Product details
Overview
P6KE110ARLG from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic−40 package, designed for parallel clamping of high-energy transients. It delivers 600 W peak pulse power at 1 ms, clamps to 152 V at 4 A peak pulse current, and features <1 ns response time with 94 V working peak reverse voltage - used in industrial power supplies and communication line protection.
For engineers reviewing the P6KE110ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ 94 V, VC ≤ 152 V @ IPP = 4 A, UL 497B recognition for isolated loop circuits, Pb−free tape-and-reel packaging (4000 units), and thermal resistance of 20 °C/W.
Technical Context
The P6KE110ARLG operates as a silicon avalanche diode, triggered by reverse-biased breakdown above its specified VBR range (105–116 V @ IT = 1 mA). Its clamping action limits transient overvoltage across protected circuit nodes with minimal leakage (<5 µA @ 94 V) and stable temperature coefficient (0.107 %/°C).
It complies with UL 497B for isolated loop circuit protection and supports nonrepetitive surge pulses per Figure 4 (10/1000 µs waveform), with derating applied above TL = 25 °C and full power limited to lead temperature ≤ 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 94 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 105 V / 116 V @ IT = 1 mA - ensures reliable avalanche initiation within defined tolerance band |
| VC @ IPP | 152 V @ 4 A - clamped voltage during 1 ms surge, defining worst-case stress on downstream components |
| PPK | 600 W @ 1 ms - peak transient energy absorption capacity without failure |
| IR @ VRWM | <5 µA - negligible standby leakage, critical for low-power or high-impedance sensing circuits |
| RJL | 20 °C/W - junction-to-lead thermal resistance enables effective heat dissipation through leads |
| Response Time | <1 ns - enables suppression of fast-rising ESD and lightning-induced transients before damage occurs |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), void-free thermosetting body with corrosion-resistant, solderable leads. Cathode indicated by polarity band. Maximum soldering temperature: 230 °C at 1/16″ from case for 10 seconds. Mounting position: any.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side reference | Connected to ground or low-potential node in unidirectional clamp configuration |
| Cathode | Reverse-biased clamping terminal / high-side input | Connected to protected line; avalanche breakdown initiates here during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - meets safety requirements for telecom and industrial interfaces |
| ESD Robustness | Class 3 (>16 kV HBM) - withstands human-body-model electrostatic discharge without degradation |
| Pb−Free Tape & Reel | P6KE110ARLG variant supplied in RoHS-compliant, 4000-unit reel - supports automated SMT assembly with lead-free process compatibility |
| Low Clamping Ratio | VC/VBR ≈ 1.45 (152 V / 105 V) - tight voltage margin between breakdown and clamping improves system-level surge margin |
| Stable Tempco | 0.107 %/°C - predictable VBR drift over −55 to +175 °C operating range, enabling reliable performance in harsh environments |
Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: Protects AC/DC converter inputs and DC bus lines against lightning surges and load dump transients in factory automation systems. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed in parallel with rectifier output or bulk capacitor to clamp overvoltage spikes. Use Value: Limits transient voltage to ≤152 V, preventing MOSFET gate oxide rupture and electrolytic capacitor overvoltage failure. |

IC Role / Device Role / Timing Role: Standoff device connected between signal line and ground, activated only during >94 V transients. Use Value: Maintains signal integrity under 1 kV/µs fast transients while adding <1 pF capacitance - no data rate degradation. |
| Medical Equipment Input Stage | Process Control Sensor Interface |
Use Scenario: Safeguards front-end power entry of diagnostic imaging devices and infusion pumps against mains-borne surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary overvoltage clamp on L/N inputs prior to EMI filter and bridge rectifier.

Use Scenario: Protects 4–20 mA current loop inputs in PLC analog modules from field wiring faults and electrostatic coupling. IC Role / Device Role / Timing Role: Reverse-biased protector across loop terminals, conducting only during fault conditions. Use Value: 5 µA max leakage avoids measurement error in high-impedance current sense paths; 20 °C/W RJL enables thermal stability during repeated surges. |
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 P6KE); same VRWM (94 V), lower PPK (600 W vs. 600 W), higher VC (183 V @ 3.3 A) | Requires PCB layout change; better suited for space-constrained designs with automated assembly | Select when board real estate is limited and reflow compatibility is required over through-hole mounting. |
| 1.5KE110A | Higher PPK (1500 W), same VRWM (94 V), larger DO-201AD package, higher VC (187 V @ 8 A), not UL 497B recognized | Used where higher single-pulse energy handling is needed but safety certification is not mandated | Choose for non-certified industrial motor drives where surge amplitude exceeds 600 W capability. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110ARLG offers certified UL 497B compliance, axial-leaded ease of prototyping and repair, and tighter clamping (152 V vs. ≥183 V), making it optimal for certified, serviceable, and cost-sensitive industrial power interfaces.

FAQ
What is the working peak reverse voltage (VRWM) of the P6KE110ARLG?
The P6KE110ARLG has a working peak reverse voltage (VRWM) of 94 V, meaning it remains non-conductive up to this DC or continuous peak voltage level. This value ensures compatibility with 72–90 V nominal DC bus systems and 100 VAC-derived supplies, and is confirmed in Table 3 of the official ON Semiconductor datasheet revision 7.
Does the P6KE110ARLG meet UL 497B certification?
Yes, the P6KE110ARLG is UL 497B recognized for isolated loop circuit protection (File #E116110, QVGV2 category). This certification covers surge endurance, dielectric withstand, and discharge testing - explicitly confirmed on page 6 of the P6KE6.8A Series datasheet - and applies to all P6KE6.8A–P6KE200A unidirectional variants.
What is the clamping voltage (VC) and peak pulse current (IPP) for the P6KE110ARLG?
The P6KE110ARLG clamps to a maximum of 152 V when subjected to a 4 A peak pulse current (IPP), measured using the standard 1 ms exponential waveform per Figure 4. This VC/IPP pair defines the upper voltage limit imposed on protected circuitry during transient events and is listed in the electrical characteristics table on page 3 of the datasheet.
Is the P6KE110ARLG RoHS-compliant and what does the 'G' and 'RL' suffix indicate?
Yes, the P6KE110ARLG is RoHS-compliant and Pb−free. The 'G' suffix denotes Pb−free packaging, and 'RL' indicates tape-and-reel packaging (4000 units per reel). This configuration is explicitly called out in the Ordering Information section on page 1 of the datasheet and qualifies for lead-free reflow processes.
What is the thermal resistance and maximum operating temperature of the P6KE110ARLG?
The P6KE110ARLG has a junction-to-lead thermal resistance (RJL) of 20 °C/W and an operating temperature range of −55 °C to +175 °C. These values are specified in the Maximum Ratings table (page 1) and ensure reliable operation in high-ambient environments such as enclosed power enclosures or under-hood automotive modules.
