The SMA6F170AY is a high-performance transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This device is part of STMicroelectronics' Transil range, which offers reliable protection by clamping action within picoseconds from the occurrence of a transient event.

Key Features

• High Surge Capability: With its ability to handle surge currents up to 600W (10/1000µs), the SMA6F170AY provides robust protection against high-energy transients.
• Low Clamping Voltage: The device features a low clamping voltage, ensuring that sensitive components are shielded from transient overvoltages without significant additional power dissipation.
• Unidirectional Protection: As a unidirectional TVS diode, the SMA6F170AY is designed to protect against positive-going transients, making it suitable for DC power supply applications.
• Wide Operating Junction Temperature Range: It operates effectively over a broad temperature range from -55°C to 150°C, ensuring reliability in harsh environments.
• Low Leakage Current: The device has a very low leakage current, minimizing power loss and making it ideal for energy-sensitive applications.
• Compact Package: Housed in an SMA flat package, the SMA6F170AY saves space on the PCB while still providing high surge capability.
