The STMicroelectronics SMA4F170A is a unidirectional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronic circuits from transient surges. It operates within a wide temperature range of -55°C to 175°C.
Key electrical characteristics include a 170V breakdown voltage and a 275V clamping voltage at 1.4A. The diode offers a peak pulse power dissipation of 400W for a 10/1000 µs waveform and 2.5 kW for an 8/20 µs waveform. It exhibits low leakage current, with a maximum of 0.2 μA at 25°C and 1 μA at 85°C.
This TVS diode is housed in a surface mount DO-221AC, SMA Flat Leads package, also known as SMAflat. Its planar technology ensures compatibility with high-end circuits requiring low leakage and high junction temperature stability for long-term reliability.
The SMA4F170A is suitable for general-purpose applications requiring robust protection against voltage transients.
