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 P4KE440A TVS Diode  
The **P4KE440A** is a high-performance **Transient Voltage Suppression (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and transient events. Manufactured by **GS**, this component is part of the **P4KE series**, which is widely recognized for its reliability in surge protection applications.   With a **standoff voltage of 440V** and a **peak pulse power dissipation of 400W**, the P4KE440A effectively clamps transient voltages to safe levels, safeguarding downstream components from damage. Its fast response time—typically in the **nanosecond range**—ensures rapid reaction to overvoltage conditions, making it suitable for use in power supplies, communication systems, and industrial electronics.   The diode features a **unidirectional configuration**, meaning it is optimized for protecting circuits against positive voltage transients. It is housed in a **DO-41 package**, providing robust mechanical strength and ease of integration into various circuit designs.   Key applications include **surge protection in AC/DC power lines, automotive systems, and telecommunications equipment**. Engineers favor the P4KE440A for its **high surge capability, low clamping voltage, and durability**, making it a trusted solution for transient suppression in demanding environments.   For detailed specifications, always refer to the official datasheet to ensure proper implementation in your design. |
