Product details
Overview
P6KE200A A0G from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a nominal breakdown voltage of 200 V, clamping voltage of 274 V at 2.2 A peak surge current, stand-off voltage of 171 V, and low dynamic impedance for effective energy diversion during ESD or lightning-induced transients - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE200A A0G datasheet, P6KE200A A0G pinout, P6KE200A A0G application, or P6KE200A A0G equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25°C, unidirectional polarity marking, and DO-204AC (DO-15) package compatibility with manual or wave-soldered PCB assembly.
Technical Context
The P6KE200A A0G operates as a silicon avalanche diode with sharp reverse-breakdown characteristics, triggered when reverse voltage exceeds its 190–210 V breakdown range at 1 mA test current. Its fast response time (<1.0 ps from 0 V to VBR) enables suppression of sub-nanosecond ESD events before downstream IC damage occurs.
Thermal design relies on its 175°C maximum junction temperature and 5 W steady-state power dissipation at 75°C ambient (with 9.5 mm lead length), requiring appropriate copper pad area per JEDEC standards. The device is rated for non-repetitive 600 W peak pulse power at 10/1000 µs waveform, with linear derating above 25°C per Fig.2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges without failure, suitable for IEC 61000-4-5 Level 3/4 compliance testing |
| Breakdown Voltage VBR | 190–210 V @ 1 mA - defines precise triggering threshold for overvoltage clamping in 200 V systems |
| Stand-Off Voltage VWM | 171 V - ensures no conduction during normal 200 V rail operation, minimizing leakage and power loss |
| Clamping Voltage VC | 274 V @ 2.2 A - limits transient voltage seen by protected circuitry to safe margin below IC absolute maximum ratings |
| Junction Temperature Range | −55°C to +175°C - supports deployment in under-hood automotive and industrial environments with wide thermal cycling |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with tin-plated leads compliant to J-STD-002 solderability |
| Leakage Current | <1 µA @ 171 V - negligible standby current draw, critical for battery-backed or low-power monitoring circuits |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, cathode band marked on one end. Leads are pure tin-plated, RoHS-compliant, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / low-side reference | Connected to ground or lower-potential node; forms clamping path when cathode is at higher transient voltage |
| Cathode | Transient voltage input / protected line connection | Connected to line being protected (e.g., 200 V DC bus); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600 W surge rating (10/1000 µs) | Enables single-event protection against severe lightning-induced surges in AC/DC front-end stages |
| Clamping ratio (VC/VBR) ≈ 1.38 | Indicates tight voltage control - lower ratio than many competing TVS devices, reducing stress on downstream components |
| Response time <1.0 ps | Guarantees suppression initiation before nanosecond-scale ESD pulses propagate into sensitive analog or digital inputs |
| AEC-Q101 qualification option (H suffix) | P6KE200A A0G itself is not AEC-Q101 qualified; however, P6KE200AH A0G variant meets automotive reliability requirements |
| UL 94V-0 molding compound | Provides flame-retardant encapsulation essential for safety-critical industrial and transportation equipment |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

| Telecom DC Feeder Protection | Renewable Energy Inverter DC Link |
Use Scenario: −48 V telecom DC distribution system where remote radio units experience induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Bidirectional protection not applicable - P6KE200A A0G is unidirectional; used only on positive rail side with complementary grounding scheme. Use Value: Clamps 10/1000 µs surges up to 600 W without degradation, meeting GR-1089-CORE Level 3 surge immunity requirements. |
Use Scenario: 200 V DC link between PV array and MPPT converter in residential solar inverters, subject to grid-switching transients and partial shading-induced voltage spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC+ rail, coordinated with MOVs and fuses for staged protection architecture. Use Value: 274 V clamping voltage provides 26 V design margin below typical 300 V IGBT blocking rating, extending device lifetime under repeated surge stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse P6KE200A | Identical electrical specs (VBR, VC, PPK), same DO-15 package, but UL file #E150247 and different date-code marking format | No functional difference; validated in identical 200 V rail protection layouts | Select when dual-sourcing required or Littelfuse supply chain alignment preferred |
| Vishay 1.5KE200A | Same 200 V nominal, but 1.5 kW peak power rating (10/1000 µs), larger DO-201AD package, higher clamping voltage (287 V) | Higher surge capacity suits infrequent extreme events; requires PCB footprint change and thermal re-evaluation | Choose for enhanced surge margin where space and thermal budget allow larger package |
Compared with P6KE200A A0G, Littelfuse's P6KE200A offers direct form-fit-function replacement with identical layout impact, whereas Vishay's 1.5KE200A trades smaller footprint for higher surge headroom and looser clamping - necessitating board redesign and thermal validation.

FAQ
What is the maximum clamping voltage of the P6KE200A A0G at its rated peak surge current?
The P6KE200A A0G has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak surge current of 2.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during transient events - a critical parameter for verifying safe operating margins of downstream 300 V-rated components in the same circuit as the P6KE200A A0G.
Is the P6KE200A A0G suitable for bidirectional transient protection?
No, the P6KE200A A0G is a unidirectional TVS diode, intended only for protection against positive-going transients on a referenced rail. For bidirectional protection, the P6KE200CA A0G variant must be used - it features symmetrical breakdown in both directions and lacks a cathode band marking. Using P6KE200A A0G in a bidirectional configuration risks failure during negative transients, as confirmed in the "Devices for Bipolar Applications" section of the TSC datasheet for the P6KE SERIES.
Does the P6KE200A A0G meet AEC-Q101 automotive qualification?
The P6KE200A A0G is not AEC-Q101 qualified. Only variants with the "H" suffix (e.g., P6KE200AH A0G) are AEC-Q101 certified per the Ordering Information table in the TSC datasheet. The "A0G" suffix denotes green compound and ammo box packaging but does not imply automotive qualification. Engineers designing for automotive applications must specify the H-suffix version to ensure compliance with stress-test requirements for temperature cycling, humidity, and mechanical shock.
What is the thermal derating behavior of the P6KE200A A0G above 25°C ambient?
The P6KE200A A0G follows a linear derating curve for peak pulse power above 25°C ambient, as shown in Fig.2 of the TSC datasheet: at 75°C, its 600 W rating reduces to approximately 480 W, and at 125°C, it drops to ~360 W. Steady-state power dissipation is rated at 5 W only when mounted on 5 × 5 mm copper pads per terminal and operated at 75°C ambient - exceeding this requires thermal modeling or forced-air cooling to maintain junction temperature ≤175°C.
How does the leakage current of the P6KE200A A0G compare to its stand-off voltage?
The P6KE200A A0G exhibits a maximum reverse leakage current (ID) of 1 µA when biased at its rated stand-off voltage of 171 V, as specified in the Electrical Specifications table. This ultra-low leakage ensures minimal power loss in always-on 200 V systems and avoids false triggering in high-impedance sensing circuits - a key advantage over older-generation TVS diodes that may exceed 5 µA at similar VWM levels, making the P6KE200A A0G especially suitable for energy-efficient designs.
