Product details
Overview
P6KE160ARL from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel overvoltage protection of DC power lines and signal paths. It features 136 V working peak reverse voltage (VRWM), 160 V nominal breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPP), and 600 W peak pulse power rating with <1 ns response time.
For engineers reviewing the P6KE160ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin above operating voltage, clamping voltage vs. protected device withstand rating, surge current capability under IEC 61000-4-5 waveforms, and thermal derating behavior at elevated lead temperatures.
Technical Context
The P6KE160ARL operates as a silicon avalanche diode that remains high-impedance below VRWM (136 V), then rapidly transitions to low-impedance conduction when transient voltage exceeds VBR (152–168 V). Its clamping action limits voltage across protected circuitry to ≤219 V during 1 ms 2.7 A pulses, with leakage <5 µA at VRWM and temperature coefficient of 0.108 %/°C.
Designed for non-repetitive transients, it complies with UL 497B for isolated loop circuit protection and supports lead temperature up to +150°C. Thermal resistance junction-to-lead is 20 °C/W, enabling 5.0 W steady-state dissipation at TL ≤ 25°C, derated linearly above 50°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 136 V - Maximum continuous reverse operating voltage before significant leakage; must exceed system DC bus or signal swing. |
| VBR @ IT = 1 mA | 152–168 V - Breakdown range defining reliable avalanche onset; ensures predictable clamping threshold. |
| VC @ IPP = 2.7 A | 219 V - Maximum clamped voltage during 1 ms surge; determines whether protected ICs remain within absolute max ratings. |
| PPK | 600 W - Peak pulse power handling per 1 ms waveform; defines survivability against IEC 61000-4-5 combination wave surges. |
| Response Time | <1 ns - Time from transient onset to clamping conduction; critical for protecting fast logic and analog interfaces. |
| Leakage @ VRWM | <5 µA - Reverse current at rated working voltage; ensures minimal standby power loss and signal integrity impact. |
| Package | Surmetic-40 axial lead (Case 017AA) - Industry-standard through-hole package with cathode band marking and 25.4–31.75 mm lead length. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Surface-mount SMB package; same 136 V VRWM and 219 V VC, but lower 600 W peak power rating derated at higher ambient temperatures. | Requires PCB rework for SMT layout; better suited for space-constrained consumer electronics vs. industrial through-hole assemblies. | Select SMBJ160A only if board real estate is constrained and thermal management supports SMT derating curves. |
| 1.5KE160A | Same axial Surmetic-40 package but higher 1.5 kW peak power rating; larger physical size (Case 017AB); 220 V VC at 6.8 A IPP. | Over-spec'd for 600 W applications; introduces unnecessary cost and board area unless legacy 1.5KE footprint compatibility is required. | Choose 1.5KE160A only when existing designs mandate identical mechanical fit or require >600 W surge headroom. |
Compared with SMBJ160A and 1.5KE160A, the P6KE160ARL offers optimal balance of proven axial-leaded reliability, UL 497B recognition, and precise 600 W surge handling in standard through-hole assembly - making it preferred for industrial power supplies and telecom infrastructure where serviceability and long-term availability matter.

FAQ
What is the maximum clamping voltage of the P6KE160ARL under surge conditions?
The P6KE160ARL has a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current (IPP) of 2.7 A with a 1 ms waveform. This value is measured per Figure 4 in the official ON Semiconductor datasheet and represents the upper limit of voltage the device allows across protected circuitry during transient events - critical for ensuring downstream components remain within their absolute maximum voltage ratings.
Does the P6KE160ARL meet UL safety standards for circuit protection?
Yes, the P6KE160ARL is UL Recognized under UL 497B for isolated loop circuit protection (File #E210057, QVGQ2 category). It has passed rigorous tests including strike voltage breakdown, endurance conditioning, temperature cycling, dielectric withstand, and discharge performance - confirming its suitability for safety-critical protection in telecom, industrial, and medical applications where regulatory compliance is mandatory.
What is the working peak reverse voltage (VRWM) specification for the P6KE160ARL?
The P6KE160ARL has a working peak reverse voltage (VRWM) of 136 V, meaning it can continuously block up to this DC or peak AC voltage without significant leakage current (<5 µA). This parameter is essential for proper selection: VRWM must be ≥ the maximum steady-state voltage of the line being protected to avoid false triggering while maintaining sufficient margin for ripple and tolerance.
How does the P6KE160ARL compare to bidirectional TVS diodes in surge protection design?
The P6KE160ARL is unidirectional and intended for DC or single-polarity signal lines where only positive transients relative to ground require suppression. Unlike bidirectional variants (e.g., P6KE160CA), it cannot clamp negative-going surges - so it must be used with polarity-aware placement. Its advantage lies in tighter VBR control and lower capacitance than equivalent bidirectional parts, improving signal integrity on high-speed DC-coupled lines.
What packaging and reel options are available for the P6KE160ARL?
The P6KE160ARL is supplied in tape-and-reel format with 4,000 units per reel, optimized for automated through-hole insertion. It uses the Surmetic-40 axial-leaded package (Case 017AA) with cathode band marking. Pb-free versions (P6KE160ARLG) are also available, meeting RoHS and JEDEC J-STD-609A Class 3 requirements - both variants maintain identical electrical specifications and mechanical dimensions.
