The STMicroelectronics SMA6F31A is a TVS (Transient Voltage Suppressor) Diode designed to protect sensitive electronic circuits from transient voltage surges. It operates unidirectionally and is suitable for general-purpose applications.
Key electrical characteristics include a working voltage of 31V, a breakdown voltage of 36V, and a clamping voltage of 50.2V at a peak pulse current of 12.3A. The device offers a peak pulse power dissipation of 600W for a 10/1000 µs waveform and 4kW for an 8/20 µs waveform. It maintains low leakage current, with values of 0.2 µA at 25°C and 1 µA at 85°C.
The operating junction temperature range is from -55°C to +175°C, with a maximum operating temperature of 175°C. The device complies with IEC 61000-4-2 standards, exceeding level 4 for ESD protection with contact discharge up to 25 kV and air discharge up to 30 kV.
Packaged in a surface-mount SMAflat (DO-214AC) case, the SMA6F31A is designed for high-reliability applications requiring long-term stability. Lead finishing is matte tin plating, and it is compatible with standard SMT assembly processes.
