The SMA4F24AY is a robust, high-performance transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage spikes and transients. This device is a part of STMicroelectronics' SMA series, offering reliable protection in a compact SMA Flat package, which not only saves space but also ensures a low profile when mounted on a printed circuit board (PCB).

Key Features

• Stand-off Voltage: The SMA4F24AY is designed to provide a stand-off voltage of 24V, making it suitable for a wide range of applications where this voltage level is common.
• Peak Pulse Power: It can handle a peak pulse power of 400W (10/1000μs), ensuring protection against high energy transients.
• Low Clamping Voltage: Upon encountering a voltage spike, the clamping voltage is low, which minimizes the stress on the protected circuit component.
• Fast Response Time: The device reacts almost instantaneously to transient overvoltages, providing prompt protection to the circuitry.
• High Surge Capability: With its high surge capability, the SMA4F24AY is capable of withstanding multiple surge events without degradation.

Applications

The SMA4F24AY is ideal for protecting sensitive electronics in various applications, including:

• Portable Devices
• Power Supply Lines
• Industrial Systems
• Networking Equipment
