Product details
Overview
P6KE200ARL 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 features 200 V working peak reverse voltage (VRWM), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPP), and 600 W peak pulse power rating at 1 ms. Used to protect power supplies, industrial controls, and communication interfaces against ESD and lightning-induced surges.
For engineers reviewing the P6KE200ARL datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to system operating voltage, surge current capability under 1 ms pulses, thermal derating above 50°C, and UL 497B recognition for isolated loop circuit protection.
Technical Context
The P6KE200ARL operates as a silicon avalanche diode with fast turn-on response (<1 ns), enabling effective suppression of sub-microsecond transients. Its breakdown voltage (VBR) is specified at 190–210 V (min–max) with 1 mA test current, and it exhibits a temperature coefficient of 0.108 %/°C for VBR stability across −55°C to +150°C.
Thermal design relies on junction-to-lead resistance (RJL = 20 °C/W) and steady-state power dissipation (5.0 W at TL ≤ 25°C, derated linearly above 50°C). Mounting position is unrestricted, and polarity is marked by cathode band; anode and cathode terminals are axially oriented with 3/8″ lead length standard for thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 171 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC/peak AC voltage. |
| VC @ IPP | 274 V @ 2.2 A - Clamped voltage during 1 ms surge; defines worst-case overvoltage seen by protected circuitry. |
| PPK | 600 W @ 1 ms - Peak non-repetitive surge power handling; determines survivability of lightning or EFT events. |
| IR @ VRWM | 5 µA max - Reverse leakage at rated VRWM; ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| TJ Range | −55°C to +150°C - Full operational junction temperature range; supports deployment in automotive under-hood or industrial environments. |
| UL Recognition | UL 497B QVGQ2 - Certified for isolated loop circuit protection; validates compliance with safety standards for telecom and industrial isolation barriers. |
Pinout & Package

| Cathode | Current exit terminal during reverse-biased clamping | Connected to protected line (e.g., VBUS, signal line); clamps to anode when transient exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| Clamp Response Time | <1 ns typical - Enables suppression of nanosecond-scale ESD events before downstream ICs experience overstress. |
| ESD Robustness | Class 3 HBM (>16 kV) - Meets IEC 61000-4-2 Level 4 requirements for system-level ESD immunity. |
| Surge Current Handling | 2.2 A IPP at 274 V - Sustains defined 1 ms transient without parametric shift or failure per Figure 4 waveform. |
| Thermal Derating | 50 mW/°C above TL = 50°C - Enables predictable power handling in enclosed enclosures or high-ambient environments. |
Applications
| Industrial Power Supply Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: Input stage of 24 V/48 V DC industrial power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rails to clamp surges before they reach primary-side controller and bulk capacitor. Use Value: Limits transient overvoltage to ≤274 V, preventing MOSFET avalanche failure and electrolytic capacitor overvoltage stress. | Use Scenario: RS-485 data lines in building automation systems subject to induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Parallel-connected TVS on differential pair (A/B) referenced to local ground, absorbing common-mode energy. Use Value: Maintains signal integrity by clamping transients within 1 ns while meeting UL 497B requirements for isolated loop safety. |
| Medical Equipment Surge Suppression | Process Control Sensor Interface Protection |
Use Scenario: Front-end analog inputs of patient monitoring devices connected to external sensors via unshielded cables. IC Role / Device Role / Timing Role: Low-leakage (5 µA) TVS on each analog channel to suppress ESD without affecting DC accuracy or offset drift. Use Value: Prevents latch-up or damage to precision op-amps and ADCs while preserving <1 LSB error contribution from leakage. | Use Scenario: 4–20 mA current loop inputs in PLC modules installed in electrically noisy factory environments. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; unidirectional P6KE200ARL used on supply rail side to absorb positive-going transients only. Use Value: Ensures loop integrity by limiting rail overvoltage to 274 V, avoiding regulator shutdown or current source saturation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Surface-mount SMB package; same VRWM (171 V), slightly higher VC (275 V), lower IPP (2.2 A vs. 2.2 A - identical), 600 W rating. | Requires PCB redesign for SMD layout; better high-frequency performance due to lower parasitic inductance. | Select SMBJ200A when board space is constrained and automated assembly is preferred; verify thermal pad layout for 5 W steady-state dissipation. |
| P6KE200A | Same die and electrical specs; axial-leaded version without tape-and-reel packaging (bulk box, 1000 units). | No difference in circuit function or placement; differs only in packaging format and ordering unit. | Select P6KE200A for manual prototyping or low-volume builds where reel feeding is unnecessary. |
Compared with SMBJ200A, P6KE200ARL offers proven axial-leaded reliability and easier hand-soldering, while P6KE200A provides identical protection in non-reel form-both retain full UL 497B recognition and 200 V clamping profile.

FAQ
What is the clamping voltage of P6KE200ARL at its rated peak pulse current?
The P6KE200ARL has a maximum clamping voltage (VC) of 274 V at its rated peak pulse current (IPP) of 2.2 A, measured using the 1 ms exponential waveform defined in Figure 4 of the datasheet. This value represents the upper limit of voltage imposed on protected circuitry during a standardized surge event, and must be compared directly against the absolute maximum ratings of downstream components to ensure safe operation.
Is P6KE200ARL certified for safety-critical isolation applications?
Yes, P6KE200ARL carries UL 497B recognition (File #E210057, Category QVGQ2) for isolated loop circuit protection - a certification covering strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing. This makes P6KE200ARL suitable for use in telecom interfaces, medical isolation barriers, and industrial signal conditioning where regulatory compliance is mandatory.
What is the maximum reverse leakage current for P6KE200ARL at its working voltage?
The P6KE200ARL specifies a maximum reverse leakage current (IR) of 5 µA at its working peak reverse voltage (VRWM) of 171 V. This low leakage ensures minimal power loss and avoids loading effects in high-impedance circuits such as sensor bias networks or precision reference paths where even nanoamp-level currents could induce measurable errors.
Can P6KE200ARL be used in bidirectional transient protection configurations?
No, P6KE200ARL is a unidirectional TVS diode and must be used with correct polarity: cathode to the protected line, anode to ground or lower potential. For bidirectional protection, a separate device such as P6KE200CA (center-tapped, bidirectional variant) is required. Using P6KE200ARL in reverse orientation will not provide clamping on negative transients and may result in catastrophic failure.
What is the thermal resistance and steady-state power rating of P6KE200ARL?
P6KE200ARL 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) ≤ 25°C, derated linearly at 50 mW/°C above TL = 50°C. These values assume 3/8″ lead length and define the continuous power handling capability when mounted with adequate heat sinking - critical for applications with repetitive surges or elevated ambient temperatures.
