6KE100ARL has a junction-to-lead thermal resistance (RJL) of 20 °C/W and a steady-state power dissipation (PD) of 5.0 W at lead temperature (TL) ≤ 75°C. Derating is required above 75°C at 50 mW/°C, per Figure 5 in the datasheet - meaning at TL = 100°C, PD drops to 3.75 W. This defines safe continuous power handling in thermally constrained enclosures.
Does the P6KE100ARL require external series impedance for proper operation?
Yes, the P6KE100ARL requires an external current-limiting impedance (e.g., fuse, PTC, or resistor) in series with the protected line to prevent destructive sustained conduction during prolonged overvoltage. Without it, the device may enter thermal runaway if clamped voltage persists beyond its 1 ms pulse rating - especially critical in fault conditions like shorted downstream loads or AC line faults.
