Description and Introduction

TRANSIL The **P6KE300ARL** from ST is a high-performance transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transients. This bidirectional device is part of the **P6KE series**, offering robust clamping capabilities with a **standoff voltage of 300V** and a **peak pulse power dissipation of 600W**.  

Engineered for reliability, the P6KE300ARL responds rapidly to overvoltage events, clamping excessive voltages to safe levels within nanoseconds. Its low clamping voltage ensures minimal stress on downstream components, making it ideal for applications in **power supplies, industrial systems, telecommunications, and automotive electronics**.  

Housed in a **DO-15 package**, this TVS diode is compact yet durable, suitable for space-constrained designs. It meets stringent industry standards, including **AEC-Q101** for automotive-grade reliability, ensuring stable performance under harsh conditions.  

Key features include:  
- **Bidirectional protection** against positive and negative transients  
- **Low leakage current** for energy-efficient operation  
- **High surge capability** for robust circuit protection  

The P6KE300ARL is a dependable solution for safeguarding critical electronics from electrostatic discharge (ESD), lightning-induced surges, and other transient threats, enhancing system longevity and reliability.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • 1.5KE300A --: Same 300V standoff unidirectional TVS in a larger 1.5kW package; higher surge rating makes it a safe drop-in upgrade with similar clamping behavior.
  • SMAJ300A --: 300V standoff unidirectional TVS diode with comparable clamping voltage; smaller SMA package suits space-constrained designs with lower surge requirements.
  • P6SMB300A --: 600W unidirectional TVS with 300V standoff in SMB package; equivalent surge class and electrical characteristics to the original.
  • 1N6296A --: Unidirectional 1500W TVS diode with 300V standoff voltage, functionally equivalent to the P6KE300A and widely available.
  • SMCJ300A --: 1500W SMC-package unidirectional TVS with 300V standoff, same clamping class and suitable as a drop-in replacement.
  • 5KP300A --: 5000W axial TVS diode with 300V standoff, offers higher surge rating and can replace the P6KE300A in most protection circuits.
