Product details
Overview
P6KE200AG from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel overvoltage protection of sensitive electronics. It features 600 W peak pulse power (1 ms), 200 V breakdown voltage (VBR = 190–210 V @ IT = 1 A), clamping voltage of 274 V at 2.2 A peak pulse current (IPP), and <1 ns response time - used in industrial power supplies, medical equipment, and communication line surge protection.
For engineers reviewing the P6KE200AG datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (VRWM = 171 V), low leakage (<5 µA @ VRWM), UL 497B recognition for isolated loop circuits, thermal resistance (RJL = 20 °C/W), and Pb-free axial lead compliance per RoHS.
Technical Context
The P6KE200AG operates as a silicon avalanche diode, triggered when reverse voltage exceeds its specified VBR range (190–210 V), entering low-impedance clamping mode to divert surge energy away from protected circuitry. Its unidirectional polarity requires cathode-band orientation toward positive rail in DC applications.
It complies with UL 497B for isolated loop circuit protection and supports non-repetitive 600 W transients per Figure 4 waveform (tp = 1 ms, 50% decay). Thermal derating follows Figure 5: steady-state power drops from 5.0 W at TL ≤ 25°C to zero at TL = 175°C with 3/8″ lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 171 V - maximum continuous reverse operating voltage before clamping begins |
| VBR @ IT=1 A | 190–210 V - guaranteed avalanche breakdown range defining turn-on threshold |
| VC @ IPP=2.2 A | 274 V - maximum clamped voltage during 1 ms surge, limiting stress on downstream ICs |
| IPP | 2.2 A - peak pulse current corresponding to 600 W rating at VC |
| Leakage @ VRWM | <5 µA - minimal standby power loss and signal integrity impact in high-impedance circuits |
| Response Time | <1 ns - ensures clamping activation before most ESD or lightning-induced transients propagate |
| Thermal Resistance RJL | 20 °C/W - defines junction-to-lead temperature rise under steady-state dissipation |
Pinout & Package
Surmetic-40 axial-leaded plastic package (Case 017AA), 8.38–8.89 mm body length, 3.30–3.68 mm diameter, with cathode indicated by a colored band. Leads are solderable, corrosion-resistant, rated for 260°C for 10 s at 1/16″ from case.

| Cathode | High-side connection point | Marked with band; connected to protected line or positive rail to enable reverse-biased clamping |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Power Supply Protection | Medical Equipment Surge Suppression |
|---|---|
Use Scenario: Protecting DC output rails of AC/DC converters against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed across output capacitor to clamp overvoltage spikes before they reach downstream regulators or microcontrollers. Use Value: Limits transient voltage to ≤274 V, preventing damage to 200 V-rated electrolytic capacitors and 3.3 V/5 V logic interfaces. | Use Scenario: Safeguarding patient-connected analog front-ends (e.g., ECG leads) from defibrillator-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on isolated signal paths compliant with UL 497B requirements for medical isolation barriers. Use Value: UL-recognized clamping enables certified design reuse without additional system-level surge testing. |
| Telecom Line Interface Protection | Process Control I/O Module Protection |
Use Scenario: Shielding RS-485 or Ethernet PHY lines from lightning-induced common-mode surges in outdoor base stations. IC Role / Device Role / Timing Role: Paired with gas discharge tube (GDT) in hybrid protection network; P6KE200AG handles fast-rising edge while GDT absorbs bulk energy. Use Value: Sub-1 ns response captures initial transient overshoot before GDT fires, reducing overall let-through voltage. | Use Scenario: Protecting 4–20 mA current loop inputs in PLC analog input modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Reverse-biased across loop terminals to clamp induced surges exceeding 171 V working voltage. Use Value: Maintains loop integrity by limiting voltage excursion below 274 V, avoiding op-amp saturation or ADC latch-up. |
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 (vs. axial); same VRWM = 171 V, VC = 274 V, but lower IPP = 2.18 A (590 W) | Requires PCB re-layout; better suited for automated SMT assembly and space-constrained designs | Select SMBJ200A when board real estate is limited and reflow compatibility is required. |
| 1.5KE200A | Higher peak power (1500 W), larger DO-201AD package; identical VRWM/VC specs but higher thermal mass and lead inductance | Better for high-repetition surges; less suitable for ultra-fast edge protection due to ~1.5 ns typical response | Choose 1.5KE200A where sustained surge duty cycles or higher energy absorption is prioritized over minimal overshoot. |
Compared with SMBJ200A and 1.5KE200A, the P6KE200AG offers optimal balance of axial-lead serviceability, 600 W surge capability, sub-1 ns response, and UL 497B certification - making it preferred for field-serviceable industrial power and medical isolation applications where leaded reliability and regulatory alignment are critical.

FAQ
What is the maximum working peak reverse voltage (VRWM) for P6KE200AG?
The P6KE200AG has a maximum working peak reverse voltage (VRWM) of 171 V. This value defines the highest continuous DC or peak AC voltage the device can withstand in reverse bias without entering conduction. Engineers must ensure system operating voltage remains at or below this level to prevent premature clamping or leakage-related power loss. The P6KE200AG is therefore appropriate for 120/240 VAC-derived DC rails or 150 VDC bus applications.
How does the clamping voltage (VC) of P6KE200AG compare to its breakdown voltage (VBR)?
The P6KE200AG exhibits a VBR range of 190–210 V at 1 A test current, while its maximum clamping voltage VC is 274 V at 2.2 A peak pulse current. This 64–84 V differential reflects the dynamic impedance of the avalanche junction under surge conditions. The relatively tight VC/VBR ratio confirms low clamping overshoot - critical for protecting 200 V-rated components downstream of the P6KE200AG.
Is P6KE200AG certified for use in safety-critical isolation circuits?
Yes, the P6KE200AG carries Underwriters Laboratories (UL) Recognition under standard UL 497B for isolated loop circuit protection (File #E210057, QVGQ2 category). This certification validates its performance in telecom and medical isolation barriers - including strike voltage breakdown, endurance conditioning, and dielectric withstand tests. The P6KE200AG is explicitly included in the UL-recognized scope covering P6KE6.8A–P6KE200A.
What is the thermal resistance and steady-state power rating of P6KE200AG?
The P6KE200AG 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, derating linearly to zero at TL = 175°C with 3/8″ lead length. This means sustained dissipation above ~1.5 W requires heatsinking or airflow - the P6KE200AG is optimized for transient, not continuous, power handling.
Does P6KE200AG meet RoHS and lead-free requirements?
Yes, the "G" suffix in P6KE200AG denotes a Pb-free (RoHS-compliant) Surmetic-40 package. ON Semiconductor confirms full compliance with Directive 2011/65/EU, with lead content below 1000 ppm. The device uses matte tin-plated leads and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard soldering profiles, including peak temperature of 260°C for 10 seconds.
