Description and Introduction

600 WATT PEAK POWER TRANSIENT VOLTAGE SUPPRESSORS The **P6KE400A** from ST is a high-performance transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient events. This component is part of the **P6KE series**, renowned for its fast response time and robust clamping capability, making it ideal for applications requiring reliable overvoltage protection.  

With a **standoff voltage of 342V** and a **breakdown voltage range of 380V to 420V**, the P6KE400A efficiently clamps transient voltages, diverting excess energy away from critical components. Its **peak pulse power rating of 600W** (10/1000μs waveform) ensures robust protection against surges, including those caused by lightning strikes, inductive load switching, or electrostatic discharge (ESD).  

The P6KE400A features a **low clamping voltage** and **fast response time** (typically less than 1ps), making it suitable for safeguarding power supplies, communication lines, and industrial control systems. Available in a **DO-15 package**, it offers ease of integration into various circuit designs.  

Engineers favor the P6KE400A for its reliability and compliance with industry standards, ensuring consistent performance in demanding environments. Whether used in automotive, telecommunications, or consumer electronics, this TVS diode provides essential protection against transient voltage threats.

Application Scenarios & Design Considerations

600 WATT PEAK POWER TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • 1.5KE400A --: Same 400V standoff unidirectional TVS in a larger 1500W peak power package; higher surge rating makes it a robust drop-in upgrade with similar clamping characteristics.
  • SMAJ400A --: 400V unidirectional TVS diode in SMA package offering a compact surface-mount alternative with comparable standoff and clamping voltage for lower-power surge protection.
  • SMBJ400A --: 400V unidirectional TVS in SMB package providing a surface-mount option with 600W peak pulse power, suitable where through-hole P6KE parts are being replaced.
  • 1.5KE400A --: Same 400V standoff unidirectional TVS in a larger 1.5kW package, widely available and a common drop-in upgrade for higher surge margin.
  • SMAJ400A --: 400V unidirectional TVS diode with similar clamping behavior in a compact SMA package, suitable when board space is limited.
  • P4KE400A --: 400V unidirectional transient voltage suppressor from a different series with comparable 400W rating and similar electrical characteristics.
