Description and Introduction

GLASS PASSIVATED JUNCTION TRANSIENT VOLTAGE SUPPRESSOR(VOLTAGE - 6.8 TO 440 Volts 400 Watt Peak Power 1.0 Watt Steady State) # Introduction to the P4KE27A TVS Diode  

The **P4KE27A** is a high-performance transient voltage suppressor (TVS) diode manufactured by **TCL**. Designed to protect sensitive electronic circuits from voltage spikes and transients, this component is widely used in applications requiring robust surge protection.  

With a **standoff voltage of 27V** and a **peak pulse power rating of 400W**, the P4KE27A effectively clamps transient overvoltages, diverting excess energy away from critical components. Its fast response time—typically in **picoseconds**—ensures minimal risk of damage from electrostatic discharge (ESD), lightning-induced surges, or inductive load switching.  

The diode operates in a **unidirectional** configuration, making it suitable for DC circuits where polarity must be maintained. Its compact **DO-41** package allows for easy integration into various circuit designs while maintaining high reliability under harsh conditions.  

Common applications include **power supplies, communication systems, automotive electronics, and industrial controls**, where transient suppression is essential for longevity and performance. The P4KE27A meets industry standards for surge protection, ensuring dependable operation in demanding environments.  

For engineers and designers seeking a cost-effective yet robust solution for transient voltage suppression, the P4KE27A offers a balance of performance, durability, and efficiency.

Alternative Part Number

  • 1N6279A --: Unidirectional 1500W transient voltage suppressor with 27V standoff, same axial package and clamping behavior as the P4KE27A.
  • SMAJ27A --: 400W unidirectional TVS diode with 27V standoff in SMA package, suitable drop-in replacement where lower peak power is acceptable.
  • P6KE27A --: 600W unidirectional TVS diode with 27V standoff in DO-15 axial package, same voltage class and similar surge rating.
