Product details
Overview
P6KE110ARL 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 94 V working peak reverse voltage (VRWM), 110.5 V minimum breakdown voltage (VBR) at 1 mA test current, 152 V maximum clamping voltage (VC) at 4 A peak pulse current (IPP), and sub-1 ns response time - deployed in industrial power supplies and medical equipment input stages.
For engineers reviewing the P6KE110ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating voltage, VC vs. protected IC absolute maximum rating, surge current handling (IPP = 4 A), UL 497B recognition for isolated loop protection, and Pb-free tape-and-reel packaging (4000 units/reel).
Technical Context
The P6KE110ARL operates as a silicon avalanche diode, entering conduction when reverse voltage exceeds its specified VBR (110.5–116 V), clamping transients to ≤152 V at 4 A IPP. Its thermal resistance (RJL = 20 °C/W) and steady-state power dissipation (5.0 W @ TL ≤ 75°C) define safe continuous operation limits under sustained leakage or low-duty-cycle surges.
It complies with UL 497B for isolated loop circuit protection and exhibits ESD robustness >16 kV per Human Body Model. The device's fast response (<1 ns) and low capacitance (typ. <100 pF at VRWM) minimize overshoot in high-speed protection circuits when mounted with short leads near vulnerable nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 94 V - Maximum continuous reverse voltage before significant leakage; must exceed system DC rail or peak AC voltage. |
| VBR (min) | 110.5 V @ IT = 1 mA - Ensures reliable turn-on above normal operating voltage with margin against tolerance drift. |
| VC (max) | 152 V @ IPP = 4 A - Defines worst-case clamped voltage seen by downstream components during surge events. |
| PPK | 600 W @ 1 ms - Peak single-pulse energy absorption capability per Figure 4 waveform (10/1000 µs equivalent). |
| IR (max) | 5 µA @ VRWM - Low leakage preserves efficiency in high-impedance bias or sensing circuits. |
| Response Time | <1 ns - Enables suppression of fast-rising ESD and lightning-induced transients before damage occurs. |
| UL Recognition | UL 497B (File #E116110) - Validated for use in safety-critical isolated communication and control loops. |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), cathode indicated by polarity band. Leads are solderable, corrosion-resistant, rated for 230°C @ 1/16″ from case for 10 s. Mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-voltage reference; completes clamping path during reverse transient. |
| Cathode | High-side connection point | 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 | Handles IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without degradation when properly heatsinked. |
| Clamping ratio (VC/VBR) | ~1.37 - Tight ratio ensures predictable voltage limiting with minimal overvoltage stress on protected ICs. |
| ESD rating >16 kV HBM | Meets IEC 61000-4-2 Level 4 requirements for system-level ESD immunity without additional front-end protection. |
| Pb-free tape-and-reel packaging | RoHS-compliant P6KE110ARL variant supports automated SMT assembly with 4000 units per reel. |
| UL 497B recognition | Qualified for use in telecom and industrial isolated interfaces where regulatory compliance is mandatory. |
Applications

Use Value: 600 W peak power rating sustains repeated 1 A/100 ms inductive spikes without parameter shift or thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Surface-mount SMB package (vs. axial lead); same VRWM (94 V), slightly higher VC (156 V @ 4.3 A). | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly. | Select SMBJ110A only if board real estate or assembly process favors SMD over through-hole. |
| 1.5KE110A | Same axial package but 1500 W peak power (vs. 600 W); higher IPP (12.3 A), larger case (DO-201AD vs. Surmetic-40). | Overqualified for low-energy transients; may require larger mounting clearance and heatsinking. | Choose 1.5KE110A only when legacy 1.5 kW surge standards (e.g., IEC 61000-4-5 Ed.3) mandate higher energy rating. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110ARL offers optimal balance of surge capability, compact axial form factor, UL 497B certification, and cost-effective tape-and-reel delivery - making it ideal for volume industrial power and control applications where leaded reliability and regulatory alignment are prioritized.

FAQ
What is the maximum clamping voltage of the P6KE110ARL under surge conditions?
The P6KE110ARL has a maximum clamping voltage (VC) of 152 V when subjected to its rated peak pulse current (IPP) of 4 A, measured using the 10/1000 µs standard surge waveform. This value is guaranteed across temperature and lifetime, ensuring downstream components see no more than 152 V during transient events - critical for protecting 100 V-rated MOSFETs and controllers in industrial power rails.
Does the P6KE110ARL meet UL safety standards for isolated circuit protection?
Yes, the P6KE110ARL carries UL 497B recognition (File #E116110) for isolated loop circuit protection, validated across the full P6KE6.8A–P6KE200A series. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing - confirming suitability for telecom interfaces, medical isolation barriers, and other safety-critical applications requiring third-party validation.
What is the working peak reverse voltage (VRWM) specification for the P6KE110ARL?
The P6KE110ARL has a working peak reverse voltage (VRWM) of 94 V, meaning it can continuously block up to 94 V in reverse bias without exceeding 5 µA leakage current. This parameter ensures safe operation on 72–80 V DC systems (e.g., 48 V telecom or 24 V industrial rails with ripple), providing ≥15% margin above nominal voltage to accommodate tolerance and transients.
Is the P6KE110ARL offered in a RoHS-compliant and Pb-free version?
Yes, the P6KE110ARL is the Pb-free tape-and-reel variant (4000 units/reel) of the P6KE110A series, explicitly designated with the "RL" suffix and confirmed compliant per J-STD-609. Its Surmetic−40 axial package uses lead-free terminations and meets RoHS Directive 2011/65/EU, supporting environmentally aligned manufacturing without sacrificing surge performance or reliability.
How does the P6KE110ARL compare to bidirectional TVS diodes like P6KE110CA?
The P6KE110ARL is unidirectional and optimized for DC rail protection where polarity is fixed (e.g., +VCC to GND), offering tighter clamping and lower leakage than bidirectional equivalents. In contrast, P6KE110CA handles AC or reversible signals but exhibits higher capacitance and reduced VRWM margin. Use P6KE110ARL when protecting polarized circuits - its 94 V VRWM and 152 V VC deliver superior precision clamping for industrial DC systems.
