Product details
Overview
P4KE200 from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 200 V, clamps transients to ≤287 V at 1.4 A peak pulse current, and operates across –55°C to +175°C junction temperature range - ideal for automotive power supply input stages and industrial PLC I/O protection.
For engineers reviewing the P4KE200 datasheet, P4KE200 pinout, P4KE200 application, or P4KE200 equivalent, key selection criteria include its 162 V working stand-off voltage, <1 μA reverse leakage at rated VWM, DO-41 package compatibility with through-hole PCB layouts, and AEC-Q101 qualification option (P4KE200H) for automotive-grade reliability validation.
Technical Context
The P4KE200 employs an avalanche breakdown mechanism to provide fast, repeatable clamping during ESD and lightning-induced surges. Its 10/1000 μs waveform rating of 400 W defines energy-handling capability under standardized surge conditions per ANSI/IEEE C62.35.
With a typical response time of <1.0 ps from 0 V to VBR, it reacts before most semiconductor damage thresholds are exceeded. The device exhibits a temperature coefficient of 0.108 %/°C for VBR, enabling predictable voltage drift across operating temperature ranges without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 162 V - Maximum continuous DC or RMS voltage the device blocks without conduction; sets safe operating margin below breakdown. |
| VBR @ IT=1 mA | 180–220 V - Measured breakdown voltage range at 1 mA test current; confirms threshold for avalanche initiation. |
| VC @ IPPM=1.4 A | ≤287 V - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream circuitry. |
| PPK | 400 W - Peak pulse power dissipation capability; defines single-event surge energy handling per standard waveform. |
| IR @ VWM | <1 μA - Reverse leakage current at stand-off voltage; ensures minimal standby power loss and signal integrity. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in high-ambient environments like engine compartments. |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package with tin-plated leads compliant to J-STD-002 solderability. |
Pinout & Package
DO-204AL (DO-41) package with axial leads: cathode indicated by band marking; anode and cathode terminals support unidirectional surge shunting from protected line to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to system ground or low-impedance reference; completes clamping current loop during transient events. |
| Cathode | Protected line connection | Connected to input rail or signal line requiring protection; voltage rise above VBR triggers avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche response speed | <1.0 ps - Enables clamping before ESD pulses (IEC 61000-4-2) propagate into sensitive ICs. |
| Clamping ratio (VC/VBR) | ~1.43 - Low ratio ensures minimal overvoltage overshoot relative to breakdown threshold. |
| Leakage control | <1 μA @ 162 V - Preserves battery life in always-on systems and avoids false triggering in high-impedance sensing nodes. |
| Thermal robustness | 175 °C max junction temperature - Supports placement near heat-generating components without derating concerns. |
| Flammability rating | UL 94V-0 molding compound - Meets safety standards for enclosed industrial and automotive enclosures. |
Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |

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 SMAJ200A | Same 200 V nominal, DO-214AC (SMA) surface-mount package; 400 W rating; slightly higher VC (291 V). | Requires SMT reflow process and PCB redesign; unsuitable for through-hole legacy designs. | Select when board space is constrained and automated assembly is available. |
| ON Semiconductor 1.5KE200A | Same 200 V rating, DO-201AD (axial) package; 1500 W peak power; larger footprint and higher clamping (287 V same, but higher energy capacity). | Over-specified for 400 W use cases; introduces unnecessary cost and board area unless higher surge immunity is required. | Select only if system-level testing requires >400 W surge margin or legacy 1.5KE footprint compatibility is mandatory. |
Compared with SMAJ200A and 1.5KE200A, the P4KE200 provides optimal balance of proven 400 W surge handling, DO-41 through-hole compatibility, and tight VC specification - making it ideal for cost-sensitive, high-volume industrial and automotive power entry designs where layout stability and soldering simplicity are prioritized.

FAQ
What is the maximum clamping voltage of the P4KE200 under standard surge conditions?
The P4KE200 clamps to a maximum of 287 V when subjected to a 10/1000 μs waveform with a peak pulse current of 1.4 A. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during a defined surge event. The P4KE200 maintains this clamping performance consistently across its qualified temperature range.
Is the P4KE200 suitable for bidirectional transient suppression?
No, the P4KE200 is a unidirectional TVS diode intended for DC rail protection with polarity-sensitive mounting. For bidirectional applications, the P4KE200CA variant must be used - it features symmetrical breakdown in both directions and lacks a cathode band marking. Using the P4KE200 in reverse-biased configurations will not provide effective clamping.
Does the P4KE200 meet automotive qualification standards?
The base P4KE200 is not AEC-Q101 qualified; however, the P4KE200H variant - identifiable by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested for automotive under-hood applications. Both share identical electrical parameters, but only P4KE200H carries the qualification documentation required for automotive Tier 1 BOM acceptance.
What is the reverse leakage current specification for the P4KE200 at its working voltage?
The P4KE200 exhibits a maximum reverse leakage current of 1 μA when biased at its rated working stand-off voltage of 162 V. This low leakage ensures minimal power loss in always-on systems and avoids interference with high-impedance monitoring circuits - a critical requirement in battery-powered and precision sensing applications using the P4KE200.
Can the P4KE200 be used in parallel to increase surge current handling?
Parallel operation of P4KE200 devices is not recommended due to parameter variation between units - especially VBR tolerance (±10%) - which causes uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power TVS such as the 1.5KE200A or use a TVS array with matched characteristics instead of paralleling discrete P4KE200 units.
