The P6KE24AE3/54 DO204AC2 is a unidirectional transient voltage suppression (TVS) diode from the P6KE family, housed in the DO204AC2 package. It is designed to protect 24V DC power rails and connected circuitry from transient spikes and surges. This device provides fast, reliable clamping to help prevent damage to sensitive electronics, while delivering a compact, surfacemount protection solution. Key benefits Fast protection: responds quickly to transient spikes to minimize the risk of damage to downstream components. Robust, compact package: DO204AC2 (SMB size) provides a durable, spacesaving protection option suitable for surfacemount assemblies. Easy integration: a singledevice protection solution that mounts directly across a 24V supply line and ground to guard against surges. Pack quantity: comes in a 15piece lot for convenient stocking and boardlevel protection expansion. Brandaligned performance: part of the P6KE TVS diode family, designed to protect systems against transient events on 24V rails. Key attributes Configuration: unidirectional TVS diode Part number: P6KE24AE3/54 Package: DO204AC2 Package type: SMBsize surfacemount diode Voltage rating: 24V (VRWM) for protective applications on 24V lines Material: silicon TVS diode with epoxy encapsulation Pack format: 15 pieces per Functionality and performance Purpose: provides transient suppression for 24V DC circuits, limiting overvoltage events that could damage power rails, controllers, sensors, and drivers. Suitability: well suited for protecting 24V automotive and industrial control systems, PLCs, motor drivers, data lines on 24V networks, and other 24V DC electronics. Protection style: unidirectional clamping suitable for protecting 24V positivegoing transients with reference to ground. Compatibility and applications Auto and vehicle electrical systems operating around 24V that require surge protection on power rails and associated circuits. Industrial automation and control panels using 24V DC logic and actuators, including sensors, controllers, and power modules. 24V DC power supplies and distribution enclosures where rapid transient suppression is needed to maintain system reliability. Use cases Protect a 24V DC control rail in an industrial PLC cabinet from switching and loaddump transients. Guard 24V sensor lines and microcontroller inputs in an automotive or commercial vehicle electrical subsystem against voltage spikes. Provide protection across a 24V power input to a small motor drive or actuator controller to reduce the risk of transient damage. Usage guidance Connect the diode across the protected 24V line and ground. For a unidirectional device, orient the diode with the cathode to the positive supply line and the anode to ground to achieve proper clamping during a positive transient. Ensure proper soldering and reflow compatibility with the DO204AC2 package during PCB assembly. Use as part of a broader protection strategy, including fusing and proper layout practices, to maximize reliability in demanding environments.
