Product details
Overview
P6KE200A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 200V nominal breakdown voltage (190–210V), 171V stand-off voltage, 2.2A peak surge current, 274V maximum clamping voltage at rated surge, and operates across –55°C to +175°C junction temperature.
For engineers reviewing the P6KE200A datasheet, P6KE200A pinout, P6KE200A application, or P6KE200A equivalent, key selection criteria include clamping performance under 10/1000μs transients, low leakage (<1μA @ 171V), AEC-Q101 qualification status, DO-15 mechanical compatibility, and thermal derating behavior above 25°C ambient.
Technical Context
The P6KE200A employs a silicon avalanche junction structure optimized for fast response (<1.0ps rise time from 0V to VBR) and low dynamic impedance to limit transient energy delivered to downstream circuitry. Its unidirectional configuration provides asymmetric conduction-blocking reverse voltage up to 171V while clamping positive surges above 190V.
Rated for 600W non-repetitive peak pulse power per 10/1000μs waveform, the device sustains 5W steady-state dissipation at 75°C with 9.5mm lead length, and supports 100A forward surge current (8.3ms half-sine) - critical for inductive load switching protection in automotive and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 200V - defines mid-point of VBR range; sets primary protection threshold for 24V–48V DC bus applications |
| Breakdown Voltage VBR | 190–210V @ 1mA - ensures reliable avalanche initiation before system damage occurs |
| Stand-Off Voltage VWM | 171V - maximum continuous reverse voltage without significant leakage; allows safe operation below clamping threshold |
| Clamping Voltage VC | 274V @ 2.2A - limits peak voltage seen by protected IC during 10/1000μs surge, enabling robust margin vs. 300V-rated components |
| Peak Pulse Power | 600W - delivers high-energy transient suppression capability for lightning-induced or EFT events |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive, industrial motor drives, and outdoor power electronics |
| Leakage Current | <1μA @ 171V - minimizes standby power loss and avoids false triggering in high-impedance sensing circuits |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is at higher potential |
| Cathode | Avalanche clamping terminal | Marked with band; connected to protected line (e.g., 24V rail); initiates clamping when voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Fast response time | <1.0ps from 0V to VBR - enables clamping before sensitive logic or analog circuitry experiences overvoltage stress |
| Low dynamic impedance | Ensures minimal voltage overshoot during high-di/dt transients, improving protection fidelity for fast-rising ESD/EFT events |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and bond wire integrity - suitable for engine control, body electronics, and ADAS power domains |
| UL recognition | UL file #E-326243 - confirms compliance with safety standards for end-equipment certification in industrial and consumer applications |
| Halogen-free construction | Meets IEC 61249-2-21 - supports RoHS-compliant manufacturing and environmentally responsible product lifecycle management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same 200V nominal, 274V clamping, but SMB package (surface-mount); 600W rating; lower thermal resistance than DO-15 | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly | Select SMBJ200A when board real estate is limited and reflow compatibility is required; P6KE200A remains optimal for through-hole prototyping or high-reliability leaded assemblies. |
| 1.5KE200A | Same DO-15 package and 200V rating, but 1500W peak power; higher clamping voltage (291V); larger junction capacitance | Better for high-energy lightning surges; less suitable for fast EFT where lower VC is critical | Choose 1.5KE200A only if system-level testing confirms need for >600W surge handling; P6KE200A offers tighter clamping and lower leakage for precision-sensitive applications. |
Compared with SMBJ200A and 1.5KE200A, P6KE200A delivers the optimal balance of low clamping voltage (274V), ultra-low leakage (<1μA), and proven AEC-Q101 qualification in a cost-effective through-hole package - making it ideal for automotive and industrial applications where reliability and predictable turn-on behavior are prioritized over raw power rating or footprint size.

FAQ
What is the maximum clamping voltage of the P6KE200A under standard test conditions?
The P6KE200A has a maximum clamping voltage (VC) of 274V when subjected to its rated peak pulse current of 2.2A using the 10/1000μs waveform. This value is measured at TA = 25°C and represents the upper limit of voltage the device allows across its terminals during surge events - a critical parameter for ensuring downstream components remain within their absolute maximum ratings. The P6KE200A maintains this clamping performance consistently across its qualified operating temperature range.
Is the P6KE200A suitable for automotive applications?
Yes, the P6KE200A is AEC-Q101 qualified (as indicated by the "H" suffix variant P6KE200AH), confirming its suitability for automotive applications including engine control units, body electronics, and ADAS power domains. While the base P6KE200A part number itself is not explicitly marked as AEC-Q101 in standard ordering codes, Taiwan Semiconductor's documentation confirms AEC-Q101 qualification applies to all P6KExH variants - and the P6KE200A shares identical electrical, thermal, and mechanical specifications with its qualified counterpart. Designers should specify P6KE200AH for certified automotive use.
How does the P6KE200A differ from the P6KE200 (non-A) version?
The P6KE200A features tighter breakdown voltage tolerance (190–210V) compared to the broader P6KE200 range (180–220V), resulting in more consistent clamping behavior and improved design margin control. It also exhibits lower leakage current and enhanced temperature coefficient uniformity. These refinements make the P6KE200A preferable for applications demanding precise overvoltage thresholds - such as regulated DC-DC input stages or sensor front-ends - where the standard P6KE200 may introduce greater parametric uncertainty during surge events.
What is the recommended PCB layout practice for the P6KE200A in high-surge applications?
For optimal performance, the P6KE200A should be placed as close as possible to the protected node with minimal trace length - especially on the cathode side - to reduce parasitic inductance that could elevate clamping voltage during fast transients. Use wide, short traces connected to solid ground and power planes; avoid vias in the surge current path. Mounting on 5 × 5 mm copper pads per terminal (per datasheet derating guidance) ensures adequate thermal dissipation during repetitive surge events. The P6KE200A's DO-15 package supports both manual and wave soldering with J-STD-002-compliant tin plating.
Does the P6KE200A require external heat sinking in continuous operation?
No, the P6KE200A does not require external heat sinking under normal operating conditions because it is rated for 5W steady-state power dissipation at TA = 75°C with 9.5mm lead length - sufficient for typical transient-suppression duty cycles. However, in applications involving frequent or sustained surge events (e.g., industrial motor drive feedback loops), thermal derating per Figure 2 must be applied. The P6KE200A's 175°C maximum junction temperature and DO-15 package allow direct mounting on thermally robust PCBs without additional heatsinking, provided ambient temperature and airflow meet specification limits.
