The STMicroelectronics SMA4F16A is a TVS (Transient Voltage Suppressor) diode from the SMA4F series, designed to protect sensitive electronic circuits from transient voltage surges. This unidirectional device features a peak pulse power dissipation of 400 W (10/1000 μs) and a stand-off voltage range from 5 V to 188 V.
Key electrical characteristics include a breakdown voltage of 16 V and a clamping voltage of 34.7 V at a peak pulse current of 15.4 A. The operating junction temperature range is -55 °C to 175 °C, ensuring reliability in demanding environments. Low leakage current is maintained at 0.2 μA at 25 °C.
This TVS diode is housed in a surface-mount DO-221AC, SMA Flat Leads package, also known as SMAflat. The lead finishing is matte tin plating. Its planar technology contributes to high junction temperature capability and long-term stability, making it suitable for high-end circuit applications requiring robust protection against voltage transients.
