Product details
Overview
P6KE16ARLG 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 13.6 V working peak reverse voltage (VRWM), 16 V breakdown voltage (VBR) at 1 mA test current, 22.5 V clamping voltage (VC) at 27 A peak pulse current, and <1 ns response time - ideal for protecting power supply inputs and communication line interfaces against ESD and lightning-induced surges.
For engineers reviewing the P6KE16ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating voltage, VC vs. system withstand rating, surge current capability (IPP = 27 A), Pb-free tape-and-reel packaging (4000 units), and UL 497B recognition for isolated loop circuit protection.
Technical Context
The P6KE16ARLG operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 16 V nominal breakdown threshold. Its clamping action limits transient voltages to ≤22.5 V at 27 A, enabling robust protection of downstream ICs without latch-up or thermal runaway under standardized 1 ms non-repetitive pulses.
It exhibits low leakage (<5 µA at VRWM), a temperature coefficient of 0.086 %/°C for VBR, and thermal resistance of 20 °C/W (junction-to-lead). The device is rated for operation from −55 °C to +175 °C and supports soldering at 230 °C for 10 seconds at 1/16″ from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13.6 V - maximum continuous reverse operating voltage before clamping begins |
| VBR @ IT=1 mA | 15.2–16.8 V - precise avalanche onset range defining turn-on consistency |
| VC @ IPP=27 A | 22.5 V - peak clamped voltage during 1 ms surge, directly limiting stress on protected ICs |
| IPP | 27 A - maximum non-repetitive surge current it can safely divert without degradation |
| PPK | 600 W - peak pulse power handling per 1 ms waveform, per Figure 4 |
| Response Time | <1 ns - enables suppression before most logic or analog ICs experience damage |
| Leakage @ VRWM | <5 µA - negligible standby power loss and signal integrity impact in high-impedance circuits |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 017AA), cathode indicated by band; leads are corrosion-resistant and readily solderable. Maximum lead temperature: 230 °C for 10 s at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Surge return path | Connected to circuit ground or low-side reference; completes clamping loop during transient |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., VCC, data line); conducts avalanche current when voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - meets strike voltage, endurance, and dielectric withstand requirements for telecom and industrial safety compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Surface-mount SMB package; same VRWM (13.6 V), slightly lower VC (23.2 V @ 25.1 A), lower PPK (600 W same) | Designed for board space-constrained designs; lacks axial lead mechanical robustness and UL 497B certification | Select SMBJ16A only when automated SMT placement and footprint reduction outweigh need for UL recognition and through-hole mounting reliability. |
| 1.5KE16A | Same axial package but higher PPK (1500 W); VRWM = 13.6 V, VC = 22.5 V @ 66.7 A, larger case (DO-201AE) | Higher surge capacity suits harsher environments (e.g., utility metering); incompatible pin spacing and thermal mass | Choose 1.5KE16A when system-level surge testing requires >600 W headroom; verify PCB pad layout and heatsinking compatibility. |
Compared with SMBJ16A and 1.5KE16A, P6KE16ARLG offers certified UL 497B compliance and optimized 600 W surge handling in a compact axial form - making it preferred for regulated industrial and medical equipment where safety certification and leaded mechanical stability are mandatory.

FAQ
What is the clamping voltage of P6KE16ARLG and how does it protect downstream components?
The P6KE16ARLG has a maximum clamping voltage (VC) of 22.5 V at 27 A peak pulse current. This means that during a transient event, the device limits the voltage seen by downstream components-such as microcontrollers, transceivers, or power regulators-to no more than 22.5 V. Since many 3.3 V or 5 V logic ICs have absolute maximum ratings around 6–7 V, the P6KE16ARLG must be used with appropriate series impedance (e.g., fuse or resistor) to ensure current limiting. Its fast <1 ns response ensures clamping occurs before sensitive nodes are overstressed.
Is P6KE16ARLG RoHS-compliant and what does the "RLG" suffix indicate?
Yes, P6KE16ARLG is RoHS-compliant. The "RLG" suffix explicitly denotes a Pb-free (lead-free) axial-leaded package supplied in tape-and-reel format (4000 units per reel). This designation aligns with ON Semiconductor's Pb-free strategy and satisfies global environmental regulations including EU RoHS Directive 2011/65/EU. The device uses transfer-molded thermosetting plastic and corrosion-resistant leads compatible with standard reflow and hand-soldering processes.
Does P6KE16ARLG meet UL safety standards, and which standard applies?
Yes, P6KE16ARLG is UL Recognized under UL 497B (File #E210057) for protector applications in isolated loop circuits. This certification covers performance validation across multiple tests: strike voltage breakdown, endurance conditioning, temperature cycling, dielectric withstand, and discharge behavior. UL 497B is specific to telecommunications and industrial signaling circuits - distinguishing it from generic component flammability certifications held by some competitors.
How does the thermal resistance of P6KE16ARLG affect its long-term reliability in high-temperature environments?
P6KE16ARLG has a junction-to-lead thermal resistance (RJL) of 20 °C/W. In practice, this means that under steady-state power dissipation (e.g., from leakage or minor ripple), each watt of power raises the junction temperature 20 °C above the lead temperature. Since the device is rated for operation up to +175 °C junction temperature and lead temperature derating begins above 75 °C, proper PCB copper area and airflow are essential to maintain TL ≤ 75 °C - especially in enclosed industrial enclosures where ambient temperatures exceed 60 °C.
Can P6KE16ARLG be used in bidirectional signal lines such as RS-485 or CAN bus?
No, P6KE16ARLG is a unidirectional TVS diode and must not be used directly across bidirectional signal pairs without additional circuitry. For RS-485 or CAN, bidirectional protection requires either a symmetric pair of unidirectional devices (e.g., two P6KE16ARLGs in series opposition) or a dedicated bidirectional TVS like P6KE16CA. Using P6KE16ARLG alone on a differential line would forward-bias during half-cycles, causing conduction, overheating, and potential failure - violating its specified unidirectional operation.
