The SMA4F10A is a state-of-the-art Transil™ diode from STMicroelectronics, designed to provide robust protection for sensitive electronic components against voltage transients induced by inductive load switching and lightning. This high-performance device is housed in a compact SMA flat package, engineered to offer a perfect balance between high surge capability and minimal board space consumption, making it an ideal choice for a wide range of space-constrained applications.
Key Features
- Stand-off Voltage: The SMA4F10A has a stand-off voltage of 10V, which is the maximum voltage that can be applied over the diode without causing it to conduct in the forward direction.
- Peak Pulse Power: It can handle peak pulse power dissipation of 400W (10/1000μs), ensuring protection against high energy transients.
- Low Clamping Voltage: This device offers a low clamping voltage, which is the maximum voltage drop across the diode when subjected to a peak impulse current. This ensures sensitive circuit components are shielded from excessive voltages.
- Fast Response Time: The Transil™ diode reacts quickly to transient overvoltage events, providing prompt protection for electronic circuits.
- Low Leakage Current: With its low leakage current, the SMA4F10A ensures minimal power loss when the diode is in the stand-by mode, contributing to energy efficiency in electronic systems.
